Asia has been hit disproportionately hard, the bank will say, in a report that warns of many Asian stimulus plans lagging behind those of the leading global economies.
Separately, the World Bank said yesterday that developing countries faced a financing gap of between $270bn and $700bn a year as capital flows dried up, with only a quarter of vulnerable countries able to cushion the blow of the economic downturn.
The ADB report estimates capital losses last year in Asia, excluding Japan, at $9,625bn, or 109 per cent of gross domestic product, compared with a global average of 80-85 per cent of GDP. For Latin America, the study estimates 2008 losses at $2,119bn, or 57 per cent of GDP.
