The Dow Jones Industrial Average index was down 47.22 points (0.14 per cent) at 32683.98.

Also, the Fed Chief praised the measures taken by Congress to support the economy and hoped for a return to more normal conditions later this year as the COVID-19 vaccination campaign expands.
The pressure on equity markets comes from, among other things, reports that the US has not ruled out that AstraZeneca (LON:AZN), which reported the previous day that its vaccine against severe forms of coronavirus was 100% effective in a study, may have published outdated and incomplete data on the trials.
