Alagomeji,
When I bought my rental property in the UK, I opened a bank acount in the Isle of Man. It's called an Offshore Account, and it's in British Pounds Sterling. I transferred money into this account as proof of savings to live off of for HSMP & EC documentation.
You do not have to be a British citizen or resident to open one of these offshore accounts. You do however have to provide quite a bit of documentation, but it is worth it to be able to mobilize all your money into British Pounds Sterling when the time comes (i.e., when you get the HSMP approval letter).
The big question here (Rhetorical): Will the currency value keep dropping or will it go up again? Without an answer to this question, it is hard to know whether to move all money now or wait out the 'storm' for a better rate.
