Jan 30 (Reuters) - Most emerging market currencies and stocks fell on Friday, after U.S. President Donald Trump firmed his pick for the next Federal Reserve chair, while a decline commodity prices added further pressure on some equities.

Trump said he would name Fed Chair Jerome Powell's successor on Friday. A person familiar with the matter said Kevin Warsh had visited the White House on Thursday, while Bloomberg News reported that the former Fed governor would get the nod.

Markets anticipate Warsh to bring a slightly hawkish tilt to the central bank, and the news supported the dollar index =USD on Friday, strengthening against most emerging market currencies.

"Trump's first selection criterion is whether the candidates are willing to pursue lower interest rates. So, if he does nominate Warsh later today, he (Warsh) is unlikely to be as hawkish as he once was," said Bas van Geffen, senior market strategist at Rabobank.

"The market may respond optimistically to the prospect of Warsh's nomination, but broader U.S. policy uncertainty is still not doing the dollar any favours."
