June 2026 &nbsp;\u00b7&nbsp; RegTech<\/span>\n  <p class=\"nx-meta\">Japan&#8217;s National AML\/CTF\/CPF Action Plan for FY2024-2026 identifies the development of shared compliance infrastructure among regional financial institutions as a specific priority initiative.<\/p>\n<\/div>\n<h2><span class=\"ez-toc-section\" id=\"What_Shared_Infrastructure_Means_in_Practice\"><\/span>What Shared Infrastructure Means in Practice<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A shared AML\/CTF infrastructure model involves multiple financial institutions deploying a common compliance platform. The governance structure of the model is critical to how the FSA views it:<\/p>\n<p>In a properly structured shared infrastructure arrangement:<\/p>\n<ul><li>Each institution retains full ownership of its compliance programme and all regulatory responsibilities. The shared platform is a technology resource, not a transfer of compliance accountability.<\/li><li>Each institution&#8217;s customer data is fully segregated within the platform \u2014 no data sharing between participating institutions, and no access by one institution to another&#8217;s compliance records.<\/li><li>Each institution configures its own compliance parameters \u2014 risk thresholds, alert calibration, CDD tier criteria \u2014 independently of other participants. The shared element is the underlying technology and data, not the compliance decisions.<\/li><li>The platform provider maintains the technical infrastructure, data feeds, and regulatory update cycle on behalf of all participants, eliminating the per-institution maintenance overhead.<\/li><\/ul>\n<p>This model is distinct from compliance outsourcing, where one institution manages compliance on behalf of others. In the shared infrastructure model, each institution manages its own compliance programme \u2014 the sharing is of technology costs and data resources, not of compliance function.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Technology_Requirements_for_Consortium_Deployment\"><\/span>Technology Requirements for Consortium Deployment<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The technical architecture required for shared infrastructure deployment is not available in all AML compliance platforms. Specifically, the platform must support:<\/p>\n<ul><li>Multi-tenancy with full data segregation: multiple independent institutions must be able to operate on a single platform instance with complete separation of their customer data, compliance records, and configuration settings. Technical failures in data segregation would create both APPI violations and AML\/CTF programme integrity failures.<\/li><li>Per-institution configuration: risk parameters, alert thresholds, CDD tier criteria, and STR workflow settings must be configurable independently for each institution, without affecting the settings of other participants.<\/li><li>Shared data feeds at consortium economics: all participants benefit from the same high-quality PEP, sanctions, and adverse media data, at the economics of a shared subscription rather than individual contracts.<\/li><li>Centralised update management: platform updates, regulatory data refreshes, and compliance rule changes are deployed once and applied across all participants simultaneously \u2014 eliminating the maintenance overhead of individual deployments.<\/li><\/ul>\n<h2><span class=\"ez-toc-section\" id=\"The_Commercial_Case_for_Regional_Banks\"><\/span>The Commercial Case for Regional Banks<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The commercial rationale for shared infrastructure is straightforward for mid-market regional institutions evaluating their compliance technology options:<\/p>\n<ul><li>Platform cost per institution is substantially lower in a consortium model. Enterprise AML platform licensing, implementation, and maintenance costs that are prohibitive for a single mid-market institution become manageable when distributed across a consortium.<\/li><li>Implementation risk is reduced. Shared deployment on an established platform with prior regional bank experience eliminates the integration complexity and technical risk of greenfield implementation \u2014 a specific concern for institutions with limited internal IT compliance capability.<\/li><li>Ongoing maintenance and regulatory update overhead is eliminated. Platform updates, data feed management, and Japan-specific regulatory change management are handled by the platform provider rather than by each institution&#8217;s IT team \u2014 freeing internal resource for higher-value compliance activities.<\/li><li>Data quality is pooled. The quality of PEP and sanctions screening data, in particular, is a function of the data provider relationships maintained by the platform provider. Shared infrastructure gives regional banks access to premium data sources at economics typically available only to larger institutions.<\/li><\/ul>\n\n<hr class=\"nx-divider\">\n<h2><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span>Frequently Asked Questions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div class=\"nx-faq\">\n<div class=\"nx-faq-item\">\n  <button class=\"nx-faq-q\" aria-expanded=\"false\">Has the Japanese government endorsed shared AML infrastructure for regional banks?<span class=\"nx-chevron\"><svg viewBox=\"0 0 10 6\" stroke-width=\"1.5\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M1 1l4 4 4-4\"\/><\/svg><\/span><\/button>\n  <div class=\"nx-faq-a\">Yes.
