NEW DELHI, March 10 (Reuters) - London copper prices edged lower on Monday as traders assessed uncertainties surrounding U.S. tariff policies, although a weaker dollar helped limit the downside.
Three-month copper on the London Metal Exchange (LME) CMCU3 fell 0.6% to $9,552 a metric ton as of 0740 GMT.
The most-active copper contract on the Shanghai Futures Exchange SCFcv1 shed 0.6% to 78,270 yuan ($10,779.80) a ton.
U.S. President Donald Trump in an interview on Sunday declined to predict whether the U.S. could face a recession amid stock market concerns about his tariff actions on Mexico, Canada and China over fentanyl.
Trump's trade policies have fuelled fears of a trade war, which could dampen economic growth and raise prices for Americans still reeling from years of high inflation.
"Dramatic shifts in U.S. trade and foreign policy are likely to cause further disruption to metal markets," ANZ Research said.
"President Trump has placed a 25% tariff on U.S. aluminium and steel imports. A levy on copper is also on the cards. The short-term impact will be a rise in premiums as the U.S. struggles to adjust to the dislocation in physical markets."
The dollar, softer on Monday and trading near its lowest level in four months against major currencies, helped cushion the fall, as concerns over a global trade war led investors to safe havens, lifting the yen and the Swiss franc. USD/
