This entry sits under policy-finance index as the international rule-book that constrains Japan’s official export credit and investment support stack. Read it against NEXI for the Japanese insurance institution constrained by Arrangement minimum premia / tenor caps; with NEXI export-credit insurance products for product-side detail on Arrangement-compliant cover; with Jbic for the Japanese direct lender constrained by Arrangement-compliant lending terms; with JBIC overseas-investment underwriting process for the lender-side flow operating within Arrangement ceilings; with JOGMEC for upstream equity activity which sits outside Arrangement scope (equity is not export credit); with JOGMEC equity and offtake mechanics for the upstream-finance leg that often precedes Arrangement-disciplined downstream financing; with JICA for the ODA-grade lane that is explicitly outside Arrangement scope; with Japan policy finance system for the wider toolkit; with Japan policy-finance institution mandate matrix for the nine-institution comparison; with Japan project finance stack diagram for layered project-finance stack visualization; with Japan Eximbank history for the institutional history showing how Japan’s ECA framework evolved alongside the Arrangement; and with JETRO vs NEXI vs JBIC for the trade-promotion / insurance / financing three-pillar comparison.

TL;DR

The OECD Arrangement on Officially Supported Export Credits (commonly “OECD Arrangement” or “OECD Consensus”) is the international rule-book governing officially supported export credits with repayment terms of two years or more. It is administered by the OECD Trade and Agriculture Directorate via the Participants to the Arrangement group, but operates as a Gentleman’s Agreement — legally non-binding among participants but politically and administratively enforced through the OECD’s notification and review process. The framework sets four core disciplines: (1) maximum repayment tenor (varies by sector and country category — generally up to 8.5-10 years for Category I countries, 10 years for Category II countries, modified upward by Sector Understandings for ship / aircraft / renewables / nuclear / climate); (2) minimum premium rates (MPR) keyed to OECD’s Country Risk Classification (CRC) scale (0 = lowest risk to 7 = highest risk); (3) minimum interest rates (the Commercial Interest Reference Rates / CIRRs system for fixed-rate official lending); and (4) good-governance disciplines (anti-bribery, environmental and social due diligence, debt sustainability for low-income countries). Five active Sector Understandings modify general terms: Ship Sector Understanding (SSU), Aircraft Sector Understanding (ASU), Nuclear Power Sector Understanding (NSU), Climate Change Sector Understanding (CCSU), and the Coal-Fired Electricity Generation Sector Understanding (CFSU) — with the 2021 Coal Sector Understanding tightening (effectively prohibiting most new unabated coal-fired power export finance among participants) being a structurally significant climate-policy outcome. Eleven participants: Japan, the EU (27 member states represented as a bloc), the United States, the United Kingdom, Canada, Korea, Australia, New Zealand, Norway, Switzerland, and Türkiye. The Arrangement does not include China, Russia, India, Brazil, or any non-OECD state finance — which is the structurally important asymmetry shaping competition in 2020s strategic-finance contexts (semiconductors, critical minerals, infrastructure in emerging markets, hydrogen / ammonia supply chain). 2023-2025 saw the most significant Arrangement reform since the 2009 Tokyo Action Statement: the CCSU 2023 modernisation (expanded climate-friendly tenor up to 22 years for many renewables / hydrogen / ammonia / CCS / certain rail metro), the CFSU 2021 restricting coal-fired generation finance, and continuing debate on a possible Critical Minerals Sector Understanding.

Participants	11: Japan, EU (27 member states), US, UK, Canada, Korea, Australia, New Zealand, Norway, Switzerland, Türkiye
Non-participants of note	China (CDB, China Eximbank, Sinosure), Russia, India, Brazil, Saudi Arabia (which has growing ECA activity through Saudi EXIM), UAE — none of whose state-finance is bound by Arrangement terms
Current version	Updated periodically; current consolidated text and Sector Understandings published on OECD website with periodic revision-date stamps
Notification regime	Participants must notify each other (and the OECD Secretariat) of transactions falling within scope; transactions deviating from common terms require notification and (in some cases) common-line derogation

1.1 What the Arrangement disciplines (and does not)

The Arrangement applies to:

Long-tenor (≥ 2 years) officially supported export credits — buyer credit, supplier credit, sovereign loans tied to export-credit equivalents.
Direct lending by ECAs and insurance / guarantee cover on commercial bank lending.
Tied lending to foreign borrowers for purchase of participant-country goods or services.
Untied lending where the official support has export-credit-equivalent character.

