The euro's value in Cuba's informal market has skyrocketed, showing no signs of slowing down as the week begins. Meanwhile, the US dollar remains steady at 435 CUP as of September 29, maintaining a 64-peso difference from the euro. The Euro's Dominance in 2025's Informal MarketThroughout 2025, the euro has seen the most significant increase in value within Cuba's informal market, becoming a key currency for many Cubans aiming to safeguard their savings against the relentless devaluation of the Cuban Peso. Additionally, widespread distrust in the CUP and speculative market behavior, where many buy anticipating further increases, fuel these price hikes. For now, it seems the euro will continue to lead the charge in Cuba's informal market, reflecting the scale of the currency crisis and the irreversible decline of the peso as legal tender.
