Monitoring systems generate hundreds to thousands of alerts a day, and unusual alerts should not automatically be treated as suspicious. The Guidelines aim to improve the quality of the STRs filed, reduce false positives and defensive filings, and make institutions show how they reached a view.<\/p>\n  <p>For a risk leader the useful reading is a decision chain: what each alert must show, how long the institution has, and what record survives when an alert is not filed.<\/p>\n\n  <!-- TOP VISUAL -->\n  <div class=\"nx-media\">\n    <img decoding=\"async\"\n      src=\"data:image\/svg+xml,%3Csvg xmlns='http:\/\/www.w3.org\/2000\/svg' width='820' height='460' viewBox='0 0 820 460'%3E%3Cdefs%3E%3ClinearGradient id='bg' x1='0' y1='0' x2='1' y2='1'%3E%3Cstop offset='0' stop-color='%2300184C'\/%3E%3Cstop offset='1' stop-color='%23073EA1'\/%3E%3C\/linearGradient%3E%3C\/defs%3E%3Crect width='820' height='460' rx='22' fill='url(%23bg)'\/%3E%3Ctext x='410' y='70' text-anchor='middle' font-family='Arial, sans-serif' font-size='30' font-weight='700' fill='%23ffffff'%3EFrom alert to decision%3C\/text%3E%3Crect x='86' y='132' width='165' height='92' rx='18' fill='%23ffffff' opacity='0.92'\/%3E%3Crect x='328' y='132' width='165' height='92' rx='18' fill='%23ffffff' opacity='0.88'\/%3E%3Crect x='570' y='132' width='165' height='92' rx='18' fill='%23ffffff' opacity='0.84'\/%3E%3Crect x='207' y='272' width='165' height='92' rx='18' fill='%23ffffff' opacity='0.86'\/%3E%3Crect x='449' y='272' width='165' height='92' rx='18' fill='%23ffffff' opacity='0.90'\/%3E%3Ccircle cx='168' cy='162' r='16' fill='%23073EA1'\/%3E%3Ccircle cx='410' cy='162' r='16' fill='%23073EA1'\/%3E%3Ccircle cx='652' cy='162' r='16' fill='%23073EA1'\/%3E%3Ccircle cx='290' cy='302' r='16' fill='%23073EA1'\/%3E%3Ccircle cx='531' cy='302' r='16' fill='%23073EA1'\/%3E%3Ctext x='168' y='198' text-anchor='middle' font-family='Arial, sans-serif' font-size='17' font-weight='700' fill='%2300184C'%3EAlert%3C\/text%3E%3Ctext x='410' y='198' text-anchor='middle' font-family='Arial, sans-serif' font-size='17' font-weight='700' fill='%2300184C'%3EReview%3C\/text%3E%3Ctext x='652' y='198' text-anchor='middle' font-family='Arial, sans-serif' font-size='17' font-weight='700' fill='%2300184C'%3ESuspicion%3C\/text%3E%3Ctext x='290' y='338' text-anchor='middle' font-family='Arial, sans-serif' font-size='17' font-weight='700' fill='%2300184C'%3ESTR%3C\/text%3E%3Ctext x='531' y='338' text-anchor='middle' font-family='Arial, sans-serif' font-size='17' font-weight='700' fill='%2300184C'%3ERecord%3C\/text%3E%3Ctext x='410' y='410' text-anchor='middle' font-family='Arial, sans-serif' font-size='20' font-weight='600' fill='%23AEC9FF'%3EA documented chain%3C\/text%3E%3C\/svg%3E\"\n      alt=\"NFIU STR Guidelines visual showing the decision chain from monitoring alert through review and a determination of suspicion to an STR within 24 hours or a written record of why none was filed\"\n      loading=\"lazy\"\n      width=\"820\"\n      height=\"460\"\n    >\n    <p class=\"nx-caption\">Each alert needs a documented route to an STR within 24 hours of suspicion, or a written reason why none was filed.<\/p>\n  <\/div>\n\n  <!