Quite whether he displayed sound judgement during his terms as Chancellor and PM, however, is somewhat more debateable. Bear in mind that this is the man who sold more than half of the UK’s gold reserves at the bottom of the market (to "diversify our portfolio), who presided over an enormous expansion in non-productive government spending (long pre-dating the banking crisis) , and who was instrumental in the destruction of the nation’s private pension schemes. Also bear in mind he transferred responsibility for supervision of the banks to the supine FSA, removed the 10% tax band, and increased the nation’s overall tax bill from 39% of GDP to more than 42% in a bit over ten years.

I’m not so sure Mr Schwab would quite see it this way, though.
