Alasdair MacLeod: Contraction of Bank Credit Threatens Vicious Cycle

``The recent sharp fall in equity markets is leading to two levels of contraction of bank credit. Brokers' loans to speculating investors are being unwound from record levels, notably in China and also in the US where in July they hit an all-time record of $487bn. Then there is the secondary effect, likely to kick in if there are further falls in equity prices, when equities held as loan collateral are liquidated. This is when falling stock prices can be so destructive of bank credit, and as the US economist Irving Fisher warned in 1933, a wider cycle of collateral liquidation can ensue leading to economic depression.''
