Spain’s ratings upgrades add to sunny outlook for markets bull run

Spain is demonstrating significant economic and market outperformance within the Eurozone, with its IBEX 35 index leading developed markets in 2025, driven by a robust banking sector and attractive valuations. This resurgence is underpinned by a strong economic growth forecast of 2.7% for 2025, a declining debt-to-GDP ratio, and enhanced political stability, which have collectively prompted triple credit rating upgrades from major agencies. Consequently, Spanish fixed income has become the most popular major European market for inflows, with investors now demanding less compensation for Spanish debt than French, despite recent net outflows from Spanish equities.

Analysis

Spain is demonstrating significant economic and market outperformance relative to its Eurozone peers, driven by a confluence of strong fundamentals and positive investor sentiment. The country's blue-chip IBEX 35 index has surged 30% in 2025, becoming the top-performing developed market and nearing its 2007 peak, largely propelled by an 81% rally in its banking sector index. Despite this run-up, valuations remain attractive, with the IBEX trading at 12.5 times forward earnings, and Morningstar data indicates investor positioning is not crowded, with net outflows of 845 million euros from Spanish equities this year. This contrasts sharply with the fixed income market, where Spanish debt has attracted a leading 23.385 billion euros in net inflows, compressing the 10-year Bono-Bund spread to its narrowest since 2009 and notably inverting the spread against French sovereign debt. This market confidence is underpinned by a robust macroeconomic outlook, including a 2.7% growth forecast for 2025—far exceeding Germany's 0.2%—and disciplined fiscal consolidation, with the deficit projected to fall below 3% of GDP. These factors have earned Spain a triple credit rating upgrade from Moody's, Fitch, and S&P, solidifying its status as a standout performer in the region.

Key Decisions for Investors

• Investors should consider increasing exposure to Spanish equities, particularly financials, given the combination of strong economic momentum, attractive valuations at 12.5 times forward earnings, and evidence of under-positioning from recent net fund outflows.
• The inversion of the Spanish-French sovereign bond spread and strong inflows into Spanish 'Bonos' support relative value trades favoring Spanish assets; however, with the Bono-Bund spread at a post-2009 low, new positions should carefully weigh the potential for further compression.
• Monitor Spain's ability to maintain its superior growth forecast of 2.7% and its deficit reduction trajectory, as these are the core fundamental pillars justifying its asset outperformance against stagnating peers like Germany and France.
