The world’s largest free trade agreement has been in force for three years. It covers 30% of global GDP and 2.3 billion people. It includes China, Japan, South Korea, Australia, and all ten ASEAN nations.
Most investors have never once checked a data source for it.
RCEP — the Regional Comprehensive Economic Partnership — entered into force on January 1, 2022. In terms of raw numbers, it is the largest trade agreement in history: 15 member countries, combined GDP of approximately US$26 trillion, a population of 2.3 billion. The closest comparables are the EU (US$17 trillion, 450 million people) and USMCA/NAFTA (US$29 trillion, 490 million people). RCEP exceeds both in population and at minimum matches in economic weight.
And yet the investor class has treated it like a press release rather than a market-moving event. This is a mistake.
The reason RCEP gets underweighted in investment analysis is its gradualism — tariff reductions are scheduled over 10 to 20 years, not overnight. A new FTA that triggers immediate tariff elimination generates headlines and commodity price movements. RCEP’s design is deliberate and slow: it’s infrastructure, not a catalyst. But infrastructure compounds. And the RCEP infrastructure is already reshaping supply chains in ways that will become legible in corporate earnings over the next five years.
The RCEP negotiation began in 2012, at the ASEAN Summit in Phnom Penh, Cambodia. The ambition was to create a framework that unified ASEAN’s five existing bilateral FTAs — with China (ACFTA), Japan (AJFTA), South Korea (AKFTA), Australia-New Zealand (AANZFTA), and India (AIFTA) — into a single, coherent regional trade architecture.
Thirteen years of negotiation. Seven working groups. The near-collapse of the entire deal when India pulled out in November 2019. Final signing at a virtual ASEAN Summit in November 2020 — without India, and during a pandemic, with minimal fanfare.
ASEAN’s role in creating RCEP was central and deliberate. ASEAN operates on consensus, and ASEAN centrality is written into RCEP’s governance structure — the agreement is technically an ASEAN-led initiative, with ASEAN as the hub around which the other major economies (China, Japan, South Korea) connected. This is not a China-dominated agreement, despite Western narrative tendencies to frame it that way. Japan and South Korea are full participants with equal rule-making status.
The core of RCEP is tariff liberalisation. Member countries agreed to eliminate tariffs on at least 90% of goods categories within 20 years of the agreement entering into force. The specific schedules vary by country and product category — some sectors see immediate elimination, others phase in over 5, 10, 15, or 20 years.
For ASEAN-China trade: many categories were already largely tariff-free under the ASEAN-China FTA (ACFTA, in force since 2005). RCEP adds value at the margin through better rules of origin, investment rules, and the new Japan-China and South Korea-China bilateral trade provisions (neither Japan nor South Korea had a bilateral FTA with China before RCEP).
The Japan-China dimension is historically significant. RCEP is the first time Japan and China have been in a free trade agreement together. The tariff schedule between Japan and China covers 86% of goods (below the 90% RCEP target, given specific sensitivities in agriculture and automotive). But it creates a legal framework for Japan-China trade that did not previously exist. Japan-China bilateral trade in 2023 was approximately US$284 billion (Observatory of Economic Complexity) — even marginal tariff reductions generate significant savings at that volume.
The rules of origin provision is the most practically important for supply chain structuring. RCEP allows a manufacturer to use inputs from any RCEP member country and still qualify for preferential tariffs when exporting to another RCEP member. This is called “cumulation” — and it dramatically expands the flexibility of regional supply chain design.
Practical example: A Vietnamese garment manufacturer can source fabric from China, zippers from Japan, and buttons from South Korea — all under RCEP cumulation. The finished garment, when exported to Australia (an RCEP member), qualifies for preferential tariff treatment because all inputs originated in RCEP countries. Under the previous bilateral FTA framework, each input sourcing decision had to individually comply with origin rules, creating administrative complexity.
China-ASEAN trade reached US$911 billion in 2023 (Ministry of Commerce of China, MOFCOM data) — a record. This makes ASEAN China’s largest trading partner bloc for the fourth consecutive year, ahead of the EU, the US, and Japan.
The RCEP contribution to this is not cleanly separable from other factors (the US-China trade war diversion, COVID supply chain restructuring, natural trade growth). But the directional correlation is consistent: every major RCEP trade corridor showed above-trend growth in 2022 and 2023.
