No positive spin can be put on any of the latest developments. Banking shares have taken a beating; China’s slowdown continues; Maersk, the shipping giant, believes that conditions for world trade are worse than in 2008-09; industrial production slumped in December, not just in Britain but more so in France and Germany; energy prices are devastating Middle Eastern and Russian economies; and sterling has tumbled.

It is always a sure sign that panic has broken out when financial markets respond badly to all possible scenarios. The prospect of higher interest rates? Sell, sell, sell. A chance of lower rates? Sell, sell and sell again. A rise in the price of oil is met with as much angst as a decline. The financial markets remain addicted to help from central banks: they are desperate for yet more interventions, regardless of the consequences on the pricing of risk, the allocation of resources or the creation of unsustainable bubbles that only enrich the owners of assets.

This is exactly the tonic that the populists have been waiting for. Despite their dramatic emergence, they have so far failed to make a real breakthrough. The SNP was unable to win the Scottish referendum and the National Front didn’t gain a single region in France. Mariano Rajoy remains Spain’s prime minister, and anti-establishment parties have been thwarted in Germany. Even lighter forms of populism, such as Ed Miliband’s, were rejected. Syriza’s victory in Greece was one of the few genuine populist triumphs; but it was soon crushed by the combined might of Brussels and Frankfurt.
