Overview
This series examines Colombia’s CUD from RTGS balance constraints to reserve-policy evidence, participant incentives, network timing, and monitoring. Lower requirements were associated with earlier lower-percentile settlement but later high-value tails in 2018–2025; pandemic measures and the 2024 DCV transition limit causal certainty.
Learning outcomes
- In Colombia’s CUD, lower required reserves were associated with earlier lower-percentile settlement but later high-value tails.
- The pattern reflects a redistribution of payment value, not a uniform delay or acceleration.
- Timing depends on usable intraday liquidity, repo funding, incoming flows, participant position, and infrastructure.
- The evidence guides monitoring of late-day concentration but does not prove a universal causal rule or reserve threshold.

PlansFAQ
Why can lower reserve requirements delay large payments in Colombia’s CUD?
Lower requirements can make liquidity available for competing uses, so institutions may settle smaller obligations early and defer large payments tied to funding or incoming flows.
Did Colombia’s reserve cuts make all CUD payments slower?
No. The CUD study found a redistribution: lower percentiles moved earlier while upper value percentiles moved later, especially after 2024.
What should be monitored after a liquidity-policy change?
Monitor cumulative value percentiles, the share unsettled at 17:00, repo reliance, rate spreads, incoming-payment dependence, concentration, and infrastructure effects.
How certain is the evidence from Colombia’s CUD?
It supports an association over 2018–2025 and a plausible mechanism, but pandemic measures and the 2024 DCV transition prevent attributing every timing change to reserves alone.
