Economy and politics agenda: CHP court ruling rattles markets

An appeals court in Ankara annulled the Republican People’s Party (CHP) 2023 congress on May 21-22, 2026, effectively removing party leader Özgür Özel and reigniting a political standoff that quickly reverberated through financial markets.

Following the court decision, trading at Borsa İstanbul was briefly suspended and equities suffered steep losses, with reports indicating roughly a 6% drop in the main index in early reactions. Government bond prices fell and credit spreads widened as investor uncertainty rose; political actors presented contrasting narratives about the legality and motive of the ruling.

Market indicators showed immediate stress: the Turkish lira weakened against the dollar, foreign portfolio concerns increased, and sell-offs in local assets were registered. Several financial institutions signaled that the shock raised the likelihood of tighter monetary policy in the near term, with some notes pointing to a potential one-week repo rate increase at upcoming Central Bank meetings.

The episode underscores how political developments in Turkey can affect economic stability and investor confidence. Commentators drew parallels with earlier political shocks, including the March 2025 arrest of Istanbul Mayor Ekrem İmamoğlu, and warned that repeated political interventions risk elevating risk premia and deterring inflows.

Analysts recommend close monitoring of policy responses from the Treasury and the Central Bank, while noting that short-term volatility is likely to continue until clarity returns on the opposition’s leadership and legal appeals progress. Market participants expect heightened sensitivity to domestic political news and external risk factors in the coming weeks.
