Why it matters
The large capital allocation highlights growing institutional interest in Bitcoin-backed lending products. It also demonstrates the integration of decentralized finance protocols like Spark with specific asset-backed lending platforms.
The cbBTC/USDC market reports a total supply of $1.77 billion against $1.60 billion in borrowed assets, maintaining a utilization rate above 90%. Current lending conditions feature a 4.73% supply APY and a 5.26% borrow interest rate.
