The Hidden Risk in the US-Japan Yen Rescue
Aug 15, 2026 · 31m
Summary
Patrick Boyle analyzes Treasury Secretary Scott Bessent’s unprecedented intervention to support the Japanese yen, revealing it was funded by selling euros rather than dollars. This move aims to protect Bessent’s bet that US interest rates will fall, preventing Japan from selling US Treasuries and spiking American borrowing costs. Boyle critiques this "cakeism," arguing that US trade policies simultaneously weaken the yen, creating a contradictory trap where the US needs Japan to hold its debt while undermining the currency that facilitates those purchases.
