Japanese Yen Outlook: Are USD/JPY Bulls Right to Ignore MOF Intervention Risk?

USD/JPY has surged to fresh highs following the latest FOMC meeting, supported by rising US yields, a stronger US dollar and record short positioning against the Japanese yen. Yet with the pair trading around previous intervention levels, traders face a key question: is Japan's Ministry of Finance willing to intervene again, or will it allow market forces to dictate the next move?

Record Yen Shorts Signal Confidence in Higher USD/JPY

A hawkish Fed was the icing on the cake for a higher USD/JPY following the latest FOMC meeting. Yields rose alongside the US Dollar Index, which now proudly sits at a 14-month high and just above my 100.50 target. Futures traders were already positioned for a higher USD/JPY, with their gross short exposure to the Japanese yen reaching a record high last week, according to the latest Commitment of Traders (COT) report.

Not only does this reflect confidence in a weaker yen, but it also suggests a complete disregard for the risk of another round of intervention from the Ministry of Finance (MOF). But are these traders right to be so confidently complacent? Possibly.

Why Yen Intervention May Be Less Effective This Time

The MOF will be weighing up whether it wants to swim against the tide. Intervention is not cheap, and any action could have a limited impact if it fails to convince USD/JPY bulls that authorities have the firepower to alter the trend of a rising US dollar backed by supportive fundamentals. It is also worth noting that USD/JPY is the only major yen pair to have broken to fresh highs among the FX majors. Perhaps this allows the MOF to save face temporarily, but if we see the likes of the British pound, euro, Swiss franc and other major currencies also break to new highs, it puts Japan’s authorities in a very tight spot.

Why USD/JPY Pullbacks May Be Short-Lived

For now, I suspect the MOF will stand pat and rely on verbal warnings. That leaves USD/JPY vulnerable to its own market forces as weaker hands are flushed out during bouts of headline-driven volatility or profit-taking. The risk of such a pullback appears elevated heading into the weekend, with USD/JPY trading just beneath its 2024 intervention high.

But unless the MOF feels the need to fight the bullish tide in USD/JPY, pullbacks are likely to be shallow and short-lived.

What History Tells Us About Yen Intervention

A quick review of previous intervention episodes shows that MOF action has generally coincided with major tops in USD/JPY. We can see two broad outcomes: either intervention marks a prominent peak and USD/JPY declines for several months, or it merely acts as a bump in the road before the uptrend resumes.

The April 2024 intervention initially triggered a sharp one-week decline of 5.1%, but the selloff soon faded. A second, more successful intervention followed, helping drive a broader 13.8% decline over the subsequent months. Price action this time around bears some resemblance to that period.

However, the backdrop is arguably less favourable for intervention today. The MOF is facing a hawkish Fed, elevated US yields and resilient US economic data. As a result, USD/JPY bulls may be more willing to buy dips, whether they are driven by natural market forces or another round of verbal intervention.

USD/JPY Technical Analysis: US Dollar vs Japanese Yen

The bullish breakout on Thursday is hard to ignore, given it produced the widest daily range for USD/JPY in six weeks. However, the high stalled just a few pips above the 2024 intervention level and just shy of the 2024 high. The MOF may not need to do much for market participants to second-guess the rally heading into the weekend, prompting bulls to take profits or encouraging countertrend traders to take a punt. I therefore suspect USD/JPY will be vulnerable to sharp whipsaws around current levels, and I would treat any break above the 2024 high with caution.

Remember, it costs nothing to jawbone a currency. And a break above the 2024 high would surely invite a stronger response from the MOF.

The 1-hour chart already suggests nerves are creeping in, with a high-volume bearish outside candle emerging despite finding support at the daily VWAP and leaving a lower wick. Regardless of whether the MOF becomes vocal, volatility could remain elevated into the end of the week. Yet any meaningful dips may still be viewed favourably by USD/JPY bulls heading into next week.

For now, the market appears comfortable fading intervention risk, but a break above the 2024 high may be enough to test that conviction.
