The Federal Reserve’s annual symposium in Jackson Hole, Wyoming, this week is turning attention to the sustainability of U.S. fiscal policy as budget deficits persist above 4% of gross domestic product for the fifth consecutive year.
The gathering comes amid growing scrutiny over the balance between monetary and fiscal authorities, with former Fed Chair Kevin Warsh and current Treasury Secretary Scott Bessent among those weighing in on potential solutions. Bessent has proposed expanding the Fed’s foreign central bank lending facility to mitigate volatility in the U.S. Treasury market, a move aimed at shielding domestic borrowing costs from external shocks.
Fiscal dominance—the reliance of governments on central bank support when fiscal space is exhausted—has resurfaced as a key topic. Historically, such arrangements have led to inflationary spirals, as seen in Weimar Germany and Argentina, where monetary financing was used to cover government deficits. Advanced economies have since formalized bans on direct monetary financing to prevent similar outcomes.
The U.S. experience since 2008 underscores the challenge. Public debt levels rose steadily after the financial crisis, and deficits have remained structurally high since 2019. Warsh, who left the Fed in 2010 in protest over its bond-buying programs, has previously highlighted the risks of prolonged monetary accommodation.
The Fed’s 2011 “Operation Twist”—a program that sold short-term Treasuries while buying longer-dated securities—illustrates how monetary policy can indirectly influence fiscal dynamics by lowering borrowing costs for Washington. The 1951 Treasury-Federal Reserve Accord restored the central bank’s independence after World War II, when the Fed had effectively capped government bond yields to finance wartime spending.
With global central banks including the European Central Bank and the Bank of Japan also grappling with fiscal pressures, the Jackson Hole discussions may shape future policy responses to the interplay between government spending, debt sustainability, and monetary stability.
