# Why Fixed Rates Matter
Crypto has learned how to trade, lend, and speculate. What it still hasn’t learned—at least not well—is how to **lock in a rate**.
Today, most yields in DeFi are floating. Deposit USDC and your return changes day by day. Borrow against ETH and your cost can spike overnight. This works when markets are calm, but it breaks down the moment volatility rises or capital becomes scarce.
In traditional finance, this problem was solved decades ago. Current daily volume of Interest Rate Swaps (IRS) products reached $8 trillion. Corporate treasuries hedge interest rate exposure. Savers use fixed-term deposits. The entire fixed-income market exists to answer one basic question:
> *“What will my rate be over time?”*
Crypto doesn’t have a real answer yet. That’s what this protocol is built to change.
XCCY introduces **on-chain fixed rates**—not as a marketing promise, but as a real financial primitive—by bringing interest rate swaps, portfolio risk management, and bank-style balance sheet logic on-chain.
