(Reuters) - Donald Trump's return to the White House after winning the Nov. 5 U.S. presidential election may reshape American business. Much depends on whom he appoints as deputies and cabinet members, including the role of Tesla CEO Elon Musk, and what tariffs he enacts. Following are some major issues and sectors to watch:

WHAT ROLE WILL ELON MUSK PLAY?

After some nudging from the world's wealthiest person, Trump has said he would tap Tesla CEO Elon Musk to lead a new government efficiency commission. Musk has said at least $2 trillion could be cut from the $6.75 trillion federal budget. How that works could be a key to the next Trump administration.

Does efficiency mean fewer rules and regulators? Musk has been a vocal critic, for instance, of federal review of his SpaceX rocket business. That could mean less oversight of self-driving cars (a Tesla business) or rocket launches and much more.

The two men are not completely in sync: Trump has said he won't let California require all vehicles in the state go electric in a decade, but Musk runs the world's most valuable EV company. "A rising tide raises all boats. So to the extent that Elon is able to hamper the vilification of EVs by a potential Trump administration, all the better," said James Chen, former head of policy for Rivian and Tesla. How Musk would address conflicts of interest between his interests in autos, space, health, construction and artificial intelligence is not clear.

Trump has pledged to be a "crypto president", a plan that may start with replacing industry opponent Gary Gensler, the Securities and Exchange Commission chair who has sued most of the industry – including Coinbase, Binance and Kraken. Gensler's replacement is expected to review - and potentially tear up - accounting guidance and create industry exemptions from SEC rules. Musk, too is a crypto supporter, as is Silicon Valley Trump supporter Marc Andreessen and incoming Vice President J.D. Vance.

Musk is also a big proponent of carbon-free energy, with Tesla being a major supplier of solar systems and batteries. Trump has promised to kill the offshore wind industry and rescind all unspent funds under the Inflation Reduction Act – Biden’s signature climate law. But Trump faces dissent in his ranks: Republican lawmakers, oil companies and others see massive red state gains from the law. Musk has played into that, building his second U.S. electric vehicle factory in Texas, for instance.

TARIFFS

Trump has proposed a 10% tariff on all U.S. imports and 60% on Chinese-made products, which if enacted would affect the whole economy by pushing consumer prices higher. The Tax Foundation, a non-partisan think tank, calculated Trump tariffs would hike taxes by $524 billion annually, shrink GDP by at least 0.8%, and cut employment by 684,000 full-time equivalent jobs potentially impacting retail workers, the largest private sector employer. He also suggested he might impose a 25% tariff on all imports from Mexico.
