The US greenback was still trading at KD 0.284 Sunday, while the Euro gained to trade for KD 0.370 and the Pound Sterling came down to KD 0.424 compared to Thursday, said the Central Bank of Kuwait (CBK) bulletin.  The CBK said the Japanese Yen was unchanged at 0.003 and that the Swiss Franc was also unchanged at 0.299.  The mixed financial data in the US is having some effect on the market, as is the decision in Europe to maintain current interest rate amid the Euro zone\'s continued poor performance.