-- QUICK ANSWER -->\n  <div class=\"nx-callout\">\n    <div class=\"nx-callout-title\">Quick answer<\/div>\n    <p>The Nigerian Financial Intelligence Unit\u2019s Guidelines for the Identification, Verification and Reporting of Suspicious Transactions, issued on 13 December 2024, require a financial institution to screen and review alerts, assess the facts and context, link red flags and explain its grounds for suspicion before filing. An STR is due to the NFIU within 24 hours of the transaction being deemed suspicious, scrutiny should not exceed 72 hours, and alerts investigated but not filed must be recorded internally with written reasons.<\/p>\n  <\/div>\n\n  <h2 id=\"what-an-alert-must-show-before-an-str\"><span class=\"ez-toc-section\" id=\"What_an_alert_must_show_before_an_STR\"><\/span>What an alert must show before an STR<span class=\"ez-toc-section-end\"><\/span><\/h2>\n  <p>According to Moroom Africa Legal Consults\u2019 summary of the Guidelines, before filing an STR an institution must establish reasonable grounds to suspect a link to an ML, TF or PF offence. It does this by screening and reviewing all transaction alerts, assessing the facts and context, linking ML\/TF\/PF indicators or red flags to that assessment and explaining how the facts, context and indicators led to a reasonable ground for suspicion. It must also take account of high-risk predicate offences in the National Risk Assessment and relevant sectoral assessments, and of higher-risk jurisdictions.<\/p>\n  <p>The facts to assess include the transaction\u2019s date, time, location, amount or type and any other available information, which can come from account opening or due diligence updates.<\/p>\n  <div class=\"nx-stack\">\n    <div class=\"nx-stack-layer\">\n      <div class=\"nx-stack-icon\">01<\/div>\n      <div>\n        <h4>Screen and review the alert<\/h4>\n        <p>All transaction alerts are screened and reviewed.<\/p>\n      <\/div>\n    <\/div>\n    <div class=\"nx-stack-layer\">\n      <div class=\"nx-stack-icon\">02<\/div>\n      <div>\n        <h4>Assess facts and context<\/h4>\n        <p>Date, time, location, amount, type and customer information.<\/p>\n      <\/div>\n    <\/div>\n    <div class=\"nx-stack-layer\">\n      <div class=\"nx-stack-icon\">03<\/div>\n      <div>\n        <h4>Link red flags<\/h4>\n        <p>ML\/TF\/PF indicators are tied to the assessment of the facts.<\/p>\n      <\/div>\n    <\/div>\n    <div class=\"nx-stack-layer\">\n      <div class=\"nx-stack-icon\">04<\/div>\n      <div>\n        <h4>Explain the grounds<\/h4>\n        <p>How facts, context and indicators produced reasonable suspicion.<\/p>\n      <\/div>\n    <\/div>\n  <\/div>\n\n  <h2 id=\"what-a-fileable-str-contains\"><span class=\"ez-toc-section\" id=\"What_a_fileable_STR_contains\"><\/span>What a fileable STR contains<span class=\"ez-toc-section-end\"><\/span><\/h2>\n  <p>The Guidelines also set the content of an STR and the documents that go with it.

Nexiant brings these questions together across KYC, fraud and monitoring as a design discipline, not as a claim about one integrated system.<\/p>\n\n\n  <hr class=\"nx-divider\">\n\n  <h2 id=\"frequently-asked-questions\"><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span>Frequently Asked Questions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n  <!-- FAQ -->\n  <div class=\"nx-faq\">\n    <div class=\"nx-faq-item\">\n      <button class=\"nx-faq-q\" aria-expanded=\"false\">What are the NFIU STR Guidelines?<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\">They are the NFIU\u2019s Guidelines for the Identification, Verification and Reporting of Suspicious Transactions Related to ML, TF and PF for Financial Institutions, issued on 13 December 2024 under section 28(2) of the NFIU Act 2018.
