Government bonds and the dollar firmed after the Shanghai composite index <
> slid 4 percent to a two-month closing low on disappointment that authorities were not taking steps to support the market amid heavy losses. It has fallen 20 percent since two weeks ago, rattling global markets.The S&P 500 futures index <SPc1> was down 0.9 percent while European shares <

They came slightly off session lows after data showed U.S. mortgage applications rose for the third week running last week, boding well for the hard-hit U.S. housing market.

"The fact that the declines in the Shanghai index are happening at the same time as G7 equities are falling is detrimental to risk appetite," CMC Markets analyst Ashraf Laidi said.
"Because there are no major figures in the U.S. there is very little that could alter this negative tone in risk appetite."
Oil and metal prices and cyclical currencies like the Australian dollar also fell as the sell-off in China gathered pace.

British gilts got an extra lift but sterling fell broadly after minutes from the Bank of England's August meeting showed the Monetary Policy Committee was split over whether to up the amount of gilt purchases it makes by even more than it did.
