un-costed tax cuts and an open ended promise to pay for the spike in energy prices spooked investors and caused a run on the pound and (worse) a collapse in the value of UK debt. This threatened to cause a run similar to the 2008 US mortgage backed securities crash because a lot of investors (including many if not most UK pension funds) used their UK debt as collatoral for more loans. If the price falls to far too fast they have to sell their UK debt at distressed prices to meet margin calls and this drives the price down further. The Bank of England has stepped in to prop up the market by printing more money (which means more inflation).

Interest rates are now expected to triple to 7% to cope with this fiscal event and as most UK home owners borrow money on revolving short term loans to buy houses many people are looking at a $1,000-$2,000 / month increase in interest payments and a 20% collapse in the value of property.

Most major businesses have gone into crisis mode (hiring freeze, paused expansion plans) which will have its own knock on consequences. If we're very very lucky it won't spread to other countries.
