Nobel economist Paul Krugman says minting a $1 trillion coin to prevent a debt ceiling crisis wouldn't be inflationary

• The US could mint a platinum coin to solve the debt crisis without worsening inflation, Paul Krugman said.
• The top economist said the inflationary effects of the coin would be offset by the Fed selling bonds.
• "But as I said, people who really should know better constantly get this wrong, and imagine that the coin would be inflationary."

A $1 trillion platinum coin could prevent the US government from defaulting on its debt without making inflation worse, according to Nobel laureate Paul Krugman.
