Introduction
Fintech advertising in Turkey has become a major legal and regulatory issue. Payment institutions, electronic money institutions, digital wallets, crypto asset service providers, investment platforms, crowdfunding platforms, digital lending providers, insurance technology companies, Banking-as-a-Service interfaces, open banking apps, and financial comparison platforms all use digital marketing to acquire customers. They advertise through Google search ads, social media campaigns, influencer videos, mobile notifications, referral programs, affiliate links, comparison websites, e-mail campaigns, SMS messages, YouTube content, app store descriptions, and in-app banners.
However, financial advertising is not ordinary marketing. Fintech products affect money, savings, borrowing, investment decisions, payment security, consumer data, and financial risk. A misleading statement about a wallet, loan, crypto asset, cashback offer, investment app, or payment product can cause direct consumer harm. A vague promise such as “guaranteed return,” “risk-free crypto,” “instant loan approval,” “free money,” “licensed by the state,” “bank-level security,” or “zero cost” may create regulatory, civil, administrative, and reputational exposure.
In Turkey, fintech advertising is governed by several overlapping legal regimes. The general consumer advertising framework is based on Law No. 6502 on Consumer Protection, especially Articles 61, 62, and 63 on commercial advertising, unfair commercial practices, and the Advertisement Board. The law requires advertisements to be honest and truthful and prohibits advertisements that deceive or mislead consumers or abuse their lack of experience or knowledge. It also prohibits implicit advertising and requires advertisers to prove material claims made in their advertisements.
For influencer marketing, the Ministry of Trade’s guideline on social media influencers applies to consumer commercial advertising and commercial practices made by influencers. The guideline is based on Law No. 6502, the Regulation on Commercial Advertising and Unfair Commercial Practices, and the Advertisement Board’s principle decision dated 4 May 2021. It requires influencer advertisements to be clearly and distinguishably expressed and prohibits covert advertising on social media.
For regulated fintech sectors, additional rules apply. Payment and electronic money institutions operate under Law No. 6493 and require authorization from the Central Bank of the Republic of Türkiye, while crypto asset service providers are now subject to the Capital Markets Board framework. Payment and e-money institutions may only act within the scope of their CBRT license, and they are subject to CBRT supervision and MASAK audits.
This article explains fintech advertising rules in Turkey, including misleading financial promotions, influencer campaigns, crypto advertising, payment and e-money marketing, digital lending claims, cashback campaigns, consumer protection, platform liability, and practical compliance steps for fintech companies.
1. Why Fintech Advertising Is Legally Sensitive
Fintech advertising is legally sensitive because consumers often make financial decisions quickly based on digital messages. A user may open a wallet account after seeing an influencer story. A consumer may apply for a loan after reading “instant approval.” A crypto investor may buy a token because a platform claims “listed on a regulated platform.” A merchant may choose a payment service provider because the company advertises “zero commission.” A customer may trust a digital wallet because the app says “bank-level protection.”
These statements are not harmless slogans if they influence financial decisions. Turkish consumer law treats commercial advertisements broadly. Article 61 of Law No. 6502 defines commercial advertisement as marketing communication made through written, visual, audio, or similar methods in any medium to promote the sale or lease of goods or services, or to inform or persuade the target audience.
This broad definition is important for fintech because almost every digital communication may qualify as advertising: app store text, push notifications, influencer content, comparison charts, sponsored search results, landing pages, promotional videos, referral banners, and even educational-looking posts if they promote a fintech service.
The central legal risk is that fintech advertisements may simplify complex financial products in a way that misleads consumers. Fintech marketing must therefore be accurate, balanced, documented, and consistent with the company’s license, product terms, fees, risks, and actual technical capacity.
2. Main Legal Framework for Fintech Advertising in Turkey
Fintech advertising in Turkey may involve the following legal sources:
Law No. 6502 on Consumer Protection
Regulation on Commercial Advertising and Unfair Commercial Practices
Ministry of Trade influencer advertising guideline
Law No. 6493 on payment services and electronic money
CBRT regulations and licensing framework
Capital Markets Law and CMB communiqués
Crypto asset service provider rules
Banking Law and BRSA rules where bank-related products are advertised
Law No. 6698 on Protection of Personal Data
Law No. 5549 on Prevention of Laundering Proceeds of Crime
Consumer credit rules
E-commerce and electronic communication rules
Advertising Board decisions
Turkey does not have one single “fintech advertising code.” Instead, the applicable rules depend on the product. A crypto advertisement may involve CMB rules. A wallet advertisement may involve CBRT licensing and e-money rules. A digital loan advertisement may involve consumer credit and banking or financing company rules. A robo-advisory advertisement may involve capital markets rules. An InsurTech advertisement may involve insurance regulation. A cashback wallet advertisement may involve payment services, electronic money, consumer law, and advertising law.
