The Japanese yen hovered near the closely watched 160-per-dollar level on Friday, keeping traders on alert for possible intervention, while the U.S. dollar strengthened on safe-haven demand fueled by escalating tensions in the Gulf region.
The yen traded around 159.93 per dollar, just below the threshold that has previously triggered official market action, as Japanese authorities issued renewed warnings against excessive currency volatility.
Japan’s Finance Minister Satsuki Katayama said authorities stood ready to respond at any time and reserved the option of taking “decisive action” if market movements became disorderly.
The yen has now fallen for four consecutive weeks against the dollar, reversing earlier gains driven by intervention-like buying, as investors continue to bet on persistent interest rate differentials between Japan and the United States.
Intervention risk rises
Market participants say the 160 level remains a critical psychological and policy threshold, after previous episodes in which Japanese authorities intervened to support the currency.

Despite official warnings, speculative positioning against the yen remains elevated, with traders holding one of the largest bearish positions since mid-2024, according to market data cited by analysts.
Economists argue that without a meaningful shift in Japan’s monetary policy outlook, downward pressure on the yen is likely to persist.
The Bank of Japan is widely expected to consider further interest rate adjustments later this year, as higher import costs—particularly energy—add to inflationary pressures.

Dollar gains on geopolitical risk
The U.S. dollar has been the main beneficiary of recent market volatility, gaining broadly against major currencies as investors seek safety amid renewed tensions in the Gulf and uncertainty over global growth.
Geopolitical instability has pushed oil prices above US$90 per barrel, reinforcing concerns about inflationary pressures for energy-importing economies such as Japan, the euro zone and parts of Asia.
Safe-haven demand has also been supported by stronger-than-expected U.S. economic data, which have reinforced expectations that interest rates will remain elevated for longer.
U.S. data and rate expectations
Recent data on employment, consumer spending and business activity have surprised to the upside, strengthening what analysts describe as the “American exceptionalism” narrative in financial markets.
U.S. Treasury yields have risen sharply in recent weeks, widening interest rate differentials in favour of the dollar and attracting capital inflows.
Traders are now awaiting U.S. nonfarm payrolls data, which is expected to show a modest job increase in May, with unemployment projected to remain steady.

Broader currency pressure
The euro and sterling also traded under pressure over the past month, although both recovered slightly on Friday. Analysts say elevated energy prices remain a key drag on European economic activity and currency performance.
Market strategists warn that continued geopolitical uncertainty in the Middle East could sustain dollar strength in the near term, particularly if oil prices remain elevated and global growth expectations soften.
For Japan, however, the immediate focus remains the yen’s proximity to intervention territory, with traders closely watching whether authorities will act to stabilise the currency or allow further depreciation in line with monetary policy divergence.
