Seychelles holds no commercial mineral or metal endowment and no domestic oil or gas production. It is a granitic and coralline archipelago with only domestic-scale construction aggregate, sand and quarrying; USGS Mineral Commodity Summaries and BGS World Mineral Statistics carry no meaningful Seychelles production entry. Petroleum is entirely imported. Installed generation capacity is approximately 129 MW, predominantly heavy fuel oil and diesel through the Public Utilities Corporation, with over 90 per cent of electricity fossil-fuel generated despite full electrification. Renewable assets are the 6 MW Port Victoria Wind Farm (eight 750 kW turbines, commissioned 2013) and the 5 MW Île de Romainville solar array with 3.3 MWh of storage (commissioned 2021), against a national target of 15 per cent renewables by 2030.
The endowment that matters is fisheries. The maritime economic zone spans 1.3 to 1.37 million square kilometres. The 2023 Indian Ocean yellowfin quota allocated to Seychelles was 37,782 tonnes, of which 34,028 tonnes were consumed across purse-seine, industrial and semi-industrial longline fleets, with 13 Seychelles-flagged purse seiners operating at an average allocation of roughly 2,500 tonnes per vessel. On that resource sits the Indian Ocean Tuna cannery at Port Victoria, one of the largest tuna processing facilities globally: 40 per cent Government of Seychelles and 60 per cent Thai Union, approximately 1,800 employees and the largest single employer in the country, with processing capacity raised from 50 tonnes per day in 1995 to 335 tonnes per day and average output of 1.5 to 2 million cans per day. Programme data, to be treated as indicative, attributes 95 per cent of Seychelles' manufacturing exports and 88 per cent of exports to the European Union to this single facility. Port Victoria is also one of the world's major tuna transhipment ports, with 387,992 metric tonnes of tuna unloaded in 2021, though most transhipped tuna is a throughput flow rather than domestic production.
The comparative-advantage picture is correspondingly concentrated. Canned tuna under HS 160414 alone accounted for USD 253.1 million of USD 547.8 million in total goods exports in 2023 (37,226,400 kg), roughly 46 per cent of all goods exports, giving a very high revealed comparative advantage in a single line. Minor secondary advantage exists in cannery byproducts: fishmeal and animal fodder at USD 7.5 million and fish oils at USD 3.7 million in 2023. Seychelles is not published in either the Harvard Growth Lab Atlas of Economic Complexity or the OEC trade-based ECI rankings, both of which exclude it for insufficient trade-data coverage; that exclusion is itself diagnostic of an extremely undiversified export structure. The realistic product-space adjacency is incremental further food and fish processing, such as tuna loins, pouches and value-added ready meals, a low-to-moderate complexity step. The mechanism of advantage is the combination of anchor foreign investment by Thai Union, EU preferential duty-free market access under the EPA, the EEZ tuna resource and transhipment-port agglomeration at Victoria.
The endowment in depth
Seychelles is a granitic and coralline archipelago with no commercial mineral or metal production. USGS Mineral Commodity Summaries, the USGS Minerals Yearbook and BGS World Mineral Statistics carry no meaningful Seychelles production entry; only domestic-scale construction aggregate, sand and quarrying exists. The 2023 export line "iron or steel scrap" (USD 38.9 million, 7.1% of exports) is recycled scrap collection and re-export rather than mineral production — it spiked 2,687% over 2022 and is a one-off salvage and clearance flow. On energy, there is no domestic oil or gas production; offshore acreage has been licensed historically with no commercial discovery, and petroleum is entirely imported. Installed generation is approximately 129 MW, predominantly heavy fuel oil and diesel via the Public Utilities Corporation, and over 90% of electricity is fossil-fuel generated despite 100% electrification. Renewables are limited to the 6 MW Port Victoria Wind Farm (eight 750 kW turbines; UAE-funded, ~USD 28 million; commissioned 2013), the 5 MW Île de Romainville solar PV with 3.3 MWh storage (2021, Masdar/ADFD), and a salt-water floating PV project (Seysun Lagoon, ~5.8 MWp, Qair) under development, against a national target of 15% renewables by 2030. The USD 194 million "mineral fuels including oil" export line (35.4% of 2023 exports) is overwhelmingly bunker-fuel re-export and ship refuelling at Port Victoria, not domestic production, and must be excluded from any read of genuine productive capacity.
