In 2021 Belize converted $553M of debt into a $364M "blue loan," cutting debt ~12% of GDP and earmarking ~$180M over 20 years for marine conservation. By 2024 the fund had disbursed BZ$7.3M across 14 MPAs, even as surveys found most assessed fish stocks still declining.

Context

In November 2021, the Government of Belize and The Nature Conservancy, backed by the U.S. International Development Finance Corporation, completed a sovereign debt conversion, creating the Belize Fund for a Sustainable Future.

Objectives

Belize committed to eight ocean-protection milestones, including a Marine Spatial Plan and expanding Biodiversity Protection Zones toward 30% of its ocean territory by 2026 (from an 11.7% baseline in 2021).

Activities

Belize repurchased roughly $553 million of public debt at a 45% discount, refinancing it as a $364 million 'blue loan', cutting national debt by about 12% of GDP and freeing an estimated $180 million over 20 years for ocean conservation.

Results

By late 2024, the Belize Fund reported BZ$18 million approved and BZ$7.3 million disbursed across 14 marine protected areas covering more than 527,000 hectares, reaching 40 coastal communities and training 66 people in long-term marine management.

Conclusions

The record is genuinely mixed: a 2025 independent review found that of 18 assessed species, most remained unsustainably fished, with a regional 60% decline in groupers and snappers and an 85% drop in Nassau grouper abundance at one long-monitored spawning site despite two decades of protection. The Managed Access programme still lacks a formal per-zone licence cap, so institutional capacity is strengthening even as some target stocks keep eroding.

Implementation
Indicative cost
Very high (> €5M) — USD 553m debt repurchased at a 45% discount into a USD 364m blue loan; ~USD 180m projected conservation financing over 20 years; BZD 18m approved / BZD 7.3m disbursed by late 2024.
Time to results
Long (> 3 years) — Deal closed November 2021; milestone target of 30% Biodiversity Protection Zones by 2026; Belize Fund reporting covers its first ~2.5 years (through late 2024).
Staffing & skills
Belize Fund for a Sustainable Future (6 government agencies, 11 NGOs, 1 academic institution, 1 community organisation)

Conditions for success

  • U.S. DFC-backed, TNC-brokered debt conversion lowering borrowing cost
  • Binding milestone commitments (Marine Spatial Plan, Biodiversity Protection Zone expansion)
  • Independent third-party fisheries monitoring (Oceana, 2025 review) creating public accountability

Common failure modes

  • Oceana's 2021 audit found fisheries landings/licensing data still not systematically collected
  • A 2025 independent review found most of 18 assessed fish species remained unsustainably fished despite the funded MPA network
  • The Managed Access programme still lacks a formal per-zone licence cap
