(Reuters) - Goldman Sachs ( GS ) on Monday said the copper market is pricing in odds of about 50% that there will be a 10% U.S. tariff on the metal by the end of the first quarter of this year.

Analysts at the U.S. investment bank said in a client note that the estimate is similar to their own 50% subjective probability of a 10% effective tariff on copper by year-end.

Goldman also noted that the oil market is pricing in a nearly 40% chance of a 25% U.S. tariff on Canadian goods including oil, versus the bank's 15% subjective probability of a 25% effective tariff by the end of the year.
