The financial establishment is once again holding its breath as Donald Trump’s unconventional affection for inflation sends tremors through global bond markets. While UK consumer prices have remained stubbornly steady, the US is facing a surge that has the Treasury in a cold sweat. The President’s recent remarks, embracing higher inflation as a tool for economic growth, have left investors questioning the Federal Reserve’s independence and the stability of dollar-denominated assets.
For those of us who have watched the City of London’s pulse for two decades, this is a worrying sign. Inflation is not a pet to be coddled; it is a beast that, once unleashed, devours purchasing power and erodes the value of fixed-income securities. The UK’s Consumer Prices Index (CPI) has been hovering around 2% target, a testament to the Bank of England’s steady hand. But across the pond, US CPI is running hot, with core inflation at 3.6% and showing no signs of cooling.
Trump’s rhetoric is a departure from decades of orthodoxy. ‘A little inflation is a good thing,’ he claimed, ‘it means we’re growing.’ To any finance professional, this is akin to a pyromaniac declaring that a little fire is good for heating. Inflation, once embedded, is notoriously difficult to extinguish. The bond market is already voting with its feet: the US 10-year Treasury yield has spiked to 4.7%, while the UK gilt yield has remained relatively anchored at 4.1%. That gap is a signal of capital flight, and it’s not flowing in the direction of the White House.
The implications for the UK are nuanced. A stronger dollar typically hurts emerging markets, but for a net importer like Britain, a weaker pound could exacerbate import costs. However, the Bank of England’s cautious tightening cycle has kept the lid on domestic price pressures. The risk is contagion: if US inflation forces the Fed to hike aggressively, the dollar could strengthen further, putting pressure on the pound and forcing the BoE to raise rates to defend the currency.
There is also the matter of fiscal discipline. Trump’s tax cuts and spending plans have already ballooned the US deficit to 6% of GDP. Inflation is a convenient way to erode the real value of debt, but it punishes savers and retirees. The UK, under Rishi Sunak’s government, has been preaching fiscal responsibility, but it remains to be seen if that can survive the next election cycle.
Gilt yields have been remarkably stable, but they are not immune. The divergence between US and UK inflation rates creates a carry trade opportunity: borrow in dollars, buy UK gilts. But that trade unwinds quickly if inflation expectations shift. The MPC must remain vigilant.
In my view, Trump’s love affair with inflation is a dangerous flirtation. The market is not a romance novel; it is a cold, hard ledger. And right now, the ledger shows that the US is losing credibility on price stability. For UK investors, the lesson is clear: diversify, hedge, and keep a close eye on the dollar-sterling exchange rate. The bottom line is that inflation, unlike Trump, is not something you can simply tweet away.
