Jane10,
My son met Carney and the Deputy Governor, Ben Broadbent, a few weeks ago. They are both very professional (as one would hope) and know their stuff. They both know very well that we're in for a rocky ride and are doing their best to calm the markets, but they can't control the markets. £600bn is available to support the pound, but that will appear on the balance sheet as a debt for decades and will inevitably affect confidence in the UK. The Japanese have already advised de-investment and others will follow.
