MSCI announced on June 23, 2026, that it would reclassify Bulgaria from Standalone Market status to Frontier Market status. This upgrade reflects improvements in market accessibility and liquidity within Bulgaria. The decision to elevate Bulgaria was part of MSCI's 2026 Annual Market Classification Review, with the reclassification effective from the May 2026 Index Review. Bulgaria had been under review for this potential reclassification since at least April 2025, when MSCI launched a consultation with market participants. Historically, Bulgaria was reclassified from Frontier Markets to Standalone Markets in August 2016 due to declining size and liquidity in its equity market, making this a return to its former classification.
Vietnam's status remained unchanged in the 2026 review, despite its efforts to advance capital market reforms. MSCI noted that challenges such as low free-float levels in some companies and persistent limits on foreign ownership continue to hinder a potential upgrade. Key developments in Vietnam included the introduction of a global broker trading model, the establishment of a Central Counterparty (CCP) company, and progress on English-language disclosure requirements. However, these reforms have not yet been sufficient to address all of MSCI's concerns regarding market accessibility and investment instrument availability.
Argentina also saw no change to its classification. The MSCI Global Market Accessibility Review evaluates five core criteria: openness to foreign ownership, ease of capital inflows/outflows, efficiency of the operational framework, availability of investment instruments, and stability of the institutional framework. These criteria are crucial for institutional investors when assessing a market's investment accessibility. The full report covering 79 markets details MSCI's assessment of these criteria, which guide the classification of markets into Developed, Emerging, Frontier, and Standalone categories.
