Paul, a longtime critic of the Federal Reserve and U.S. monetary policy, said he believes it's "a possibility" that there might not actually be any gold in the vaults of Fort Knox or the New York Federal Reserve bank.
The libertarian lawmaker told Kitco News, a website tracking news about precious metals, that an audit was necessary to determine how much the U.S. maintains in gold reserves in case the government were to use gold to back the dollar.
“If there was no question about the gold being there, you think they would be anxious to prove gold is there,” he said.
“Our Federal Reserve admits to nothing, and they should prove all the gold is there. There is a reason to be suspicious and even if you are not suspicious why wouldn’t you have an audit?
Paul had been one of the Republicans to spearhead a broader audit of the Fed as part of the Wall Street reform bill passed through Congress this year. The provision, which was weakened somewhat in the final version, found Paul joining with a number of Democrats to require the Fed to open its books and outline its assets and liabilities.
The gold reserves, which Paul's new bill would audit, are generally seen as a guarantee on a nation's currency, but the U.S. moved the dollar away from being tied to the price of gold in 1972.
Paul stopped short of calling for the reinstitution of the gold standard and instead called for the government to allow the use of hard currency — gold and silver tender — alongside the use of the dollar.
"If people get tired of using the paper standard they can deal in gold or silver,” he said.
