The Bank of Japan just broke the mould. In a move that has sent shockwaves through global markets, the BoJ raised its benchmark interest rate to a 31-year high. This is not a gentle nudge. It is a sledgehammer aimed at inflation.
For decades, Japan has been the world’s laboratory for ultra-loose monetary policy. Negative rates, endless QE, yield curve control. It was a strange religion. The high priests at the BoJ kept the faith while the rest of the world tightened. Not anymore.
This is a political earthquake as much as an economic one. Prime Minister Kishida’s government has been walking a tightrope. Tame inflation was a gift to households still scarred by the Lost Decade. Now that gift has been snatched away. The cost of living crisis is real. And the BoJ has just made mortgage payments a lot more painful.
The timing is brutal. Kishida is already underwater in the polls. His approval rating is hovering around 30 per cent. The LDP’s backbenchers will be sharpening their knives. They know a rate hike means pain for their constituents. And they will demand answers.
But here’s the rub. The BoJ is independent. For now. The pressure from the LDP’s old guard to intervene will be intense. We have seen this movie before. In the 1990s, the Diet tried to bully the BoJ into easing. Now they will try to bully it into holding steady. Governor Ueda is not one for bowing. He is a professor, not a politician. But even professors have limits.
The market reaction was instant. The yen surged. The Nikkei tanked. Foreign investors who piled into the “carry trade” are now scrambling for cover. This is the end of cheap money in Tokyo. And it will ripple across Asia.
The real question is: can Japan’s economy absorb this? Wages are rising, but they lag inflation. Corporate profits are strong, but many firms are still fragile. And the government’s debt mountain is 260 per cent of GDP. Higher rates mean higher interest payments. That means less money for defence, for childcare, for everything Kishida promised.
Behind the scenes, the Treasury is panicking. The Ministry of Finance’s debt management division will be working overtime. They know that a sustained tightening could trigger a fiscal crisis. The bond markets are unforgiving. Just ask the UK.
What comes next? Expect a furious internal debate. The BoJ will argue that credibility demands continued normalisation. The politicians will argue that growth demands stability. The compromise, if there is one, will be a pause. A long one. But the genie is out of the bottle. Japan has crossed the Rubicon.
For the Westminster lobby, this is a warning shot. The Bank of England is watching closely. If the BoJ can break with its past, so can Threadneedle Street. But the politics of rate hikes are brutal. Ask Liz Truss. Ask Kwasi Kwarteng.
Today’s move is not just about Japan. It is about the end of a global era of cheap money. The party is over. The hangover is just beginning.
