The holiday from reality, for the happy few enjoying it, has been delightful. Three years ago it was still possible to fix a mortgage rate in Britain and much of the euro area at somewhere near 1%. American housing loans were dearer by just a percentage point or two.

Moreover, the inflation that prompted rates to rise has bitten chunks out of the real value of their debt.
