Why Headline Spreads Vanish: The Landed-Cost Reality Check

The Spread Mirage

A trader spots copper at $8,500/tonne in Singapore and $9,500/tonne in Rotterdam. That's an 11.8% headline spread. On a 100-tonne shipment, it's $100,000 in gross margin. Then reality arrives.

Landed cost is the true arbiter of arbitrage viability. It is the all-in price of the commodity at its destination, including every friction cost between origin and final buyer. Missing this calculation is how traders lose money on seemingly profitable corridors.

The Cost Stack

Start with the commodity price at origin. Add:

• Ocean freight: $45–65/tonne for containerised metal, $20–35/tonne for bulk. Volatile and non-negotiable.
• Insurance: 0.5–1.5% of value depending on route risk and commodity.
• Port handling: Loading, documentation, terminal fees at origin and destination. Often $8–15/tonne combined.
• Inspection and certification: SGS, Bureau Veritas, or local assay. $300–800 per shipment, or $3–8/tonne on smaller lots.
• Import duty: 0–15% depending on commodity, destination, and origin trade agreements. Tariffs can swing a corridor overnight.
• VAT/GST: Recoverable in some markets, not others. Material in Europe and Asia.
• Financing cost: If funding the trade for 30–45 days, add 4–8% annualised cost on working capital.
• FX slippage: Spot-to-forward basis, conversion fees, and timing mismatches between payment and delivery.

The Math That Matters

On that copper example: $100,000 headline margin minus $6,500 freight, $1,200 insurance, $1,500 port costs, $500 inspection, $12,000 import duty (12%), $2,000 financing, and $1,300 FX friction leaves $75,000 gross. But operational overhead, compliance, and logistics risk eat another 5–10%. The viable margin is now 3–5%, not 12%.

Smaller shipments worsen the ratio. A 10-tonne container has the same inspection and documentation cost as 100 tonnes, compressing per-unit margin by an order of magnitude.

Timing and Execution Risk

Landed cost is not static. Freight rates move daily. Duty classifications are subject to audit. Inspection delays add financing cost. FX forwards lock in conversion rates but introduce counterparty risk. A trader who quotes a buyer without locking these costs first is speculating, not arbitraging.

Professional traders build landed-cost models before committing capital. They negotiate freight and insurance early, confirm duty classification with customs brokers, and stress-test margins against 10–15% adverse moves in freight or FX. The headline spread is a starting point, not a conclusion.

The Discipline

Arbitrage is a discipline of precision. Every cost layer must be quantified, confirmed, and monitored. The traders who survive are those who treat landed cost not as an afterthought but as the foundation of deal structure.