The Arrangement does NOT apply to:

Short-term (< 2 year) trade finance (covered separately under the Berne Union short-term cooperation framework).
ODA (Official Development Assistance) loans meeting DAC concessionality criteria — JICA-implemented ODA loans are outside Arrangement scope.
Equity investment — JOGMEC’s equity participation in upstream resource projects is structurally outside scope.
Purely commercial bank lending without official support.
Domestic policy lending — JFC’s SME finance, DBJ’s domestic structured finance, JHF’s Flat 35 securitisation support are entirely outside.
Non-participant country state-finance — Chinese policy bank financing, Sinosure cover, Russian VEB / Eximbank, Indian Exim Bank, etc. are not bound.

The boundary between Arrangement-bound and Arrangement-free is the most important practical distinction. A single complex cross-border project may have JBIC OIL (Arrangement-bound) alongside JOGMEC equity (outside) alongside JICA ODA loan (outside) alongside NEXI cover (Arrangement-bound) alongside megabank commercial debt (outside in pure-commercial-bank form, but Arrangement-bound where the megabank tranche carries NEXI cover bringing it back into the Arrangement perimeter via the official-support classification).

2. Core disciplines

2.1 Maximum repayment tenor

Tenor is constrained by country category and sector:

Country category	General maximum tenor (under the general rules)
Category I (high-income OECD)	Up to 5 years (extendable in specific cases under common-line)
Category II (all other countries)	Up to 10 years

Sector understandings extend tenor for specific sectors significantly:

Sector understanding	Maximum tenor under sector rules
Ship Sector Understanding (SSU)	Up to 12 years from delivery for vessels
Aircraft Sector Understanding (ASU)	Up to 12 years for large civil aircraft
Nuclear Power Sector Understanding (NSU)	Up to 18 years for nuclear power plant exports
Climate Change Sector Understanding (CCSU)	Up to 22 years for renewable energy / hydrogen / ammonia / CCS / certain rail metro / climate-friendly water and storage
Coal-Fired Electricity Generation Sector Understanding (CFSU)	Tightened 2021 — effectively prohibits new unabated coal-fired power-export finance among participants
Railway Infrastructure	Up to 14 years for projects meeting climate-friendly criteria

2.2 Minimum Premium Rate (MPR) — keyed to Country Risk Classification (CRC)

The OECD maintains a single Country Risk Classification (CRC) scale from 0 to 7, where 0 indicates lowest risk (typically high-income OECD countries) and 7 indicates highest risk (heavily-indebted countries with imminent default risk). The CRC is reviewed periodically (typically several times per year) by the Participants’ country-risk experts group based on a quantitative model and qualitative review.

CRC	Approximate country examples (illustrative; subject to current OECD review)
0	High-income OECD (Japan, US, UK, Germany, France, Canada, Korea, Australia, Singapore, etc.)
1	Lower-risk emerging markets (Taiwan, Czech, UAE, Saudi Arabia, etc. at various points)
2	Various emerging markets (Indonesia, India, Malaysia, Mexico, Brazil, etc. at various points)
3-4	Mid-tier emerging markets (Philippines, Egypt, Türkiye, Vietnam, etc. at various points)
5	Higher-risk emerging markets
6	High-risk countries with significant debt-sustainability concerns
7	Highest-risk countries with imminent / actual default risk

The MPR is calculated as a function of CRC, tenor, transaction structure (sovereign vs sovereign-adjacent vs corporate), and credit risk mitigation (collateral, third-party guarantees). The MPR is a floor — ECAs may price above MPR but not below. The MPR-MTRO (Most Restrictive Other Terms) discipline ensures terms-package cannot be loosened through other levers to compensate for MPR.

