Thomson Financial News - There's certainly chatter emerging amongst London traders suggesting that a tighter monetary policy may be seen from the Bank of England, but arguably it's going to take some real evidence that this is under consideration before the pound can start to realistically price in this option. As a result, expect next week's BoE meeting minutes to be under close scrutiny for any clues but in the interim, any real support may be difficult to establish although readings such as today's trade balance and unemployment data could present the opportunity for some posturing amongst traders.
