The U.S. dollar advanced across major currencies during Asian trading on Friday, reaching its strongest level in a year as investors reacted to growing uncertainty surrounding a fragile peace agreement between the United States and Iran. At the same time, the Japanese yen remained under intense pressure, hovering near multi-decade lows despite recent efforts by Japanese authorities to support the currency.
Market sentiment shifted after reports that U.S. Vice President JD Vance had withdrawn from a planned diplomatic visit to Switzerland, where American and Iranian officials were expected to begin detailed discussions on implementing a 14-point agreement designed to end months of conflict between the two nations. The development raised fresh doubts about the durability of the peace framework and prompted investors to seek safety in the U.S. dollar.
As a result, the U.S. Dollar Index, which tracks the greenback against a basket of six major currencies, rose 0.3% to 101.07, marking its highest level in a year. The stronger dollar reflected investor caution as geopolitical uncertainty resurfaced in the Middle East, a region that continues to play a crucial role in global energy markets and broader economic stability.
The Japanese yen initially showed signs of strength during the trading session but later surrendered those gains and traded nearly unchanged at 161.455 per dollar. The currency remains close to levels that have triggered government intervention in the past and is approaching its weakest point in decades. Trading activity was relatively subdued due to public holidays across several Asian financial centers, including China, Hong Kong, and Taiwan, while the approaching U.S. holiday also reduced market liquidity.
Analysts noted that financial markets will be closely monitoring the next phase of negotiations between Washington and Tehran. While the preliminary agreement offered hope for stability, investors remain uncertain about how effectively both sides can implement the deal and navigate potentially difficult follow-up negotiations in the coming weeks.
The British pound also weakened against the dollar, slipping 0.2% to $1.3174. The currency’s decline largely mirrored broader weakness among major currencies as investors gravitated toward the U.S. dollar. Political developments in the United Kingdom attracted attention after Greater Manchester Mayor Andy Burnham secured victory in a by-election in Makerfield, strengthening speculation that he could eventually challenge Prime Minister Keir Starmer for leadership of the governing Labour Party.
Meanwhile, the Japanese yen continued to struggle despite several supportive measures introduced by policymakers. Earlier this year, Japan’s Ministry of Finance intervened directly in currency markets by selling dollars and buying yen. More recently, the Bank of Japan raised interest rates to their highest level in 31 years in an effort to strengthen the currency and address inflation concerns. However, these actions have delivered only limited results.
Investor confidence has also been affected by concerns over the fiscal spending plans of Prime Minister Sanae Takaichi. Market participants worry that increased government spending could place additional pressure on Japan’s finances and complicate efforts to stabilize the currency. As a result, speculation is growing that authorities may once again intervene in foreign exchange markets if the yen continues to weaken.
Currency strategists point out that speculative bets against the yen remain elevated despite the Bank of Japan’s latest rate increase. This suggests that many investors remain unconvinced that current policy measures will be enough to reverse the currency’s long-term decline.
Analysts believe Japanese policymakers are approaching the limits of their tolerance for further yen depreciation. In addition to direct intervention, officials may intensify verbal warnings to currency traders in an effort to discourage excessive speculation. Falling oil prices could also provide some support for Japan’s currency by reducing the country’s import costs and easing pressure on its trade balance.
Economic data released on Friday showed that Japan’s annual core inflation rate remained below the Bank of Japan’s 2% target for a fourth consecutive month in May. Government fuel subsidies helped offset rising costs associated with higher raw material prices stemming from tensions in the Middle East. While inflation has moderated for now, economists expect price pressures to build again over the coming years as energy costs gradually filter through to utility bills and consumer goods.
Several economists forecast that inflation could accelerate toward 3.5% by early 2027 as businesses pass higher operating expenses on to consumers. Such a scenario could force the Bank of Japan to consider additional interest rate increases, especially if inflation becomes more widespread across the economy.
Further insight into policymakers’ thinking emerged through minutes from the Bank of Japan’s April meeting and comments from Deputy Governor Ryozo Himino. Both suggested that additional rate hikes remain possible if inflationary pressures linked to the Middle East conflict intensify and threaten price stability.
Market participants are also watching key technical levels for the yen. Analysts believe Japanese authorities may aggressively defend the currency if it approaches 161.95 per dollar. Previous interventions in April and May involved trillions of yen and temporarily slowed the currency’s decline. However, repeated interventions come at a significant cost and could eventually reduce the government’s flexibility if market pressures persist.
Experts estimate that Japan has already committed substantial financial resources to defending its currency this year. While these efforts have helped slow volatility, they have not fundamentally changed the market forces driving yen weakness. As a result, policymakers may need to become increasingly selective about when and how they intervene going forward.
The dollar’s broader strength this week has also been fueled by changing expectations surrounding U.S. monetary policy. Investors are reassessing the possibility that the Federal Reserve may need to tighten policy sooner than previously expected in order to contain inflationary risks. Those expectations have boosted demand for the dollar and increased pressure on rival currencies.
According to market pricing, traders now see a significantly higher probability that the Federal Reserve could raise interest rates by 25 basis points at its July meeting. Expectations for such a move have climbed sharply over the past week, reflecting growing concern that inflation may remain more persistent than previously anticipated.
Elsewhere in currency markets, the euro declined 0.3% to $1.1419, while the Australian dollar slipped 0.3% to $0.6994. New Zealand’s currency also weakened, falling 0.5% to $0.5726 as the stronger U.S. dollar dominated trading activity.
Cryptocurrency markets also experienced modest losses. Bitcoin fell 0.7% to $62,549.31, while Ether declined 0.9% to $1,693.19 as investors adopted a more cautious stance amid geopolitical uncertainty and shifting expectations for global interest rates.
With uncertainty surrounding U.S.-Iran diplomacy, expectations for Federal Reserve policy, and persistent weakness in the Japanese yen, financial markets are likely to remain highly sensitive to political and economic developments in the days ahead. Investors will be closely watching whether the peace agreement progresses as planned and whether Japanese authorities take additional steps to stabilize their currency.
