The Japanese yen climbed against the US dollar in Asian trade on Tuesday, supported by falling oil prices and reduced fears of stagflation in Japan. The dollar/yen pair traded near 159.00, as traders scaled back expectations for a faster tightening cycle by the Bank of Japan.
Lower oil prices reduce stagflation risk
West Texas Intermediate crude futures dropped 2.5% to $82.50 a barrel, easing Japan’s import bill and taking pressure off the Bank of Japan to push through an aggressive series of rate hikes.
The softer energy backdrop helped calm concerns that Japan could face a mix of weak growth and high imported inflation. With that risk receding, policymakers gain more room to prioritize supporting growth rather than reacting to cost-push price spikes through higher borrowing costs. This stronger fundamental footing is seen as backing the yen’s value beyond near-term rate differentials.
BoJ, Middle East risks still in focus
Bank of Japan Governor Kazuo Ueda cautioned on Monday that renewed tensions in the Middle East could still threaten Japan’s outlook if energy prices rebound. His remarks followed recent swings in crude prices that had briefly fuelled expectations of an earlier rate increase in Japan.
Despite the latest pullback in oil, Ueda’s comments signaled that the central bank remains alert to external shocks that could quickly re-ignite imported inflation pressures.
Diplomacy talk cools safe-haven dollar demand
The yen also gained as reports indicated the United States and Iran may extend their current two-week truce into a broader agreement aimed at reducing regional conflict. The prospect of diplomatic progress eased demand for traditional safe-haven assets, including the US dollar.
President Donald Trump later said Iran had reached out to resume wider negotiations, while Vice President J. D. Vance described recent exchanges as constructive and potentially opening the door to further de-escalation. The tone from Washington helped stabilize risk sentiment and undercut the dollar’s recent strength.
Fed signals measured stance on inflation and rates
Federal Reserve Governor Miran said ongoing energy disruptions have not yet altered long-term inflation projections and reiterated an expectation that inflation will return to target within a year. The comments suggested a cautious, rather than urgent, approach to any further rate moves.
Separately, US Treasury Secretary Bessent urged patience before cutting interest rates, expressing confidence that recent price gains will not become entrenched. Markets read her remarks as pointing to a steady and measured trajectory for US monetary policy.
As a result, futures markets now see less than a 30% chance of a Fed rate hike by the July meeting, sharply down from about 65% a week earlier. The reduced probability of higher US yields has weakened the appeal of holding dollar-denominated assets and narrowed the yield advantage that had supported the greenback.
Positioning and flows add to yen’s upside risk
Data from the Commodity Futures Trading Commission released on Friday showed speculative net short positions in the yen remain near multi-year highs, at more than 120,000 contracts. Such heavy one-sided positioning leaves the market vulnerable: further yen strength could trigger a rapid short-covering wave as traders buy back the currency to close bearish bets, potentially accelerating a drop in the dollar/yen rate.
At the same time, the combination of diplomatic progress and a more patient Fed is encouraging capital to rotate away from the safety of the dollar. Flows are starting to seek higher returns in areas that benefit from global stability and softer rate expectations. Select international equities and technology indices drew about $4.2 billion in inflows over the past five sessions.
Key technical level in focus
Market participants are now watching the 158.50 level in dollar/yen. A sustained break below that area would be seen as signaling a more decisive reversal of the previous uptrend in the pair.
