Two central banks are signaling tighter policy this week, and markets are watching both. The Bank of Japan's Summary of Opinions from the April meeting, which was released this morning, made clear that a rate hike as early as the June 16-17 meeting is genuinely on the table. One board member stated it is "quite possible that the bank will raise the policy interest rate from the next monetary policy meeting onward, even if the future course of the situation in the Middle East remains unclear." That means the BoJ is no longer willing to wait out the conflict, but might pre-emptively start raising rates.
The April meeting already told a hawkish story. The Bank of Japan held its short-term policy rate at 0.75% in a 6-3 vote, with three dissenters calling for an immediate hike to 1.0%. The central bank raised its FY2026 core inflation forecast to 2.8% from 1.9%, while trimming the growth outlook to 0.5% from 1.0%. Several members warned that second-round effects from elevated energy costs may force the bank's hand regardless of how geopolitics resolves, with one noting Japan's real policy rate is "by far the lowest globally."
Nikkei Holds Near Records
The Nikkei 225 gained around 0.52% on Tuesday to roughly 62,743, staying close to all-time high territory as technology shares extended their AI-driven rally. The index is navigating a delicate balance: a hawkish Bank of Japan would ordinarily weigh on equities, but the tech bid continues to absorb that pressure. Following the Summary of Opinions release, USD/JPY traded near 157.25, a level that reflects ongoing tension between a Bank of Japan edging toward tightening and a yen that has already strengthened materially from recent lows. Intervention risk remains live above 158.
CPI and the Fed Handover
On the U.S. side, the Senate voted 49-44 on Monday to approve Kevin Warsh's Federal Reserve nomination, with full confirmation expected this week ahead of Jerome Powell's term expiry on Friday. The Fed's first meeting under Warsh is scheduled for June 16-17, coinciding with the Bank of Japan’s next policy meeting.
Today's April Consumer Price Index release at 8:30 a.m. ET is the immediate catalyst. Headline CPI is expected at 0.6% month-over-month and 3.7% year-over-year, up from March's 3.3% annual rate, driven again by gas prices. Three FOMC dissenters at the April meeting already objected to keeping an easing bias in the statement, so a hotter-than-expected print today would strengthen their case further, thus making rate hikes more likely.
Oil remains the wild card. Iran's latest peace proposal was rejected by Trump as "totally unacceptable," and Brent continues to trade near $100. Until the Strait of Hormuz reopens in a sustained way, energy will keep acting as both an inflation accelerant and a growth headwind, a combination that has every major central bank cornered.
