Catastrophe Bonds (CAT Bonds)

Catastrophe (CAT) bonds are high-yield debt instruments that provide rapid liquidity after natural disasters, such as hurricanes and earthquakes, by transferring risk to investors. The document details how these bonds are structured using parametric or industry-loss triggers and identifies the roles of commercial providers, multilateral development banks (MDBs), and regional pools. It outlines the internal and regulatory capacities governments need to issue these bonds, the challenges of basis risk and high transaction costs, and provides examples of sovereign issuances in countries like Mexico, Chile, and Jamaica.

• CAT bonds function by transferring financial risks from insurers or governments to investors; investors receive interest but may lose their principal if a specific disaster trigger is met.
• The instruments are applied across various sectors to manage systemic risks: agriculture and fisheries use them for crop failure hedging, governments use them for infrastructure reconstruction to avoid emergency debt, and utilities use them for rapid repair of energy systems.
• Sovereign CAT bonds are often facilitated by multilateral development banks and regional pools, with notable examples including Mexico's coverage of up to USD 485 million, Chile's USD 630 million earthquake coverage, and Jamaica's USD 185 million for named storms.
• The Pacific Alliance MultiCat Bond (2018) provided USD 1.36bn in coverage distributed among Chile (USD 500 million), Colombia (USD 400 million), Mexico (USD 260 million), and Peru (USD 200 million).
• A primary challenge in CAT bond uptake is the trade-off in trigger design: parametric triggers allow for very fast payouts but introduce 'basis risk', where the payout may not fully match actual losses.
