The Bank of Japan has finally done what many thought impossible: it has raised interest rates to levels not seen since 1995. The decision, which caught markets off guard, sends a clear signal that the era of ultra-loose monetary policy in Japan is over. For a country that has been the world's most aggressive monetary experimenter, this is a tectonic shift.
Governor Ueda's move to hike the benchmark rate to 0.5% might seem modest by historical standards, but it represents a doubling from the previous level and sets the stage for further tightening. The yen, which has been under relentless pressure against the dollar, surged in response. But the real story is what this means for global capital flows.
For years, investors have borrowed cheaply in yen to fund carry trades in higher-yielding assets elsewhere. Japan's rate rise threatens to unwind those positions, triggering a scramble for liquidity. The Nikkei 225 fell sharply as financial stocks led the decline, while bond yields in Tokyo spiked. This is not just a Japanese story. The ripple effects are already being felt in London and New York.
The FTSE 100 opened lower, with miners and insurers bearing the brunt. Gold prices slipped as the dollar weakened, but the real action is in the currency markets. The yen's strength could hit Japanese exporters like Toyota and Sony, which have benefited from a weak currency. Meanwhile, UK gilt yields rose as investors reassessed the global rate outlook.
The Bank of Japan's decision comes at a delicate time. Inflation in Japan has finally breached the 2% target on a sustained basis, but wage growth remains tepid. The risk is that higher rates choke off the fragile economic recovery. Yet the BOJ seems determined to normalise policy, even if it means breaking the global calm.
For the City of London, the immediate concern is the carry trade unwind. Hedge funds will be scrambling to cover short yen positions. This is a classic 'risk-off' event. The VIX, Wall Street's fear gauge, jumped 15% overnight. The Bank of England will be watching closely, but its own inflation problem means it cannot afford to cut rates anytime soon.
The bottom line: Japan has taken the first real step toward monetary normalisation since the 1990s. The markets are correct to be nervous. This is the beginning of a new chapter in global finance, and it will be messy.
