LME stock tightens up as copper prices rise, dollar falls

The dollar fell on Tuesday after Israel and Iran agreed to stop their attacks against each other. Meanwhile, visible metal inventories outside of the United States tightened further.

The benchmark three-month copper price on the London Metal Exchange increased 0.8% by 0951 GMT to $13,728 per metric ton, but was hampered by the 21-day moving median at $13,735. The U.S. Dollar Index was down by 0.2%. However, the markets are waiting for Wednesday's U.S. Inflation data to get clues about the Federal Reserve. Dollar-priced materials become more appealing to buyers who use other currencies when the U.S. dollar is weaker. COMEX copper contract prices are also higher than the LME benchmark, which is a result of the premium. This was done to support copper prices before the Department of Commerce made a possible recommendation on import tariffs. The premium is driving inflows into COMEX stocks in the U.S. while stocks available in LME-registered warehouses are not. According to the daily LME data they were at 228,650 tonnes, which is the lowest level since February 19. Analysts at Morgan Stanley expect that President Donald Trump will make a decision about U.S. import tariffs in the second half 2026 after receiving an update from domestic markets by June 30. A 15% tariff announced in advance for January 2027 will drive COMEX copper and LME spreads higher, and tighten LME margins. Morgan Stanley stated that if tariffs are not implemented, they would remove about 2.5% of global annualized copper demand from the U.S.

Analysts estimate that the U.S. has "over-imported" copper by 260,000 tons in the past year. The country holds over a year's worth of "normal" refined copper imports. Aluminium fell by 0.8% on the LME to $3,575.50, after having hit a low of $3.570.5 in three weeks, despite Iran and Israel agreeing to stop their attacks. Tehran continues to block shipping through the Strait of Hormuz. Zinc rose by 1.1% to $3575.50. Goldman Sachs stated that Boliden’s Garpenberg Mine could "structurally re-set to a lower?level of production for longer" after a seismic event in March. Lead dropped 0.1% to $1987. Nickel was down 0.6% to $18,230. Tin rose 1.4% to $50,880. Nickel and lead hit their lowest levels since May 21 and respectively April 23 earlier in the session.