Fisheries is the endowment. Seychelles is one of the world's most tuna-dependent economies, with per-capita fish consumption around 65 kg/year (indicative), an EEZ of 1.3–1.37 million km², and a 2023 Indian Ocean yellowfin quota of 37,782 tonnes, of which 34,028 tonnes were consumed across purse-seine, industrial and semi-industrial longline fleets; 13 Seychelles-flagged purse seiners operate at an average ~2,500 t/vessel allocation. 2023 was an off-year, with El Niño and a deeper thermocline cutting EEZ catchability roughly 40%, after an exceptional 2022 (+170% over 2021). The Indian Ocean Tuna (IOT) cannery at Port Victoria — 40% Government of Seychelles, 60% Thai Union — is one of the largest tuna processing facilities globally, employing ~1,800 people (the country's largest single employer), with processing capacity raised from 50 t/day (1995) to 335 t/day and average output of 1.5–2 million cans/day; it accounts for 95% of manufacturing exports and 88% of exports to the EU. Port Victoria is also one of the world's major tuna transhipment ports, with 387,992 MT of tuna unloaded in 2021 (93% of that year's total landing and transhipment, +16% on 2020), though most transhipped tuna is a throughput flow rather than Seychelles domestic production. Cannery byproducts include fishmeal and animal fodder (USD 7.5 million, 1.4%) and fish oils and fats (USD 3.7 million, 0.7%) in 2023.
Agriculture is tiny and import-dependent, with over 90% of food and production inputs imported. Heritage crops are negligible at scale: Ceylon true cinnamon (Cinnamomum verum) is genuine and historically central, but production fell to about 0.2 tonnes in 2022 and the modern industry is a remnant (EU cinnamon exports averaged roughly 30 tonnes/year, 2013–2021, under the EPA); copra and coconut, vanilla and Seychelles tea exist mainly for the domestic and tourist market, and forestry is negligible. Manufacturing value added was about 4.17% of GDP in 2024, down from 4.69% in 2023, yet on a per-capita basis MVA exceeds USD 200 — among the higher levels in sub-Saharan Africa — reflecting the cannery's outsized weight. Actual manufacturing is overwhelmingly canned tuna and fish processing, plus small-scale beverages (Seybrew beer, soft drinks), tobacco, paints, baked goods and light consumer goods for the domestic market. The Providence Industrial Estate on Mahé is the main industrial site, damaged by a 2023 explosion that dampened 2024 activity.
Human capital is a small, high-literacy, high-income labour force with GDP per capita around USD 17,900 — the highest in Africa — but high wage and energy costs are a genuine competitiveness constraint, and the cannery relies heavily on expatriate and migrant labour. Specialised skills concentrate in fisheries, maritime, tourism and hospitality, and offshore finance, supported by the University of Seychelles and the Seychelles Maritime Academy. Infrastructure centres on Port Victoria, the only deep-water port and the dominant Indian Ocean tuna transhipment and fleet-servicing port, handling about 95% of national imports; container throughput is a modest ~140,000 TEU annually, with planned expansion to 218,000 TEU under the Port Victoria Expansion and Rehabilitation Project (PVERP), financed by an EIB/AFD loan of about €29 million plus a ~€5 million EU grant (total ~€36.65 million). Seychelles International Airport on Mahé provides air connectivity. The binding constraint is remoteness — roughly 1,500–1,600 km from the East African coast, carrying an estimated ~20% higher sea-freight cost than Southeast Asian competitors — which must be weighed against the "maritime hub" framing.
Economic complexity & comparative advantage
Seychelles is not published in either the Harvard Growth Lab Atlas of Economic Complexity or the OEC trade-based ECI rankings; both exclude it for insufficient trade-data coverage, and the OEC 2022 table marks Seychelles "No data" for trade ECI. That exclusion is itself diagnostic of an extremely undiversified, concentrated export structure. Revealed comparative advantage is overwhelmingly in prepared and preserved tuna: canned tuna (HS 160414) alone was USD 253.1 million of USD 547.8 million total goods exports in 2023 (37,226,400 kg) — roughly 46% of all goods exports — giving a very high RCA in a single line, with only minor possible RCA in the cannery byproducts fishmeal (HS 2301) and fish oils (HS 1504).
