FRANKFURT (Reuters) - Donald Trump's victory in the race to become the next U.S. president will, if confirmed, have economic consequences for the rest of the world that are likely to be deep and quite immediate.

As congratulations poured in from world leaders, Trump claimed on Wednesday he had been given a "powerful mandate" to rule.

If he enacts just a fraction of his pledges - from higher trade tariffs to deregulation, more oil drilling and more demands on America's NATO partners - the strain on government finances, inflation, economic growth and interest rates will be felt in every corner of the world.

Trump's Republican Party also secured the Senate and was making gains in the House of Representatives, potentially making it easier for the president to legislate his proposals and push through key appointments.

"Trump's fiscal pledges are seriously troublesome – for the U.S. economy and for global financial markets – as they promise to vastly expand an already excessive deficit at the same time as he threatens to undermine key institutions," Erik Nielsen, UniCredit's Group Chief Economics Advisor, said.

"One must conclude that Trump poses a serious – and so far vastly under-appreciated - threat to the U.S. Treasury market and thereby to global financial stability," Nielsen said.

Import duties, including a 10% universal tariff on imports from all foreign countries and a 60% tariff on imports from China, are a key plank of Trump's policies and likely to have the biggest global impact.

Tariffs inhibit global trade, lower growth for exporters, and weigh on public finances for all parties involved. They are likely to raise inflation in the United States, forcing the U.S. Federal Reserve to act with tighter monetary policy.

The International Monetary Fund has already characterised global growth as weak, with most nations producing "feeble" expansion. A further hit to global trade is likely to present a downside risk to its 3.2% GDP growth projection for next year.

Firms mostly pass import costs onto the customer, so tariffs are likely to be inflationary for U.S. buyers, forcing the Fed to keep interest rates high for longer or to even reverse course and hike borrowing costs once again.

This will be even more likely if Trump keeps his spending and tax pledges, which could increase the U.S. debt by $7.75 trillion through 2035, according to the non-partisan Committee for a Responsible Federal Budget.

"Higher inflation would weigh on domestic demand, especially as it would call for a restrictive monetary policy response, with a negative impact on growth," Anis Bensaidani at BNP Paribas said.
