A legal claim filed by Mercuria Energy Group Ltd., one of the world's largest oil traders, has dragged the 282-year-old Baltic Exchange — and the multibillion-dollar tanker freight market it anchors — into the London High Court. As Bloomberg reported on April 30, Mercuria alleges hundreds of millions of dollars of losses from distortions in a key benchmark for the cost of shipping crude from the Middle East to China. The case is one of the first major legal expressions of the disruption that the near-closure of the Strait of Hormuz has unleashed across oil and shipping markets, and lawyers expect a wave of similar disputes to follow.
At the heart of the dispute is the TD3C rate, calculated daily from broker assessments collected by the Baltic Exchange. For years TD3C has been priced off shipments departing Saudi Arabia's Ras Tanura port — inside the Persian Gulf and accessible only via Hormuz — and used as the global tanker benchmark and the underlying for a huge derivatives market. In March the Baltic Exchange, owned by Singapore Exchange Ltd., told brokers TD3C should still be calculated on the Ras Tanura route even though shipments had "all but ceased". TD3C subsequently soared from a typical $40,000-$100,000 a day to as much as $600,000. Norway's Hunter Group ASA later disclosed that a customer — Mercuria, per a person familiar — had paid it $8.3 million less than due for March charters tied to the index.
Mercuria is asking the court to either suspend TD3C or determine it from economically comparable routes still operating — for example shipments from Omani ports outside the Gulf to China, or West Africa to China — and to apply that determination retrospectively for periods Mercuria says were "improperly determined". The trading house has not put a monetary value on the claim, asking only for "such further or other declaratory relief as the court considers appropriate", while warning of "very significant future losses" on top of present damages. Singapore Exchange responded on May 3 that the Baltic Exchange produces benchmarks under "established and robust governance frameworks" and called the claim "without merit", pledging to defend it to the fullest extent.
For the wider supply chain and commodity finance world, three lessons emerge. First, indices freezing in a crisis is a recurring failure mode: the 2008 credit crunch and the 2022 LME nickel blow-up showed how derivative books unravel when benchmarks lag market reality. Second, Mercuria's framing of the "cascading effect" beyond physical molecules captures how a Hormuz disruption now ripples through the entire TD3C-linked derivatives stack. Third, when the Baltic Exchange consulted members last week, 55% opposed any change to TD3C — citing continuity for those who took positions on the March guidance — a stance that runs head-on into Mercuria's argument that the index no longer represents the market it is meant to measure. Practitioners warn the nickel-style litigation wave may now be coming for tanker indices.
Key Takeaways:
1. Mercuria Energy Group sued the 282-year-old Baltic Exchange at London's High Court over distortions in the TD3C tanker benchmark, alleging hundreds of millions of dollars of losses.
2. TD3C is priced off Saudi Arabia's Ras Tanura port, but Hormuz disruption halted shipments; the rate spiked from $40,000-$100,000/day to as much as $600,000.
3. Norway's Hunter Group ASA reported $8.3 million in shortfalls on March charters; the customer was identified as Mercuria.
4. Singapore Exchange rejected the claim; in a Baltic Exchange consultation, 55% of members opposed any change to TD3C.
5. Lawyers expect a fresh wave of index and derivatives litigation echoing the 2008 crisis and the 2022 LME nickel blow-up.
