What’s the problem? It seems we’re not exactly sure…

Some helpful notes:
– The term eurodollar refers to U.S. dollar-denominated deposits at foreign banks or at the overseas branches of American banks. Because they are held outside the United States, eurodollars are not subject to regulation by the Federal Reserve Board, including reserve requirements.
– The Federal Reserve Banks pay interest on required reserve balances and on excess reserve balances. … The interest rate on excess reserves (IOER rate) is also determined by the Board and gives the Federal Reserve an additional tool for the conduct of monetary policy.

Got phys? IMO its a good idea to keep it tucked away. You may need it.
