FuelEU surplus prices & index: what market participants should look out for

The FuelEU surplus market faces a mushrooming of prices, while it suffers from a lack of clarity about what those prices actually represent. Every week, market participants hear different numbers. All of them may be useful in some way, but they are not the same thing.

FuelEU surplus prices became a real settlement item. Owners and charterers need reference prices for charter party clauses. Shipping companies need them to compare pooling, biofuels and penalties. Buyers need them to understand whether they are overpaying. Sellers need them to understand whether they are underselling. This is why distinction between the prices is important. A number that looks like a market price but is not supported by the right methodology can create real commercial distortion.

What an index is supposed to do

An index is a number produced under a methodology rather than just a publication. The underlying methodology determines what the index measures, what data it accepts, how that data is treated, and whether the output is suitable for the decision it is being used for. This is the core lesson from mature benchmark markets and from IOSCO-style benchmark thinking: the credibility of an index depends on governance, data quality, methodology and transparency.

This is particularly important in new markets. In mature markets, participants usually understand the difference between a transaction price, an offer, a bid and an assessed value. In emerging markets, these categories are often blurred. That is exactly what is happening in FuelEU.

Too often, the market speaks about “the FuelEU price”, while the relevant question is not only what the number is. The relevant question is where it comes from. Just asking for the price is simply too imprecise.

Lessons from established maritime indices

Shipping already relies heavily on indices and price assessments, but not all of them are built in the same way.

In container freight, for example, transaction-based approaches such as NYSHEX are designed to reflect where freight has actually moved under agreed commercial terms. This makes the methodology particularly relevant where the index is intended to support settlement or risk management. Other container freight indices may be based on reported rates, platform data or market submissions.

Marine fuel markets provide another useful comparison. Price reporting agencies such as Argus and S&P Global Commodity Insights have long published bunker assessments used across the industry. These assessments are often based on a combination of reported transactions, bids, offers, market conversations and editorial judgement. In liquid markets, actual trades provide the strongest anchor. In less liquid markets, assessors may need to determine where the product could have traded based on available evidence.

The important point is that serious users of indices understand the methodology before relying on the number. A bunker assessment, a container freight index and an executed-trade benchmark may all be valuable, but they are built from different data.

FuelEU surplus should be treated with the same discipline. A number based on executed trades, a number based on offers, and a number based on an assessed market view should not be treated as interchangeable.

A posted price is not an index

In this context, it is worth underlining that a posted price may be useful, but it should not be confused with an index.

A pool organiser may publish the price at which it is willing to sell. A trader may share an indicative level. A seller may quote a surplus price to the market. These numbers can help with price discovery, but they usually reflect one participant’s commercial position. That participant may have surplus to sell. It may have a pool to fill. It may have a specific risk appetite, customer base or commercial strategy. The number may be entirely legitimate, but it is not automatically a neutral benchmark.

The same applies to listed offers. An offer shows where someone is willing to sell. It does not show where a deal was closed. If a market participant presents offer data as if it were transaction data, users should be careful. It affects settlement, procurement and compliance planning.

FuelEU is especially sensitive to this because surplus is not a simple commodity and ask prices are linked to pooling execution and counterparty risk.

Which index is fit for which purpose?

Different types of price information are useful for different purposes:

A bid index helps sellers understand where demand may sit. An ask index helps buyers understand where supply is being offered. A bid-ask spread can show whether the market is becoming more liquid or remains fragmented. These are useful tools for price discovery. They are not, however, the best basis for settlement.

For charter party settlements, internal transfer pricing and fair-value discussions, executed trades are the most relevant input. The reason is simple: settlement should be based on where comparable value actually changed hands, not where one side of the market wanted it to change hands.

Assessed prices can also have a role, especially where transaction data is limited. This is common in physical commodity markets. Price reporting agencies often use reported trades, bids, offers and market conversations to assess where a product could have traded. That model can work, but only if the methodology is transparent and judgement is governed.

For FuelEU, this distinction is crucial. A bid or ask number may be useful for understanding the market. A posted price may be useful for understanding one seller’s position. An assessed price may be useful if the market is illiquid. But for settlement, the strongest foundation is executed trades.

Executed trades are different

The strongest basis for a FuelEU surplus index is executed transactions. An executed trade shows where a buyer and seller actually agreed. It reflects a real transfer of economic risk. It is not a seller’s ambition, not a buyer’s wish, and not a market participant’s view of where the price should be. It is where the market cleared.

This is why executed-trade-based indices are more suitable for settlement than offer-based or indication-based numbers. If an owner and charterer are settling real economic value, they should ideally rely on a reference that reflects real transactions. Otherwise, one party may be paying or receiving an amount based on market intention rather than market reality.

This does not mean that transaction-based indices require no methodology. Trades may differ by timing, volume, counterparty, delivery certainty and contract structure. A robust index must still decide which trades are included and how they are treated. But these are questions of refinement. The starting point remains stronger: executed trades are evidence of where the market actually cleared.

Why FuelEU needs a serious surplus index

FuelEU surplus pricing directly affects money flows between real market participants. It determines whether a buyer overpays, whether a seller undersells, whether a charterer compensates an owner correctly, and whether a compliance strategy is commercially rational.

In an opaque market, intermediaries benefit from information asymmetry. They see more of the market than the underlying buyers and sellers. That may be normal in the early phase of a market, but it should not become the permanent structure.

A credible surplus index reduces that asymmetry. It gives shipping companies and charterers a reference point that is not dependent on selective indications, private conversations or one party’s posted price. It also improves the quality of contractual settlement. If the reference price is clear, disputes become less likely. If the reference price is unclear, the settlement mechanism itself becomes a source of risk. This is why methodology matters.

Conclusion

FuelEU has created a new compliance market. That market needs proper price transparency. But transparency does not mean publishing more numbers. It means publishing numbers that users can understand and rely on.

The next time a FuelEU surplus price or index is quoted, the first question should be: where does this number come from?

If it is based on executed trades, it reflects where the market actually cleared. If it is based on bids or asks, it reflects market intention. If it is a posted price, it reflects one participant’s commercial position. If it is assessed, users should understand the judgement behind it.

These distinctions matter. Using the wrong number can mean overpaying, underselling, or settling a charter party on the wrong basis. FuelEU surplus is too valuable, and too important, to be priced on ambiguity.
