How does the BCCR set the exchange rate?
Understand the role of Costa Rica's Central Bank, the MONEX market, and how the reference exchange rate is determined.
The role of the Central Bank
The Central Bank of Costa Rica (BCCR) plays a fundamental role in the foreign exchange market. Although Costa Rica has a managed floating system where the market determines the exchange rate, the BCCR has the authority to intervene when it deems necessary to maintain stability.
What is MONEX?
The Foreign Currency Market (MONEX) is the electronic platform administered by the BCCR where authorized financial entities buy and sell currencies among themselves.
Who participates in MONEX?
- Commercial banks (public and private)
- Authorized exchange houses
- Credit unions and cooperatives
- Brokerage firms
- The BCCR itself (when intervening)
How does it work?
- Entities place buy and sell orders on the platform
- When a buy order matches a sell order, the transaction is executed
- The resulting price from these transactions forms the basis of the exchange rate
The reference exchange rate
Each day, the BCCR calculates and publishes the reference exchange rate based on MONEX transactions. This reference rate is expressed with two values:
- Indicator 317: Reference buy rate
- Indicator 318: Reference sell rate
When is it published?
The BCCR publishes the reference exchange rate for the next day around 5:30 PM the day before. This means when you see the reference rate on a Monday morning, that value was calculated on Friday afternoon.
Is it the price at which I can buy or sell?
No. The reference rate is exactly that — a reference. It's a market indicator, but each financial entity sets its own buy and sell price, which will generally be above or below the reference rate.
The BCCR exchange window
The BCCR operates an exchange "window" (ventanilla) where it publishes the rates each authorized entity reports. This information is public and updates throughout the day as entities report changes.
Typical update schedules
- 8:00 - 9:30 AM: Most banks and entities report their daily rates
- 12:00 - 1:00 PM: Some exchange houses update their rates at midday
- Rest of the day: Rates generally remain stable until close
Update frequency by entity type
Not all entities update at the same frequency:
- Public banks: Once daily, early in the morning
- Private banks: Once daily, generally between 8-9 AM
- Exchange houses: May update multiple times per day, especially digital operators
- Cooperatives and mutuals: Once daily
What can the BCCR do when the exchange rate fluctuates significantly?
The BCCR has several tools:
- Direct intervention: Buying or selling dollars in MONEX to push the price in a direction
- Market signals: Official communications indicating the BCCR's position
- Reserve requirements: Changing the reserve requirements banks must maintain in dollars
- Monetary policy rate: Adjusting the colon interest rate, which indirectly affects dollar demand
Why does this structure exist?
The Costa Rican system seeks a balance:
- Market freedom: Entities compete on price, benefiting consumers
- Stability: The BCCR can intervene to prevent sharp movements affecting the economy
- Transparency: All reported rates are public and verifiable
- Regulation: Only entities authorized and supervised by SUGEF can operate in the foreign exchange market
