The Santiago Stock Exchange (SSE) - known in Spanish as the Bolsa de Comercio de Santiago - is the largest exchange in Chile and the third largest stock exchange in Latin America. The SSE was founded on 27 November 1893.

Historically, the SSE has been home primarily to large Chilean issuers. Over the last decade, however, the market has seen a growing presence of mid‑cap companies, foreign issuers, exchange‑traded funds (ETFs), structured products, derivatives, and sustainable finance instruments, including green and social bonds.

As of January 2026, the SSE had 185 listed issuers; daily trading volumes in the range of US$2 billion; and a market capitalization of approximately US$302 billion.

The SSE does not specialize in or formally encourage listings by particular types of companies or sectors. Issuers from all industrial sectors and sizes have been listed on the SSE. In recent years, however, the SSE has prioritized the expansion of new financial products, including ETFs, derivatives, venture-type instruments, and ESG-linked securities.

The SSE publishes several benchmark indices used by local and international investors:

• S&P IPSA: The flagship index, tracking the largest and most liquid Chilean stocks; it is widely used as the benchmark for the Chilean equity market.
• S&P/CLX IGPA: A broader market-capitalization-weighted index covering most Chilean listed shares.
• INTER-10: Focusing on major Chilean companies with international exposure.

The SSE is fully integrated in the Latin American Integrated Market (MILA) and is simultaneously undergoing a structural evolution through Nuam, the new regional exchange holding that unifies Chile, Colombia, and Peru.

Through MILA, investors can trade Chilean equities via local brokers, while custody and settlement remain in the market of origin. MILA enables access to 700+ listed companies across member markets and harmonized trading, clearing, and custody arrangements.

While MILA remains legally and operationally in place, the SSE is now part of a deeper integration model called Nuam, which is a regional holding and unified market platform integrating the SSE, the Colombia Stock Exchange (BVC) and the Lima Stock Exchange (BVL).

Nuam goes beyond MILA’s order‑routing model, moving toward a single trading platform, harmonized post‑trade infrastructure and common operational and regulatory standards.

In November 2023, the three exchanges formally announced the creation of the Nuam regional holding. During 2024 and 2025, key regulatory and operational milestones were achieved, including regulatory approvals, technology consolidation (including Nasdaq‑based trading and post‑trade systems), and the approval of unified operational manuals.

As of February 2026, the corporate integration process is substantially complete, with final corporate reorganization steps scheduled for completion in Q1 2026, marking the full consolidation of control under the Nuam structure.