2.3 Minimum interest rates — Commercial Interest Reference Rate (CIRR)

For official fixed-rate lending (as distinct from market-rate lending such as JBIC’s typical OIL pricing), participants must charge at least the Commercial Interest Reference Rate (CIRR) for the relevant currency and tenor. CIRRs are updated monthly by the OECD Secretariat based on government-bond yields plus a margin. The CIRR system ensures that fixed-rate official lending cannot be priced below market.

2.4 Good-governance disciplines

Anti-bribery: explicit obligation to take measures against bribery in officially supported export credit transactions.
Environmental and social due diligence: OECD Recommendation on Common Approaches for Officially Supported Export Credits and Environmental and Social Due Diligence (the “Common Approaches”) — sets common review standards for projects with potential adverse environmental / social impact.
Debt sustainability for low-income countries: Principles and Guidelines to Promote Sustainable Lending Practices in the Provision of Official Export Credits to Low-Income Countries — specific disciplines on lending to IMF/IDA-eligible low-income countries.

3. Sector Understandings detail

3.1 Ship Sector Understanding (SSU)

Disciplines export credits for vessel exports. Maximum 12-year tenor from delivery, minimum 20% down payment, sector-specific MPR. Adjusts general Arrangement rules to fit shipbuilding industry economics. Relevant for Japanese shipbuilders (policy-finance INDEX) and the megabank ship-finance lending alongside JBIC / NEXI.

3.2 Aircraft Sector Understanding (ASU)

Disciplines export credits for large civil aircraft (Airbus, Boeing, Embraer, COMAC). Up to 12-year tenor. Highly elaborated risk-based pricing through the ASU MPR framework. The ASU is the most heavily-used sector understanding in dollar terms globally. Japan’s specific role in ASU is via JBIC / NEXI support for Japanese-owned airlines (ANA, JAL) ordering large aircraft from foreign manufacturers, and (selectively) for Japanese-supplied aerospace components.

3.3 Nuclear Power Sector Understanding (NSU)

Up to 18-year tenor for nuclear power plant exports. Reflects long construction / commissioning timeline of NPP projects. Relevant historically for Japanese nuclear exports (Toshiba-Westinghouse during the pre-2017 period before Westinghouse Chapter 11; Hitachi-GE during the pre-2020 period before Hitachi’s withdrawal from UK Wylfa and other projects); currently less actively used by Japanese ECAs due to Japan’s domestic post-Fukushima nuclear-export posture but remains in force.

3.4 Climate Change Sector Understanding (CCSU) — the structural climate-policy lever

Originally established in 2012 and substantially expanded in 2023, the CCSU is the most important Arrangement modification for the climate-transition era. Categories under CCSU eligible for up to 22-year tenor:

Renewable energy generation (solar, wind, geothermal, biomass, small-hydro, marine).
Hydrogen / ammonia production, storage, transport.
Carbon capture, utilisation, and storage (CCUS / CCS).
Energy efficiency projects above defined thresholds.
Climate-friendly water management and storage.
Selected rail / urban transit projects meeting climate-friendly criteria.
Selected battery storage and grid-modernisation projects.

The 2023 CCSU modernisation was the most significant Arrangement reform since the 2009 Tokyo Action Statement. It expanded both category coverage and maximum tenor (some categories now to 22 years), directly enabling NEXI / JBIC and peer ECAs to underwrite long-tenor renewables / hydrogen / ammonia financing that would not be feasible under general Arrangement tenor caps.

