Lithuania must be smarting. It became the eurozone’s 19th member last week, just as the currency fell to its lowest level against the U.S. dollar since 2006. Priced at $1.1861, the euro is being pressured by the likelihood that the European Central Bank will pump more money into the economy to steer clear of deflation. The dollar also surged against British, Canadian, Australian and Swiss currencies. So while Lithuanians may need to sit tight for a while, Americans should be making travel plans, pronto.
