Single Order Book

The Euronext regulated markets operate a unique Single Order Book model.

How it works

The Single Order Book enhances liquidity, lowers costs, and facilitates access to capital markets by delivering harmonised cross-border trading, clearing and settlement.

• All Euronext-listed securities are designated a single trading line in the Single Order Book, and most have a single trading code. -

• In the case of securities with a multiple listing within the Euronext markets, trading will take place on a single trading line, the designated Market of Reference (MoR).

• Liquidity is consolidated in each security to enhance spreads and market depth, and achieve better price formation.

• Issuers may choose to list on more than one market to enhance visibility, qualify for inclusion in local indices, or have trading volumes and prices published in the national press. The Single Order Book will execute their trades on one trading line: the designated Market of Reference.

Case Study: ING

ING (headquartered in the Netherlands) is listed on two markets, but because its Market of Reference is Euronext Amsterdam, all orders from the other marketplace (Brussels) are brought into the Amsterdam market order book.

Even though ING orders are not executed on Euronext Brussels, it is still considered a listed company in Belgium, and must therefore comply with regulations in both market locations, Belgium and The Netherlands.

As a benefit, ING can also promote its shares as a group, having made a public offer in both countries.
