The informal currency market in Cuba closed on Monday, August 17, with a slight decline in the US dollar, stability in the euro, and an increase in the MLC, amid persistent demand for foreign currencies and the loss of purchasing power of the Cuban peso.
At 8:00 p.m., the dollar (USD) was trading at 663 Cuban pesos (CUP), while the euro (EUR) remained at 760 CUP. The MLC reached an indicative average value of 462 CUP, although this last reference should be interpreted with caution due to the low volume of transactions.
The , which monitors buying and selling announcements in Telegram and Facebook groups, thus reflects a day of few movements for the main currencies in cash.
The dollar drops to 663 pesos
The dollar closed this Monday at 663 CUP and shows a slight downward trend in the weekly comparison.
Seven days ago, it was at 670 CUP, so it has accumulated a drop of 7 pesos, close to 1%.
Over the past 30 days, the US dollar has fluctuated between 663 and 675 CUP, a relatively narrow range compared to other periods of greater volatility.
Despite the recent setback, the dollar continues to be one of the main benchmarks in the informal market and price formation in the Cuban economy.
The euro holds steady at 760 CUP
The euro closed at 760 CUP, with no changes throughout the day.
In the weekly comparison, however, it shows a decrease: seven days ago it was at 773 CUP, indicating a loss of 13 pesos, approximately 1.7%.
Over the last 30 days, it has traded between 755 and 790 CUP.
The European currency thus holds a significant advantage over the dollar in the Cuban informal market, where its availability is often lower.
The MLC is rising, but its exchange rate remains indicative
The most significant movement corresponds to the MLC, which closed with an indicative average value of 462 CUP.
In contrast to the 423 CUP from a week ago, it has accumulated an increase of 39 pesos, exceeding 9%. Compared to the 430 CUP from 30 days ago, the rise reaches 32 pesos.
These variations should be approached with caution due to the lower volume of transactions in MLC, a digital currency linked to bank accounts, which is primarily used in state establishments that still accept that payment method.
- Exchange rate of the USD to CUP: 663 CUP.
- Exchange rate of the euro EUR to CUP: 760 CUP.
- Exchange rate from MLC to CUP: 462 CUP (indicative value).
Informal quotes continue to exceed the references set by the Central Bank of Cuba (BCC) for Segment III.
With official values of 628 CUP per dollar and 727 CUP per euro, the gap compared to the informal market is around 35 pesos for the dollar and 33 pesos for the euro.
The difference highlights that the new official exchange scheme still coexists with an informal market where currencies reach higher values, in a scenario characterized by the scarcity of foreign currency and the partial dollarization of the economy.
For Cubans, these fluctuations have consequences that go far beyond currency exchange. The dollar and the euro serve as benchmarks for numerous products and services, especially those related to imports, so their changes ultimately affect the cost of living.
The CiberCuba Exchange Rate is an index of the informal market developed through the automated analysis of thousands of currency buy-and-sell posts in Telegram and Facebook groups. The calculation discards atypical offers and spam messages, weighs transactions based on their age, and consolidates a representative value that is updated multiple times a day.
