The U.K. currency was less than 0.4% of its lowest level in a 2 ½-year period against the U.S dollar as a data showed the largest decline in U.K. construction output in more than 3 years in February. The pound dropped below $1.50 on March 1, the lowest figure since July 2010, and was at $1.5036 earlier on Monday's session as a construction activity index slid from 48.7 to 46.8 in February.