The first compliance step is product classification. A fintech company must know exactly what it is advertising before approving the marketing message.
3. General Rule: Advertisements Must Be Honest and True
The basic rule under Turkish consumer law is clear: commercial advertisements must be honest and true. Article 61 of Law No. 6502 states that commercial advertisements must comply with the principles adopted by the Advertisement Board, public morality, public order, personal rights, and must be honest and true. Advertisements that deceive or mislead consumers or abuse consumers’ lack of experience or knowledge are prohibited.
This rule is especially important in fintech because consumers may not fully understand the difference between:
A bank and a fintech interface.
A payment institution and an electronic money institution.
A wallet balance and a bank deposit.
A crypto asset and legal tender.
A cashback coupon and cash refund.
An investment recommendation and general information.
A licensed platform and a regulated product.
A “zero fee” campaign and a product with hidden spreads or merchant charges.
Fintech advertising should avoid ambiguity. If the product is not a bank deposit, it should not be presented as one. If returns are not guaranteed, the advertisement should not imply certainty. If the company is not a bank, the brand language should not suggest that it is. If a cashback reward is usable only under certain conditions, those conditions must be clear.
4. Misleading Financial Promotions
A financial promotion is misleading if it creates a false or incomplete impression about the product, provider, cost, risk, license status, security, return, availability, or consumer rights.
Examples of risky fintech advertising claims include:
“Guaranteed return” for investment or crypto products.
“Risk-free trading” for volatile assets.
“Zero cost” where fees, spreads, or commissions apply.
“Instant approval for everyone” where credit assessment is required.
“State-approved investment” where only the platform is licensed.
“Bank guarantee” where funds are not bank deposits.
“Free cashback” where minimum spending, expiry, or product exclusions apply.
“Withdraw anytime” where compliance checks, settlement periods, or limits apply.
“Licensed fintech” without identifying the relevant license and scope.
“Best rate in Turkey” without objective, current, and verifiable evidence.
“Your money is fully protected” where protection is limited.
Fintech companies should review all express and implied claims. A claim may be misleading even if each word is technically true, if the overall impression is deceptive.
5. Burden of Proof for Advertising Claims
One of the most important rules for fintech marketing teams is that material advertising claims must be provable. Article 61 of Law No. 6502 provides that advertisers must prove the material claims made in their commercial advertisements.
This has practical consequences. A fintech company should keep evidence before publishing claims such as:
“Lowest commission.”
“Fastest transfer.”
“Most secure wallet.”
“Highest cashback.”
“Best exchange rate.”
“No hidden fees.”
“Licensed and supervised.”
“Thousands of merchants.”
“Instant settlement.”
“Artificial intelligence-based fraud protection.”
“Bank-grade encryption.”
“24/7 uninterrupted service.”
The evidence should be current, objective, and relevant to the exact claim. If the advertisement says “lowest fee,” the company should be able to prove the comparison methodology, date, competitors reviewed, product category, and fee calculation. If the advertisement says “licensed by the CBRT,” the company should ensure that the license exists and that the advertised product falls within the license scope.
6. Advertisement Board Powers and Sanctions
The Advertisement Board is the main administrative authority for commercial advertisements and unfair commercial practices under Law No. 6502. Article 63 establishes the Advertisement Board to determine advertising principles, protect consumers against unfair commercial practices, review and inspect advertisements, order suspension or correction, impose administrative fines, and issue precautionary suspensions for up to three months where necessary.
For fintech companies, this means misleading advertisements can lead not only to consumer complaints but also to administrative intervention. The Advertisement Board may require the advertisement to be corrected or suspended. Administrative fines may also apply, and repeated violations may lead to increased exposure.
A fintech company should therefore treat advertising compliance as part of regulatory risk management. Marketing review should involve legal, compliance, product, and risk teams before launch, especially for financial claims, influencer campaigns, crypto products, lending campaigns, or high-volume customer acquisition campaigns.
7. Unfair Commercial Practices
Law No. 6502 prohibits unfair commercial practices directed at consumers. A commercial practice is unfair if it does not comply with professional care requirements and significantly affects, or is likely to affect, the economic behavior of the average consumer or target group. Deceptive and aggressive practices are especially treated as unfair commercial practices, and the party engaged in the practice bears the burden of proving that it is not unfair when challenged.
