Insights

Debt capital markets analyst

SQM raises UF 10M in long-dated hybrid bonds to refinance debt.

SQM has issued local Series S hybrid bonds totaling UF 10,000,000 (about US$430 million) under a 35‑year Chilean bond program. The bonds are denominated in UF, a Chilean inflation-indexed unit, and pay a fixed annual interest rate of 4% starting on November 15, 2025.

The effective placement rate of 3.84% reflects a 1.52% spread over a Central Bank of Chile UF bond of similar maturity, giving a sense of how the market is pricing SQM’s long-term credit risk. The final maturity on February 15, 2058 adds very long-dated funding to the company’s capital structure.

Proceeds are earmarked for general corporate purposes and refinancing existing debt, so the net effect is more about reshaping the debt profile than changing overall leverage. Subsequent company disclosures may clarify how much shorter‑term or higher‑cost debt is replaced by this new hybrid issuance.
