SWISS SIGHT DEPOSITS FALL 2.88 BILLION FRANCS Sight deposits of commercial banks at the Swiss National Bank fell 2.88 billion Swiss francs in the first 10 days of March to 7.65 billion, the National Bank said. Foreign exchange reserves rose 3.30 billion francs to 33.94 billion. Sight deposits are a major indicator of money market liquidity in Switzerland. The National Bank said banks paid back 5.5 billion francs of central bank credit taken out at the end of February for the end-month liquidity requirement. This drain was offset in part by new currency swaps, which had the effect of increasing the National Bank's foreign exchange holdings. Bank notes in circulation fell 309.1 mln francs to 24.49 billion, and other deposits on call -- basically government funds -- rose 1.06 billion to 2.10 billion.
