The Bank of Japan today raised its benchmark interest rate to 0.5 per cent, the highest level in 31 years, as it finally begins to unwind decades of ultra-loose monetary policy. The move, which caught markets off guard, has sent the yen soaring and Japanese government bond yields spiking. But here in Britain, the reaction has been one of studied calm. The Chancellor’s fiscal discipline is looking increasingly prescient as global investors scramble for safe harbours.
Let us be clear: this is not a bolt from the blue. The BoJ has been signalling its intent to normalise policy for months. Yet the scale of the shift is startling. From negative territory to 0.5 per cent in little over a year, Japan is attempting a pivot that few central banks have managed without triggering a crisis. The history books are littered with cautionary tales: the 1994 bond crash, the 2013 taper tantrum. Japan’s debt-to-GDP ratio stands at over 250 per cent, making its fiscal position perilously exposed to higher borrowing costs.
The immediate effect has been a sharp repricing of risk. The yen has strengthened by more than 3 per cent against the dollar, a move that will sting Japanese exporters but offers a lifeline to importers of energy and food. More troubling is the impact on global bond markets. The yield on the 10-year Japanese government bond has risen to 1.5 per cent, dragging up yields in Europe and the United States as investors recalibrate their portfolios.
And where does that leave Britain? In a surprisingly strong position. The gilt market has been remarkably stable, with the 10-year yield barely budging. That is no accident. The Office for Budget Responsibility’s forecasts show the UK on track to meet its fiscal targets, with public sector net borrowing falling to 2.5 per cent of GDP by 2026. The Chancellor’s commitment to fiscal rules has earned the Treasury a reputation for prudence that is now paying dividends.
Consider the alternatives. The European Central Bank is still grappling with inflation above target and a fragile economic recovery. The Federal Reserve is walking a tightrope between rate cuts and rekindling price pressures. Meanwhile, the UK’s inflation rate has fallen to 2.1 per cent, within striking distance of the Bank of England’s target. The services sector remains sticky, but the overall picture is one of controlled disinflation without a recession.
Of course, no one is suggesting Britain is immune to global contagion. Capital flight from Japan could spill over into other markets. The yen carry trade, where investors borrow cheaply in yen to invest in higher-yielding assets elsewhere, is being unwound at speed. That could hit emerging markets and risk assets, including the FTSE 100. But the UK’s current account deficit, while still sizeable, is narrowing. And the pound has held its ground, trading above $1.25.
The key test will come in the weeks ahead. If the BoJ continues to hike, we could see a more disorderly sell-off in Japanese bonds. That would force the Ministry of Finance to intervene, as it did last September. For now, the signal from Tokyo is one of cautious normalisation. The BoJ’s governor has stressed that rates will remain low in real terms and that the central bank stands ready to adjust if necessary.
For Britain, the lesson is clear: fiscal discipline is the best defence against global market turmoil. The Chancellor should resist any temptation to loosen the purse strings in the forthcoming Budget. The headroom he has built up is not a windfall to be spent but a buffer against uncertainty. As Japan’s rate hike reminds us, the era of cheap money is over. Those who have prepared for that reality will be rewarded with stability.
The Bottom Line: Japan’s rate hike is a watershed moment, but Britain’s prudent fiscal policy offers a safe harbour. The market’s verdict is clear: stability pays.