Because no Atlas profile exists, feasible diversification adjacencies are not flagged. Product-space logic suggests the only near-adjacencies are further food and fish processing — tuna loins, pouches and value-added ready-meals — a low-to-moderate complexity step from the current finished-goods position. This is itself the diagnostic: an economy whose entire complexity read reduces to one processing chain shows little revealed capability to redeploy into more complex products.
The trump card · the single strongest continental position
Canned and prepared tuna (HS 1604 / 160414) is Seychelles' single strongest, most defensible continental supply position — and essentially its only one. Canned tuna exports reached USD 253.1 million in 2023 (Comtrade/WITS), about 46% of all goods exports; the IOT cannery is one of the largest tuna processing facilities in the world, producing 1.5–2 million cans/day at 335 t/day capacity and accounting for 95% of national manufacturing exports. It combines a real resource (EEZ tuna), genuine finished-goods processing, very high revealed comparative advantage and a shelf-stable consumer product — beneficiation that already sits at the top of the ladder. The mechanism of advantage — Thai Union anchor investment, EU duty-free access under the EPA, EEZ stock, and transhipment-port agglomeration at Victoria — is genuinely durable.
The limits are equally real. The position carries a ~1,500–1,600 km remoteness penalty of roughly 20% on sea-freight versus Asian competitors; it depends on a single investor in Thai Union and on EU preferential access, to which ~88% of exports currently flow; and it faces a premium-species mismatch, since Africa's mass market imports cheaper canned mackerel, sardine and pilchard rather than premium tuna. High domestic wage and energy costs and reliance on imported inputs — cans, aluminium, packaging — compound the exposure. The runners-up drop off sharply: fishmeal and animal fodder (HS 2301) and tuna fish oil (HS 1504) are genuine cannery byproducts with real but tiny volumes (USD 7.5 million and USD 3.7 million in 2023), and the Port Victoria transhipment and fleet-servicing hub is a services position rather than a goods supply. After canned tuna, there is no second goods category at continental scale.

Current reality
Seychelles is a high-income services-and-fisheries micro-economy of roughly 122,730 people, with total GDP of approximately USD 2.1 billion and GDP per capita near USD 17,900, the highest in Africa. Tourism accounts for 31 per cent of GDP and 41 per cent of exports. Manufacturing value added was about 4.17 per cent of GDP in 2024, down from 4.69 per cent in 2023, though on a per-capita basis manufacturing value added exceeds USD 200, placing Seychelles among the higher-MVA-per-capita sub-Saharan economies, a figure that reflects the cannery's outsized contribution. What is actually manufactured beyond fish processing is small-scale beverages, tobacco, paints, baked goods and light consumer goods for the domestic market, concentrated at the Providence Industrial Estate on Mahé, which was damaged by a 2023 explosion that dampened 2024 activity.
Total goods exports in 2023 were USD 547.8 million, on a multi-year declining trend of minus 35.2 per cent against 2019. The composition was canned tuna at USD 252.9 million (46.2 per cent), mineral fuels as bunker re-export at USD 194 million (35.4 per cent), iron and steel scrap at USD 38.9 million (7.1 per cent), frozen and fresh whole fish at USD 29.6 million (5.4 per cent), fishmeal at USD 7.5 million and fish oils at USD 3.7 million. Destinations are overwhelmingly European, with the canned-tuna market concentrated in France, the United Kingdom, Italy and Spain. Only about 2.5 per cent of Seychelles' exports by value went to Africa in 2023, with Côte d'Ivoire at 1.4 per cent the main African destination. Continental supply is therefore a real change from current trade patterns rather than an extension of them. Port Victoria is the only deep-water port and handles roughly 95 per cent of national imports, with modest container throughput of about 140,000 TEU annually and planned expansion to 218,000 TEU under a project financed by an EIB and AFD loan of about EUR 29 million plus a EUR 5 million EU grant, some EUR 36.65 million in total.
