Why is international regulatory coordination so difficult?

The short answer

International regulatory coordination is the process by which national regulators align their rules and supervisory practices to address financial risks that cross borders. Without coordination, financial firms can arbitrage across jurisdictions, undermining the effectiveness of any individual regulator’s framework.

The structural difficulty of coordination was articulated by economist Dani Rodrik in 2007: deep economic integration, national sovereignty, and democratic legitimacy form a trilemma — only two can be fully achieved simultaneously. Applied to financial regulation, this means that genuinely global financial integration requires either supranational regulatory authority (sacrificing national sovereignty) or harmonized national rules (constraining domestic democratic flexibility).

The non-trivial observation is that the post-2008 architecture has consistently chosen the third option: managed integration with discretionary national variation. This produces incomplete coordination by design, not by accident.

What the data shows

The empirical record of international coordination shows striking variation across topics.

Key dimensions (FSB peer reviews, IMF Article IV reports, BIS surveys 2010-2026):

• Basel III implementation: above 80% peer review compliance across G20 jurisdictions by 2024
• OTC derivatives clearing: more than 80% of standardized IRS notional cleared globally by 2024
• Shadow banking standards: below 60% peer review compliance across surveyed jurisdictions
• Crypto-asset regulation: high implementation divergence (EU MiCA 2023-2024, U.S. fragmentary, China prohibitive, Japan licensing)
• Capital flow management: IMF endorsement of macroprudential capital flow measures (2012, updated 2022) but persistent national divergence in practice
• Cross-border banking supervision: the Basel “Concordat” framework (1975, updated 2003) governs home-host coordination, but practical effectiveness has been documented as variable

The 2018-2025 period has been marked by additional fragmentation pressures: the U.S.-China strategic competition, post-Brexit UK divergence, EU strategic autonomy initiatives, and the rise of digital and crypto assets that escape the traditional regulatory perimeter entirely.

Why it happens — the macro mechanism

The difficulty of coordination operates through three principal channels.

Channel 1 — The political trilemma. Rodrik’s framework, originally developed for trade policy, applies forcefully to financial regulation. National political constituencies value distinct policy outcomes (consumer protection, financial inclusion, market efficiency, financial stability) with different weights. International coordination requires accepting trade-offs that may be politically costly domestically. The framework is described in Financial Stability Board.

Channel 2 — Regulatory arbitrage as a market response. Financial firms respond to regulatory differences by shifting activities to less-regulated jurisdictions. This dynamic creates pressure on regulators in stricter jurisdictions to relax rules to retain activity, and on regulators in more permissive jurisdictions to tighten only at the margin. The non-trivial observation, contrary to the standard reading that arbitrage is a coordination problem to solve, is that some level of regulatory diversity is also a feature: it allows experimentation, comparative assessment, and locally-calibrated rules — see Securities regulation globally.

The third channel concerns geopolitical fracture lines.

Channel 3 — Geopolitical fragmentation. The post-2018 era has seen increasing strategic divergence between the U.S., EU, and China on technology regulation, cross-border data flows, payment system architecture, and central bank digital currency development. These divergences spill into financial regulatory coordination through cross-border data restrictions (which complicate AML/KYC), sanctions compliance (which fragments correspondent banking), and CBDC interoperability questions — see Strong dollar structural regime.

Synthesis by regime: in the 1990-2008 period, coordination was framed by the “Washington Consensus” liberalization paradigm and led to broadly aligned rules but inadequate macroprudential frameworks. From 2009 to 2018, the post-GFC reform wave produced strong coordination on banking, payments, and OTC derivatives clearing, with FSB peer review compliance running above 80% on Basel III. From 2018 onward, geopolitical fragmentation, technological disruption, and political backlash against globalization have stressed the coordination architecture; new topics like crypto-assets, stablecoins, and CBDC interoperability have shown markedly less convergence than post-GFC banking reforms.

Coordination on banking succeeded because everyone had just been frightened at the same time; coordination on the next crisis depends on whether the next fright is also synchronized.

What it means for different economic actors

Internationally active firms. Cross-border financial firms face increasing compliance complexity as topic-by-topic coordination produces a patchwork of overlapping requirements. Compliance costs have risen substantially since 2018, particularly on AML, sanctions, and ESG disclosure.

National regulators. Regulators face the structural tension between FSB peer review pressure (favoring international consistency) and domestic political demands for tailored rules. The 2019 FSOC revisions and the 2023 U.S. Basel III Endgame proposal both illustrate domestic divergence pressures even within strong international frameworks.

Emerging market jurisdictions. Standard-takers rather than standard-setters historically face the highest costs of fragmentation, having to comply with rules designed for advanced economies’ financial structures. The 2024-2025 push for greater EM voice within FSB and BCBS is a partial response to this asymmetry.

A common error is to view coordination failures as solvable through better technical design. The structural sources are political: divergent national interests, geopolitical fragmentation, and democratic accountability constraints. Better technical work matters but cannot overcome these constraints.

Frequently asked questions

What is Rodrik’s political trilemma and how does it apply to finance?

Dani Rodrik (Foreign Affairs, 2007) argued that deep economic integration, the nation-state, and democratic politics cannot fully coexist. Applied to financial regulation, this means that fully integrated global finance requires either supranational regulators (limiting national sovereignty) or harmonized national rules (limiting domestic democratic discretion). Most actual frameworks choose partial integration with national variation, producing systematic but incomplete coordination. The empirical record of post-GFC reforms is broadly consistent with this prediction.

Why has crypto-asset coordination lagged behind banking coordination?

Three factors combine. First, crypto emerged outside the existing regulatory perimeter, requiring new frameworks rather than adaptation of existing ones. Second, member jurisdictions have different policy positions: the EU adopted MiCA in 2023-2024, the U.S. has pursued enforcement-led regulation, China prohibits most crypto activity, while Japan and Switzerland have pursued licensing approaches. Third, cross-border crypto activity is technologically more diffuse than traditional banking, complicating practical supervision. The FSB has produced high-level coordination principles, but national implementation has diverged materially.

How does the U.S. dollar’s role complicate international coordination?

The dollar’s reserve currency role gives U.S. regulators outsized influence over international financial activity, even outside U.S. jurisdiction. Sanctions compliance, correspondent banking access, and FX swap line architecture all flow through dollar-centric infrastructure. This creates asymmetric coordination dynamics: U.S. regulatory choices produce extraterritorial effects, while other jurisdictions face more bounded international leverage. The post-2018 push for euro internationalization, RMB internationalization, and CBDC development is partly a response to this asymmetry.
