USD/JPY Correlation Hinges on US Yield Curve Amid Bessent's Fiscal Plan

The Japanese yen has seen a rare win against the US dollar over the past week, thanks to factors that have historically weakened it. The main culprit behind this shift is the widening yield differentials between the two countries' long-dated bonds.

The relationship between yield spreads and USD/JPY remains dominant, with any significant changes in US borrowing costs having a substantial impact on the currency pair. This week, the focus will be on how US Treasury Secretary Scott Bessent's efforts to limit the rise in long-term bond yields affect the market.

Bessent has promised to release a fiscal consolidation plan before Tuesday, but its credibility is uncertain given the administration's history of stimulative fiscal policy. The US public debt has surpassed $40 trillion for the first time, and large deficits remain entrenched.
