Treasury Secretary Scott Bessent is now pressuring Japan to rein in government spending and restore credibility with the bond market as Japanese yields surge. Reuters reports that Bessent confronted Japanese officials over what Washington sees as an inconsistent combination of aggressive fiscal spending and monetary policy, warning that instability in Japan’s enormous government bond market could spill directly into U.S. Treasuries. Japan’s 10-year government bond yield has climbed above 3%, reaching levels not seen since 1996, as investors increasingly demand greater compensation to finance one of the most indebted governments in the world.
Bessent understands the problem perfectly when he looks at Japan. Government cannot continue borrowing endlessly, suppress interest rates, manipulate its currency, and assume global capital will sit there forever accepting whatever return politicians decide to offer. Japan has spent decades experimenting with virtually every form of monetary manipulation imaginable. The Bank of Japan pushed rates below zero, bought enormous quantities of government bonds, controlled the yield curve, and expanded its balance sheet until it became one of the dominant holders of Japanese government debt. None of that eliminated the debt because it merely postponed the day when the market would again determine the price.
Japan’s government debt remains above 200% of GDP, and rising yields dramatically change the arithmetic. When rates were near zero, Tokyo could carry an enormous debt load because servicing costs remained artificially suppressed. Once yields rise, refinancing becomes progressively more expensive. The government then must issue still more debt to cover interest expenses, cut spending, raise taxes, or find new buyers willing to finance the entire operation.
What makes Bessent’s warning remarkable is that Washington is confronting the same fundamental problem. The United States has surpassed $40 trillion in federal debt, the Treasury must continuously refinance existing obligations while financing new deficits, and the 10-year Treasury yield has been testing levels around 5%. Bessent has simultaneously expanded Treasury buybacks in an effort officially aimed at improving liquidity while clearly recognizing the political and financial importance of preventing disorder in long-term government debt.
He is therefore telling Japan something Washington desperately needs to hear itself: the bond market eventually demands fiscal credibility. Bessent is especially concerned because Japan does not exist in some isolated financial universe. Japanese institutions are among the world’s largest foreign investors and major holders of U.S. assets, including Treasuries. When Japanese yields were virtually zero, enormous amounts of Japanese capital moved abroad searching for returns. If yields at home become sufficiently attractive, some of that capital has less reason to remain overseas. That is where Japan’s debt crisis can become America’s problem because capital can begin returning home precisely when Washington needs enormous amounts of foreign money to finance its own deficits.
