THE pound has hit a new post-Brexit vote high versus the US dollar, despite concerns over what Carillion's collapse will mean for the wider UK economy.

Sterling climbed 0.5 per cent against the greenback to 1.380 - marking the highest level for the currency pair since June 24, 2016. That was compared to flat trading against the euro, with sterling at 1.125.

US dollar weakness was one of the main drivers, amid fears that monetary policy will tighten quicker overseas where inflation is rising.

Michael Hewson, chief market analyst at CMC Markets UK, said: "The US dollar index has continued its slide, hitting three-year lows against a basket of currencies, as speculation about tighter monetary policy elsewhere in the world weighs on the greenback."

The fall in the dollar helped to offset worries over the pending liquidation of construction and outsourcing giant Carillion.

"The pound has also found further support trading above the 1.3800 level for the first time since 24th June 2016, the day after the Brexit vote, despite concerns about the effects that Carillion's collapse might have on the UK economy," Mr Hewson said.

Carillion - whose shares were suspended before the market opened - entered into compulsory liquidation this morning after failing to secure more money from lenders.

The company was understood to have public sector or public/private partnership contracts worth £1.7 billion - including providing school dinners, cleaning and catering at NHS hospitals, construction work on rail projects such as HS2 and maintaining 50,000 Army base homes for the Ministry of Defence.

Many small firms are also waiting for Carillion to pay bills going back several months.

The long term affect of Carillion's collapse is expected to take some time to realise.
