Small open economies like Costa Rica rarely control the timing or direction of their exchange-rate cycles. Instead, they are often price takers in the global financial system, subject to the flows of international capital, trade and movements in the dollar. The recent surge of Costa Rica’s colón is an example of the dilemmas such economies face when global and local forces collide, testing the credibility of their monetary frameworks.
In February 2026, the colón appreciated to its highest levels in over a decade. This appreciation was the product of two forces. First, Costa Rica has benefitted from a sustained dollar supply, robust tourism, resilient services and goods exports, and foreign direct investment. In a relatively shallow local currency market, these persistent inflows exert significant pressure on the colón.
Second, this domestic story has been reinforced by the external environment. The dollar has weakened broadly over the past year. Even in the absence of changes in Costa Rica’s fundamentals, global dollar weakness lowers the dollar/colón foreign exchange rate. When combined with strong domestic inflows, the result can be an accelerated appreciation of the local currency.
The central bank’s exchange-rate management
The steep appreciation of the colón has reopened the debate over the appropriate balance between exchange-rate smoothing and monetary-policy orthodoxy. Costa Rica operates a managed float under an inflation-targeting framework. In such regimes, the exchange rate is a shock absorber, not a policy target.
However, when appreciation accelerates beyond what domestic prices and wages can adjust to in the short run, the central bank faces a calibration problem: how to smooth volatility without undermining its mandate of stable inflation. According to Banco Central de Costa Rica MONEX data, the weighted average exchange rate fell to ₡472.50 on 23 February and ₡475.18 on 24 February. Retail quotes reported on 21 February placed the buy rate at ₡471.99.
These levels as the strongest for the currency in more than 10 years. The central bank has stepped up its purchases of dollars in the wholesale market, with intervention in early 2026 estimated at over $1bn. Officials have framed these operations as efforts to moderate volatility rather than defend a fixed exchange-rate level.
Importantly, there is limited evidence that the episode is primarily a speculative carry trade. Interest-rate differentials between Costa Rica and the US have narrowed significantly from prior peaks. The appreciation appears more consistent with real-sector flows and balance-sheet preferences than with short-term positioning.
Intervention and liquidity challenge
The central bank’s intervention makes the Banco Central de Costa Rica the marginal absorber of excess foreign-exchange supply. Foreign-exchange purchases inject colón liquidity into the banking system. Unless carefully managed through open-market operations to align system liquidity with the desired monetary stance, this extra liquidity can undermine the central bank’s ability to control inflation and interest rates.
In small open economies that are highly sensitive to global capital flows, the risk is that these interventions will be perceived as an implicit exchange-rate floor. If the market believes the central bank will always step in to prevent further appreciation, it can create one-sided bets and complicate future policy decisions. In small open economies, credibility is often the most valuable buffer against volatility.
Calls for additional policy rate cuts have intensified. The argument is that narrower interest differentials could reduce incentives to hold colón assets and modestly rebalance foreign-exchange demand.
Uneven economic effects
Appreciation is never neutral; it redistributes income across economic sectors. For exporters and tourism operators, who earn predominantly in dollars while pay local costs in colóns, a stronger currency compresses margins and can delay investment and hiring decisions, reducing the competitiveness of Costa Rican goods and services in the global market.
On the flip side, a stronger colón benefits consumers with cheaper imported goods and energy prices, dampening tradables inflation and supporting real incomes. It also boosts public finances, as it reduces the colón value of foreign-currency public debt, improving headline fiscal metrics. These gains are meaningful in an economy that has undertaken significant fiscal consolidation in recent years.
The net effect depends on persistence. Temporary overshooting can impose unnecessary adjustment costs. A durable improvement in the external position, by contrast, implies that some real appreciation is equilibrium-consistent.
Structural shift or cyclical amplification
The central question facing policy-makers is whether Costa Rica’s currency surge reflects structural strength in the country’s external position or a transitory response to global dollar weakness. If sustained inflows from high-value services, tourism and investment represent a lasting change in Costa Rica’s external accounts, then resisting appreciation indefinitely would be costly and counterproductive.
However, if the move is primarily driven by a cyclical downturn in the dollar, partial reversal is plausible once global conditions stabilise. In that scenario, excessive intervention could leave the central bank exposed to balance-sheet and credibility risks.
For small, dollar-dependent economies, these episodes are a recurring test of central banking skill. The task is not to prevent adjustment, but to manage its pace and ensure that short-term volatility does not compromise macroeconomic stability or policy credibility. Costa Rica’s experience offers a view of the broader challenges faced by small open economies across the world as they navigate the turbulence of local fundamentals and global dollar cycles in an era of persistent uncertainty.
