DEALERS WARY OVER STERLING INTERVENTION RUMOUR Foreign exchange market rumours that the the Bank of England has been selling sterling to halt its rise prompted a wary response from dealers who said they saw no obvious confirmation, market sources said. Bank of England officials were not immediately available for comment. Earlier this week, the Bank sanctioned a cut in bank interest rates in a surprise move, which aimed at limiting sterling's rise ahead of the March 17 budget. But today the pound has strengthened to 72.7 on its trade-weighted index from 72.1 last night, though the U.K. Currency is below its day's high against the dollar.
