Licensed moneylenders are capped at 4 percent monthly interest under the Moneylenders Act, and credit card issuers face MAS conduct rules and a 12-times-monthly-income aggregate underwriting limit. BNPL faces neither. I compute the effective monthly rate implied by the late fee schedules of the three accredited Singapore BNPL providers (Atome, Grab PayLater, SeaMoney SPayLater) across seventeen ticket-size scenarios and benchmark these against the Moneylenders Act ceiling. On per-incident absolute fees, BNPL charges fall below the moneylender maximum. On effective rates the picture inverts: BNPL produces monthly rates of 1 to 75 percent on the deferred amount. The same S$15 Atome late fee implies a 75 percent rate on a S$20 missed instalment, 15 percent on S$100, and 4.5 percent on S$333. The statutory rate cap binds uniformly on rate; the BNPL flat fee binds uniformly on dollar amount. I calibrate the analysis to MAS data and to the CFPB 2025 BNPL studies, which show high loan stacking and concentration in subprime borrowers. The structural patterns hold across jurisdictions. BNPL escapes the rate-cap regime through legal classification (deferred payment, not loan) rather than through superior consumer protection. I propose extending Moneylenders Act discipline through a two-component fee structure (capped flat administrative fee plus percentage rate cap) and mandating full Credit Bureau Singapore reporting of BNPL exposure, building on rather than replacing the current industry Code of Conduct.\n                  <bold>JEL Codes:<\/bold>\n                  G18, G28, G51, K23, D18.\n                <\/p>","DOI":"10.21203\/rs.3.rs-9581198\/v1","type":"posted-content","created":{"date-parts":[[2026,5,16]],"date-time":"2026-05-16T14:26:13Z","timestamp":1778941573000},"source":"Crossref","is-referenced-by-count":0,"title":["The Inverted Regulatory Perimeter in Singapore Buy-Now-Pay-Later"],"prefix":"10.21203","author":[{"given":"Boon Chuan","family":"Lim","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","container-title":[],"original-title":[],"link":[{"URL":"https:\/\/www.researchsquare.com\/article\/rs-9581198\/v1","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.researchsquare.com\/article\/rs-9581198\/v1.html","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,16]],"date-time":"2026-05-16T14:26:13Z","timestamp":1778941573000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.researchsquare.com\/article\/rs-9581198\/v1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,5,16]]},"references-count":0,"URL":"https:\/\/doi.org\/10.21203\/rs.3.rs-9581198\/v1","relation":{},"subject":[],"published":{"date-parts":[[2026,5,16]]},"subtype":"preprint"}}
