Question

Quizplus · Accepted Answer

In 2010, currency (physical money like coins and banknotes) constituted a little more than half of the money supply, reflecting the balance between physical currency and digital forms of money such as checkable deposits. The other options are incorrect because the money supply is primarily controlled by the Federal Reserve (not the United States Treasury), and while money does serve as a store of value, its most important roles are as a medium of exchange and a unit of account.
