You hold ₦100M of user wallet liabilities. On any given day, you'd be surprised by maybe ₦5M of withdrawals, most users leave their money parked. Holding ALL ₦100M in a 0% checking account at your sponsor bank is leaving money on the table. Holding ALL ₦100M in 6-month treasury bills is reckless, first hint of a withdrawal storm and you can't liquidate fast enough. The treasury answer is LADDERING: a tiered structure of overnight, 30-day, and 90-day buckets where each bucket's size is calibrated to expected withdrawal demand at that horizon. This lesson posts the initial laddering of ₦100M and shows the YIELD that laddering captures.
