US Butane Exports Hit All-Time High in April: Kpler

Why It Matters

The record export level positions the United States as a critical alternative source of butane for Asia, reshaping global LPG trade flows and influencing pricing dynamics amid Middle‑East supply constraints.

Key Takeaways

• US butane exports reached 689,000 barrels per day in April
• India absorbed 247,000 tonnes, the largest single‑destination share
• Spot terminal fees rose 10¢/USG for split‑cargo loadings
• Inventories stayed 27.5% above year‑earlier levels
• Butane price share of WTI fell to 47.2% from 65.6%

Pulse Analysis

The United States logged an unprecedented surge in butane exports in April, moving 689,000 barrels per day—or roughly 1.9 million metric tonnes—according to data firm Kpler. The spike reflects a rapid shift in Asian buying patterns as the Middle East’s LPG output, traditionally split evenly between propane and butane, faced constraints from the Strait of Hormuz blockade. Buyers in India, China, Korea and Morocco turned to U.S. terminals, which are primarily configured for propane, to fill the shortfall, pushing U.S. butane to the forefront of global supply.

The export boom translated into higher terminal fees and tighter pricing. Spot fees for May and June split‑cargo loadings commanded a premium of at least 10 cents per US gallon over pure‑propane shipments, a clear signal of market stress. Yet U.S. butane inventories remained robust, sitting 27.5 % above the prior‑year level at 33.76 million barrels. Prices at Mont Belvieu rose 21.875 cents per gallon—a 23.6 % increase since the Iran‑Iraq conflict began—though they lagged crude’s rally due to ample stockpiles.

From a strategic standpoint, the record export level reshapes the U.S. LPG landscape. With a growing share of global butane demand now sourced from American terminals, domestic producers gain leverage in pricing negotiations and can diversify beyond traditional propane‑centric contracts. However, the declining contribution of butane to the WTI price basket—down to 47.2 % from 65.6 % a year earlier—suggests that while volumes are up, price power may be muted. Analysts will watch whether the Middle East supply squeeze persists, which could cement the U.S. as a long‑term butane hub.
