Japan’s financial markets entered a new phase of monetary pressure on Tuesday as the country’s 10-year government bond yield climbed to its highest level since 1997, while the yen extended losses against the dollar amid growing expectations that the Bank of Japan could raise interest rates again in the near term.

The yield on Japan’s 10-year government bond rose to around 2.55%, marking its highest level in nearly 29 years as markets increasingly priced in the possibility of another rate hike from the Bank of Japan as early as its next policy meeting.

The move followed the release of the central bank’s Summary of Opinions from its April meeting, which showed policymakers becoming increasingly concerned about rising inflation risks linked to elevated oil prices and ongoing geopolitical instability in the Middle East.

At its April 27 – 28 meeting, the Bank of Japan kept its benchmark interest rate unchanged at 0.75%, but raised inflation forecasts due to surging energy costs tied to the Iran conflict and disruptions surrounding the Strait of Hormuz.

Several policymakers indicated that additional tightening could begin soon.

One board member stated that there was “no need to take hasty action,” but argued the central bank should move toward higher rates unless clear signs of economic weakness emerge. Another member said it was “quite possible” that the BOJ could begin raising rates from the next meeting onward, while another warned policymakers may need to tighten “without hesitation” if upside inflation risks continue intensifying.

At the same time, some officials cautioned that Japan’s economy still faces downside risks from higher energy costs and weaker domestic demand, even as the country continues recovering at a moderate pace.

Yen Weakens as Dollar Strengthens

Meanwhile, the Japanese yen weakened to around 157.5 per dollar, extending losses for a second straight session as the US dollar strengthened globally following renewed uncertainty surrounding the durability of the US-Iran ceasefire.

President Donald Trump questioned whether the ceasefire would hold after rejecting Tehran’s latest response to a US peace proposal, keeping inflation and energy market concerns elevated across global financial markets.

Japan and the United States also reaffirmed close coordination on currency policy after Japanese Finance Minister Satsuki Katayama met with US Treasury Secretary Scott Bessent.

Market estimates suggest Tokyo may have spent more than $63 billion intervening in currency markets to support the yen, although Japanese authorities have not officially confirmed those operations.

Key Japan Market Indicators

EcoPulse24 Analysis

The latest moves across Japan’s bond and currency markets highlight a major turning point for the world’s third-largest economy after decades of ultra-low interest rates and aggressive monetary accommodation.

What makes the current environment particularly significant is that inflationary pressure is no longer being driven primarily by domestic demand, but increasingly by imported energy costs and global geopolitical shocks.

Japan remains highly dependent on imported energy, meaning elevated oil prices linked to Gulf tensions are feeding directly into transportation, production and consumer costs across the economy.

At the same time, the weakening yen is amplifying inflationary pressure by making imports even more expensive for households and businesses.

That leaves the Bank of Japan facing one of its most difficult policy balancing acts in years.

Raising interest rates may help stabilize inflation expectations and support the yen, but it also risks slowing an economy that still faces structural growth challenges and fragile domestic consumption.

The situation is further complicated by Japan’s massive public debt burden, one of the highest among advanced economies, making sustained increases in bond yields financially sensitive for the government and broader financial system.

The sharp rise in long-term yields also signals that global investors are beginning to seriously reprice the future path of Japanese monetary policy after years of assuming near-zero rates would remain permanent.

In many ways, markets are now starting to price the end of Japan’s ultra-cheap money era.

And if oil prices remain elevated through the second half of 2026, Japan could increasingly face a difficult combination of slowing growth, imported inflation and currency weakness - an economic environment the country has largely avoided for decades.
