Banking fears ease, dollar gains against yen.

The dollar rose against the yen as authorities' efforts to calm investor nerves over the global banking system helped ease fears of contagion in Europe. The US currency traded in a narrow range against most major currencies as investors sought clarity on the fallout from the recent collapse of two US lenders and the rescue of Credit Suisse. The Federal Deposit Insurance Corporation said First Citizens BancShares would acquire all of Silicon Valley Bank's deposits and loans from the regulator, which helped ease some fears of contagion in Europe.
