Asian shares rebounded on Thursday and the dollar firmed in a remarkable snapback from the shock of Republican Donald Trump's presidential victory, though the speed of the reversal left some market watchers scratching their heads.

He noted that a key market barometer of 10-year inflation expectations had jumped to a 16-month peak of 1.87 percent.

The dollar carved out a staggering range, rebounding along with the surge in U.S. yields from as low as 101.19 yen all the way to 105.96 early on Thursday.

The dollar index against major currencies recovered from a trough of 95.885 plumbed on Wednesday to around 98.448.

Having stretched as high as $1.1300 in the initial panic over Trump's win, the euro then slumped all the way to $1.0906 overnight - a move of roughly four cents.

The longer-term outlook for the dollar's weakening peers remained unclear, however.

"We expect a Trump Treasury to elevate the importance of the bilateral trade surplus with the U.S. in identifying currency manipulators and intensify pressure on trade partners to allow currencies to appreciate," Tim Condon, an Singapore-based economist at ING, said in a report.

"Further out, Trump's protectionist policies may prove another big step back in the gradual unwinding of goods globalization that has defined the past 30 years," wrote analysts at Nomura.

"Another important factor is that a Trump presidency would bring with it uncertainty that could undermine the Pax Americana, with all the benefits this has brought to the world in general and, perhaps, Asia in particular since 1945."

For now, investors seemed willing to give the president-elect the benefit of the doubt, as witnessed by a broad advance in bulk commodity prices.
