By 8:00 PM local time in Cuba, the informal currency market wrapped up its trading day on Tuesday, September 1, 2026, presenting a relatively stable picture for the U.S. dollar. Meanwhile, the euro experienced a modest decline, and the MLC saw a more pronounced drop, though data was sparse. The three key currencies in Cuba's parallel market ended the day with varied performances, with the U.S. currency remaining steady while the other two adjusted downward.
The American dollar closed the day trading at 678 Cuban pesos (CUP), maintaining its level from the previous day and reflecting no changes from the morning's opening rate. Over the past week, however, the greenback has risen by 10 pesos—approximately 1.5%—from 668 CUP a week ago. On a monthly scale, today's rate is 5 pesos higher than 30 days ago, although this comparison should be approached cautiously as it may be influenced by methodological adjustments in the index as well as market fluctuations. Over the past month, the dollar has ranged from a low of 663 CUP to today's high of 678 CUP, highlighting its pivotal role in the informal market amid ongoing currency shortages.
In contrast, the euro concluded the day at 768 CUP, marking a 1.5-peso drop from the previous session, where it stood at 769 CUP. Despite this slight retreat, the euro has gained 12.5 pesos over the last week—a 1.7% increase—compared to the 755 CUP from seven days ago. On a monthly basis, the euro has decreased by 20 pesos since 30 days ago when it reached 788 CUP, though this change may partly reflect methodological index adjustments. The euro's peak in the past 30 days was 788 CUP, with a low of 746 CUP, maintaining a 90-peso advantage over the dollar, thus reinforcing its leading position in Cuba's parallel market.
The MLC ended the day at 462 CUP, though this figure should be seen as indicative due to limited data availability at this hour. Compared to the previous day, when it was at 479 CUP, it has decreased by 17.5 pesos, a 3.7% drop. Over the past week, it has fallen by 10 pesos from the 472 CUP mark. Over the month, the digital currency has fluctuated between a low of 408 CUP and a high of 529 CUP, displaying significant volatility. Due to its lack of physical presence, its use is limited to state-run stores that accept it, restricting its circulation compared to cash currencies.
Exchange rates at a glance: USD to CUP is 678, EUR to CUP is 768, and MLC to CUP is 462 (indicative value due to limited data). The official exchange rates set by the Central Bank of Cuba (Segment III) are significantly lower, with the dollar at 636 CUP and the euro at 739 CUP, lagging behind the practical rates in the informal currency market.
Although Segment III was introduced as a more flexible exchange mechanism, its official rates remain far from those in the informal market and fail to meet the real demand for foreign currency among the population. Over the past month, the official dollar rate has risen from 615 to 636 CUP, and the euro from 707 to 739 CUP, following an upward trend that still falls short of bridging the gap with the parallel market.
In a scenario marked by persistent inflation, low state salaries, and increasing partial dollarization, any fluctuation in the informal market directly impacts domestic prices and the purchasing power of Cubans. The 42-peso gap between the official and informal dollar rates—and 29 pesos in the euro's case—illustrates the disconnect between the formal economy and the daily reality for most Cubans.

Understanding Cuba's Informal Currency Market
What factors influence the informal currency market in Cuba?
The informal currency market in Cuba is influenced by factors such as currency shortages, inflation, and the partial dollarization of the economy. These elements create a gap between official and informal exchange rates, impacting daily transactions and the purchasing power of Cubans.
Why is there a difference between official and informal exchange rates in Cuba?
The disparity between official and informal exchange rates arises from the formal economy's inability to meet real currency demand, forcing individuals to turn to the informal market where rates reflect practical supply and demand dynamics.
