The US Dollar (USD) swung between gains and losses on Wednesday, September 2, 2026, as traders weighed an uneasy mix of escalating US-Iran tensions, renewed speculation about Japanese currency intervention, and shifting bets on the Federal Reserve’s next policy move. The dollar index, which measures the greenback against a basket of six major currencies, ended the session little changed after a choppy day that saw it briefly touch a two-week high before paring gains.
Market attention now shifts to Thursday’s weekly initial jobless claims report and the Institute for Supply Management’s (ISM) Services PMI for August, both of which are expected to provide a clearer read on the health of the US economy. These data points come at a critical juncture, as the Fed’s next policy meeting is scheduled for later this month, and investors are increasingly split over whether the central bank will cut rates or hold steady.

Geopolitical Jitters and Intervention Risks Dominate Sentiment
The US-Iran crisis remained a key driver of currency flows, with any escalation in the Middle East prompting investors to seek the relative safety of the dollar. However, the greenback’s gains were capped by concerns that a prolonged conflict could disrupt global supply chains and weigh on US economic growth, complicating the Fed’s policy calculus.
Meanwhile, speculation over another bout of FX intervention by Japanese authorities kept the USD/JPY pair on edge. The yen has been under persistent pressure this year, and traders remain wary of sudden, large-scale dollar-selling by Tokyo, similar to the interventions seen in 2022 and again in 2024. Japan’s Ministry of Finance has repeatedly stated that it is watching currency moves with a “high sense of urgency,” but has declined to comment on specific intervention tactics.

“The market is walking a tightrope,” said a senior currency strategist at a European bank, speaking on condition of anonymity. “Geopolitical risk supports the dollar, but the threat of Japanese intervention and the growing likelihood of Fed rate cuts are pulling in the opposite direction. It’s a recipe for volatility.”
Fed Rate Cut Bets and the Looming Data Test
Fed funds futures now price in a roughly 60% probability of a 25-basis-point rate cut at the September meeting, according to CME Group’s FedWatch tool, down from nearly 75% a week ago. This shift follows a string of stronger-than-expected economic data, including a resilient labor market and firm consumer spending, which have led some policymakers to argue that the central bank can afford to be patient.
Thursday’s jobless claims data will offer the latest snapshot of the labor market. Economists expect initial claims to come in at around 230,000, little changed from the previous week, but any significant deviation could alter rate expectations. The ISM Services PMI, due later in the day, is forecast to show a modest slowdown to 52.5 from 53.1 in July, reflecting cooling but still positive activity in the dominant services sector.
The data will be scrutinized not just for the headline numbers, but for the underlying details, including employment, new orders, and prices paid sub-indexes. A strong reading could reinforce the case for the Fed to hold rates steady, while a weak one would likely bolster the case for a cut.
What to Watch Next
Beyond the immediate data releases, traders will be monitoring any new developments in the US-Iran situation and any verbal intervention from Japanese officials. The US Treasury Department’s semi-annual currency report, due later this month, could also be a flashpoint, particularly if it labels Japan or other trading partners as currency manipulators.
For dollar traders, the key takeaway is that the greenback is likely to remain at the mercy of crosscurrents. Geopolitical shocks could trigger sudden safe-haven flows, while central bank expectations and data surprises will drive the medium-term trend. As always, positioning and sentiment are fragile, and the potential for sharp reversals remains high.
Given the heightened uncertainty, market participants are advised to stay nimble and manage risk carefully. Currency markets are notoriously volatile, and this environment offers little room for complacency.
