Japanese Yen Surges as MOF Steals the BOJ's Thunder After FOMC

By Matt Simpson | Thu, 30 Jul 2026

Overview

The Japanese yen experienced a significant rally following a suspected intervention by Japan's Ministry of Finance (MOF), leading to a sharp decline in the USD/JPY exchange rate. This event overshadowed the Bank of Japan's (BOJ) meeting, which was anticipated to provide further insights into Japan's monetary policy.

Suspected MOF Intervention

While official confirmation of the MOF's intervention is pending, the volatility observed in the currency markets suggests that intervention likely occurred. The USD/JPY pair fell nearly 600 pips, marking its largest one-day drop since April, and dipped below the 160 level before finding support above its 200-day exponential moving average (EMA).

Other currency pairs, such as EUR/JPY and AUD/JPY, also experienced significant declines, with EUR/JPY dropping 530 pips and AUD/JPY falling over 300 pips, indicating widespread strength in the yen against major currencies.

Focus on the BOJ Meeting

As the market shifts its attention to the BOJ meeting, expectations are that the central bank will maintain its current policy rate. However, any hints of a hawkish stance from Governor Ueda, such as improved growth or inflation forecasts, could further bolster the yen's momentum. Historically, volatility tends to decrease following intervention days, and while the BOJ meeting may add some excitement, significant price movements are not anticipated.

Extreme Yen Short Positioning

Recent data from the Commitment of Traders (COT) report indicates that traders were heavily short on the yen, with gross short positions among asset managers and speculators reaching near-record highs. This extreme positioning may have set the stage for a potential reversal in the yen's fortunes, as the market adjusts to the intervention news.

Technical Analysis of USD/JPY

Given the current market dynamics, establishing a directional bias for USD/JPY is challenging. Key support and resistance levels are identified, with 160 serving as a potential resistance point. The monthly pivot point is noted at 151.50, which will change after the month ends. The analysis suggests that while the yen has gained momentum, the volatility seen during the intervention may not be replicated in the immediate future.
