National Oil Account

The Banco Central de São Tomé e Príncipe (BCSTP) administers the account. It is responsible for operations, custody, and public reporting, including the publication of macroeconomic projections and treasury-bill results on its website. No separate investment committee or external manager is disclosed.

Revenues flow from hydrocarbon production in the Nigeria–São Tomé and Príncipe Joint Development Zone, where proceeds are split 60% to Nigeria and 40% to São Tomé and Príncipe. The Agência Nacional do Petróleo (ANP-STP) manages the licensing and contractual framework for exploration blocks, while the BCSTP receives and accounts for the resulting income.

Chevron serves as operator and co-investor in JDZ Block 1. In the Exclusive Economic Zone, Kosmos Energy holds interests across multiple blocks, and Shell has invested in Blocks 6 and 11. These partnerships form the upstream basis for the account’s revenue stream.
