The noodle bowl effect describes the proliferation of overlapping free trade agreements (FTAs) in the Asia-Pacific region, each with its own rules of origin, tariff schedules, phase-in timelines, and dispute mechanisms. The term was popularized by economist Masahiro Kawai and Ganeshan Wignaraja in work published through the Asian Development Bank Institute in the late 2000s, as an Asian counterpart to Jagdish Bhagwati's earlier "spaghetti bowl" metaphor (coined in 1995) describing similar tangles among Western preferential agreements.
The core problem is administrative and economic. When a single exporter—say a Thai auto-parts manufacturer—can ship under ASEAN, ASEAN-China, ASEAN-Japan, ASEAN-Korea, ASEAN-India, ASEAN-Australia-New Zealand, or various bilateral FTAs, each agreement may define "originating goods" differently. Firms must choose which preference to claim, document compliance, and absorb legal costs. Studies by ADB and ERIA have repeatedly found that FTA utilization rates in Asia remain low, particularly among small and medium enterprises, partly because of this complexity.
The noodle bowl is often cited as a rationale for consolidating agreements into broader regional frameworks. The Regional Comprehensive Economic Partnership (RCEP), signed in November 2020 and entered into force on 1 January 2022, was explicitly designed in part to harmonize rules of origin across its 15 member economies. The earlier Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), in force from December 2018, pursued a similar consolidation logic among its 11 original signatories.
For MUN delegates and trade researchers, the noodle bowl is a useful diagnostic concept in debates on:
- WTO most-favoured-nation erosion and Article XXIV GATT exceptions
- Development gaps in FTA utilization between large firms and SMEs
- Arguments for "multilateralizing regionalism"
- Supply-chain resilience and rules-of-origin reform
The metaphor remains contested: some economists argue overlapping FTAs still expand trade on net, even if inefficiently.
Example
In a 2010 ADBI working paper, Kawai and Wignaraja argued that East Asia's "noodle bowl" of more than a dozen overlapping FTAs was raising transaction costs for exporters and justified pursuing a region-wide agreement.
Frequently asked questions
Both describe overlapping trade agreements, but 'spaghetti bowl' (Bhagwati, 1995) referred mainly to Western and global preferential deals, while 'noodle bowl' applies the same critique specifically to the dense web of Asian FTAs that emerged in the 2000s.
