LONDON (Reuters) - The U.S. dollar edged higher for a second consecutive day on Tuesday as traders worried about rising tensions between the United States and China, while the Australian dollar gained thanks to a bounce in oil prices.
But the dollar's gains were marginal as risk sentiment improved slightly on further easing of lockdown measures, raising hopes the global economy is likely to be close to or just past the worst of the sharp downturn.
"Investors have turned their gaze back to the easing of the 'stay at home' measures ... with the slowdown in both infected cases and deaths helping sentiment," said Charalambos Pissouros, a senior market analyst at JFD Group.
Against a basket of its rivals (=USD), the dollar edged up 0.1% to 99.55, and was not far away from a near two-week high of 100.83 in late April.
The dollar strengthened after U.S. President Donald Trump stepped up verbal attacks on China ahead of a Nov. 3 presidential election, raising fears of a new trade war.

Public holidays in Japan and China lightened trade; the yuan

U.S. crude rose (CLc1) 6.6% and Brent (LCOc1) around 5% as production fell and countries around the globe including Italy, Finland and several U.S. states eased lockdown restrictions.
Elsewhere, the euro slipped 0.1% to $1.0892, hit by a court challenge from German academics to the European Central Bank's bond buying programme.
A ruling is due later on Tuesday and while an outright rejection of the German Bundesbank's participation in the asset purchases appears unlikely, anything less than a clear-cut defeat of the challenge could hit the single currency.
