Market Transparency

European Union – October 31, 2026 -- The EU Agency for the Cooperation of Energy Regulators (ACER) has published the first of three sets of revised REMIT data reporting guidance. Its first-phase requirements apply from 29 October 2027.

Three-phase rollout runs from October 2027 to July 2028

The revised REMIT framework (2024) and its secondary legislation (2026) introduce new reporting obligations in three phases between October 2027 and July 2028. ACER is issuing one guidance set per phase. Until 29 October 2027, reporting continues under the current framework and existing guidance.

The first set covers exposure and continuous reporting, LNG market data and bilateral transactions with energy-intensive consumers.

European Union – October 29, 2026 -- The European Securities and Markets Authority (ESMA) has updated its transparency manual with new guidance on identifying over-the-counter (OTC) derivatives subject to transparency requirements and on applying the tick-size regime.

ESMA specifies how OTC derivatives reference data must be supplied

The update clarifies how identifying reference data for OTC derivatives should be provided for transparency purposes. ESMA aims to make the data reported to, and published through, the consolidated tape more consistent.

The guidance on OTC identifying reference data remains a draft until the related technical standards enter into force: RTS 2 and the RTS on CTP input/output data.

ATHENS – October 29, 2026 -- Greece Sotheby's International Realty has published closed-transaction data for the Ionian prime market, covering €200.8 million of completed sales on Corfu, Paxos, Lefkada and Kefalonia since 2018, including six sales above €10 million. The report, titled The Prime and Super-Prime Ionian Property Market, relies on sales the firm brokered itself rather than on asking prices.

Corfu accounts for €138.3 million of the firm's Ionian sales, five of them above €10 million

The Corfu record includes the island's two highest residential sales: a Kassiopi property sold in 2024 for more than €15 million and a Nissaki property sold in 2026 for between €14 million and €15 million. On Paxos, the firm completed the three highest prices ever paid on the island, the first just above €5 million. It also holds the highest-value sale on both Lefkada and Kefalonia. Its Private Office closed the Lefkada deal, at around €11 million, in 2024.

European Union – October 27, 2026 -- The European Securities and Markets Authority (ESMA) has finalised its revised Market Abuse Regulation (MAR) guidelines on delaying the disclosure of inside information, adding five legitimate interests that issuers can cite to justify a delay.

Under MAR, issuers must disclose inside information concerning them as soon as possible, so that investors are informed and insider dealing is prevented. Issuers may delay disclosure in specific circumstances to avoid prejudicing their legitimate interests. The guidelines give issuers a non-exhaustive list of such interests. The update completes the revised regulatory framework.

Five new legitimate interests follow public consultation

After a public consultation, ESMA added five situations in which a delay may be justified:

London – September 28, 2026 -- TotalEnergies has accepted an offer for a 950,000-barrel Nigerian Qua Iboe crude cargo at a premium of $4.10 per barrel to Dated Brent, marking the first west African (WAF) crude transaction executed on the Argus Open Markets (AOM) platform. The deal carries an estimated value of more than $115mn.

First WAF crude deal completes on Argus screen-based platform

The transaction originated on the WAF crude AOM stack, a venue operated by price-reporting agency Argus Media that lets registered participants post bids and offers and initiate trades within a visible, auditable framework. The trade builds on rising participation from producers, traders and refiners who have used the platform to test liquidity and show value ahead of this first completed deal.
