LONDON: Sterling plunged on Tuesday to a 13-month low versus the euro and fell below $1.20 for the first time since the start of the pandemic after Scotland’s First Minister Nicola Sturgeon said she was set to share details on plans for a new independence referendum. Sturgeon said she was nearly ready to give more details on how Scotland’s devolved parliament could move ahead with a new independence referendum without the consent of the British government.

British Prime Minister Boris Johnson does not believe now is the time to be talking about another referendum on Scottish independence, his spokesman said.

Johnson and his Conservative Party, which is in opposition in Scotland, strongly oppose a referendum, saying the issue was settled in 2014 when Scots voted against independence by 55% to 45%.

Versus the euro, the pound fell 1.2% to 86.81 pence, its lowest level against the single currency since May last year.

After rising against the dollar earlier in the day, the pound fell 1.1% to $1.1993, its lowest level since March 2020. “If I were to isolate the (pound) move lower down to one event, I’d most probably say that the Scottish independence risk was the straw that broke the camel’s back,” said Simon Harvey, head of FX analysis at Monex Europe.

Sterling has weakened more than 11% against a robust dollar since the start of the year amid a grim outlook for the economy and political instability in Britain. Data on Tuesday showed the UK jobless rate ticked higher in the first increase since late 2020.

Britain’s growth is seen among the weakest for rich countries in the coming months, and there is uncertainty over how fast the Bank of England, which is expected to raise interest rates again on Thursday, can tighten policy this year to tame inflation without further hurting the economy.
