▣ DATA BRIEF · ASEAN TRADE
☀ Key Stats
◆ Only about 22% of ASEAN exports went to other ASEAN members in 2024, compared with 61% of European Union exports staying within the EU.
◆ The EU’s within-bloc export share was therefore nearly 2.8 times ASEAN’s.
◆ The 11 ASEAN economies together form a roughly $4.5 trillion economy with about 700 million people.
◆ The region was growing at more than 4.5% annually, according to the IMF Finance & Development analysis.
◆ Foreign direct investment into ASEAN reached $244 billion in 2025, up 10% from the previous year.
◆ Manufacturing investment increased by nearly 50% in 2025.
◆ IMF calculations suggest reducing regional nontariff barriers could raise ASEAN real output by a cumulative 4.3% over the long run.
◆ The projected 4.3% output gain is equivalent to more than one-third of Malaysia’s current economy, according to the analysis.

Only about 22% of exports from the Association of Southeast Asian Nations go to other members of the bloc, compared with 61% within the European Union, according to a new analysis in the IMF’s Finance & Development magazine.
The gap is striking because ASEAN is already one of the world’s most internationally connected regions, encompassing an economy of roughly $4.5 trillion and about 700 million people.
Much of Southeast Asia’s trade instead continues to connect factories in the region with customers elsewhere in the world.
IMF calculations suggest that reducing barriers between ASEAN economies could raise the bloc’s real output by a cumulative 4.3% over the long run.
◎ HEADLINE COMPARISON
22% vs. 61%
Share of exports staying within ASEAN compared with the European Union in 2024.
The EU keeps nearly three times more exports inside its bloc
The comparison measures the share of each bloc’s exports that go to fellow member economies rather than destinations elsewhere in the world.
For ASEAN, that share was a trade-weighted average of about 22% in 2024.
The comparable EU figure was 61%, a difference of 39 percentage points.
Put another way, the EU’s internal export share was almost 2.8 times as high.

The gap remains large even though several ASEAN members rank among the world’s most trade-dependent economies.
Singapore and Vietnam are highlighted in the IMF analysis as particularly open economies that nevertheless direct relatively little of their exports to nearby ASEAN markets.
↳ A SHARED PRODUCTION NETWORK, NOT YET A SHARED MARKET
Much of the trade inside ASEAN feeds exports to the rest of the world
The relatively small internal share does not mean ASEAN economies are disconnected from one another.
Many are deeply integrated through manufacturing supply chains in which parts and components move between countries before finished products are exported elsewhere.
The IMF feature describes this as a region that has developed a shared production network without building an equally large shared consumer market.
That structure has supported Southeast Asia’s emergence as a major manufacturing base, but it also leaves regional growth more dependent on demand outside ASEAN.
ASEAN is already a $4.5 trillion economy
The internal-trade gap is particularly notable because of ASEAN’s scale.
Its 11 economies together generate about $4.5 trillion in economic output, which would make the bloc the world’s fourth-largest economy if treated as a single unit.
The region is home to roughly 700 million people and was growing at more than 4.5% annually, according to the Finance & Development feature.

The regional grouping now includes Brunei Darussalam, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, Vietnam and Timor-Leste.
Foreign investment reached $244 billion
The relatively weak internal export share has not stopped ASEAN from attracting large amounts of international capital.
Foreign direct investment reached $244 billion in 2025, an increase of 10%, according to UNCTAD data and calculations cited in the IMF feature.
Manufacturing investment increased by nearly 50%.
The analysis points to carmakers, semiconductor companies and electronics manufacturers expanding their presence as companies diversify global supply chains.
ASEAN’s share of global foreign direct investment has also increased substantially over the past two decades.
That makes the contrast more unusual: the region has become increasingly important to global manufacturers and investors while its own internal market remains relatively fragmented.
↳ MODELED OPPORTUNITY · REGIONAL INTEGRATION
Lower trade barriers could raise output 4.3%
The biggest economic number in the analysis concerns what could happen if ASEAN became more integrated internally.
IMF calculations suggest lower regional nontariff barriers could increase ASEAN’s real GDP by a cumulative 4.3% over the long run.
↗ LONG-RUN IMF ESTIMATE
+4.3%
Cumulative increase in ASEAN real GDP under deeper regional integration and lower nontariff barriers.
The feature says an increase of that size would be equivalent to adding more than one-third of Malaysia’s economy to regional output.
The figure is a modeled long-run estimate rather than a forecast of growth that will automatically occur.
Nontariff barriers remain part of the integration gap
Tariffs are only one form of friction between countries.
Nontariff barriers can include differing standards, licensing requirements, regulations, administrative procedures and other rules that increase the difficulty or cost of selling across borders.
Other analysis in the same IMF issue points to logistics limitations, uneven human-capital development and regulatory barriers as obstacles to deeper regional trade.
The issue argues that closer cooperation on services, digital trade, competition policy and common standards could further reduce the cost of doing business across borders.

✦ Why it matters ✦
ASEAN’s low internal export share matters because the region has become a major part of the global manufacturing system without developing an internal market on the scale of its economic footprint.
That leaves a large share of production dependent on customers elsewhere in the world.
During periods of strong global trade, that model can generate rapid growth by connecting Southeast Asian factories to large overseas markets.
But greater dependence on external demand can also leave the region exposed to tariffs, weaker overseas consumption and disruptions to global supply chains.
The 22% versus 61% comparison suggests there is substantial room for ASEAN economies to sell more to their own regional market.
Whether the bloc can capture the IMF’s modeled 4.3% long-run output gain will depend on how far countries actually reduce the barriers that continue to divide their markets.
The trade story also complements recent StatsJournalist coverage of global services exports, where Asia remained a major international exporter but grew more slowly than Europe in early 2026.
ⓘ How to read the findings
The primary source is a September 2026 Finance & Development “Picture This” analysis by Andrew Stanley, rather than an academic research paper. The accompanying graphics use data from ASEANstats, Eurostat, UNCTAD and the World Bank alongside IMF staff calculations.
The headline 22% and 61% figures refer specifically to the share of exports going to fellow bloc members in 2024. They are trade-weighted averages rather than the simple average of individual member-country percentages.
The comparison uses 11 ASEAN economies and the 27-member European Union. The two blocs differ substantially in income levels, institutions, geography, economic structure and the depth of political integration, so the EU figure should be treated as a benchmark rather than a directly achievable target for ASEAN.
The figures describe exports of goods within each bloc. They should not be interpreted as saying that only 22% of all economic activity in ASEAN takes place inside the region.
ASEAN’s internal trade is also heavily integrated through intermediate goods and production networks. A component can cross several borders before the finished product is ultimately sold outside the region.
The 4.3% GDP figure is a modeled cumulative long-run gain under lower regional nontariff barriers. It is not a forecast that ASEAN’s economy will grow an additional 4.3% next year or every year.
The short Finance & Development feature does not provide the full modeling specification behind the 4.3% estimate on the article page, so the figure should be presented as an IMF estimate rather than independently recalculated here.
The reported $244 billion in 2025 foreign investment and nearly 50% rise in manufacturing investment come from UNCTAD’s foreign-investment database and calculations cited by the Finance & Development author.
Finance & Development notes that opinions expressed in its articles do not necessarily represent IMF policy.
