Many in the financial press have noted the rise since September 2008 in the Fed’s reserve balances from about $20 billion to more than $800 billion today. A number of well-known economists have expressed concern that this will be inflationary.
However, fears that these are inflationary are misplaced, even inapplicable, as they apply only to a monetary system operating under a gold standard, currency board, or similar arrangement, not the flexible exchange rate system of the U. S.
Under a gold standard, for instance, banks must be careful when creating loans that they have sufficient gold or central bank reserves to meet depositor outflows or legal reserve requirements. This is the fractional banking, money multiplier system standard in the economics textbooks. If there is an inflow of gold, then bank deposit creation can increase and prices can rise. The same can occur if the central bank raises the quantity of reserves circulating relative to its own gold reserves.