In fintech, unfair commercial practices may include:
Pressuring consumers to take loans quickly.
Using countdown timers misleadingly.
Hiding key fees until the last step.
Making cancellation or withdrawal difficult.
Using dark patterns in wallet sign-up flows.
Presenting optional insurance as mandatory.
Using complex legal disclaimers to hide simple commercial truth.
Encouraging inexperienced users to trade high-risk assets.
Targeting vulnerable consumers with aggressive credit offers.
Making it difficult to close an account or withdraw balance.
Fintech apps often rely on behavioral design. That design must not cross into manipulation. A smooth user experience is lawful; a deceptive user journey is not.
8. Covert Advertising and Native Content
Covert advertising is expressly prohibited. Article 61 of Law No. 6502 treats promotional use of names, brands, logos, or other identifying symbols in articles, news, or programs without clearly stating that the content is advertising as implicit advertisement, and prohibits implicit advertisements in all communication tools.
This is important for fintech because many promotions are disguised as:
Educational videos.
Investment tips.
“Personal experience” posts.
Founder interviews.
Crypto market analysis.
Comparison articles.
Financial literacy content.
Influencer tutorials.
“Best apps” lists.
Podcast mentions.
Native advertising is not unlawful merely because it resembles editorial content. The problem arises when the commercial relationship is hidden or when the content persuades consumers without clearly disclosing its advertising nature. A fintech company sponsoring content must ensure the advertising character is clear.
9. Influencer Marketing in Fintech
Influencer marketing is common in fintech, especially for crypto platforms, wallets, trading apps, payment cards, cashback campaigns, digital lending, insurance apps, and investment education. The Ministry of Trade’s influencer guideline covers consumer commercial advertising and commercial practices by social media influencers and was prepared based on Law No. 6502, the Regulation on Commercial Advertising and Unfair Commercial Practices, and the Advertisement Board’s principle decision.
The guideline defines a social media influencer as a person who undertakes marketing communication through a social media account to sell, rent, inform, or persuade the target audience regarding goods or services. It also requires influencer advertisements to be clearly and distinguishably expressed and prohibits covert product placement on social media.
For fintech, this means influencer posts must disclose the commercial relationship where the influencer receives payment, free services, discounts, referral benefits, tokens, commission, campaign codes, or other benefits. Disclosure must be visible, understandable, and platform-appropriate.
Fintech influencer compliance should include:
Written influencer contracts.
Mandatory advertising disclosure language.
Pre-approval of claims.
Prohibition on guaranteed return claims.
Prohibition on misleading license claims.
Risk warning requirements.
No fake personal experience.
No undisclosed referral links.
No performance screenshots without context.
No targeting of unsuitable audiences.
A fintech company should not allow influencers to improvise financial claims.
10. Crypto Advertising
Crypto advertising is one of the highest-risk areas of fintech marketing in Turkey. Crypto assets are volatile, technically complex, and often misunderstood by retail users. The CMB’s 2025 crypto asset service provider framework regulates crypto asset platforms and related service providers, and legal summaries explain that non-resident crypto asset service providers may only serve Turkish residents on a reverse-solicitation basis if they do not engage in promotion, advertising, or marketing directed at residents in Türkiye.
This is significant for foreign crypto platforms. A foreign platform should not assume that it can freely run Turkish-language campaigns, use Turkish influencers, open Turkish social media accounts, or target Turkish residents without regulatory consequences. Legal commentary notes that non-resident crypto asset service providers cannot open a workplace in Türkiye, create a Turkish website, or conduct promotional and marketing activities directed at residents in Türkiye if they rely on reverse solicitation.
Risky crypto advertising claims include:
“Guaranteed profit.”
“No risk.”
“Safe passive income.”
“Government-approved coin.”
“CMB-approved token.”
“100x opportunity.”
“Earn daily fixed returns.”
“Zero loss trading bot.”
“Stablecoin equals dollar deposit.”
“DeFi yield with no risk.”
Crypto advertisements should explain that crypto assets may lose value, liquidity may disappear, platform services may be restricted, withdrawals may be delayed due to AML or technical issues, and past performance does not guarantee future results.
11. Payment and E-Money Advertising
Payment institutions and electronic money institutions must advertise within the scope of their license. TÖDEB states that payment institutions and electronic money institutions operate with a CBRT license and must satisfy criteria such as sufficient personnel and technical equipment, complaint and appeal units, continuity measures, and security and confidentiality measures for funds and user information.
