A short map of open banking: what APIs open up, why banks and fintechs argue over data and which signals matter for the market.
Open banking is the shift from closed banking perimeters to managed exchange of data and payment actions via APIs. For fintech it is not just technology but a new competition for a convenient customer scenario.
The user gets more chances to manage their financial data and actions from different interfaces: a bank, a wallet, an accounting service, a marketplace or a business app.
The main value is not in the API itself, but in the fact that a payment, a balance check, scoring or income verification can become part of a shorter product.
Banks retain an important role as holders of accounts, infrastructure and trust. But on top of them room appears for specialized services: PFM, merchant tools, credit storefronts, accounting, payment integrators and B2B fintechs.
The Kazakh market is already used to strong banking apps. That is why open banking here matters not as a replacement for banks, but as a way to build more open infrastructure around them for new services.
If the rules and technical standards are clear, the market will be able to develop products for SMEs, cross-border scenarios, scoring and personal financial services faster.
Open banking strengthens the market only when there is trust in security, clear user consent and transparent liability. Otherwise the API easily turns into a formal integration that almost no one uses.
No. In a normal model, data and actions are opened only within the framework of rules, user consent and technical security standards.
Open banking usually starts with bank accounts and payments. Open finance is broader: it can include insurance, investments, credit data, wallets and other financial services.
The user — through more convenient services; fintechs — through access to infrastructure; banks — if they turn the API into a partner channel rather than merely an obligation.
