Yen Reversal Threatens Global Markets

Japan's efforts to stabilize its currency have drawn attention from global markets. The yen has been weakening for years, despite repeated interventions by the Bank of Japan (BOJ). In recent months, the Japanese government and central bank have joined forces with the US Federal Reserve to prop up the currency.

The BOJ's 1% policy rate is well below the Fed's 3.5-3.75% range, creating a sharp interest-rate differential between the two countries. This has made dollar assets more attractive, putting additional pressure on the yen. Furthermore, Japan relies heavily on imported fuel, which has become more expensive due to the Iran conflict.

The combination of these factors has created a persistent flow of yen sales into dollars and other currencies. The weaker exchange rate raises the domestic cost of imports, reinforcing inflationary pressures facing Japanese households. To address this issue, the government approved a $135 billion stimulus package that included energy subsidies.
