US-Japan Bond Yields Surge Amid Inflation Fears and Fiscal Policy Slack

The US and Japan are on a collision course as their bond yields surge. The Japanese government's debt-to-GDP ratio is over 250%, making it a concern for global markets. Benchmark yields in Japan have hit 3% for the first time, and long-term US Treasury yields are climbing to two-decade highs near 5.3%. This move has rattled global markets and caused sharp swings in the yen.

The plot thickens as US Treasury Secretary Scott Bessent escalates his campaign pressuring the Bank of Japan to raise rates. However, Tokyo's response has been muted, leaving many wondering if the Japanese government will do 'the right thing' on monetary policy to reverse the yen's slide. The BOJ Governor Kazuo Ueda was called upon by Bessent to take action and stabilize the yen.

The situation is compounded by rising inflation fears due to the ongoing war in Iran and oil prices above $95 a barrel. Additionally, fiscal policy has gone slack, and central banks are struggling to keep up with tightening measures. This dynamic has become increasingly entangled in geopolitics between Washington and Tokyo, raising the stakes for world markets.

The trajectory of US government debt is also cause for concern. With national debt above $40 trillion and a debt-to-GDP ratio of 125%, investors are becoming increasingly wary. The nonpartisan Congressional Budget Office projects this fiscal year's federal deficit will hit $2.1 trillion, about 6% of GDP.

US Treasury Secretary Bessent has been accused of leaning on gimmicks like bond buybacks to address the underlying debt problem, rather than a credible fiscal package. His former mentor, investing legend Stanley Druckenmiller, panned this approach, arguing that 'a credible fiscal package would do more for the long end of the curve than a buyback program a thousand times this size.'
