Britain tests ‘the kindness of strangers’ as gilts lose their lustre

It was a dire warning. Chancellor Kwasi Kwarteng was told in no uncertain terms last September that his financial war chest was evaporating.

The Office for Budget Responsibility’s decision last week to publish previously blocked forecasts showed the headroom to cut taxes or raise spending was down from £29bn in March 2022 to just £8.8bn by that autumn.

Kwarteng pressed ahead with his £45bn tax-cutting plan. Markets took fright and Kwarteng and his prime minister Liz Truss were relegated to the backbenches. The moron premium of the Truss era became a self-styled dull dividend as Jeremy Hunt and Rishi Sunak entered Downing Street.

But nine months after the debacle, markets have not fully settled.

The British Government has to pay an interest rate of 4.3pc to borrow for 10 years. This is above the 3.94pc markets currently charge the US or the 2.5pc paid by Berlin.

It’s not a position the current Chancellor wants to be in. Until the turmoil last autumn, the UK tended to pay a lower rate than the US. And pre-Covid, the gap between British and German rates was barely half the current spread. Buying British still has a premium.

That’s bad news for the Government. With the national debt mountain now equivalent to the size of the economy, higher borrowing costs are dragging on the public finances.

According to ratings agency Fitch, the Government will spend £110bn on debt interest this year, equivalent to around one pound in every 10 that the Exchequer raises, the highest ratio of any rich nation.

With tectonic shifts expected in the bond market this year as even the Japanese start thinking about higher borrowing costs, the implications for taxes, spending and the upcoming election are huge.

James Lynch, investment manager at Aegon, says the legacy of political risk combined with fears the UK is more exposed to inflation than other nations suggests Britain is more vulnerable to a surge in borrowing costs.

“The politics, the inflation, the cost of living, the wages and the Bank of England response has all been a bit more heightened in the UK than in other areas,” he says.

Overcoming this is not a simple matter.

Higher inflation means investors demand a higher return on bonds to guard against the value of their cash being eroded by rising prices.

The Bank of England must also shoulder the blame for failing to convincingly get on top of price rises.

Orla Garvey, portfolio manager at Federated Hermes, says a disciplined response is needed to give investors more confidence in the UK.

She says: “The market is very keenly aware of the debt burden and of higher inflation, so it is really important the Government is credible in its fiscal response and the Bank of England is credible in its monetary response.”
