You open your banking app, look at the deposit rate, and think: “is that it?”. You are not alone. According to ECB data updated February 2026, the average rate on euro area household deposits is 0.25% on instant-access deposits and 1.77% on twelve-month locked deposits. Meanwhile, Eurostat shows annual euro area inflation hovering around 2.1%. In other words: net of average annual inflation, your bank savings deliver a negative real return.
This article walks you through, transparently and with verifiable sources, why DeFi yields can be structurally higher than bank yields, and the actual mechanics behind the “up to 7% APY” you see in unflat communications.
Where does the yield come from? The mechanics of the bank spread
Yield, in any standard banking system, comes from one place: someone paying interest on a loan.
When you deposit 10,000 euros in a bank, the bank uses that money to fund mortgages and corporate loans. The interest rates it earns sit historically in a 4 to 7% gross range. The bank keeps most of that yield to cover its costs. What ends up in your pocket is zero, very little, or even a fee for holding the account.
The technical word for this gap is “bank spread”. In the last few years, the European spread has widened: the ECB raised loan rates faster than banks raised deposit rates. Result: record margins on bank balance sheets, not much for the saver.
It is the bank’s business model: risk intermediation, low-cost funding, higher-cost lending. The problem is not the bank itself. The problem is that, until recently, there was no accessible alternative for choosing whether to give up that spread.
Why can DeFi pay more on the same lending market?
Decentralized finance enters here. DeFi is the same lending market viewed from the other side: without the bank in the middle, and with rules written in code instead of contracts.
The mechanism is more direct. On a decentralized lending protocol like Morpho Protocol, a borrower who needs liquidity for trading, leverage, or arbitrage deposits collateral (typically more than 150% of the requested amount) and pays a market-determined interest rate. That rate, net of small protocol fees, flows entirely to whoever supplied the funds.
The difference with the bank is structural. No branches, no traditional operating costs, no intermediation layer between capital and loan. Almost the entire spread stays with the lender. That is why, on the more liquid DeFi markets, a saver can see yields that are not “magic” but simply what is left once intermediaries are removed.
There is another important dynamic: liquidity demand on crypto markets keeps growing over time. Traders, institutions, investment funds (some of them, like Apollo Global Management, are moving directly onto the protocol) use these markets daily. That growing demand sustains rates that, historically, have moved in the 4 to 7% net APY range on the more mature vaults.
What is Morpho Protocol
Morpho Protocol is a decentralized lending infrastructure with over 5 billion dollars in managed assets, security audits performed by Trail of Bits, OpenZeppelin, Spearbit, and Certora, and zero protocol-level exploits to date.
If the collateral value drops below a threshold, smart contracts automatically liquidate the position and repay the lenders. The contracts are immutable, isolated per market, verifiable by anyone.
This is not a marketing promise. It is verifiable in real time: anyone can open DefiLlama or unflat’s technical documentation and check the numbers, audits, and flows.
How much does DeFi actually yield compared to a European deposit account in 2026?
Putting the numbers side by side removes any ambiguity.
Locked deposit account in the euro area in 2026: 1.77% on average over twelve months, with peaks above 3% only on long durations and at specialist banks. Current account: between 0% and 1% gross. From this, you must subtract national taxation on interest.
On unflat, historical yield, sourced from Morpho, has reached up to 7% net APY (net of protocol fees, before national taxation, which stays with the user according to local rules). The 7% rate is not guaranteed: in periods of low liquidity demand the rate falls, in periods of high demand it rises. It is the same transparent mechanism that moves the trading desks of banks, brought onto a track accessible to retail savers.
Remember: this is not a bank account. Deposits are not government-insured. Never deposit money you cannot afford to see decrease.
For a more systematic side-by-side, we dedicated a separate piece to the DeFi vs traditional banking comparison across 10 dimensions.
How unflat gives you access to DeFi yields without technical complexity
Historically, DeFi required three things that made it feel hard to access: a wallet with a seed phrase, a healthy dose of gas fees on every transaction, and enough technical knowledge to interact correctly without falling into risks like drainers, scams, or rug pulls. That is exactly the barrier we decided to launch unflat to remove.
On unflat, the flow is divided into four steps:
- You open an account with email and biometric authentication (Face ID or fingerprint). The smart account the app creates is a non-custodial wallet: keys are split into multiple shards distributed across your device, a personal cloud, and a third-party provider, so no single party can access the funds alone. Only you, by authenticating with biometrics, can sign transactions. To understand the story behind the product, read what unflat is: the story behind the fintech changing savings in Europe.
- You deposit USDC through Coinbase: unflat uses Coinbase as a regulated MiCA-licensed on/off ramp to convert euros into USDC and back. Alternatively, you can transfer USDC on-chain if you already hold it. unflat’s vision is euro-native: EURC support will arrive when EURC vaults on Morpho have sufficient liquidity.
- Funds are allocated to vaults curated by Morpho Protocol, selected on a risk and yield basis. Interest accrues in real time, second by second, visible in the app.
- You withdraw whenever you want, no lockup, no penalties, in minutes.
The experience feels like a next-generation savings app. The substance is a verifiable on-chain decentralized lending market. unflat is the bridge between the two worlds. For more deep dives, visit the unflat blog.
Conclusion
The reason unflat can offer higher yields than your bank is not a promise, it is an architectural choice. No branches, no intermediation layer, no invisible spread. The same lending mechanism banks use to generate margin, returned to the saver transparently.
Three things to take away. First: “up to 7% APY” is not magic, it is the result of removing intermediaries on an overcollateralized lending market. Second: the yield is variable, dependent on liquidity demand on the market. Third: everything is verifiable on-chain. You do not have to trust, you have to verify.
