Key Takeaways
- The dollar index surged past 101.00 to reach a 12-month peak following Federal Reserve indications of possible rate increases in 2026.
- Financial markets are now anticipating as many as two Fed rate hikes by year-end, strengthening dollar momentum.
- The yen collapsed to 161.82 per dollar, its weakest position in four decades, triggering speculation about Japanese government intervention.
- Geopolitical developments including a Middle East peace agreement and scrapped U.S.-Iran negotiations added volatility to dollar movements.
- Japan’s core inflation data showed a 1.4% yearly increase in May, remaining under the Bank of Japan’s 2% benchmark for four consecutive months.
The greenback surged to a 12-month high this week as market participants increasingly bet on Federal Reserve rate increases in 2026. The dollar index, measuring the U.S. currency against six major peers, momentarily exceeded 101.00 during overnight trading before retreating to approximately 100.78 on Friday amid reduced market activity due to the Juneteenth federal holiday.
The rally positions the dollar for its strongest weekly performance since 2024.
The catalyst emerged from updated rate forecasts published by Federal Reserve policymakers on Wednesday. Multiple officials now anticipate interest rate hikes during the current year. ING’s research team indicated that markets could completely factor in two rate increases by December following the next robust economic data release.
ING acknowledged that while they believe the probability of actual rate hikes is “overestimated,” the dollar could “enjoy post-Fed enthusiasm for a bit longer.”
Geopolitical Developments Create Dollar Volatility
A peace agreement reached this week in the Middle East eliminated a significant driver of dollar demand. The United States had attracted safe-haven flows during regional tensions, partially because American energy producers provided insulation from oil supply risks associated with the Strait of Hormuz.
Nevertheless, questions remain about the agreement’s longevity. Scheduled diplomatic discussions between Washington and Tehran in Switzerland were abruptly cancelled on Friday after Vice President JD Vance abandoned his planned Geneva visit. Switzerland’s foreign ministry acknowledged the postponement while expressing continued willingness to facilitate the negotiations focused on Iran’s nuclear activities.
MUFG Bank’s Derek Halpenny noted that the cancellation offered modest safe-haven support to the dollar, though the impact on risk sentiment appears limited and probably won’t disrupt the peace framework.
Yen Crashes to 1985 Levels
The most dramatic currency movement this week occurred in the Japanese yen. It plunged to 161.82 against the dollar, marking its weakest point in approximately four decades. The yen stabilized near 161.26 on Friday, though downward pressure persists.
Market participants are monitoring for potential intervention by Japanese officials to support the currency. Friday’s U.S. market closure created shallow liquidity conditions, which ING analysts highlighted as a period Japan has historically chosen for currency interventions.
“USD/JPY is already deep into intervention territory after breaking above the 2024 highs yesterday,” ING analysts stated. They cautioned that absent intervention, speculative forces might drive the exchange rate toward 162-163.
Japan’s Finance Ministry has previously intervened around the 160 threshold.
The Bank of Japan elevated interest rates to a 31-year peak this week, yet the policy adjustment has failed to bolster the yen. BOJ Deputy Governor Ryozo Himino highlighted uncertainties surrounding additional rate increases due to inflation concerns connected to Middle East tensions.
Official statistics released Friday revealed Japan’s core consumer price index climbed 1.4% annually in May, falling short of the BOJ’s 2% objective for a fourth consecutive month. Capital Economics analysts suggested the central bank might postpone its next rate increase beyond their current October projection.
The British pound advanced 0.3% versus the dollar to $1.3238, supported by domestic political developments following Greater Manchester Mayor Andy Burnham’s by-election victory, positioning him as a potential rival to Prime Minister Keir Starmer.
