Published by Mark AckroydForeign exchange trading experts in London could have suffered a knockback this morning (December 12th) as sterling fell in value versus the dollar.According to Reuters, the UK currency dropped to $1.5553 by 09:15 GMT, a new low for the day.It is said by the news source that this is on the back of increased wariness among investors relating to the European Union (EU) summit talks.Peter Kinsella, currency strategist at Commerzbank, said the eurozone has done well to commit to new, tighter regulations, but there are still some matters to be resolved."We still don't have an effective implementation regime in the EU, so nothing has changed on a fundamental basis," he stated, adding: "I don't see any reason for sterling to rally."There was better foreign exchange trading news for UK investors at the back end of last week, when sterling recorded a small rise against the euro.For more information on foreign exchange treasury services and risk management, visit our Corporate FX site
