**Deck**: The Bank of Japan has raised interest rates to their highest level since 1995 while warning that surging energy costs are feeding into consumer prices faster than expected, threatening to push inflation above target. The move squeezes heavily indebted sectors at home and could rattle global bond markets that have grown used to Japan as a source of cheap capital.

Japan has just taken its most forceful step in a generation to stop inflation from getting away, and in doing so it may have jolted the global financial system that has long relied on its ultra-cheap money. The Bank of Japan lifted its policy rate to the highest level since 1995 as the yen languishes near historic lows, and warned that rising energy costs are filtering into consumer prices more quickly than before, raising the risk that inflation will exceed its target.

For Japanese households, the central bank’s warning is a recognition of something already felt in supermarket aisles and utility bills. A weaker yen has made imported fuel and food more expensive, and the BOJ now concedes that energy costs are feeding through faster into what families pay. A rate hike is designed to defend the currency and anchor expectations, but it also raises borrowing costs for mortgages, small businesses and local governments still recovering from years of stagnation and the shock of the pandemic.

The BOJ’s move marks a sharp turn from its long-standing role as the outlier among major central banks, maintaining near-zero or negative rates even as the Federal Reserve and European Central Bank tightened. By raising rates to a 31‑year high, Tokyo is signaling that the risk of entrenching inflation now outweighs its fear of undermining growth. That recalibration comes as Japan faces demographic decline, a heavy public debt load and a corporate sector accustomed to ultra-low funding costs.

Globally, the change matters because Japanese investors are major holders of foreign government bonds and corporate debt. Higher yields at home can pull some of that capital back, putting upward pressure on borrowing costs for other countries and companies. If the BOJ is forced into further tightening to support the yen or tame energy-driven inflation, the ripple effects could be felt in U.S. Treasuries, European sovereign debt and emerging-market bonds that have counted on steady Japanese demand.

Energy markets are an unspoken driver of this shift. As the BOJ itself notes, rising energy costs are no longer a peripheral factor but a central channel pushing up prices at the consumer level. Japan is a major importer of liquefied natural gas and oil, and any renewed disruption in key maritime routes—from the Strait of Hormuz to the South China Sea—can quickly transmit into Japanese inflation data. In that sense, the BOJ is being forced to price in geopolitical risk as much as domestic wage dynamics.

The stakes for policy credibility are high. After years of attempting to generate modest inflation to escape deflationary psychology, the BOJ now has to convince markets and citizens that it can stop prices from overshooting without choking off the fragile wage gains it has encouraged. If it moves too slowly, the yen could fall further and energy inflation could become entrenched; if it moves too fast, it risks destabilizing banks, insurers and pension funds loaded with low-yielding assets.

A useful way to see this moment is as a stress test of how much geopolitical and energy shock a heavily indebted, aging economy can absorb before its central bank is forced into a new regime. Japan’s rate hike is not just a domestic monetary adjustment; it is a signal that the era of costless money from one of the world’s largest creditors is under strain.

Investors and policymakers will be watching the yen’s response in the days ahead, any signs of stress in Japan’s bond market, and whether the BOJ’s inflation forecasts are revised further upward in light of energy trends. Moves by Japanese institutions to rebalance portfolios away from foreign assets, or by the government to cushion households from higher rates and energy bills, will indicate how much pressure this historic shift is putting on both Japan’s economy and the wider financial system.
