USD/JPY remains firmly bid as yen weakness persists across the FX complex. Despite repeated warnings from Japanese officials, traders continue to push the pair higher, emboldened by the market’s track record of fading intervention rhetoric. With price action now hovering near the January 2025 high, attention is turning to whether yen bears can force a decisive break toward 160—or finally provoke a forceful response from Japan’s Ministry of Finance.

Yen Selling Accelerates as Risk-On Narrative Dominates
Taking a step back, it becomes clear just how aggressively traders have been shorting the Japanese yen against its peers. Despite 2025 initially shaping up as a bullish year on expectations of a more hawkish Bank of Japan, that narrative clearly failed to deliver. Instead, the yen topped out against all major FX peers back in April after President Trump significantly reduced tariffs, triggering a broad risk-on move across global markets.
Since then, the yen has effectively declined in a near-straight line against the euro, Swiss franc, British pound and Australian dollar. While occasional murmurs of intervention have surfaced along the way, markets have largely dismissed them.

That said, Japan’s newly appointed Finance Minister Satsuki Katayama has voiced concerns over the “one-sided depreciation of the yen,” adding that US Treasury Secretary Scott Bessent shares this view. This amounts to a deliberate warning aimed at entrenched yen bears, designed to revive fears of coordinated intervention between Japan and the US.
Markets Dismiss Intervention Rhetoric as USD/JPY Presses Higher
So far, it has failed to gain traction. USD/JPY continues to probe higher, flirting with a breakout above the January 2025 high.
That outcome is hardly surprising. Markets have a long history of ignoring verbal warnings, and if anything, yen traders tend to welcome the challenge—often daring Japan’s Ministry of Finance to follow through.
This USD/JPY chart highlights recent Ministry of Finance (MOF) intervention levels. The most notable episode occurred in 2024, when traders drove USD/JPY sharply higher—well beyond 155—before the MOF finally stepped in. A near-400-pip plunge followed, burning late yen sellers, but the impact proved short-lived. The pair soon stabilised and ultimately resumed its broader uptrend.
USD/JPY has since toyed with a breakout above the January 2025 high, though bulls have so far stopped short of a convincing break. Still, if history is any guide, it would not be surprising to see yen bears attempt to goad the MOF into action once again, potentially pushing USD/JPY above 159 in the near term. That said, trading against central banks carries added risk and can result in unfriendly bursts of volatility.

USD/JPY Technical Analysis: US Dollar vs Japanese Yen
At its current trajectory, USD/JPY could tag 160 as early as Thursday if yen bears get their way. The daily trend remains firmly bullish, with the 2025 high and the 159 handle the final technical hurdles—alongside the ever-present risk of Ministry of Finance (MOF) intervention.
An ascending triangle has formed on the 1-hour chart, and prices have already broken to the upside. Unless the MOF steps in, yen bears may attempt to goad authorities into action by buying dips, with a sustained break above 159 bringing 159.50 and 160 into view.
That said, any intervention would likely be swift and violent. A repeat of past episodes could see USD/JPY unwind by 300–400 pips in short order.