Advertising should accurately identify the institution’s regulatory status. A payment institution should not present itself as a bank. An electronic money institution should not suggest that wallet balances are bank deposits. A payment gateway should not imply that it provides investment services. A digital wallet should not suggest unlimited fund protection if protection is legally limited.
Risky payment and e-money claims include:
“Bank account alternative” without proper explanation.
“Your money is guaranteed like a bank deposit.”
“Unlimited wallet protection.”
“Instant settlement always.”
“No fees” where merchant fees or withdrawal charges apply.
“Licensed financial institution” without specifying license type.
“Safe for all payments” where certain activities are prohibited.
“Use crypto for payment” despite Turkish payment restrictions.
Marketing must align with the company’s CBRT license and actual product terms.
12. Digital Lending Advertising
Digital lending advertisements require special care because credit can increase consumer indebtedness. Claims such as “instant loan,” “loan without checks,” “approval for everyone,” “zero interest,” or “free credit” may be misleading if conditions, fees, commissions, insurance costs, or creditworthiness checks apply.
A digital lending advertisement should clearly disclose:
The lender identity.
Whether approval is subject to assessment.
Interest rate and total cost where applicable.
Fees and commissions.
Installment amount.
Campaign conditions.
Withdrawal rights where relevant.
Insurance or ancillary product terms.
Default consequences.
Whether the fintech is a lender or interface provider.
A fintech platform that only refers customers to a bank or financing company should not present itself as the creditor. If the advertisement says “we give loans,” but the loan is actually provided by a bank, customer confusion may create regulatory and consumer protection risk.
13. Investment App and Robo-Advisory Advertising
Investment apps, trading platforms, robo-advisors, and portfolio tools must be careful not to provide unauthorized investment advice through advertising. “Buy this stock,” “this fund is best for you,” “AI will grow your money,” “safe passive income,” or “guaranteed portfolio return” may raise capital markets compliance issues.
Investment advertising should distinguish between:
General financial education.
Market commentary.
Investment research.
Personalized investment advice.
Portfolio management.
Order execution.
Robo-advisory.
Capital markets activities are regulated by the CMB. Fintech advertising should not lead consumers to believe that a platform is authorized to provide investment advice or portfolio management unless it is legally authorized to do so.
14. Cashback, Rewards, and “Free Money” Claims
Cashback and reward campaigns are popular in fintech. Digital wallets, payment cards, marketplaces, loyalty apps, and banks often advertise cashback, points, coupons, and referral bonuses.
These claims are risky when they use words like:
“Cash.”
“Free money.”
“Guaranteed reward.”
“Withdrawable balance.”
“Spend anywhere.”
“No conditions.”
If cashback is not withdrawable as cash, that should be clear. If points expire, the expiration must be disclosed. If rewards apply only to selected merchants, the limitation should be visible. If referral rewards are subject to fraud checks, the condition should be included.
A campaign that says “earn 500 TL” may mislead consumers if the benefit is actually a non-transferable coupon, usable only after minimum spending, valid for a limited period, and not redeemable for cash.
15. “Licensed” and “Regulated” Claims
Fintech companies often use license status as a marketing advantage. This is lawful if accurate, but risky if exaggerated.
A company should specify:
Which authority issued the license.
Which entity holds the license.
What activities the license covers.
Whether the advertised product is within license scope.
Whether a partner or the visible brand is licensed.
Whether the license means product approval or only institutional authorization.
For example, a CBRT license for payment services does not mean that every commercial claim, reward program, investment offer, or crypto-related service is approved by the state. A CMB-regulated crypto platform should not suggest that the CMB guarantees the value of listed assets. A BaaS interface provider should not suggest that it is a bank if the licensed service provider is the bank.
License-related claims should be factual, precise, and not used to create false confidence.
16. Risk Disclosures in Fintech Advertising
Financial promotions should include risk disclosures where the product involves financial risk, fees, volatility, credit obligations, transfer restrictions, data risks, or market uncertainty.
Risk disclosures should be:
Visible.
Understandable.
Close to the main claim.
Not hidden in tiny text.
Consistent with the product.
Specific enough to inform the consumer.
Risk disclosures are especially important for:
Crypto trading.
Investment apps.
Robo-advisory.
Crowdfunding.
Digital lending.
BNPL.
Stablecoins.
DeFi products.
