NAIROBI (Reuters) - The Kenyan shilling was steady on Monday with traders expecting it to weaken moderately this week after the central bank moved to inject cash into liquidity-squeezed money markets. At 0806 GMT, commercial banks quoted the shilling at 84.80/85.00 per dollar, the same level it closed at on Friday. "For now banks are finding it hard to go long on dollars because of the tight liquidity," said Ignatius Chicha, head of markets at Citibank. "Once liquidity improves we might see a push for the currency to depreciate." The central bank sought to pump in 16 billion shillings into the market through reverse repurchase agreements (repos). The currency has been trapped in the 84.50-85.00 range this month as tight liquidity on money markets makes it expensive for banks to hold long dollar positions. Tight liquidity in the market was caused by a bond auction and payments to tea farmers for their crop. The overnight weighted average interbank rate rose to 11.4889 percent on Friday from 11.3151 percent on Thursday, having risen gradually from 6.9383 on September 17. "With end month just around the corner we expect the shilling to come under moderate pressure this week," said Bank of Africa in a daily note.
