The US dollar held on to gains after the Federal Reserve’s hawkish surprise, keeping USD/JPY elevated and raising intervention risk. DXY pushed above 101.00 overnight and was set for its best week since April 2024, while markets continued to price a more aggressive Fed path, with 39bp currently priced in and scope for two hikes by December on a strong data print. Attention is shifting to Fedspeak and the extent to which FOMC members endorse the hawkish dot plot, a backdrop that could drive fresh repricing in rates and FX.
A US holiday is creating thinner liquidity, conditions in which Japan has previously opted to intervene in FX markets. USD/JPY has moved beyond the 2024 highs after breaking out yesterday, and the absence of official action would leave room for a push towards 162–163 in a supportive dollar environment.

Dollar Strength and Japanese Intervention Risk
The US dollar continues to show strength, pushing the USD/JPY exchange rate above 160.50, a level that has everyone on high alert. With today being a US holiday, the thinner market liquidity creates a classic window for Japanese authorities to step in. We are watching this situation very closely as it mirrors past intervention setups.
We see that interest rate markets are now pricing in a high probability of at least one more Fed rate hike by September, and possibly a second before year-end. This expectation of higher US rates is the main driver pulling money into the dollar. Any strong US economic data, like next week’s inflation report, could lock in these expectations and push the dollar even higher.
Volatility and Trading Strategy Implications
We must remember what happened in April and May of 2024 when the yen was pushed to similar levels near 160. Japanese authorities spent over $60 billion to support their currency, causing a sudden and sharp drop in USD/JPY. Given that history, the risk of a similar surprise move is extremely high right now.
For us, this environment screams high volatility, making it a difficult spot for simple directional bets. The implied volatility on one-month USD/JPY options has already jumped to over 11%, reflecting the market’s anxiety about a sudden move. This suggests that strategies that profit from large price swings, regardless of direction, could be more prudent than just buying or selling the currency pair outright.
However, if Japanese officials remain on the sidelines through this low-liquidity period, it could be seen as a green light for speculators. In that scenario, we believe the path of least resistance is up, with a test of the 162–163 levels becoming very likely. The market is caught between the powerful trend of a strong dollar and the powerful threat of intervention.