High-yield campaigns.
Foreign exchange or commodity-linked products.
A statement like “investment involves risk” may not be enough if the advertisement promises high returns. The disclosure must correct the overall impression, not merely appear as formal legal text.
17. Social Media, Referral Codes, and Affiliate Marketing
Fintech companies often use referral and affiliate campaigns. Users, influencers, or affiliate publishers share a code or link and receive commission, cashback, tokens, or points when a new customer signs up.
Referral and affiliate campaigns create risks:
Undisclosed commercial relationship.
Exaggerated earnings claims.
Fake testimonials.
Misleading “personal experience” content.
Promotion to unsuitable audiences.
Uncontrolled financial claims by affiliates.
Unlawful spam or electronic communication.
Data protection issues.
Referral campaigns should have written rules. The company should monitor affiliate content, require disclosure, prohibit misleading claims, and reserve the right to terminate non-compliant affiliates.
If an affiliate says “this app gives guaranteed income,” the fintech company may face scrutiny even if the official website is compliant. A fintech company cannot ignore the marketing ecosystem it creates.
18. Comparative Advertising
Comparative advertising can be lawful if it is fair, accurate, objective, and verifiable. In fintech, comparisons may involve fees, transfer speeds, cashback amounts, exchange rates, merchant commissions, app ratings, security features, or loan costs.
A comparative fintech advertisement should disclose:
The comparison date.
The competitors compared.
The product category.
The calculation method.
The assumptions.
Whether temporary campaigns are included.
Whether fees, spreads, and taxes are considered.
Whether the comparison is still current.
A statement such as “lowest commission in Turkey” is risky if the company has not reviewed all relevant competitors or if hidden fees make the claim inaccurate. Comparative advertising must not selectively present data in a way that misleads consumers.
19. Advertising to Vulnerable Consumers
Fintech advertisers should be careful when products may affect vulnerable consumers. Law No. 6502 specifically prohibits advertisements that abuse the sick, elderly, children, or disabled persons, and more generally prohibits misleading practices that abuse consumers’ lack of experience or knowledge.
Vulnerability may be relevant in:
High-cost credit.
Debt consolidation.
Emergency loan ads.
Crypto speculation.
Gambling-like trading interfaces.
Investment apps targeting young users.
Health-related insurance fintech.
Financial distress campaigns.
Products advertised as “solution to urgent cash problems.”
Fintech companies should avoid exploiting fear, urgency, desperation, or lack of financial literacy. Responsible financial advertising should inform, not manipulate.
20. App Store Descriptions and Push Notifications
Fintech compliance should not focus only on formal advertisements. App store descriptions, screenshots, update notes, push notifications, onboarding screens, and in-app banners are also marketing communications if they persuade users.
Risky examples include:
“Open your bank account instantly” where the app is not a bank.
“Invest safely with AI” without risk disclosure.
“Your money is guaranteed” without legal basis.
“Only today: borrow now” without cost information.
“Your crypto will grow daily” without volatility warnings.
“Cashback credited instantly” where approval takes days.
Push notifications are particularly risky because they create urgency. A push notification encouraging financial action should be short but not misleading. If material conditions cannot fit in the notification, the notification should link to clear campaign terms before the user acts.
21. Data Protection in Personalized Advertising
Fintech advertising often uses personal data. A wallet may target users based on spending patterns. A lending platform may target users based on repayment behavior. A marketplace may promote BNPL to customers with high cart abandonment. A crypto app may target users who hold stablecoins. These practices trigger KVKK analysis.
Personalized advertising may involve:
Transaction history.
Device identifiers.
Location data.
Income indicators.
Credit behavior.
Merchant categories.
Wallet balances.
Investment activity.
Risk scores.
Referral behavior.
Under KVKK, personal data must be processed lawfully, fairly, for specified purposes, and proportionately. Fintech companies should inform users, establish lawful basis, respect consent requirements where applicable, control data sharing with ad networks, and avoid excessive profiling.
Financial data is particularly sensitive in practice. It may reveal lifestyle, health expenses, debt, family status, travel, political spending, or religious donations. Using such data for targeted advertising without proper safeguards may create serious legal risk.
22. Dark Patterns in Fintech Marketing
Dark patterns are manipulative design practices that push users into decisions they might not otherwise make. In fintech, dark patterns can be especially harmful because they may lead users to borrow money, invest, trade, subscribe, or share financial data.
Examples include:
Hiding “decline” buttons.
Pre-selecting optional insurance.
