How not to run a country

It was meant to usher in an era of economic growth. Instead the 25-minute statement that Kwasi Kwarteng, Britain’s new chancellor of the exchequer, gave on September 23rd kickstarted a crisis. By unveiling £45bn ($48bn) of unfunded tax cuts, alongside temporary measures to help with energy bills, Mr Kwarteng spooked financial markets in spectacular fashion. Most of the tax cuts and emergency spending had been signalled, but the vaunted supply-side reforms needed to pay for them were vague and the new government’s approach to the public finances was cavalier. Worse, the backdrop to Mr Kwarteng’s epic budget-busting was a slump in bond markets that raised borrowing costs for even the most creditworthy governments.
