On April 30th, the Japanese yen experienced a sudden and unusual 3% rally against the U.S. dollar, marking its largest single-day move in over three years. This sharp reversal immediately sparked rumors of intervention by the Bank of Japan. In this breakdown, Jim Iuorio of TJM Institutional Services explores the mechanics behind this historic price action and what it means for retail currency traders.

Japan's central bank now faces a complex policy dilemma. This analysis provides the historical context and structural understanding needed to navigate ongoing volatility in the foreign exchange markets.
