how to hedge against inflation

Uncontrolled government spending could force the Fed to monetize the government's debt, creating runaway inflation, former Federal Reserve Governor Frederic Mishkin warned in a report.

If these circumstances were to occur, the Fed would be unable to do much, if anything, to control inflation, Mishkin said in the report, presented at a conference at the University of Chicago Booth School of Business.

In that case, Mishkin and his co-authors, David Greenlaw, James Hamilton and Peter Hooper, argue that the result could be "a flight from the dollar," according to a summary of the report by noted Fed-watcher Steven K. Beckner writing for MNI.

The report states, "Countries with high debt loads are vulnerable to an adverse feedback loop in which doubts by lenders lead to higher sovereign interest rates, which in turn make the debt problems more severe ... Countries with debt above 80% of GDP and persistent current-account deficits are vulnerable to a rapid fiscal deterioration as a result of these tipping-point dynamics."

The authors of the report estimate U.S. net debt, excluding debt held by the Social Security Trust Fund, at about 80% of GDP in 2011, double what it was a few years before. To make matters worse, the United States runs a persistent current account deficit, which is funded by borrowing from other countries.

This puts the U.S. in a worse spot than Japan which, although its debt is much higher as a percentage of GDP, has a large current account surplus and a high savings rate.