Japan’s trade with ASEAN grew approximately 12% in 2023 in USD terms. Japan’s FDI into ASEAN reached a record US$23 billion in 2023 — manufacturing investments (particularly in Vietnam, Thailand, and Indonesia) driven partly by RCEP-enabled supply chain restructuring. South Korea’s ASEAN trade exceeded US$200 billion in 2023 for the first time.
The most direct RCEP beneficiary by supply chain logic: Vietnam. Vietnam sits at the intersection of Chinese manufacturing input supply and RCEP preferential export access to Japan, South Korea, and Australia. Samsung manufactures 50% of its global smartphone volume in Vietnam. LG manufactures OLED TV panels in Vietnam. These supply chains are RCEP-optimised: Chinese components, Vietnamese assembly, RCEP tariff on exports to Australia and Japan.
The “world’s largest FTA” framing overstates RCEP’s immediate impact in two ways.
First, the tariff reduction schedules are very gradual. The most sensitive product categories — agricultural goods, textiles, automotive — are either excluded entirely or on 20-year phase-in schedules. For the first decade of RCEP’s life, the tariff impact for many industries is minimal. Businesses making supply chain decisions on 3–5 year planning horizons will only begin to feel the full tariff benefit in 2030+.
Second, non-tariff barriers dominate. Regulatory differences, customs procedures, sanitary and phytosanitary standards, technical barriers to trade — these are the actual friction points for intra-ASEAN trade, and RCEP’s provisions in these areas are notably weaker than the tariff chapters. A Thai food exporter selling to Japan still navigates Japan’s complex food labeling and certification requirements. RCEP didn’t simplify those. ASEAN’s intra-bloc trade as a percentage of total ASEAN trade has barely moved in a decade — still approximately 22%, compared to 65% for the EU. Tariff reduction without regulatory harmonisation has a ceiling.
Third: India’s absence is a strategic gap. India-ASEAN trade is significant (~US$130 billion in 2023). India’s re-entry into RCEP discussions (which the Modi government has begun exploring since 2024) would dramatically alter RCEP’s economic weight and strategic significance. But re-entry negotiations, if they begin, would take years.
The investment implication of RCEP is not a direct trade — it’s a framework for identifying which companies benefit from the underlying supply chain regionalisation that RCEP enables.
RCEP beneficiary profiles: companies with ASEAN manufacturing facilities that source Chinese inputs. Companies in Japan or South Korea that want to reduce their China manufacturing concentration while staying within the RCEP rules of origin framework (Vietnam and Thailand are primary alternatives). Australian commodity exporters (iron ore, agricultural products) that sell to RCEP members — their export pathway is now governed by a more favorable and certain tariff framework.
ETF exposure: ASEAN equity ETFs provide the broadest access. The SPDR S&P Emerging Asia Pacific ETF (GMF) or iShares Core MSCI Pacific ex-Japan ETF have significant ASEAN weighting. Country-specific: EWS (iShares MSCI Singapore ETF), EWM (iShares MSCI Malaysia ETF), THD (iShares MSCI Thailand ETF). Vietnam-specific: VNM (VanEck).
For active stock selection: the RCEP trade thesis most clearly applies to:

India’s potential re-entry is the biggest variable. RCEP with India would add approximately US$3.7 trillion to the agreement’s combined GDP and 1.4 billion people. It would create a genuine supranational economic bloc competing with the EU and USMCA in strategic significance. India’s commerce ministry began informal RCEP re-engagement conversations in 2024 under Trade Minister Piyush Goyal, though no formal negotiating mandate has been announced.
The second evolution: RCEP’s investment chapter will become more practically significant as implementation deepens. The chapter establishes MFN (Most Favored Nation) treatment and national treatment obligations for RCEP member investors — meaning a Malaysian company investing in Vietnam gets the same legal protections as a Vietnamese company. This accelerates ASEAN intra-bloc FDI, which has historically been constrained by weaker bilateral investment treaty networks.
Third: the ASEAN Digital Economy Framework Agreement (DEFA), being negotiated in parallel to RCEP’s digital provisions, could significantly enhance RCEP’s value for the services sector — which RCEP largely excludes. If DEFA concludes successfully, RCEP + DEFA together create a combined goods and services liberalisation framework that begins to approximate an ASEAN single market in practical terms.
RCEP is not a news story. It is a structural shift in the rules that govern how one-third of the global economy trades with itself. The companies and investors who have understood this framework and positioned within it since 2022 are three years ahead of those who are reading about it now.
The three years of data say the positioning is working. The question is whether you’re in it.
