Copper and nickel are both lower today as traders reassess inventory trends, macro pressure, and supply-policy risks across the base-metals complex. Copper is pulling back as LME inventories rebuild after a recent supply squeeze, but the long-term demand story remains supported by AI data centers, electrification, power grids, and possible U.S. tariff-driven stockpiling. Nickel is also weaker as improved Indonesian supply expectations, RKAB quota policy, and softer stainless steel sentiment continue to weigh on prices.
Today’s pricing snapshot
According to Trading Economics CFD benchmarks, copper traded around $6.48/lb on August 20, 2026, down roughly 0.10% on the day. Copper is down about 0.46% over the past month, but remains up roughly 45.93% year over year. Trading Economics also notes that copper reached an all-time high of about $6.83/lb in August 2026.
Nickel traded around $16,945/metric ton on August 20, 2026, down roughly 1.08% on the day. Nickel is down about 0.91% over the past month, but remains up roughly 13.34% year over year, showing that the longer-term trend remains positive even though near-term momentum has weakened.
5 key drivers behind today’s move
1) Copper is slipping as inventories rebuild
Copper is lower today as more metal moves back into LME warehouses. Reuters reported that LME copper inventories rose again, bringing the weekly gain to about 17%.
That matters because copper recently rallied on worries about low inventories. When warehouse stocks begin rebuilding, traders can take some pressure out of the market and lock in profits after a strong run.
2) Copper is still supported by a long-term supply squeeze
Even with today’s decline, copper remains near historically elevated levels. The bigger copper story is still about limited supply growth, declining ore grades, mine disruptions, long project timelines, and producer challenges in major mining regions.
Copper supply cannot be increased quickly. New mines can take years to permit, finance, build, and ramp up, so the market remains sensitive to disruptions even when short-term inventories rise.
3) AI and data-center demand remain major copper catalysts
Copper’s long-term demand story remains tied to AI infrastructure, data centers, power networks, cabling, grid upgrades, EVs, renewable energy, and broader electrification.
Data centers require major electrical infrastructure, and copper is essential for wiring, power distribution, cooling systems, and grid connections. That is why copper continues to trade like a strategic infrastructure metal, not just a traditional construction commodity.
4) U.S. tariff uncertainty is still shaping copper flows
Possible U.S. copper tariffs remain a major market wildcard. Tariff expectations can encourage stockpiling, redirect metal into U.S. warehouses, and create regional supply-chain pressure.
That keeps copper volatile. Even when prices fall on inventory builds, traders are still watching whether trade policy changes could tighten U.S. supply or affect global copper flows.
5) Nickel is lower as Indonesian supply expectations weigh on sentiment
Nickel is weaker today as traders continue to focus on Indonesia, the biggest supply-side driver in the global nickel market. Expectations of improved Indonesian ore availability and possible RKAB quota relaxation continue to pressure sentiment.
At the same time, Indonesia’s quota system still provides some support because it limits oversupply risk. That creates a two-sided setup: more quota approvals could pressure nickel, while continued supply discipline could limit downside.
What to watch next
Copper traders will be watching LME and COMEX inventories, U.S. copper tariff developments, China industrial demand, DRC concentrate restrictions, mine-supply updates from Chile, Peru, Indonesia, and the Democratic Republic of Congo, AI/data-center power demand, grid investment, EV sales, U.S. dollar moves, Treasury yields, and broader risk sentiment.
Nickel traders will be watching Indonesia’s RKAB quota process, supplementary quota approvals, stainless steel demand, EV battery demand, Class 1 nickel premiums, LME inventories, Indonesian export rules, ore shipments, sulfur costs, and whether supply discipline continues through the second half of 2026.
Bottom line
On August 20, 2026, copper and nickel are both lower. Copper is easing as inventories rebuild and traders take profits, but its long-term setup remains supported by AI/data-center demand, electrification, power-grid investment, tariff uncertainty, and tight mine supply. Nickel is also weaker as improved Indonesian supply expectations and RKAB quota headlines weigh on sentiment.
Copper remains the cleaner long-term structural-demand story, while nickel remains the more supply-policy-sensitive trade today.
