The bank said that a key risk for Coinbase realizing its interest income is the possibility of reduced holding of USDC and fiat currency with the exchange. “We see the potential for institutional investors to hold less USDC given the opportunity cost of holding quasi-cash that doesn’t offer a yield. We also see retail holding less of its fiat at Coinbase since it doesn’t get a yield. As such, we see the potential for USDC balances and fiat balances to decline for Coinbase,” JPMorgan wrote.
