Sao Tome and Principe

Official risk classification

The CRC scores the likelihood a country services its external debt on an eight-step scale, from 0 to 7, and sets the minimum premiums the OECD Arrangement participants charge on officially supported export credit. Categories 1 to 7 are the risk ladder (1 lowest, 7 highest). Category 0, and the blank status the OECD has used for these countries since 2013, mark high-income OECD and high-income euro-area economies that are exempt because their credit is priced on market terms. An exempt status is unclassified by design, not a data gap and not a zero-risk rating.

Debt trajectory, 1980 onward

Debt to GDP by perimeter, observed years only (no IMF forecast years). Central-government debt is mechanically below general government (it excludes state, local and social-security debt). No sovereign-debt crisis years fall in this window.

Debt profile

External debt (World Bank IDS)

External debt owed to non-residents, from the World Bank’s International Debt Statistics, which covers low- and middle-income economies only (Sao Tome and Principe is classified Lower middle income). Dollar figures are current US dollars; ratio figures are percentages, as labelled. This is external debt in USD, a different measure from the government debt-to-GDP ratios above; do not compare the two directly.

Debt in default (BoC-BoE CRAG)

Stock of Sao Tome and Principe’s government debt in default in 2024, from the Bank of Canada–Bank of England Sovereign Default Database, broken down by creditor class. The external total is $111.0M (current US dollars, excluding domestic arrears, matching the database’s published headline). A further $4.0M of domestic (fiscal) arrears is tracked separately and is not included in that total.

In default (external) for 42 distinct years between 1983 and 2024. Peak external default stock: $276.0M.

Sovereign-debt crisis history

No sovereign-debt crisis is recorded for Sao Tome and Principe in the five chronologies (banking or currency crises, if any, are on the full crisis page).

Restructuring history and creditor losses

Every recorded Sao Tome and Principe sovereign-debt restructuring and the creditor loss (“haircut”) it imposed. The preferred haircut is the present-value measure (Sturzenegger–Zettelmeyer methodology); the face-value column is the headline principal write-down. Amounts restructured are in current US dollars. A crisis link appears where the restructuring year falls inside one of the sovereign-debt crisis episodes above.

Reading this profile

• Debt levels mix perimeters. The headline and debt-at-start figures fall back through IMF general government, then central government, then WEO gross debt, then (before 1980) the GMD historical series. Central-government readings understate the general-government ratio.
• Crisis flags end in 2016 (Reinhart-Rogoff) and 2017 (GMD, Laeven-Valencia), while debt runs to 2024. “Years since last crisis” and the absence of recent crises reflect where the sources stop, not a guarantee of calm.
• Debt level is a weak predictor of default on its own; see the methodology for the debt-intolerance evidence and the full construction.