3.5 Coal-Fired Electricity Generation Sector Understanding (CFSU) — the 2021 climate-policy tightening

Originally established in 2015. Substantially tightened in 2021 such that new unabated coal-fired power export finance is effectively prohibited among Arrangement participants. This was a structural climate-policy outcome with significant downstream effects on JBIC / NEXI underwriting:

Pre-2021: Japanese ECA support for coal-fired thermal power plants in Indonesia, Vietnam, Bangladesh, India, and elsewhere was a continuing (and politically contested) policy direction.
2021 CFSU tightening: effectively closed the Arrangement-compliant channel for new unabated coal-fired plant export finance.
Post-2021: Japanese ECA coal-finance pipeline closed for unabated plants; selectively continuing for projects with abatement (CCS) integration; significant institutional impact on JBIC OIL pipeline composition and on the Japanese policy-statement on “no new overseas coal”.

4. Country-Risk Classification (CRC) mechanism

The CRC system is the operational heart of the MPR discipline. CRC is:

Reviewed periodically (typically several times per year) by the Participants’ country-risk experts group.
Based on a quantitative model assessing macroeconomic / fiscal / external balance / debt-sustainability metrics plus political-risk overlay.
Reviewed against bilateral and multilateral analysis (IMF Article IV, World Bank Country Risk, Standard & Poor’s / Moody’s / Fitch sovereign rating, OECD Economic Outlook).
Published on the OECD website as a public reference list — CRC 0-7 for each country with regular updates.
Operationalised by each participant ECA — NEXI / JBIC / US EXIM / K-EXIM / UKEF use the CRC directly to calculate MPR for transactions in each country.

The CRC has analytic uses beyond Arrangement compliance: it is one of the few public sovereign-risk classifications with consistent methodology across countries, and is used by some commercial banks and rating agencies as a cross-reference for sovereign-risk benchmarking.

6. Climate transition update (2023-2025)

The 2023-2025 period has been the most active Arrangement-reform period in over a decade:

2023-04 CCSU modernisation: structurally important — enables long-tenor (up to 22-year) ECA support for renewables / hydrogen / ammonia / CCS / climate-friendly water and rail metro. Directly affects JBIC OIL and NEXI cover for Japanese renewable / hydrogen / ammonia projects in ASEAN, Middle East, Australia, Latin America.
2021 CFSU tightening (with ongoing implementation effects through 2025): continues to constrain new unabated coal pipelines; Japan’s policy-statement on “no new overseas coal” aligned with the Arrangement direction.
Critical Minerals Sector Understanding (under discussion): not yet adopted as of mid-2026; debate on whether to extend tenor or modify MPR for critical-minerals projects (lithium, cobalt, nickel, rare earths) to compete with non-Arrangement state finance.
Climate-aligned MPR debate: discussion of whether MPR should be modified to reflect climate-transition project risk profiles (some renewables / hydrogen / CCS projects carry technology / market-development risk that may not be well-captured by sovereign CRC alone).

7. China and non-Arrangement state finance — the central asymmetry

The Arrangement does not include China. Chinese state finance (CDB / China Eximbank for lending; Sinosure for insurance) operates outside Arrangement disciplines. The practical implications:

Longer tenors: Chinese state finance can offer tenor structures unconstrained by Arrangement caps, e.g. 20-30 year project finance in markets where Arrangement participants are capped at 10-12 years (outside CCSU eligibility).
Lower pricing: Chinese state finance can price below Arrangement MPR floors.
Different conditionality: Chinese state finance does not adhere to Common Approaches environmental / social due diligence in the same form (though China has its own equator-principles-adjacent frameworks).
Different governance: Chinese state finance does not have notification / peer-review disciplines.

This creates asymmetric competition in markets where Japanese ECAs and Chinese state finance compete for similar projects — notably ASEAN infrastructure, African resource and infrastructure, Latin American resource projects, and (post-2022) friend-shoring / supply-chain competition. The OECD-side response has included calls for non-OECD state finance to join Arrangement disciplines, multilateral coordination through G7 / G20 frameworks, and selective Arrangement modernisation (CCSU expansion, possible Critical Minerals Sector Understanding) to make Arrangement-compliant terms more competitive on strategically important projects.

