The pound hit a six-week high as Rishi Sunak became prime minister, another sign of the markets welcoming the country's new leader. Sterling was up 1.8% against the dollar at $1.147, having risen by 1.92% to $1.150 earlier in the day - the highest level since 15 September.
The strong dollar had been weakened over signs that the American central bank, the Federal Reserve, would further raise interest rates and slow the world's biggest economy. The pound had been hovering at around $1.11, as reports emerged that Boris Johnson was planning a political comeback in a challenge to Sunak. Sunak is a known name to the UK's financial sector, having been chancellor for two years under Johnson and a former Goldman Sachs analyst and hedge fund partner before that, and it is hoped his administration will steady the markets. He comes to the top job after Liz Truss announced big tax cuts late last month, spooking investors and prompting a massive sell-off of government bonds that forced the Bank of England to intervene.
Putting Jeremy Hunt in the chancellor's role, replacing Kwasi Kwarteng, went some way towards calming the situation, as Hunt rowed back on almost every policy that had been announced in the Truss-Kwarteng mini-budget. Long-dated gilt yields, which were at the centre of the post-mini-budget chaos, have almost returned to where they were beforehand, reflecting growing investor confidence.
Hunt said on Twitter: "It is going to be tough, but protecting the vulnerable - and people's jobs, mortgages and bills - will be at the front of our minds as we work to restore stability, confidence and long-term growth."
Jordan Rochester, a Nomura strategist, said: "Every new leader tends to get a honeymoon period and Liz Truss's didn't last very long. The question will be how long does this honeymoon period last for Rishi Sunak? We assume he has a better understanding of financial markets than Liz Truss - with his background - and that he will allow Jeremy Hunt to continue this 'austerity budget.'
