Definitions and sources
Trade adds both directions. Shares refer to the country’s total goods exports; investment is an accumulated stock, not an annual flow. Every figure retains the currency and period of its source. BEA positions are historical-cost estimates based on the immediate counterpart, not market values or investment by ultimate owner. ‘More than’ indicates a lower bound, not an exact amount. A recorded stock does not establish new activity or authorisation to operate under sanctions.

Definitions, dates and sources
Blank cells are not zero. Average annual inflation and the latest year-on-year figure appear in separate rows: they are not the same measure. Every annual indicator retains its reference year; when the years differ, the figures are identified as not directly comparable. When a figure is unavailable from the World Bank, an annual IMF estimate is used and identified as such. The latest year-on-year figure is the latest official release verified as of 7 October 2026. This includes advance releases marked as provisional. Mexico may have a fortnightly figure before the full month is published; it is not automatically compared with a monthly figure. The publication date is retained in each source’s details; it does not replace the observation period or the annual average. Policy rates carry their own dates and represent different instruments. Spain and France share the ECB rate. Balances are positive for surpluses and negative for deficits. The IMF may use fiscal years; unemployment retains each source’s definition (ILO estimates, IMF WEO or PCBS), as stated in the details. For Palestine, debt and the fiscal balance cover central government and retain the PCBS definition; they are not presented as consolidated general government. These are economic magnitudes, not measures of relationship quality.
Area retains each source’s territorial coverage; it does not determine sovereignty or effective control. Canada uses an archived national geographic reference. Military expenditure retains the 2024 SIPRI sample distributed by the World Bank: the amount and percentage of GDP use that same definition, which differs from NATO’s. It is not an approved budget or a 2026 figure. Information from the Stockholm International Peace Research Institute (SIPRI). Military expenditure database · Terms of use0

Connections between people
The existence of communities in both countries is a tie noted during the visit. No resident population or annual flow of tourists or students can be inferred from that statement. [1]

What each figure measures
Residents are counted by nationality and the coverage of the stated register, not as people born in the other country or as new arrivals in one year. PERE includes dual nationals and people born outside Spain. Study with OPT and stays carrying academic credit are different measures. Travel may include several visits by the same person; FRONTUR arrivals require an overnight stay, whereas the Canadian survey includes day visits. These figures are neither added together nor automatically compared across directions.

Underlying ties
History, institutions and long-standing issues.
The scale of both economies
Nominal GDP for Portugal is 346.6 billion USD (2025), compared with 0.981 for São Tomé & Príncipe (2025). The reference populations are 10.8 and 0.24 million, respectively. In the same year, the economy of Portugal was 353.25 times that of São Tomé & Príncipe in nominal GDP. The comparison provides context on market size, but does not, on its own, measure influence, well-being or diplomatic closeness. Estimates and their sources retain their labels in the tables.

Recent developments
Recent developments and latest available data · Review: 2026-10-08
Bilateral context
Prime Minister Luís Montenegro attended Carlos Vila Nova's inauguration in São Tomé on 3 September 2026. In that context he highlighted financial cooperation and ties in education, health and energy. [1]
Cooperation and bilateral issues
His remarks also highlighted Portuguese communities in the archipelago and São Toméan communities in Portugal, without publishing a comparable count of residents. Both countries' participation in the CPLP provides a multilateral framework distinct from bilateral agreements. Montenegro reported talks to organize a summit that could expand cooperation and encourage Portuguese business investment. That summit is presented as a possibility under preparation, not as a meeting already held or contracts already awarded. The official visit is the documented event; the announced priorities retain their programmatic nature. [1]
What merchandise trade shows
In 2025, merchandise trade between the two countries (Portugal and São Tomé & Príncipe) totalled 74.1 million current USD. Shipments from the first to the second were 73 million; those in the opposite direction, 1.2 million. The difference between the two flows was 71.8 million, in favour of Portugal. This is a goods balance, not the total balance of the economic relationship: it excludes services, income and transfers. Both directions come from a single customs reporter to avoid adding mirror records. [2]
The partner's share of exports
Sales from Portugal to the partner represented 0.0815% of its worldwide goods exports in 2025. The share compares the same reporter, year and coverage. It measures export concentration, not the percentage of GDP dependent on this relationship. A partner may be important in a specific sector even if its share of total goods trade is small. [2]
Five years of trade trends
The consistent series shows 70.1 million USD in 2021 and 74.1 million in 2025. The change between the two endpoints was +5.8 % in current dollars. The highest annual value in the period was recorded in 2025, at 74.1 million. The chart allows the two directions to be compared to see whether they moved together or differently. The change combines quantities, prices and exchange rates; it is not automatically attributed to a treaty, a visit or a political decision. The same reporter is retained and missing years are not interpolated. [3]
Documented trade sectors
Within the selected chapters, electrical and electronic equipment stands out in shipments from Portugal to São Tomé & Príncipe, at 5.5 million USD in 2025. Within the selected chapters, machinery and mechanical appliances stands out in shipments from São Tomé & Príncipe to Portugal, at 0.0294 million USD in 2025. The table compares eight selected chapters with the same coverage as the trade total. It is not a complete list or proof that the first item in this selection is the leading product across the entire relationship. A chapter groups numerous goods: machinery and components, for example, do not describe a single business transaction. [4]
