Sterling takes a pounding as euro soars on back of Mario Draghi comments
The pound tumbled to an eight-month low against the euro after European Central Bank (ECB) president Mario Draghi signalled potential changes to its bond buying programme could be discussed in the autumn.
The news sent the euro soaring, knocking the pound down 1.3% to trade at 1.116 against the European currency, marking its lowest point since early November.
Sterling was also in the red versus the US dollar, down 0.3% at 1.298.
Investors have been closely watching the ECB for any news of monetary policy tightening, which would signal growing confidence in the eurozone economy.
Neil Wilson, a senior market analyst at ETX Capital, said: "Draghi offered precious little new but what he did let slip is that the Governing Council is likely to discuss tapering in the autumn."
He added: "Whether September counts as the autumn, Draghi was less willing to comment on.
"It wasn't much but the market is super-sensitive to anything from Draghi at the moment."
The drop in the pound sent the FTSE 100 higher by 0.77% or 59.96 points to 7,487.87.
