Will Black Sea Attacks Rattle Global Commodity Flows?

Will Black Sea Attacks Rattle Global Commodity Flows?

Arlan Suderman, StoneX Chief Commodity Economist, surveys the week’s critical flashpoints from the trading floor, weighing how geopolitics and policy could redirect global flows of grain, energy and protein.

 

Key Takeaways

  • A successful strike on the Kerch Bridge could disrupt up to 30% of Russia’s wheat exports and 1.5 m bbl/day of crude
  • U.S.–China negotiations may reopen consumer-goods trade in exchange for larger U.S. commodity purchases
  • Pending U.S. biofuel decisions will determine future demand for soy oil, canola and corn-based ethanol

Black Sea Tensions Threaten Grain and Energy Routes

“Ukraine does have an interest in bringing down at least a portion of that bridge”, Suderman notes, referring to last week’s bombing of pillars on the Kerch span. If the structure falls, clearance work “could be at risk here is 30% of Russia’s wheat exports… and 1 ½ million barrels per day of crude oil”. With Russia’s harvest season approaching, even a temporary channel closure could jolt wheat and crude benchmarks, already nudging fund managers to cover shorts and push WTI toward two-month highs near $65.

Trade War Maneuvers and Rare-Earth Leverage

Suderman notes that China “built its economy and its military war machine based in part on trade surpluses”, once shipping $450 bn of goods annually to the U.S. The May 11 “90-day pause” reopened dialogue, and Beijing has since issued rare-earth export licenses after pressure from Washington. As negotiators meet in London, Suderman sees scope for a framework granting China “favorable access to our consumer market… in exchange for buying our commodities”, though full resolution “could take months… if not years”.

The Three Moving Parts of Biofuel Policy

Domestic edible-oil demand hangs on the Environmental Protection Agency’s imminent rulings. First, updated Renewable Volume Obligations have cleared agency review and await White House release within “the next week to 10 days”. Second, small-refinery exemption decisions for 2024—and a backlog stretching to 2016—could offset those volumes. Third, the financing mechanism, Section 45Z, passed the House in the “big beautiful tax bill” but remains uncertain in the Senate. Removing the indirect land-use penalty would be “very positive not only for soy oil demand… but for ethanol demand”.

Protein Markets Defy High Prices

Cattle inventories remain “very low… due to a multi-year drought in the west”. Early herd rebuilding is “tightening our supplies even more”, while cheap feed has pushed carcass weights to records. Imports help but fail to meet demand, as consumer diets shift toward protein under the influence of GLP-1 drugs. Despite record cash cattle prices, “we’re seeing a resiliency of demand”, sustaining historically high beef valuations and reinforcing protein’s status as one of the year’s strongest commodity performers.

Perspective: Morning Commentary for August 7

August 7 – The U.S. economy unexpectedly lost 23k jobs in July, dramatically below market expectations of an 80k increase and marking the worst Non-Farm Payrolls print since February. Furthermore, May and June were both revised sharply downward, with combined revisions showing 103k fewer jobs than previously reported. Outside of the healthcare sector, which added 22k jobs in July, the losses were very broad-based. Government payrolls saw the largest decline, shedding 53k jobs in July, the largest seen since October 2025, while June was revised down to show a loss of 10k jobs as well. The private sector at least saw growth, adding 30k jobs in July, now matching the month prior after it was revised down from the 49k initially reported, and substantially missing forecasts of 78k jobs being added. This is a sharp reversal in course from the largely better than expected U.S. labor data seen earlier this week.
