Past interventions, including the 1985 Plaza Accord and the 1998 response to the Asian Financial Crisis, stabilized the yen, weakened the dollar, and propelled global assets higher. Analysts now caution that a coordinated intervention could yield results similar to those seen in 2008, creating a significant liquidity boost for global markets. The Fed is intervening to save the yen, CFA Michael Gayed noted, highlighting that a Japanese-only intervention could force the Bank of Japan to sell US Treasuries to acquire dollars, potentially destabilizing global debt markets.

However, markets could face turbulence as traders adjust to sudden yen strength. Therefore, the setup is both risky and historically bullish for investors. If the Fed and Japan act in concert, the move could trigger a broad market rally. Such an outcome would provide long-term upside for equities, commodities, and digital assets. However, short-term adjustments and liquidation pressures could create temporary pain, particularly for leveraged positions in yen-funded trades. It explains why traders and policymakers alike are watching the yen, because the outcome could go beyond determining the trajectory of the dollar and yen. Rather, it could also set the stage for one of the most consequential macro setups of the year. Read the article at BeInCrypto
