Question is...how much longer do you think you'll get 5% in the UK?

Guess it all depends on whether you think you might need the money or not. Or whether the money is now in Swiss Francs or GBP. It's a great time to be moving francs into pounds...but what happens if you need to change those pounds back into francs? You're at the mercy of FX rates.

In the end, it all depends on your own circumstances and only you can decide!

Hope this helps!
