## Commonwealth Report Finds Risk
The Commonwealth Secretariat estimates US$43.5 billion of Guyana's assets face episodic flooding due to oil-driven coastal development.
## Oil Economy Raises Coastal Exposure
Guyana's oil-driven growth concentrates assets and economic activity on the coast, increasing flood risk exposure.
## Coastal Plain at Risk
About 90% of Guyanese live on a coastal plain 0.5 to 1 metre below sea level at high tide.
## Rising Sea Levels
Georgetown's sea level rises 4.7 to 10.2 millimetres annually, faster than the global average of 3.2 to 3.5.
## Mangrove Losses
Guyana lost 70% of mangrove cover between 1992 and 2015, reducing natural sea defences.
## State Oil Fund
Guyana's state oil savings fund held US$3.6 billion by September 2025.
## Coastal Governance Gap
Guyana lacks comprehensive coastal-zone management law and enforceable building codes.
## Flood Risk Implications
Oil revenue could fund coastal defences but national budget priorities determine allocation.
## Key takeaway

Commonwealth Secretariat estimates US$43.5 billion of Guyana's assets face episodic flooding due to oil-driven coastal development.
