Freight Cost as a Percentage of Trading Margin: The Calculation That Changes Procurement Decisions

The difference between these framings is not cosmetic. It determines whether freight optimization sits in operations or on the CFO's agenda.

Why the standard metric understates the problem

A trading desk with $50M annual revenue and $4M freight spend reports freight at 8% of revenue. That number lives on the P&L as a cost line, managed by the logistics team, reviewed quarterly.

The same desk running a typical thermal coal arbitrage — buying Indonesian 4200 GAR at $55/t FOB Kalimantan, selling at $65/t CFR India, freight cost $8/t — has gross commodity spread of $10/t and freight representing 80% of that spread. After freight, the raw margin before all other costs is $2/t.

In this framing, a 15% coordination premium in freight procurement — $1.20/t — does not consume 8% of revenue. It consumes 60% of the remaining margin after freight.

This calculation should be on the CFO's desk.

The margin structure of commodity trading

To run this correctly, it is worth being precise about what “margin” means in commodity trading.

The gross commodity spread — sale price minus purchase price — is not the full picture. Commodity traders earn margin from multiple sources: price arbitrage, quality arbitrage (buying lower grade, blending, selling higher grade), timing arbitrage (storage and carry), location arbitrage (route optimization), and service value (reliability, credit terms, logistics management).

Freight cost sits against all of these margin sources simultaneously. A trade that looks thin on pure price spread may be profitable when timing and quality elements are included. The relevant calculation is freight as a percentage of total transaction margin — not just price spread.

That said, on competitive commodity routes in 2025–2026, total transaction margins for many standard thermal coal and iron ore trades are in the $3–8/t range after all costs. Freight costs of $8–25/t on those same routes mean freight routinely represents 200–400% of gross commodity spread, with profitability dependent entirely on the non-price margin elements.

Route-by-route analysis: where freight hits hardest

Using current market data (Q1 2026), here is how freight sits against gross price spreads on major commodity routes:

Indonesian thermal coal (4200 GAR) — Kalimantan to India:

• FOB Kalimantan: ~$55/t
• CFR India East Coast: ~$63/t
• Gross spread: $8/t
• Panamax freight cost: ~$7–9/t
• Freight as % of gross spread: 87–112%

This is the archetypal thin-margin route. The trade is viable because of credit terms, volume relationships, and logistics management value — not because the price spread covers freight comfortably.

Australian thermal coal (6000 NAR) — Newcastle to Japan:

• FOB Newcastle: ~$108/t
• CFR Japan: ~$115/t
• Gross spread: $7/t
• Panamax freight cost: ~$12–15/t
• Freight as % of gross spread: 171–214%

The spread does not cover freight. Profitability depends on quality premium, long-term supply agreement value, and other elements. A $1.80/t freight saving (15% on $12/t) adds 26% to the gross price spread.

Australian premium HCC — Dalrymple Bay to China:

• FOB Dalrymple Bay: ~$190/t
• CFR China: ~$205/t
• Gross spread: $15/t
• Panamax freight cost: ~$14–18/t
• Freight as % of gross spread: 93–120%

Coking coal has wider margins than thermal in absolute terms, but freight is also higher and the spread is still thin relative to freight.

Iron ore (62% Fe) — Port Hedland to Qingdao:

• CFR Qingdao: ~$105/t
• FOB Port Hedland: ~$93/t (implied)
• Gross spread: ~$12/t
• Capesize freight cost: ~$9–13/t
• Freight as % of gross spread: 75–108%

What a 15% freight improvement means per tonne

The 15% average rate reduction from closed-bid versus email tendering is not a large percentage in isolation. Applied to freight costs, then expressed as percentage of transaction margin, it produces numbers that are material:

Route	Freight cost	15% saving	Gross spread	Saving as % of spread
Kalimantan–India	$8/t	$1.20/t	$8/t	15%
Newcastle–Japan	$13/t	$1.95/t	$7/t	28%
Dalrymple Bay–China (HCC)	$16/t	$2.40/t	$15/t	16%
Port Hedland–Qingdao	$11/t	$1.65/t	$12/t	14%

On a desk running 1.5 million tonnes annually across these routes — modest for a mid-tier commodity trading house — the aggregate freight optimization at 15% improvement is $2–3M per year. That is before accounting for demurrage reduction.

The calculation that belongs on the CFO's desk

Most commodity trading companies have the data to run this analysis. The inputs are: awarded freight rates per fixture, Baltic Exchange route indices on the same dates, transaction P&L by route, and annual volume per route.

The output is two numbers: current freight premium above market rates (estimated), and that premium expressed as a percentage of transaction margin by route.

For most desks running competitive routes, the freight premium from email tendering represents 15–30% of total transaction margin on those routes. That is not an operations metric. It is a CFO metric.

The conversation that follows is straightforward: the cost of closing the procurement gap is recoverable in weeks. The question is not whether to act — it is why it has not happened already.
