Key Moments
- USD/JPY trades around 157.70, extending a three-day winning streak during Asian hours on Wednesday.
- Japan’s current account surplus rose to JPY 4,681.5 billion in March, beating expectations of JPY 3,879 billion and marking a record high.
- April US CPI increased 0.6% month-over-month, lifting the annual rate to 3.8% and reinforcing expectations of higher-for-longer Fed policy rates.
Yen Weak Despite Record Current Account Surplus
USD/JPY continues to grind higher for a third consecutive session, with the pair trading near 157.70 during Asian trading on Wednesday. The move reflects persistent weakness in the Japanese Yen (JPY), even after Japan reported a substantial improvement in its external balance.
Japan’s current account surplus climbed to JPY 4,681.5 billion in March, up from JPY 3,625.3 billion in the same month a year earlier. The outcome exceeded market forecasts of JPY 3,879 billion and represented the largest surplus on record. Despite this supportive fundamental data, the Yen remains under pressure against the US Dollar (USD).
BoJ Policy Outlook: Hawkish Signals Emerge
The Bank of Japan’s April Summary of Opinions indicated that officials are weighing the possibility of additional interest rate increases as early as their next policy meeting. The discussion is driven in large part by inflation risks associated with rising oil prices.
Alongside the BoJ’s own deliberations, the Organisation for Economic Co-operation and Development (OECD) outlined recommendations for Japan’s fiscal and monetary framework. The OECD suggested that Japan should mainly rely on consumption tax hikes to strengthen government revenue. On interest rate policy, it projected that the Bank of Japan would lift short-term policy rates to 2% by the end of 2027, while maintaining enough flexibility to adjust the pace and maturity profile of its bond purchases if strains emerge in financial or bond markets.
The OECD also called for tighter fiscal discipline, advising that the government restrict the use of supplementary budgets to periods of major economic shocks.
OECD Guidance and BoJ Policy Path
| Institution | Key Recommendation / Projection |
|---|---|
| OECD | Rely primarily on consumption tax increases to boost national revenue. |
| OECD | Short-term policy rates to reach 2% by end-2027, with flexible bond-buying pace and maturities. |
| OECD | Limit supplementary budgets to episodes of significant economic shocks. |
Geopolitics and Middle East Tensions Bolster the Dollar
The Dollar’s strength against the Yen is also underpinned by heightened geopolitical uncertainty in the Middle East. The Greenback has found support after recent remarks by US President Donald Trump on Iran. While he stated that Iran is “under control,” he cautioned that the situation could lead to either a new agreement or complete “decimation.”
In turn, Iranian Deputy Foreign Minister Kazem Gharibabadi responded with firm conditions for any settlement, insisting that a viable peace arrangement must provide reparations, acknowledge sovereignty over the Strait of Hormuz, and bring an end to US sanctions.
US Inflation Data Reinforces Hawkish Fed Expectations
Additional support for the USD stems from stronger-than-anticipated US inflation figures, which have strengthened expectations that the Federal Reserve (Fed) will keep interest rates elevated to manage ongoing price pressures.
The Bureau of Labor Statistics reported on Tuesday that the US Consumer Price Index (CPI) for April increased 0.6% on a month-over-month basis. This pushed the year-over-year inflation rate to 3.8%, the highest level since May 2023. Core CPI, which excludes food and energy components, also moved higher, registering a 2.8% annual gain.
Understanding the Japanese Yen: Key Drivers
The Japanese Yen (JPY) ranks among the most actively traded currencies globally. Its valuation is broadly influenced by the trajectory of Japan’s economy, with particular emphasis on the Bank of Japan’s policy stance, interest rate differentials between Japanese and US government bonds, and overall risk sentiment in global markets, among other factors.
Impact of Bank of Japan Decisions on JPY
One of the Bank of Japan’s mandates is currency control, which makes its policy decisions critical for the Yen. The central bank has at times intervened directly in foreign exchange markets, typically to weaken the Yen, although such operations are infrequent due to political sensitivities with major trading partners.
The BoJ’s ultra-loose monetary policy from 2013 to 2024 contributed to a broad depreciation of the Yen versus other major currencies, reflecting a widening policy gap between the BoJ and other leading central banks. More recently, the gradual reversal of this ultra-accommodative stance has provided some support for the Japanese currency.
Yield Differentials and Risk Sentiment
Over the past decade, the BoJ’s commitment to ultra-loose policy has contrasted sharply with the more restrictive posture of other central banks, especially the US Federal Reserve. This divergence widened the spread between 10-year US and Japanese government bond yields, favoring the US Dollar over the Yen. In 2024, however, the BoJ’s move to step back from ultra-loose policy, together with rate cuts by other major central banks, has begun to narrow this yield gap.
The Yen is also widely viewed as a safe-haven asset. During episodes of market turbulence, investors often seek the Japanese currency for its perceived stability and reliability. Periods of elevated stress therefore tend to support the Yen against currencies considered to carry higher risk.
