stocks tracked a decline in equities worldwide and oil was sold off on Monday as rare protests in major Chinese cities against the country's strict zero-COVID curbs fuelled concerns about global economic growth.

A surge in COVID cases and clashes between police and protesters across several major Chinese cities over the weekend also helped push U.S.

In currencies, the safe-haven Swiss franc and Japanese yen gained, while the Aussie dollar and Chinese yuan underperformed.

The dollar move had some market analysts blaming falling U.S.

The dollar index fell 0.292%, with the euro up 0.13% to $1.0409.

The dollar was down 0.4% against the Swiss franc after earlier falling as much as 0.77%.

In Treasuries Benchmark 10-year notes were down 2.8 basis points to 3.674%, from 3.702% late on Friday.

The 30-year bond was last down 2.7 basis points to yield 3.725%, from 3.752%, while the 2-year note was down 3.9 basis points to yield 4.4402%.

The worries about China's COVID policies overshadowed any support from the Chinese central bank's 25 basis point cut to the reserve requirement ratio (RRR) announced on Friday, which would free about $70 billion to prop up a faltering economy.
