COE Categories, Tenure and Quota Anchors

Premiums move every bidding exercise. Quote a premium only with its exercise date; structural rules below change more slowly. Narrative interpretation lives in coe system.

Population bases

Category A/B/C/D/E COE bidding category for the vehicle type and power band stated ERP charges; driving-licence class
Quota Premium (QP) Lowest successful bid in a closed exercise — not a forecast or long-run average Prevailing Quota Premium for renewals
Total COE quota Three-month supply across all categories for one bidding quarter Single-category quota in one exercise
Vehicle population growth Annual allowance added to the quota formula by category Total cars on the road; ERP revenue
