LONDON (AFX) - The euro gained on the dollar as the US trade deficit rose to a record high in May, confounding consensus estimates, dealers said. "The numbers will help the euro along. There was a quick spike when the figures came out," David Mann at Standard Chartered said. Mann believes the US trade deficit will widen further over coming months as the effects of a weaker dollar kick in. The US trade deficit for goods and services widened to a seasonally adjusted 37.6 bln usd in May from a revised 36.1 bln in April. In percentage terms, the trade deficit widened to 4.1 pct - the largest deficit since records began in Jan 1992. The data was unexpected. A consensus forecast of Wall Street economists polled by AFX News called for the deficit to narrow to a seasonally adjusted 35.14 bln usd. At 1.42 pm, the euro was at 1.0155 usd from 1.0139 usd before the news.
