WASHINGTON, March 11 (Reuters) - Donald Trump laid out some of his financial priorities on Monday and defended his planned 10% across-the-board tariffs, saying any resulting price increase for families could be offset by tax cuts and calling for his 2017 tax cuts to be extended.

The Republican U.S. presidential candidate, speaking in an interview on CNBC, also called for action on popular U.S. entitlement programs, including cuts, and indicated he was not likely to curb use of cryptocurrencies.

Asked about concerns over increased political polarization on the nation's financial stability, Trump said he was concerned about

Fitch's 2023 downgrade

but dismissed the credit rating downgrade's ties to the Jan. 6 riot at the U.S. Capitol.

Trump's comments are his first extended remarks on his economic plans since he became the party's likely nominee following last week's "Super Tuesday" primary elections,

setting up a rematch

with Democratic President Joe Biden in November.

His tariff plan has spurred

talk of inflation

, and U.S. Treasury Secretary Janet Yellen has said it would

raise

costs for American consumers.

"I think taxes could be cut, I think other things could happen to more than adjust that. But I'm a big believer in tariffs," Trump told CNBC, saying they help American industries when they are "being taken advantage of" by China and other nations.

"Beyond the economics, it gives you power in dealing with other countries," he said, adding that he was not concerned about any possible retaliatory tariffs if he were to regain the White House.

Asked about Medicare, Social Security and Medicare programs and the nation's spending and deficits, Trump told CNBC: "There is a lot you can do in terms of entitlements in terms of cutting and in terms of also the theft and the bad management."

On bitcoin and other cryptocurrencies, Trump said he has "seen that there has been a lot of use of that. And I'm not sure that I'd want to take it away." (Reporting by Susan Heavey Editing by Bernadette Baum and Chizu Nomiyama)
