T&S View: In BNPL consolidation, managing cancellations and early arrears may beat scale

  • With Grab's acquisition of Atome, regional BNPL is entering a phase of absorption into large platforms.
  • In the same week Singapore enforced a cooling-off period for moneylender loans, showing regulation extending into the post-contract stage.
  • We think the gap between lenders will be driven by precision in managing cancellations and early arrears rather than loan volume; integration results are not yet visible.