9. Counterpoints

Incomplete map of state finance. The Arrangement is not a complete map of all state finance. It excludes many non-Arrangement products, equity investment, ODA, and non-participant support. The “Arrangement perimeter” question is the first analytic question before assessing competitive dynamics.
Gentleman’s Agreement enforceability. The Arrangement is non-binding in legal terms. Enforcement is through notification, common-line-derogation review, and political peer pressure. Participants can in principle derogate from common terms by notifying and absorbing the political cost.
Short-tenor exclusion. The Arrangement covers ≥ 2-year repayment. Short-term trade finance falls outside (covered separately under Berne Union short-term cooperation). The dividing line at 2 years has been criticized as somewhat arbitrary in the era of long-tenor trade finance and short-tenor project finance.
Climate-policy lever or barrier. The CCSU expansion is structurally important for climate-transition finance, but the CFSU coal-tightening has been criticized in some emerging-market contexts where coal-fired power remains part of the realistic energy mix. The counterargument is that the Arrangement participants’ collective decision to tighten coal-fired export finance is consistent with Paris Agreement temperature-aligned pathways.
China-asymmetry critique. The central structural critique of the Arrangement in the 2020s is that it disciplines OECD participants while Chinese state finance operates outside the same disciplines, producing competitive asymmetry in strategic-finance contexts. The counterargument is that Arrangement disciplines protect the long-run sustainability of official export-credit by preventing race-to-the-bottom subsidization, even if competition with non-participant state finance is uneven.
Privatisation debate (institutional context). The Arrangement is not an institution to be privatised — it is a rule-book. But its disciplines are central to whether ECAs (NEXI, US EXIM, K-EXIM, UKEF, etc.) operate as quasi-commercial entities or as policy-subsidy vehicles. The Arrangement’s MPR / CIRR / tenor disciplines push ECAs toward cost-recovery / commercial-grade pricing rather than open subsidy.
BIS Basel III interaction. The Arrangement does not regulate Basel-III treatment of ECA-insured / ECA-guaranteed exposures, but the Basel framework’s treatment of these exposures (notably credit risk mitigation / CRM treatment for unfunded ECA guarantees, and risk-weighted asset calculations for ECA-insured loans) is the mechanism by which megabank appetite for cross-border project-finance lending materially depends on ECA cover. The Basel framework treats ECA-guarantees / insurance as substituting the borrower’s risk-weight for the ECA’s (typically much lower) risk-weight, which is the structural reason Arrangement-compliant ECA cover is in high demand from megabank lenders.
Mandate creep critique (Sector Understanding proliferation). The growth from no Sector Understandings (pre-1980s) to five active (SSU / ASU / NSU / CCSU / CFSU) plus debate on a sixth (Critical Minerals) has been called “Sector Understanding proliferation”. The counterargument is that sector-specific economics genuinely require sector-specific tenor / pricing rules.

10. Open questions

Which Japanese overseas projects use Arrangement-compliant JBIC / NEXI support versus the JOGMEC-equity / JICA-ODA lanes that sit outside.
How CCSU 2023 modernisation actually changes Japan’s official-finance composition over 2025-2030 — does the long-tenor renewable / hydrogen / ammonia / CCS pipeline materially expand?
Whether the Critical Minerals Sector Understanding moves forward and what its tenor / pricing structure would be.
Whether non-OECD state finance (particularly China) ever moves toward Arrangement-equivalent disciplines through G7 / G20 / multilateral frameworks.
How sovereign-stress cases (Sri Lanka, Pakistan, Lebanon, Egypt, Argentina, Ghana, Zambia, others) flow through CRC adjustments and what this does to MPR for ECA cover.
Post-Russia-sanctions enforcement infrastructure — how Arrangement participants coordinate sanctions overlay with Arrangement compliance going forward.
Whether Arrangement modernisation extends to recognise new transaction types (e.g. minerals offtake-backed structured trade finance, hydrogen / ammonia long-term supply agreements with embedded ECA cover).
How CRC accuracy holds up against actual default / restructuring outcomes — back-testing of CRC vs eventual sovereign credit events.
