Inflation analysis
Inflation in Sao Tome and Principe
This page covers 31 years of Sao Tome and Principe consumer price data, from 1996 to 2026. Series that begin this late usually do so because the country, the currency or the statistical agency behind the index did not exist in its current form before then. The steepest single year on record was 1998, when consumer prices in Sao Tome and Principe rose 50.5%. A rate that high compounds brutally: at that pace money loses about half its value every two years.
Prices have not fallen across a full year once in the 30 years recorded here. Every year on this page moves in the same direction, which is why an amount of money always buys less later than earlier. By decade, the 2000s were the most inflationary stretch, averaging 16.2% a year, while the 2010s were the calmest at 8.5%. Over the last ten years inflation has averaged 11.4% a year, below the 14.6% average across the whole record.
