Sir John conceded that the knock-on effects of recession could have a major impact for the taxpayer, which now owns huge swathes of the banking system. Asked whether the taxpayer is likely to lose out, he said: "Well I think it'll be a mixed picture. I mean I think there are some [lending] books, Northern Rock, Bradford & Bingley, which the taxpayer is now holding which clearly have a level of defaults in them. I'm not quite sure how that will balance out against the residual of the capital. As for the more mainstream banks, yes I think they've got a commercial future and I'm sure that in time they will, as for example the Swedish banks have after their crisis, revive and start building and growing as commercial entities again."
