The Treasury is monitoring events in Jakarta with the kind of nervous attention usually reserved for a gilt auction gone wrong. As Indonesian students take to the streets to protest fuel price hikes, officials fear the fiscal fallout could spread to Britain's own fragile public finances. I have spent two decades watching emerging market wobbles ricochet through the City, and this one has all the hallmarks of a classic capital flight episode.
The trigger is straightforward enough: the Indonesian government, facing a budget deficit that has ballooned to 3.5% of GDP, has cut fuel subsidies. Petrol prices have jumped 30% overnight. The students, understandably, are furious. But the Treasury's concern is less about social justice in Southeast Asia and more about the mechanics of contagion. When a major commodity exporter like Indonesia raises fuel prices, it signals deeper fiscal stress. Global investors take note. They demand higher risk premiums. They sell off emerging market bonds. And then, because money is a coward, they flee to safe havens like US Treasuries and, yes, British gilts.
This would be good news for a short-seller but not for a Chancellor trying to keep borrowing costs down. The irony is rich: a fuel price revolt in Indonesia could push up UK gilt yields. That would increase the cost of servicing our £2.5 trillion national debt, eating up fiscal headroom and tightening the screws on public spending. Every basis point rise in gilt yields adds millions to the interest bill. The Treasury is already sweating over this, with inflation still stubbornly above target and the Bank of England signalling further rate rises.
The market dynamics are textbook. The Indonesian rupiah has already dropped 2% against the dollar, and the Jakarta stock index has shed 4% this week. If the protests escalate, capital controls or a rate hike by Bank Indonesia could trigger a broader sell-off. British pension funds and asset managers hold significant emerging market debt. A rout would hit their balance sheets, reducing their appetite for UK government bonds. That is the contagion channel the Treasury fears.
Let me be clear: this is not 1997 or 2008. The global financial system is more resilient. But the parallels with the 2013 taper tantrum are uncomfortable. Emerging markets have been living on cheap money for years. Now that US interest rates are rising, liquidity is draining. Indonesia is the canary in the coal mine. If the students stay on the streets, the mine might collapse.
The Chancellor's options are limited. He could jawbone about fiscal discipline, but markets listen to actions not words. The one calculation that matters is the pound's exchange rate. A weaker pound boosts exports but imports inflation. Given that the UK imports much of its energy, a falling pound would exacerbate the cost of living crisis. That is a political nightmare.
So what is the bottom line? The Indonesian student protests are a reminder that fiscal irresponsibility has consequences. The UK is not Indonesia, but our own debt pile is hardly a model of prudence. If the contagion spreads, we could be next. The Treasury is right to be nervous. I am watching the rupiah, the 10-year gilt yield, and the student barricades in Jakarta. All three will tell us whether this is just a tremor or the start of something bigger.
