📝 Executive Summary
The Japanese yen continues its relentless decline against the dollar, plumbing multi-decade depths as the Bank of Japan’s ultra-loose monetary stance widens the interest rate gap with the Federal Reserve. Carry trades and speculative shorts amplify the rout, prompting escalating verbal warnings from Tokyo. Officials have not ruled out direct intervention, but market participants and past episodes suggest such moves are unlikely to reverse the bearish trend without a fundamental shift in yield differentials. The real effective exchange rate underscores the yen’s historic undervaluation, lifting exporter profits while squeezing domestic purchasing power.
