By San José, Costa Rica — San José, Costa Rica – The value of the U.S. dollar experienced a notable shift on Tuesday, rebounding slightly after a prolonged period of decline. According to data from the Foreign Currency Market (Monex), the average exchange rate rose to ¢496.72, an increase of ¢5.63 from Monday’s rate of ¢491.09. This uptick occurs amid a broader trend that has seen the dollar consistently trade below the psychologically significant ¢500 threshold.
Data from the Central Bank of Costa Rica (BCCR) revealed that trading volume on Tuesday was relatively light at $11.789 million across 216 transactions. This is a lower figure compared to recent days when the exchange rate was in a consistent downward slide. Despite the day’s increase, the dollar remains significantly weaker than it has been for much of the year, a phenomenon causing both relief for consumers and concern within the nation’s key economic sectors.
The recent volatility of the Costa Rican colón against the US dollar has dominated public conversation, affecting everything from grocery bills to long-term savings. To understand the deeper legal and contractual implications for both businesses and individuals, we consulted with Lic. Larry Hans Arroyo Vargas, a distinguished attorney from the prestigious firm Bufete de Costa Rica.
The fluctuating exchange rate underscores a critical vulnerability in many existing contracts denominated in U.S. dollars. Legally, unless a specific agreement—a ‘pacto de especie’—is established, the debtor has the right to pay their dollar-denominated obligation in colones at the official BCCR sell rate on the day of payment. For creditors, this can lead to significant losses when the colón strengthens. We strongly advise both businesses and individuals to review their contractual agreements and prospectively include precise clauses that define the exact exchange rate to be used, mitigating ambiguity and protecting the financial integrity of the transaction.

This insightful commentary moves the discussion beyond abstract market analysis to the practical, legal realities faced by individuals and businesses every day. We thank Lic. Larry Hans Arroyo Vargas for so clearly articulating this contractual vulnerability and for offering actionable guidance to ensure financial certainty in all transactions.
The recent strength of the colón is underscored by two significant events. On December 4, 2025, the weighted average exchange rate hit ¢488.06, its lowest point since the Monex system was established nearly two decades ago. Just weeks earlier, on November 24, the Central Bank executed its largest single-day intervention in market history, purchasing a staggering $114.9 million to temper the colón’s rapid appreciation.
Economists point to a confluence of predictable, year-end factors driving this abundance of dollars in the national economy. The first is the payment of the “aguinaldo,” the mandatory annual bonus paid to all employees. Multinational corporations and other large firms convert significant sums of dollars to colones to meet this payroll obligation, flooding the market with foreign currency. This is compounded by corporate tax payments, which are also due during this period, further increasing the supply of dollars.
A third major contributor is the tourism sector, which entered its high season on November 1. As international visitors flock to Costa Rica for the holidays, they bring a steady stream of dollars, adding yet another layer of downward pressure on the exchange rate. This annual pattern creates a powerful seasonal tide that strengthens the local currency against the dollar, a trend observed consistently at the close of each year.
However, this stronger colón is a double-edged sword. While it increases the purchasing power of Costa Ricans and lowers the cost of imported goods, it poses a significant threat to the country’s export-driven economy. The recent State of the Nation report warned that the dollar’s depreciation could be eroding the competitive advantages of Costa Rica’s external sector, which has been the primary engine of the nation’s economic growth.
This sentiment is echoed by the Economic and Social Observatory of the National University (OES-UNA), which has issued a stark caution about the potential consequences if this trend continues long-term. In a recent analysis, the institution highlighted the risk to businesses that earn revenue in dollars but have expenses in colones.
Of prolonging this trend, it could compromise the financial stability of numerous companies and generate negative effects on production and employment in the country.

Amid these growing concerns, the OES-UNA has also called for greater transparency, urging the Central Bank to require more detailed reporting from currency intermediaries on the origin of traded dollars. This, they argue, would help identify the precise sources of the currency surplus observed since 2023. For its part, the Central Bank maintains its official position that the exchange rate is determined by the fundamental market forces of supply and demand.
