London Commodity News 4th June 2026
Commodity markets remained heavily driven by supply security concerns and geopolitical developments, with energy markets continuing to react sharply to every shift in Middle East negotiations. While oil markets softened on renewed diplomatic optimism, tighter physical balances across coal supply chains continued to provide support for thermal coal markets.

Coal
The volatile, yo-yo behaviour across coal markets continued today, with yesterday’s strength giving way to weaker pricing across much of the forward curve as lower oil prices and renewed optimism surrounding potential peace negotiations weighed on sentiment once again.
Despite weakness further forward, Newcastle physical markets remained notably active. Strong buying interest saw July physical trade up to $150/t, helping prompt NEWC swaps rally despite broader weakness across forward markets. August physical activity also remained firm, with multiple trades reported around the $149/t level.
Underlying coal market fundamentals remain relatively supportive, with tightening export supply conditions continuing to offset broader macro uncertainty.
In Colombia, the blockade affecting Cerrejón’s rail corridor entered its ninth consecutive day, continuing to disrupt mining, rail and export operations at one of the Atlantic Basin’s largest thermal coal supply systems. The disruption adds further supply-side risk and reinforces concerns surrounding logistics reliability across key export corridors.
European supply balances also remain influenced by growing inventories and constrained inland logistics. Coal inventories across the Amsterdam-Rotterdam-Antwerp (ARA) hub rose by 42,000t during the week to 31 May to reach 3.74mn t, while inventories at Rotterdam’s EMO terminal increased to 2.5mn t. However, low Rhine river levels continue restricting downstream deliveries, limiting the ability for inventories to move efficiently through the supply chain.
In South Africa, logistical risks remain firmly in focus following a derailment on the Transnet coal export corridor servicing Richards Bay. Although partial operations resumed relatively quickly, the incident again highlighted ongoing infrastructure vulnerabilities ahead of Transnet’s scheduled maintenance programme later this summer.
Despite these operational challenges, RBCT inventories remained above the 4mn t threshold for a third consecutive week. Export demand remained robust, particularly from India, which continued to dominate South African export flows.
European thermal coal markets continue receiving support from tightening physical conditions, with Argus NAR 6,000 kcal/kg CIF ARA rising above $140/t for the first time since late 2023 as Colombian supply risks, South African logistical concerns, uncertainty surrounding US-Iran negotiations and broader gas market concerns continue supporting sentiment.
Brent Crude
Brent crude extended recent losses, falling more than 3% toward $94/bbl as optimism surrounding potential diplomatic progress between Washington and Tehran improved market sentiment.
Markets reacted positively following reports that Israel and Lebanon had moved closer toward a ceasefire agreement, while comments from President Trump suggesting progress in negotiations with Iran could emerge within days added further downside pressure to prices.
However, significant uncertainty remains. Iranian officials continued denying meaningful progress while Israeli leadership signalled military operations could continue. Recent exchanges between US and Iranian forces, alongside the widening regional spillover into Bahrain and Kuwait, continue to underline the fragile nature of current negotiations.
Despite improving sentiment, oil markets remain highly sensitive to conflicting headlines and uncertainty surrounding the eventual reopening of regional energy flows.
Iron Ore
Iron ore prices moved lower amid concerns surrounding increasing global supply growth and weaker market sentiment.
The most-traded DCE September contract closed down 1.85% at 767 yuan/mt while portside prices declined by 6–11 yuan/mt.
Market sentiment was weighed by expectations of growing exports from Guinea’s Simandou project alongside broader concerns regarding rising seaborne supply. However, elevated freight costs continue limiting downside pressure, while underlying steel production remains relatively supportive.
For now, markets continue balancing supportive demand conditions against increasingly abundant supply expectations.
Copper
Copper prices eased back below $14,000/mt as geopolitical uncertainty and macroeconomic concerns weighed on market sentiment.
Although long-term demand drivers remain supportive, markets are increasingly focused on near-term risks surrounding global growth, higher energy costs and potential changes to US trade policy.
Attention remains centred on an upcoming US decision regarding potential tariffs on refined copper imports. Market participants remain concerned that further tariff measures could accelerate stock movements into US warehouses and tighten availability elsewhere.
Despite recent price weakness, structural demand from electrification, renewable energy expansion, artificial intelligence infrastructure and data centre development continues to provide underlying support for longer-term market fundamentals.
Commodity markets continue balancing competing forces of tightening physical fundamentals, geopolitical uncertainty and shifting macroeconomic expectations. While energy markets remain highly sensitive to developments in the Middle East, supply disruptions and logistical constraints continue to provide underlying support across several key commodity markets.
