* Graphic: World FX rates in 2020 tmsnrt.rs/2RBWI5E LONDON, Dec 22 (Reuters) - The euro and the pound were on the defensive against the dollar on Tuesday as a new coronavirus strain spread across Britain, closing key trade routes and creating a supply-chain nightmare while time was running out to strike a post Brexit trade deal. Talks between the French and British governments to reopen their border, where hundreds of trucks are stranded, and reports suggesting movement in Brexit talks have however helped to take some pressure off both currencies. At 0802 GMT, the euro was down 0.31% at $1.2209 while the pound was losing 0.33% at $1.3422, recovering some ground after a fall as steeply as 2.5% during the previous trading session. The British currency was also flat at 90.95 pence against the euro after sustaining heavy losses amid the transport crisis on Monday. “New hope for a (Brexit) deal before Dec. 30 and talks between the British Prime Minister and the French President on the supply of goods to the island have again nurtured new hope and made EUR-GBP briefly look below the 0.91 mark”, said Commerzbank analyst Ulrich Leuchtmann. Another positive for the pound was data showing that the country’s economic recovery from its coronavirus crash was a bit quicker than previously thought in the July-September period. The dollar index, which measures the currency’s strength against a basket of currencies rose 0.16% at 90.279 after the U.S. Congress settled on a new U.S. stimulus package. In Asia the Australian dollar fell 0.4% at $0.7554 while the New Zealand dollar lost 0.55% to 0.7065. The yuan, which has gained nearly 10% on the dollar since a March low, has been steady for about a week now and was a fraction softer at 6.5448 per dollar on Tuesday. The dollar’s gains come in a market that is heavily positioned for a weaker greenback and pricing a pandemic recovery that lifts commodity prices and benefits exporters and their currencies at the expense of the greenback. The value of overall bets against the dollar eased a fraction last week, positioning data showed, but remains near nine-year highs struck in September.
