How many dollars is the total money supply?

Could you please clarify what you mean by "the total money supply"? Are you referring to the total amount of physical currency in circulation, or the broader monetary aggregates that include both physical currency and various types of bank deposits? If we're talking about the former, the exact figure can vary greatly depending on factors such as economic growth, inflation, and government policies. However, if we're discussing the broader monetary aggregates, there are several measures used by central banks and economists, such as M0, M1, M2, and M3, which include varying degrees of bank deposits in addition to physical currency. Could you specify which measure you're interested in, and what country or region you're referring to?
