LONDON, March 9 (Reuters) - Metals recovered after sliding earlier on Friday, lifted by upbeat U.S. wage data that dented the dollar and soothed inflation worries, although gains were capped by ongoing concerns that new U.S. tariffs would stoke a trade war.
The dollar fell versus a currency basket and equities rose after data showed strong job additions in February but muted wage growth, indicating a gradual rise in inflation and helping temper expectations of faster interest rate increases.
However, concerns remained about U.S. President Donald Trump's decision to impose a 25 percent import tariff on steel and 10 percent on aluminium, with initial exemptions for Canada and Mexico. The move takes effect within 15 days.
China said it "resolutely opposed" the tariffs and that they would "seriously impact the normal order of international trade", while the EU said it would go to the World Trade Organization to impose its own measures if hit by the tariffs.
"The impact of tariffs on metals markets is small, (as is) the impact of the tariffs in terms of U.S. or global GDP. But if the tariffs spark an acceleration in trade restrictions and shave 1 or 2 percent off global GDP, that's when they become very problematic," said Bernstein analyst Paul Gait.
International Monetary Fund Managing Director Christine Lagarde said she feared a "tit-for-tat" escalation of trade retaliation that would hurt business confidence and investment.
