Key Takeaways
- The US Dollar Index reached 101.25, marking its strongest performance in more than 12 months
- Market expectations now show an 80–85% probability of a Federal Reserve rate increase by autumn
- Japan’s currency is approaching its most vulnerable position since the mid-1980s, sparking intervention concerns
- British Prime Minister Keir Starmer’s resignation intensified selling pressure on the pound sterling
- The euro declined to multi-month lows following dovish commentary from ECB President Lagarde
Tuesday’s trading session witnessed the US dollar ascending to its strongest position in twelve months as market participants ramped up expectations that the Federal Reserve will implement an interest rate increase before year-end. The benchmark Dollar Index touched 101.25, representing its most elevated reading since May of the previous year.

Current Fed funds futures markets are indicating approximately an 80 to 85 percent likelihood of a 25 basis point rate adjustment occurring by September or October. Major financial institutions including BofA Global Research and Deutsche Bank have modified their previous projections, abandoning earlier predictions of unchanged monetary policy and now anticipating a rate hike within the coming months.
“Right now, the dollar is pricing in higher rates and is gaining on that,” said Tommy von Bromsen, FX strategist at Handelsbanken.
Persistent geopolitical instability stemming from unresolved Middle Eastern conflicts is providing additional tailwinds for dollar strength, von Bromsen noted.
Japanese Yen Teeters on Brink of Four-Decade Weakness
Japan’s currency finds itself in precarious territory. The yen momentarily touched 161.93 against the dollar during Monday’s session, and any movement beyond 161.96 would mark its feeblest position since 1986.
Traders remain vigilant for potential action from Japanese monetary authorities. Tokyo deployed several tens of billions of dollars during late April and early May attempting to support the yen, though these measures yielded only temporary results.
The Bank of Japan implemented an interest rate increase last week while communicating intentions for additional policy tightening moving forward. Despite these efforts, the yen has continued its descent, undermined by the substantial interest rate differential between the United States and Japan.
Japanese Finance Minister Satsuki Katayama engaged in discussions with US Treasury Secretary Scott Bessent on Monday. Their conversation centered on coordinated policy responses to address the yen’s depreciation, including the possibility of direct currency market intervention.
UK Political Upheaval Weighs on Sterling, Eurozone Weakness Persists
Sterling declined between 0.2 and 0.3 percent on Tuesday following UK Prime Minister Keir Starmer‘s resignation announcement, injecting political instability into British financial markets. Health Minister Wes Streeting expressed support for Andy Burnham as a potential successor, a development analysts suggest could minimize leadership transition uncertainty.
“With Streeting’s willingness to back Burnham, this uncertainty is now likely to be a thing of the past,” said Commerzbank FX analyst Michael Pfister.
The single European currency also experienced downward pressure, dropping to $1.1395, representing its weakest valuation since August of last year. ECB President Christine Lagarde offered reassuring remarks regarding secondary inflation effects on Monday, coinciding with data revealing the eurozone private sector contracted for a consecutive third month in June.
The Australian dollar weakened by 0.7 to 0.8 percent, reaching its lowest level since April.
Market participants are now directing attention toward forthcoming US economic releases. Wednesday’s May PCE price index data, which represents the Federal Reserve’s preferred inflation measurement, holds particular significance. June PMI figures and a revised first-quarter GDP estimate are also scheduled for release this week. These data points will likely determine whether the dollar’s upward momentum can continue.
