Corporación Bananera Nacional S.A. (CORBANA)

What it is

CORBANA is a public non-state entity of Costa Rica — a legally peculiar creature that is neither a pure government ministry nor a private company, created to promote the development and sustainability of the country’s banana sector. Its work spans scientific research, technical assistance to growers, and the promotion of Costa Rican bananas at home and abroad.

CORBANA also runs a credit fund that finances working capital and investment for banana producers. It advises the government on banana policy, providing information on the state of the sector and proposing measures to ensure long-term sustainability.

The industry CORBANA represents exports an average of 125 to 126 million boxes of bananas per year, placing Costa Rica among the third- or fourth-largest exporters in the world, with roughly 14% of the global market. The planted area stands at 42,000 hectares — a surface that has been stable for more than 15 years, concentrated on the country’s highest-yielding soils.

Who owns it

CORBANA’s supreme governing body is a five-member board that represents three shareholder groups: the government (whose representative, the board chair, is appointed directly by the President of the Republic), Costa Rica’s state banks (two directors), and banana producers themselves (two directors elected among their peers). No single shareholder group commands a majority alone; decisions require alignment across the three blocs.

CORBANA is not equity-listed and has no market capitalisation or free float. Holders of the company’s Series C shares — banana producers — elect their two board representatives at special shareholder assemblies.

The exact percentage split of share classes A through E across the three groups is not disclosed in publicly available sources.

Who runs it

The General Manager is Marcial Chaverri, who speaks publicly for CORBANA on trade and policy matters. The management team also includes Deputy General Manager Marjorie Ureña and Deputy General Manager for Legal and Corporate Affairs Mariano Jiménez.

The board chair — appointed by the President of Costa Rica — is not named in currently available public filings. The names of the state-bank and producer-elected directors are not disclosed in available sources.

The money, in plain words

CORBANA’s own income statement and balance sheet are not publicly filed; its financial statements are not available through SUGEVAL or the BNV in open-access form. What is clear is the scale of the industry it governs: Costa Rica’s banana exports totalled USD 1.241 billion in 2024, making the sector a pillar of the country’s agricultural export base.

The industry ships more than 125 million boxes a year, representing 7.0% of all Costa Rican exports.

The banana industry directly employs more than 40,000 people, with wages among the highest for banana workers in Latin America, and indirectly supports more than 100,000 more jobs. CORBANA’s own operating budget is funded principally by a per-box levy on banana exports — a quasi-tax that makes the industry its only real client and its only meaningful source of income.

What it is doing now

Since late 2024, the industry has been hit by an unusual surge in rainfall across the main growing zones, which triggered an aggressive outbreak of Black Sigatoka, the most damaging leaf disease affecting bananas. Simultaneously, the Costa Rican colón strengthened sharply — the dollar fell below 500 colones for the first time in years — squeezing growers whose revenues arrive in dollars but whose daily operating costs are paid in local currency.

In May 2025, CORBANA publicly challenged a study by the Universidad Nacional that projected an 18% fall in banana exports to the United States due to the US reciprocal tariff, arguing the projection overstated the risk. The tariff cost, which came into force in April 2025, is being absorbed by the importer, not the Costa Rican grower.

What to watch

• Colón exchange rate. A strong colón reduces the net income of producers, since revenues are in dollars and costs are in colones. Further colón appreciation would tighten margins across the entire sector CORBANA serves.
• Black Sigatoka and climate. The disease weakens plants and forces growers to discard thousands of boxes; Costa Rica has chosen to export less rather than compromise quality. Persistent wet conditions in the Caribbean lowlands could extend the hit into 2026.
• European supermarket pricing. European chains pushed for a price cut of roughly €1.30 per box in late 2023; CORBANA has been pressing for shared responsibility in the supply chain. Any renewal of that pressure would reduce grower income directly.
• Fusarium Tropical Race 4. This fungus — the greatest existential threat to global banana production — has not yet reached Costa Rica’s farms. CORBANA’s research centre is part of the international effort to find resistant varieties before it does.
