J.P. Morgan, like other banks, earns revenue primarily through services such as loan interest, investment services, fees, and trading activities. Simply receiving deposits doesn’t directly contribute to a bank’s revenue, as the bank does not "earn" from holding the deposit itself. Deposits are typically used to fund other activities (e.g., issuing loans), which generate revenue.
In this case, the $1 million deposit is just a liability on the bank’s balance sheet and does not directly generate income for J.P. Morgan. Hence, the revenue from this specific deposit would be negligible for the bank.
