Market overview

Spanish securities trade on BME Exchange, the market operator formerly known as Bolsas y Mercados Espanoles and now part of the SIX group. Conduct and market supervision belong to the Comision Nacional del Mercado de Valores, the CNMV, whose powers sit in Ley 6/2023, de 17 de marzo, de los Mercados de Valores y de los Servicios de Inversion. Public debt is issued and managed by the Tesoro Publico, part of the finance ministry, which also handles financial regulation and Spain’s dealings with international financial institutions. Post-trade runs through Iberclear, the central securities depository, whose ARCO system settles securities and cash on the Eurosystem T2S platform, either free of payment or against payment into dedicated cash accounts.

Cash equities trade through SIBE, the electronic interconnection system. The main session runs an opening auction from 8:30 to 9:00, continuous trading from 9:00 to 17:30, a closing auction from 17:30 to 17:35 and Trading at Last from 17:35 to 17:45. Less liquid shares trade in the Fixing segment, which calls an auction at 12:00 and a second at 16:00. Derivatives sit on MEFF; since 2025 IBEX 35 futures have been quotable from 8.00 a.m. to 10.00 p.m. to widen retail access.

The equity ladder is explicit. The main market takes mature issuers, BME Growth serves SMEs, BME Scaleup takes companies at an early stage, and the Pre-Market Environment trains candidates before any listing. BME Easy Access, introduced in 2025, lets a company list without meeting the minimum share distribution on day one and reach it within a set period afterwards. The reference index is the IBEX 35, with the IBEX Medium Cap and IBEX Small Cap below it. In 2025 the IBEX 35 passed 17,000 points in December and closed the year up 49.3 per cent at a peak of 17,308.

Activity figures for that year give the scale. Turnover on BME Exchange rose 24.3 per cent to EUR 525.3 billion, with equities up 21.2 per cent at EUR 384.6 billion and fixed income up 34.1 per cent at EUR 139.3 billion, across 32,001,532 transactions, 6.7 per cent more than in 2024. Three companies joined the main market: HBX Group, Izertis and Cirsa Enterprises. Fourteen more joined BME Growth and BME Scaleup. Listed companies raised EUR 10.9 billion through capital increases, 79.7 per cent more than a year earlier. Securitised derivative listings rose 19.6 per cent to 7,632, stock options turnover reached EUR 1.8 billion and IBEX 35 futures turnover reached EUR 49.0 billion.

Debt is the larger half by issuance. Corporate debt issues grew 52 per cent to exceed EUR 79 billion in 2025, and MARF, the alternative fixed income market for smaller issuers, passed EUR 10 billion of outstanding balance for the first time; AIAF carries government, regional and private paper. Sovereign supply comes from the Tesoro through regular auctions of Letras, Bonos and Obligaciones; its most recent results show 2.387 per cent on 3 month Letras, 3.005 per cent on 5 year Bonos and 3.542 per cent on 10 year Obligaciones. GSN covers the Spanish banks, utilities, infrastructure and telecoms names that dominate the IBEX 35, the SOCIMI property vehicles and technology issuers on BME Growth and BME Scaleup, and Spanish sovereign and regional debt sales.
