Vox Emerges as Kingmaker After Sánchez Defeat in Andalusia Vote

Prime Minister Pedro Sánchez’s Socialist Party (PSOE) lost the Andalusia regional election on 17 May 2026, securing just 31 of the 109 seats in parliament. The conservative People’s Party (PP) won a decisive plurality with 48 seats, while the right-wing Vox party secured 28 seats. Based on reporting by FT.com, the result grants Vox a potential kingmaker role to form a ruling coalition with the PP in Spain’s most populous region, marking a significant setback for the national government ahead of Spain's next general election.

Context — [why this matters now]

The 2026 Andalusia vote is the first major regional test for Prime Minister Sánchez’s minority coalition government following its formation in late 2025. The last time Vox held decisive coalition power in a major region was in Castilla y León following the February 2022 election, where it entered government alongside the PP. That precedent saw immediate policy shifts on social spending and regional identity.

The current national political backdrop features Sánchez’s government relying on a fragile coalition with leftist and regionalist parties to pass legislation. Spanish 10-year bond yields traded at 3.2% in the week preceding the vote, reflecting moderate but persistent political risk premiums relative to German Bunds.

The direct catalyst for the Socialist defeat was a sharp drop in voter turnout in traditional urban strongholds like Seville and Málaga. This voter apathy, combined with a consolidation of the right-wing vote behind the PP and Vox, transformed a predicted close contest into a rout for the governing left.

Data — [what the numbers show]

The Andalusia parliament comprises 109 seats. The PP's win of 48 seats represents a gain of 4 seats from the 2022 regional election. Vox increased its seat count by 6, from 22 to 28. The PSOE suffered the most significant loss, dropping from 41 to 31 seats. Voter turnout fell to 58.5%, down 6.2 percentage points from the 64.7% recorded in 2022.

Party	Seats (2026)	Seats (2022)	Change
People’s Party (PP)	48	44	+4
Vox	28	22	+6
Socialist Party (PSOE)	31	41	-10
Others	2	2	0

The result gives a prospective PP-Vox coalition a total of 76 seats, a 17-seat majority over the required 55-seat threshold. The Spanish IBEX 35 equity index closed the following session at 11,050 points, a decline of 0.8% versus a flat Euro Stoxx 50 index.

Analysis — [what it means for markets / sectors / tickers]

A PP-Vox coalition government in Andalusia would likely reallocate regional spending, a budget exceeding 40 billion euros. Sectors like renewable energy project development, which thrived under PSOE-led green transition policies, face headwinds. Construction and infrastructure firms with strong regional ties, such as Ferrovial (FER), could benefit from a shift toward traditional public works.

Domestic-focused Spanish banks like Banco Sabadell (SAB) and CaixaBank (CABK) may see reduced political uncertainty if this result signals a more stable right-of-center government after the next national election. A key risk to this analysis is that Andalusia's political dynamics do not directly translate to national outcomes, as Sánchez’s government retains support in other regions like Catalonia.

Market positioning data shows a slight increase in short positions against the iShares MSCI Spain ETF (EWP) in the days following the election. Flow analysis indicates capital is rotating toward large-cap, internationally diversified IBEX constituents like Inditex (ITX) and Iberdrola (IBE), which are less exposed to domestic Spanish fiscal policy.

Outlook — [what to watch next]

The immediate catalyst is the formal coalition negotiation between the PP and Vox in Andalusia, expected to conclude by late June 2026. The policy platform of that coalition will signal the national PP's willingness to accommodate Vox's agenda.

Investors should monitor the next national opinion polls, due for release in early June, for shifts in voter intention. A sustained 10-basis-point widening of the Spain-Germany 10-year bond spread above its current 90 bps would indicate rising sovereign risk perceptions.

Key support for the IBEX 35 is at the 10,800 level, its March 2026 low. Resistance sits at the 200-day moving average near 11,300. A break below support would likely coincide with failed coalition talks and increased prospects for a snap national election.

Frequently Asked Questions

What does the Andalusia election mean for the stability of Spain's government?

The result weakens Prime Minister Sánchez's position but does not immediately threaten his national government. His coalition retains a majority in the national parliament. However, the loss in a key region reduces his political capital and could embolden opposition parties to challenge legislation more aggressively, increasing legislative gridlock risk.

How does Vox's influence compare to other European populist parties?

Vox's potential entry into a regional government aligns with a broader trend of populist-right parties gaining executive power in Europe, such as in Italy and Finland. Unlike some peers, Vox has moderated certain economic policies to facilitate coalition deals, focusing more on cultural issues, which may limit immediate radical fiscal shifts.

Which Spanish stocks are most sensitive to domestic political changes?

Stocks with high domestic revenue exposure are most sensitive. This includes banks like Banco Sabadell, utility Endesa (ELE) due to regulated tariffs, and construction company ACS (ACS). These firms' valuations are closely tied to Spanish GDP growth forecasts, public investment budgets, and consumer confidence, all of which are influenced by political stability.

Bottom Line

The Andalusia election has materially increased the probability of a right-wing coalition forming after Spain's next general election.
