No matter where you bank, the prevailing interest rate environment will have an impact on your interest rate.
The amount banks are willing to pay on deposits is heavily influenced by the Federal Reserve, which sets the rate at which banks can loan money to each other. This is known as the Federal Funds Rate. It’s the rising tide that raises all rates, and the receding tide that can also bring them all down.
The Federal Reserve sets a target range for the Federal Funds Rate, rather than aiming for a specific number. Because of this, the Federal Funds Rate can change by a small amount from day to day. However, larger changes to the Federal Funds Rate can occur when the Federal Reserve changes its target range or when the Federal Reserve changes policies. The interest rate you receive on Cash Reserve typically will change as a result of these more significant shifts in the Federal Funds Rate.
