The blue-chip FTSE 100 index dipped 0.1% on Friday but was on pace to gain 1.06% for the week with banks and travel stocks being the top gainers. The mid-cap index gained rose 0.2%. The Bank of England gave British lenders at least six months’ breathing space on Thursday before negative interest rates are a possibility, focusing instead on the prospects of a post-lockdown rebound. Progress in vaccine distribution and expectations of a large stimulus by U.S. President Joe Biden’s administration helped global markets trade near their record highs. Insurer Beazley jumped 7.2% and was the top gainer on the mid-cap index after it said it was confident of returning to profitability in 2021.
