- The USD/JPY exchange rate showed a significant rebound after closing in on the psychological barrier of 160. It once fell below the 158.5 level and touched around 158.34 on Wednesday, mainly driven by a marginal easing of geopolitical tensions and expectations of declining oil costs.
- The temporary two-week ceasefire agreement reached among the U.S., Iran, and Israel spurred expectations of reopening the Strait of Hormuz, which led to a sharp drop in West Texas Intermediate (WTI) crude oil prices by over 10% to around $90 per barrel, alleviating the trade deficit pressure for Japan, a net energy importer.
- The pricing probability in the interest rate derivatives market for the Bank of Japan (BOJ) to implement a rate hike this month has risen above 70%, with expectations for at least two more hikes by the end of the year. Meanwhile, the market is closely watching the forthcoming minutes of the Federal Reserve’s March meeting.
Declining Oil Costs and Current Account Repair
The phase-wise rebound of the Yen exchange rate profoundly reflects the underlying support of macro trade conditions for currency valuation. The Japanese economy heavily relies on external inputs of oil and natural gas. Previously, Middle Eastern geopolitical conflicts drove up oil prices, significantly increasing Japan's import bill and thereby leading to structural pressure on its current account deficit. With the two-week ceasefire and the anticipated reopening of the Strait of Hormuz, which accounts for nearly 20% of the global oil supply, WTI crude oil prices saw a single-day drop of over 10%, retreating to the $90 mark. This marginal easing of externally-imported inflation pressure directly reduced the demand for Japan's real economy to buy U.S. dollars to pay for energy imports. If oil prices can stabilize at current levels in the coming weeks, Japan's trade conditions are expected to substantively improve, thus providing fundamental liquidity support for the Yen exchange rate.
Central Bank Intervention Alert and Monetary Policy Pricing
While the external macro environment is showing signs of easing, the expectation management of Japan's domestic monetary policy is becoming another key variable driving the Yen's trend. Previously, the Yen's approach towards 160 against the dollar triggered intensive verbal intervention warnings from the Japanese Ministry of Finance and BOJ officials. Market traders had already accumulated considerable closing intentions near the intervention red line, and the ceasefire news served as a perfect catalyst. More critically, market bets on the BOJ's path to normalizing monetary policy are accelerating. Current overnight index swap (OIS) market pricing indicates a probability of over 70% for the BOJ to announce a rate hike at this month's meeting, with the forward curve factoring in expectations for at least two additional hikes before year-end. This macro narrative of a potentially gradually narrowing domestic and foreign interest rate differential prompts a significant amount of carry trade funds to begin profit-taking, further amplifying the Yen’s short-term upward elasticity.
Geopolitical Negotiation Window and Forward Exchange Rate Outlook
Despite multiple resonating favorable factors for the Yen in the short term, its structural weakness has not been fully reversed in a longer time frame. Over the past year, the Yen still recorded a decline of about 7.20% against the dollar. Analytical institutions maintain a relatively rational evaluation of the Yen's medium- to long-term trend, predicting that the exchange rate center will remain around 158.37 by the end of this quarter, with a forward outlook pointing to 154.42 a year from now. This gradual appreciation path suggests that the market believes the absolute interest rate differential between the U.S. and Japan will remain at a relatively high level for an extended time. Moreover, multilateral negotiations, scheduled to be held on April 10 in Islamabad involving complex geopolitical issues such as U.S. military withdrawal, and active diplomatic mediation by Japanese Prime Minister Sanae Takaichi, could influence the currency outlook. Should the two-week ceasefire fail to transform into a long-term peace agreement, the vulnerability of the energy supply chain may re-emerge, potentially posing a risk of a secondary bottoming in the Yen exchange rate.
