The Bank of Japan Makes a Historic Move: What It Means For You

For most of the past three decades, Japan has been the world's most famous example of ultra-low interest rates. Rates were effectively zero or even negative, as the country battled deflation and sluggish growth.

This week, that changed.

The Bank of Japan raised its policy rate to 1% on Tuesday, the highest level since 1995. A quarter-point move that sounds small, but for Japan, it's a significant milestone.

Here's what's driving it, and why it matters for investors around the world.

Why Japan Is Raising Rates

Japan is dealing with a problem it hasn't had in a long time: inflation.

The Iran war has pushed up global energy prices, and because Japan imports almost all of its energy, it’s particularly exposed.

Producer prices, which measure what companies pay for inputs, rose 6.3% in May, the fastest pace in over three years. That kind of cost pressure tends to filter through to consumer prices over time, and the Bank of Japan wants to get ahead of it.

There's also a currency problem. The Japanese yen has weakened significantly against the dollar, hitting around 160 yen per dollar and staying there despite the government spending the equivalent of roughly $73 billion in May alone on currency intervention.

A weak yen is a double-edged sword for Japan - it makes exports more competitive, which benefits manufacturers. But it also makes imports more expensive, which pushes up costs across the economy, particularly for energy, of which Japan imports almost all it uses.

One analyst summed up the intervention dilemma neatly: spending money to prop up the yen without changing interest rates is like tapping the brake while keeping your foot on the accelerator.

What This Means for Japan

The decision was reached by a 7-1 vote, with one dissenting member arguing that the risks from the Iran war were greater than the risks from inflation.

Japan's governor, Kazuo Ueda, was absent from the meeting after being admitted to hospital with a liver condition, making this the first policy meeting held without him since 2010. The deputy governor chaired proceedings and noted that one key factor in the decision was the recent memorandum between the US and Iran to extend their ceasefire, which reduced some of the uncertainty around energy supply.

The government has been trying to shield households from rising costs through subsidies and tax measures, which has kept headline consumer inflation below 2%. But those measures can only do so much, and the underlying pressure is building.

Higher rates should help strengthen the yen and contain imported inflation. But they also make borrowing more expensive for businesses and consumers in an economy where growth is already fragile.

Japan in the Global Context

Japan raising rates to 1% matters beyond Japan's borders for a few reasons.

Japanese investors have historically been some of the world's largest holders of foreign assets, particularly US government bonds, because returns at home were so low.

As Japanese rates rise, investing at home becomes more attractive by comparison. That means some of that capital could start flowing back to Japan instead, which reduces demand for US and European bonds, and can push their yields higher.

In plain terms, when a bond's yield rises, it means the price of that bond has fallen. So if you hold a global bond fund and Japanese investors start pulling money out of US or European bonds, the value of those bonds in your fund could dip.

It's also worth seeing this in the context of what's happening globally. The ECB raised rates last week, the Bank of Japan has raised rates this week, and in their upcoming meeting on Wednesday, the US Federal Reserve is expected to hold rates steady.

The direction of travel among major central banks is increasingly toward tighter policy, and that has implications for everything from mortgage rates to equity valuations to the cost of government borrowing.

For global investors, the direction of travel in central bank policy matters enormously. When several major central banks raise rates at once, investments that depend on cheap borrowing, like tech stocks and emerging markets, tend to struggle. Meanwhile, bonds and cash become more competitive, and the currencies of countries hiking rates tend to strengthen.

What This Means for Investors

If you hold global bond funds, higher Japanese rates are worth watching. As Japanese bonds become more competitive, some investors may shift money out of US and European bonds into Japanese ones. That reduced demand can push up yields elsewhere, which means the value of existing bonds in your fund could dip.

For anyone holding shares in Japanese companies, Japan has been one of the best-performing major markets this year, driven largely by AI and semiconductor stocks. The Nikkei 225 briefly crossed 70,000 points this week, a record, before pulling back slightly after the rate decision.

Japan is in the middle of unwinding three decades of extraordinary monetary policy. After 30 years of near-zero rates, that's not a small thing.
