Dollar Gains Most Since May on Confidence Over Fed Rate Increase

The dollar posted its biggest weekly advance since May amid a growing conviction that U.S. economic growth will prompt an interest-rate increase from the Federal Reserve this year.

The U.S. currency gained for the first time in four weeks versus the euro as investors, speculating that an 11th-hour deal will be reached on Greek aid, turned their attention to monetary policy and the economy. A report showed June consumer sentiment reached a five-month high.
