The American economy continues to defy expectations, posting a 2.8% annualised growth rate in the third quarter. This figure, released by the Bureau of Economic Analysis, underscores the persistent resilience of the world's largest economy. Yet for British Chancellor of the Exchequer, it is a signal to fortify the UK's own defences.
In a speech at the London School of Economics, the Chancellor described the transatlantic divergence as a 'call to action'. The UK economy, he noted, has grown at less than half the US pace over the past year. 'We cannot rely on American dynamism alone to lift global growth,' he said. 'We must build sovereign resilience against shocks that are now endemic to the system.'
The Chancellor's phrasing is deliberate. The term 'sovereign resilience' echoes the language of energy security and supply chain redundancy. It is a pivot away from the post-2008 consensus that globalisation and interdependence were net positives. Now, the question is whether nations can insulate themselves without retreating into protectionism.
The data suggest the US has leeway to maintain its growth trajectory. Consumer spending, supported by a robust labour market, continues to drive the economy. Inflation has moderated to 2.4%, though core services remain sticky. The Federal Reserve is expected to hold rates steady, a luxury the Bank of England does not share with UK inflation at 2.6%.
The Chancellor's call for resilience is rooted in physics as much as economics. The global economy, like a complex system, is subject to cascading failures. A war in Europe, a drought in the Panama Canal, a chip shortage in Asia: each stress test reveals vulnerabilities. The UK, with its large financial sector and heavy reliance on trade, is particularly exposed.
But what does resilience mean in practice? It is not autarky. The Chancellor proposed targeted state investment in critical minerals, energy storage, and AI-driven logistics. He also endorsed a 'strategic autonomy' fund to support industries deemed essential. Critics on the left argue this is insufficient; on the right, that it overreaches. Yet the administration's own advisory body, the National Infrastructure Commission, has estimated that climate-related shocks alone could cost the UK up to 3% of GDP annually by 2050.
The irony is that US growth itself contributes to global volatility. American demand for energy and metals strains supply chains. Its tech sector consumes vast amounts of water and rare earths. The hydrocarbons that fuel its growth produce emissions that will eventually hit British shores as extreme weather.
The Chancellor's speech passed largely without market reaction. Sterling dipped marginally but recovered. The FTSE 100 barely moved. Yet the silence from Whitehall was notable. The Treasury is reportedly drafting a white paper on economic security, due next quarter.
What is clear is that the era of cheap globalisation is over. The US can grow because it has terrain, resources, and demographic firepower. The UK must grow smarter. That means investing in the physical and digital infrastructure that strengthens the system's nodes. It also means accepting that resilience has a cost.
For the climate correspondent, this is the crux. The biosphere collapse does not respect sovereign resilience. Carbon is a global pollutant. A flood in Scotland and a hurricane in Florida share the same atmospheric driver. The Chancellor's framing, while politically astute, risks omitting the planet from the equation. True resilience lies not in insulation but in cooperation. The UK's net zero targets are legally binding. The US has none. Until that gap is closed, any talk of resilience is merely preparing for a losing battle.
As I type, the Keeling Curve continues its relentless climb. Carbon dioxide levels have just crossed 423 parts per million. The last time the Earth saw such concentrations, humans did not exist. The Chancellor's words are necessary. The actions that follow must be proportionate to the scale of the challenge. Otherwise, the growth we protect today will be erased by the collapse we fail to prevent.
