The Bank of Japan has done what many thought impossible: it has raised interest rates to a level not seen since the early 1990s, sending a jolt through global financial markets that will be felt for weeks. The move, taking the benchmark rate to 2.5 per cent, is a stark departure from the ultra-loose monetary policy that has defined Japan’s economy for decades. And it is a reminder that the era of cheap money may finally be over, even in the world’s most stubborn deflationary outlier.
For years, Japan has been the global market’s comfortable crutch. Its negative interest rates and yield curve control allowed investors to borrow cheaply in yen to fund carry trades into higher-yielding assets elsewhere. That era is now in the rearview mirror. The immediate reaction was predictable: the yen surged, the Nikkei tumbled, and bond yields spiked. But the ripple effects go much deeper.
This is not just a Japanese story. It is a story about the end of a global liquidity party. Japan was the last major holdout of ultra-easy policy. The Bank of Japan has now joined the Federal Reserve and the Bank of England in the tightening camp. The difference is that Japan’s move is arguably more jarring because it comes after decades of stagnation. The message is clear: even the most dovish central bank in the world is now focused on fighting inflation.
Let us not kid ourselves. This is a crisis of confidence. The markets had been pricing in a gradual normalisation, not a sudden lurch to a 31-year high. The BOJ’s move is a bet that the Japanese economy can withstand higher borrowing costs. But the data is mixed. Wage growth is picking up, but consumption remains fragile. The property market is showing signs of strain. And the government’s debt-to-GDP ratio is over 250 per cent. Higher rates mean higher interest payments for a government that relies on the central bank to keep its borrowing costs low. That is a fiscal tightrope.
The global implications are significant. Japanese investors are among the largest holders of foreign bonds, particularly US Treasuries. With yields at home now more attractive, we could see a repatriation of capital. That would put upward pressure on the yen and downward pressure on foreign bond prices. The carry trade, which has been a staple for hedge funds, is now facing a margin call of epic proportions. The unwinding could be violent.
But let us be clear: this is not a disaster for everyone. For the Japanese saver, long starved of any return on cash, this is a welcome change. For the yen, which has been chronically undervalued, this is a chance to regain some dignity. And for global central banks, it is a validation that the fight against inflation is not over. The BOJ has essentially told the world: we are serious about price stability. That is a good thing in the long run, but the short-term pain is real.
I cannot help but feel a sense of schadenfreude watching the pundits scramble to explain why this was inevitable. They have been saying that Japan would never normalise for years. Yet here we are. The lesson is simple: in markets, never say never. The BOJ has shattered a consensus that was too comfortable. The question now is whether the economy can bear the weight of higher rates. If it can, this will be seen as a bold act of monetary discipline. If it cannot, we are in for a messy period of Japanese recession and global volatility.
For investors, the message is to tighten your seatbelts. The days of easy money from Japan are over. The carry trade is dying. Bond markets are repricing. And the yen is finding its spine. This is not a time for complacency. It is a time for hard-nosed analysis and a healthy dose of scepticism. The BOJ has lit a fire. We will see who gets burned.
