This is Truss and Kwarteng’s crisis, not yours – but you’re already a lot poorer because of them | Aditya Chakrabortty

In 25 years of reporting, I have never seen a financial crisis so utterly avoidable, and dragging so much human misery in tow

British politics is being reshaped this week - but not because of Keir Starmer. After only 22 days as prime minister, Liz Truss is already facing her demise. Party conferences, those jamborees of suited choreography and confected excitement, look utterly irrelevant beside the financial meltdown engulfing the country. Yet politics and finance are, in this moment, deeply bound up with each other. This crisis was largely manufactured by our failing political class and it will now determine their terms of trade. For the rest of us, the result threatens to be austerity 3.0: the third big wave of spending cuts to follow the third crisis in the last 12 years, with even more social wreckage and human misery in tow.

I covered my first financial crisis 25 years ago, in 1997, and I have never before seen one so entirely avoidable as this is. It began with the Tory leadership election in the summer, when Liz Truss promised tax cuts of 30bn in order to win the keys to No 10. It picked up last Friday, as Kwasi Kwarteng unveiled his plan for growth", which turned out to be a further 15bn of handouts - and mainly to people who didn't need them.
