Research firm Markit and the Chartered Institute of Purchasing & Supply said on Monday that their U.K. construction purchasing managers' index fell to 46.0 in June from May’s reading of 51.2. Economists had expected the index to drop to 50.5 in June.

The pound has already been under heavy selling pressure since Britain shocked markets by deciding to leave the European Union, sparking uncertainty over the consequences of the U.K. vote on the country’s economy and the global economy as a whole.

Adding to pressure on the U.K. currency, Bank of England Governor Mark Carney indicated late last week that more stimulus may be needed over the summer, fuelling expectations for an upcoming rate cut.
