The ignominious collapse of the Dunfermline Building Society is more of a nuisance than a heart-stopping moment in UK finance. And maybe everyone is a little jaded by bail-out Mondays. Still, the lack of detail from the government is striking.

We know it is taking on Dunfermline’s unwanted assets, mainly commercial loans and some dodgy residential mortgages. But without more data on defaults or arrears, it’s hard to gauge how badly underwritten the loans were, and what the hit to the taxpayer could be. Some losses could be cushioned by deposit insurance, but don’t hold your breath for the small print.
