The Mansion House dinner in the City of London is one of Britain’s big set-pieces of the year featuring speeches by Bank of England Governor Mark Carney and finance minister George Osborne.

Carney will be speaking a week before the Bank’s Financial Policy Committee meets and is expected to road test its new tools to calm the housing market. Among other measures, the BoE could recommend caps on the size of home loans granted in relation to a property’s value or a borrower’s salary.

There have been some signs of demand for mortgages slowing of late but London – the real hotspot – is being fuelled by an influx of foreign money which does not require a home loan to buy. The FPC could also suggest the government curbs its “Help to Buy” scheme which helps Britons get on the property ladder.

The International Monetary Fund has urged Britain to rein in risky mortgages to avert the risk of a property bubble. The latest housing survey from the Royal Institution of Chartered Surveyors, released overnight, showed house prices rose faster than expected in May but are expected to increase less over the next year as tighter lending conditions and concerns about the market weigh on demand.

Bank of England policymaker Ben Broadbent said yesterday that the housing market posed the greatest threat to Britain’s financial stability but that it so far bore little resemblance to debt-fuelled booms of the past.
