Why is the exchange rate from USD to GBP increasing?

I live in the US and I often buy CDs (Compact Discs, not certificates of deposit) from the UK. For the past year so A USD was worth about .5 GBP, or even a little less. I assumed this was because of the state of the economy. The economy, however, is seemingly worse then ever, yet the USD seems to be worth about .6 GBP. Will it continue in this direction? That would be phenomenal I hate paying upwards of 20 bucks for a single CD! |||I am not so sure its at .6GBP per dollar but you can expect it to be close or even grow more than that should the royal banks and treasuries not get thier bailouts sorted. the british traders right now are much more jittery right now and the speculation over trade in the entire world is causing problems all over the place the only one to benefit from this will be the US mark my words in 2009 the US stock market will be like no other it will be the bull market of the centuary of course
