Why this matters for prefunding

When Thailand banks or payment rails close, a top-up sent to a local payout partner may not land until the next business day. Remittance demand often rises around the same holidays. Fund the corridor before the closure, sized for the closed days plus your normal top-up lead time. Check your corridor runway.
