Freight & charter capacity

Transport capacity is the purest perishable good in commerce: a vessel open in a port on Tuesday, or a truck running back empty, is worth something on Monday and nothing on Wednesday. It is also priced almost entirely by conversation, against indices built from what brokers believe the market to be rather than from what it actually did.

01 · How this market works today

A perishable good, priced by whoever picks up the phone in time.

Chartering works, at scale, and has done for a very long time. It also concentrates almost all of the market's information in the brokers who sit between the two sides, which is fine until you are the party that does not have three of them on speed dial.

The index is an assessment, not a print

Freight benchmarks are built from panel submissions: brokers reporting where they believe the market sits for a notional voyage. They are carefully constructed and genuinely useful, and they are not transaction prices. Nobody can point to the trade that made the number.

Every fixture is bespoke, so nothing is comparable

Vessel class, laycan window, route, cargo, demurrage rate, bunker clause and off-hire terms are negotiated per fixture. Two fixtures at the same headline rate can be materially different deals, which makes the rate almost useless as a reference for the third.

Capacity expires while the price is being discovered

A broker ringing round to place an open vessel is racing a clock that ends in a ballast leg. The urgency is real and it is asymmetric — the party that knows how little time is left extracts the value of that knowledge.

The intermediary is paid on the fixture, from both sides of it

Commission on conclusion is a reasonable model and it does not reward publishing the price. There is no villain here and there is also no mechanism by which the market becomes more transparent on its own.


02 · What an auction changes

Price discovery, in public, with the volume behind it.

The trick is separating the unit from the contract. The charter party can stay as bespoke as it has always been; what has to be standard is the thing whose price is being discovered.

Route, class and laycan become an instrument

A defined voyage — this route, this vessel class, loading in this week — is a book. The commercial terms that genuinely vary stay in the charter party the parties sign afterwards. The market prices a standard unit; the lawyers keep the bespoke document.

A clock beats a phone for a good that expires

A daily uncrossing at a published time gathers a whole day of scattered interest into one moment and clears it at one price. For capacity that is worthless after a date, a scheduled call is a better mechanism than a race between telephone calls, and it does not reward being the last person told.

A real print for a standard route

The uncrossing price of a defined instrument is a transaction, formed from live orders. Panel assessments become a sanity check on the market rather than the only description of it, and the rest of the chain — including the physical contracts that never touch the venue — has something to quote against.

Orders can rest across the laycan window

GTD validity lets an owner leave an offer working through several days' auctions as the open date approaches, and lets a charterer keep a bid live while cargo readiness firms up. The market runs at the speed the underlying business actually moves.

Fleet operators can offer size without showing it

An iceberg order displays a peak and hides the remainder while contributing its whole volume to the uncrossing. An owner with several ships open in the same region can bring them to market without announcing exactly how exposed they are.

Auction price discovery and the Indicative Equilibrium PriceA chart of cumulative demand and cumulative supply against limit price across eight ticks from 148.10 to 148.45. Cumulative demand falls from 14,400 to 400 as the price rises; cumulative supply rises from 500 to 11,700. Bars behind the curves show the executable volume at each price, which is the lesser of the two. The tallest bar, and therefore the Indicative Equilibrium Price, is 6,300 units at 148.25, leaving a surplus of 900 on the demand side.03,0006,0009,00012,00015,000IEP 148.256,300 executable900 surplus on the demand side148.10148.15148.20148.25148.30148.35148.40148.45Cumulative quantityLimit price · tick 0.05Cumulative demandCumulative supply

03 · What Mehrex supplies

The parts that are configuration rather than a project.

Scheduled auctions on a published clock, credit as a pre-trade limit rather than a phone call, and netting across a day of fixtures.

Lot sizeOne voyage, a fixed tonnage parcel, or one vehicle-day
PriceCurrency per tonne, per day, or as a differential to a published index

04 · What you still have to build

The honest half of the estimate.

Mehrex matches a rate for a standard unit. Everything that makes freight physical — the contract, the vessel, the port, the cargo and what happens when any of them fails — stays outside it.

The charter party, and the law behind it

A matched order is an agreement to fix at a price. The instrument that binds the parties is a charter party or haulage contract with laytime, demurrage, off-hire, bunker and cancellation terms, under a governing law with an arbitration seat. Standard forms exist; getting your market onto one is a commercial project.

Vetting, and who is allowed to carry what

Charterers vet vessels; shippers vet hauliers. Age, class, flag, inspection history, insurance and cargo compatibility all gate whether a nominated carrier is acceptable at all. That gate has to sit in membership and instrument eligibility, and someone has to operate it.

Performance risk, which is not credit risk

The common failure is not non-payment but non-performance: a vessel that does not arrive in the laycan window, a load that is not ready. Pre-trade limits do nothing about that. Substitution rules, cancellation rights and a remedy framework are rulebook work.

Operations after the fixture

Port agency, bunkering, scheduling, documentation, customs and demurrage claims. The trade-capture record tells your operations team what was fixed; running it is the business you are actually in, and it is where the staff cost sits.

Bringing the brokers in rather than going around them

Broker relationships are the liquidity. A venue that positions itself as their replacement launches into an empty book with a hostile industry; one that gives them a member account, an execution channel and a defensible price has a chance. This is the commercial decision the whole project turns on.

Whether a standardised freight contract is a derivative

Physical fixtures are one thing; a standardised, transferable, index-referenced freight contract is treated as a derivative in many jurisdictions, with venue authorisation and reporting attached. Freight derivatives already trade on that basis. Establish which side of the line your product sits on before you design it.


Questions

What evaluators ask first.

How can a bespoke charter party trade as a standard instrument?

It does not — the two are separated. The instrument standardises only what the price refers to: route, vessel or vehicle class, and laycan window. The parties still sign a charter party covering the terms that genuinely vary between them. The market discovers a rate; the contract governs the voyage.

Why a call auction rather than a continuous book?

Because interest in a specific route and laycan is scattered across a day and the good expires. A daily uncrossing concentrates that interest into one moment and clears everyone at one price, which produces a more reliable reference than a continuous book that is empty most of the time. Mehrex runs either, configured per instrument.

Does this replace shipbrokers?

It should not, and a venue designed on that premise will fail. Brokers hold the relationships and the cargo knowledge that make a market liquid. The realistic model is brokers as members, executing on a venue that gives their clients a defensible price rather than an assessment.
