Morpho Midnight's orderbook is going to be one of the venues that matters most for reading DeFi rates. It gives crypto credit something it's never had: a term structure. Fixed rates at fixed maturities, set by an orderbook instead of a utilization curve.

TradFi has always priced credit this way. An overnight rate anchors the front (repo, the policy rate), and a curve of term rates prices duration out along bills, notes, and bonds. DeFi has lived entirely at the overnight point, floating rates that reprice every block. Midnight adds the rest of the curve.
Liquidity is still thin, but the appetite is already visible on both sides. Borrowers and lenders are quoting real size, and the lend curve slopes up with duration: longer maturities clear at higher rates, the same contango shape a healthy bond market prints when lenders want a premium for locking up.
The cbBTC book on Base is clearing fixed borrow rates around 3-6% depending on tenor today. I expect discovery across maturities to get far more efficient as market makers move in, and the front of the curve to converge with Morpho Blue, which is the perpetual floating DeFi rate right now. Currently, BTC loans are at 3%-5% yield on Ethereum and Base on Blue.
It's early. This is a three-point curve on one collateral, and the far tenors are barely quoted. But the direction is clear: crypto is getting a market-priced yield curve.
