* A week of interest rate decisions... * Pound Sterling drops again... * Brazil and Mexico continue to dominate... * Gold and Silver fall... ** A week of interest rate decisions... Good day...The dollar stayed in the pretty tight range it has established over the weekend, gaining some strength over the weekend after losing some ground on Friday. Should be an exciting week as it is 'Interest Rate Decision' week as a number of central banks will be announcing their new rates. I think the rate announcements will reinforce my feelings that the world's economies are heading down divergent paths, with some economies heading down a recessionary path while others maintaining good growth rates. As expected, the US unemployment rose to the highest level in more than four years as employers cut jobs again in July. But the decrease in payrolls was slightly less than forecast, so some were saying 'it isn't as bad as we thought'....
