The Greenspan-Guidotti rule

.. says: The minimum benchmark of reserves equal to at least 100% of short-term external debt. But, The U.S. holds gold, oil, and foreign currency in reserve. It has 8,133.5 metric tonnes of gold (it is the world's largest holder). At current dollar values, it's worth around $300 billion. The U.S. strategic petroleum reserve shows a current total position of 725 million barrels. At current dollar prices, that's roughly $58 billion worth of oil. And according to the IMF, the U.S. has $136 billion in foreign currency reserves. So altogether... that's around $500 billion of reserves. Our short-term foreign debts are far bigger. According to the U.S. Treasury, $2 trillion worth of debt will mature in the next 12 months. So looking only at short-term debt, we know the Treasury will have to finance at least $2 trillion worth of maturing debt in the next 12 months. That might not cause a crisis if we were still funding our national debt internally. But since 1985, we've been a net debtor to the world. Today, foreigners own 44% of all our debts, which means we owe foreign creditors at least $880 billion in the next 12 months – an amount far larger than our reserves. Keep in mind, this only covers our existing debts. The Office of Management and Budget is predicting a $1.5 trillion budget deficit over the next year. That puts our total funding requirements on the order of $3.5 trillion over the next 12 months.
