Agree. Euro, Gold, USD all gone up, it's too late now.
Hedge into another currency will cost you at least 5%. (Simply change your STR to USD and get it back immediately) Plus the interest rate you can get in UK is around 3%. That means, hedge your STR only if you believe it will soon lost at least 8%.
Therefore, I am betting on pound will hold its value for at least next 12 months.
UK economy is in bad shape now but there are many worse countries out there. For example, Iceland, Ukraine....etc. Those countries doesn't have hyperinflation so far. I cannot see why UK will have hyperinflation alone.
Even if global hyperinflation become real... where else do you want to live? I will still stay in UK because other countries have higher probabilities of civil unrest.
In conclusion, keep STR is safe bet to me.