Making account closure difficult.
Using fake scarcity.
Using misleading countdowns.
Making fees visible only after commitment.
Presenting risky products as default choices.
Using confusing consent screens.
Designing cancellation flows to discourage exit.
Turkish unfair commercial practice rules are broad enough to capture manipulative digital conduct where it significantly affects consumer economic behavior. Fintech UX design should be reviewed by legal teams, not only growth teams.
23. Recordkeeping and Evidence
Advertising compliance requires evidence. A fintech company should preserve:
Advertisement copies.
Publication dates.
Targeting criteria.
Approved scripts.
Influencer contracts.
Influencer posts and stories.
Campaign terms.
Fee tables.
Risk disclosures.
Internal approval records.
Evidence supporting claims.
Comparison methodology.
Consumer complaint records.
Correction or takedown actions.
Social media monitoring records.
If a regulator questions an advertisement months later, the company should be able to reconstruct exactly what was published, to whom, when, and on what basis.
This is particularly important for social media stories and temporary posts, which disappear quickly. Fintech companies should archive influencer content and campaign materials.
24. Practical Compliance Checklist for Fintech Advertising in Turkey
A fintech company advertising in Turkey should consider the following checklist:
Classify the advertised product before launch.
Identify applicable regulators: Ministry of Trade, CBRT, CMB, BRSA, SEDDK, KVKK Authority, MASAK.
Confirm the advertiser’s license status and license scope.
Avoid bank-like language if the company is not a bank.
Avoid guaranteed return claims.
Avoid risk-free claims for investment, crypto, lending, or trading products.
Disclose fees, spreads, costs, and campaign conditions clearly.
Make cashback and reward conditions visible.
Use clear risk disclosures.
Pre-approve influencer scripts.
Require influencer advertising disclosures.
Monitor affiliate and referral content.
Prove all factual claims before publication.
Archive all advertisements.
Review comparative claims carefully.
Avoid dark patterns.
Prepare complaint handling procedures.
Review data use in personalized advertising under KVKK.
Coordinate marketing, legal, compliance, product, and customer support.
This checklist should be adapted to the fintech vertical. A payment app, e-money wallet, crypto platform, digital lender, investment app, InsurTech provider, or open banking platform will not have identical advertising risks.
Why Legal Support Is Important
Fintech advertising in Turkey requires legal support because marketing content may trigger consumer protection law, payment services regulation, capital markets rules, crypto regulation, banking rules, data protection, AML concerns, and unfair commercial practice enforcement.
A fintech lawyer can assist with:
Advertising law review.
Influencer contract drafting.
Crypto promotion compliance.
Payment and e-money advertising review.
Digital lending campaign review.
Risk disclosure drafting.
License claim verification.
Cashback and reward campaign terms.
Comparative advertising review.
KVKK analysis for targeted advertising.
Dark pattern risk assessment.
Advertisement Board defense.
Consumer complaint strategy.
Regulatory correspondence.
Legal review should take place before publication. Correcting a misleading campaign after it goes viral may not prevent regulatory action, consumer complaints, or reputational harm.
Conclusion
Fintech advertising in Turkey must be accurate, transparent, documented, and consistent with regulatory permissions. Financial promotions are not ordinary brand slogans. They influence decisions about money, credit, payments, investments, crypto assets, wallet balances, insurance, and personal data.
Law No. 6502 requires commercial advertisements to be honest and true, prohibits misleading advertisements and covert advertising, places the burden on advertisers to prove material claims, and empowers the Advertisement Board to order suspension, correction, administrative fines, and precautionary suspension where necessary. The Ministry of Trade’s influencer guideline also requires influencer advertisements to be clear and distinguishable and prohibits covert social media advertising.
For fintech companies, the main legal rule is substance over slogan. A payment institution should not advertise like a bank. A wallet should not be marketed as a deposit account. A crypto platform should not imply guaranteed returns. A digital lender should not hide credit costs. A cashback program should not call a limited coupon “cash” without explanation. An influencer should not promote a fintech product without disclosing the commercial relationship.
A legally strong fintech advertising strategy is built on four principles: truth, clarity, evidence, and proportionality. Every claim should be true. Every material condition should be clear. Every factual statement should be provable. Every promotion should be proportionate to the consumer’s financial risk.
In Turkey’s rapidly growing fintech market, trust is a competitive advantage. Companies that advertise responsibly will be better positioned to satisfy regulators, protect consumers, reduce disputes, and build sustainable financial brands.
