MILAN/SYDNEY: World shares dipped on Monday as the US Senate's passage of a $1.9 trillion stimulus bill put fresh pressure on Treasuries and tech stocks with lofty valuations, raising inflation jitters.

BofA analyst Athanasios Vamvakidis argued the potent mix of US stimulus, faster reopening and greater consumer firepower was a clear positive for the dollar.
"Including the current proposed stimulus package and further upside from a second-half infrastructure bill, total US fiscal support is six times greater than the EU recovery fund," he said. "The Fed is also supportive with US money supply growing two times faster than the Eurozone."
