Some of the world’s biggest banks are trying to extend the principles of securitisation to the plain-vanilla world of trade finance – a market worth an estimated $10tn a year – as concern mounts that regulatory changes could constrain a key lubricant of the global economy.

JPMorgan is among several banks that have begun testing investor appetite for the trade finance equivalent of collateralised debt obligations – the derivative products blamed for compounding the financial crisis – in an attempt to boost lending capacity.

Trade finance supports more than 80 per cent of global trade. But it has been disrupted by the financial crisis, as some lenders got into trouble, and by the regulatory response to the crisis, as banks have been ordered to hold more capital against lending.
