The US investment bank said there is a danger Britain’s toxic mix of problems will come to a head as soon as next year, triggered by fears that Westminster may prove unable to restore fiscal credibility.
“Growing fears over a hung parliament would likely weigh on both the currency and gilt yields as it would represent something of a leap into the unknown, and would increase the probability that some of the rating agencies remove the UK's AAA status,” said the report, written by the bank’s European investment team of Ronan Carr, Teun Draaisma, and Graham Secker.
“In an extreme situation a fiscal crisis could lead to some domestic capital flight, severe pound weakness and a sell-off in UK government bonds. The Bank of England may feel forced to hike rates to shore up confidence in monetary policy and stabilize the currency, threatening the fragile economic recovery,” they said.
