## Trading Hours: Understanding When the Madrid Stock Exchange Operates

The Madrid Stock Exchange represents the financial heart of Spain, and its operation is essential for anyone wishing to participate in the Spanish markets. Below, we break down the most relevant operational details of this centennial institution.

## Trading Day: When It Starts and Ends

On weekdays (Monday to Friday), regular trading **begins at 9:00 am** local time (CEST). The session **ends at 5:30 pm** in the same time zone.

Before the official start of the trading day, there is a period called the opening auction, which runs from 8:30 am to 9:00 am. This mechanism combines pending orders from the previous session with new buy and sell instructions, determining the initial trading price.

Similarly, after the conclusion of regular trading, a closing auction operates between 5:30 pm and 5:35 pm, where final prices are balanced and orders that did not find a counterparty during regular hours are executed.

## Spanish Market Structure: Much More Than Madrid

Although the Madrid Stock Exchange is often referred to as a single entity, the reality is more complex. Spain operates the SIBE (Sistema de Interconexión Bursátil Español), which coordinates and links four stock exchanges: Madrid, Barcelona, Valencia, and Bilbao. Since 1995, these four exchanges have operated under an integrated structure, and since 2001, Bolsas y Mercados Españoles (BME) has taken over their administration.

The IBEX 35 index, created on January 14, 1992, includes the 35 largest companies by market capitalization in Spain, serving as the main indicator of the country’s economic health.

## Historical Roots and Institutional Evolution

The Madrid Stock Exchange was officially founded on September 10, 1831, when the Sevillian jurist Pedro Sainz de Andino drafted the law establishing it. Commercial operations began on October 20 of the same year, with banks, steel companies, and railway companies as the first traded assets.

The geographic expansion of the Spanish stock market system developed gradually: Bilbao added its exchange in 1890, Barcelona in 1915, and Valencia more recently in 1980. This evolution reflects the modernization and diversification of the Spanish economy over more than a century.

## Market Players: Companies with Global Reach

The Madrid market hosts a select group of Spanish corporations with international relevance. Among them, the financial sector stands out, represented by institutions like BBVA and Banco Santander. The construction and infrastructure segment is reflected in companies such as ACS, Ferrovial, and Acciona. In retail, Inditex demonstrates Spain’s competitive capacity on a global level.

## Non-Trading Days and Shortened Sessions

The Madrid Stock Exchange publishes its trading calendar annually. For 2025, the holidays when no trading occurs are: January 1, April 18, April 21, May 1, December 25, and December 26.

Additionally, there may be days with reduced trading hours, according to the official calendar.
