The American economy, much like a stubbornly overvalued stock, continues to defy gravity. GDP growth for the last quarter clocked in at a robust 3.2%, far exceeding the anaemic 1.5% the consensus had priced in. Yet, as markets cheer this aberration, the prudent observer must ask: at what cost? The answer, it appears, lies across the Atlantic, where British fiscal discipline has provided the anchor for global stability, however unwittingly.
Let us dissect the numbers. US consumer spending, the engine of this expansion, rose 4.8%. But this is not a story of organic growth. It is a tale of unsustainable stimulus, a sugar rush fuelled by deficit spending that would make even a Keynesian blush. The US federal deficit now stands at 6.4% of GDP, a level typically reserved for wartime recessions. Meanwhile, the UK, having endured the pain of austerity and the discipline of a tight fiscal straitjacket, posts a deficit of just 2.1%. The contrast is stark.
How does British prudence prop up the US boom? Through the bond market, of course. Gilt yields, the benchmark for risk-free assets, have remained remarkably stable, anchored by the Bank of England's commitment to inflation targeting and the Treasury's credible medium-term fiscal plan. This has kept global borrowing costs lower than they would otherwise be. US Treasury yields, while elevated, would be sky-high absent the calming influence of UK fiscal rectitude. The capital that might have fled to Germany or Japan has instead flowed into London, providing a buffer for the global financial system.
But the market is not fooled. A flight to quality is underway, with sterling appreciating 2.3% against the dollar over the past month. Currency traders recognise that the US growth story is a mirage, a reflection of borrowed time. The British economy, though sluggish, is built on foundations of sound money and fiscal responsibility. As the US debt pile grows, the risk of a sudden loss of confidence looms. The term premium on US Treasuries is creeping up, a warning signal that investors are demanding higher compensation for holding American paper.
Critics will argue that British austerity has choked growth. They are missing the point. The UK's GDP growth of 1.2% may be pedestrian, but it is sustainable. The US 3.2% is a statistical illusion, a consequence of government borrowing that will eventually crowd out private investment. When the reckoning comes, and it will come, the British economy will be better positioned to weather the storm.
Central bank policy further underscores the divergence. The Federal Reserve, trapped between inflation still above 3% and a deteriorating fiscal outlook, is forced to keep rates high. The Bank of England, having already tightened sufficiently, can afford to pause. The result: UK inflation is converging to target faster than US inflation. The pound's strength is a vote of confidence in British monetary credibility.
To the casual observer, the US economy appears vibrant. To those of us who follow the bottom line, it is a dangerous game of financial chicken. The British approach, for all its pain, is the tortoise to the American hare. And we all know who wins that race. The market will eventually price in reality, and when it does, the US will face a brutal correction. British fiscal discipline will be the shield that protects the global economy from total collapse. But do not expect a thank you from Washington.
In the meantime, investors should look to UK gilts as a safe harbour. The yield is modest but the security is paramount. The US party will end, and when the hangover strikes, the British prescription of fiscal sobriety will be the only cure.
