COE Supply After the 2020 Suspension: What Can Be Established
Separate the April–June 2020 bidding suspension from deregistrations, quota allocations and later price movements.
COE bidding was suspended in April–June 2020 and resumed in July. That interruption is part of the history of later supply and prices, but it does not by itself prove that a renewal spiral caused the subsequent highs.
Four records answer four different questions
- The exercise calendar shows when bidding occurred.
- Quota announcements show the certificates allocated under the policy then in force.
- Deregistration and revalidation statistics show vehicles leaving the register or renewing entitlement.
- Results show premiums, quota and bids in the exercises held.
Substituting one series for another creates errors. An absent auction is not a zero premium, a quota is not a registration count, and the number of renewals divided by new registrations is not automatically an owners’ renewal rate.
Use the rules from the period being explained
A later quota formula cannot simply be projected backwards to explain a 2020 announcement. Likewise, the suspension does not establish that all unoffered certificates permanently disappeared. Read the allocation and redistribution announcements for the relevant window.

What a renewal-feedback claim would require
Owners can choose between renewal and replacement, so there is a plausible connection between these choices and later deregistrations. Demonstrating its size requires a defined population of vehicles eligible to renew, their observed choices and the subsequent allocation calculation. Premium increases alone do not provide those inputs.
There is also no fixed direction from PQP to new-car demand. A high renewal bill can encourage an owner to replace the vehicle, stop owning one or renew despite the expense. A model needs to state those responses rather than assume every owner behaves alike.
How to assess later interventions
LTA announced additional injections in October 2024, starting progressively in February 2025. Compare each later allocation with its published components. Do not attribute the entire change to injections if replacement counts and other adjustments changed too.
For today’s buyer, the relevant inputs are the current allocation, the applicable PQP if renewing, and the complete replacement quotation. Historical shocks can help identify risk, but cannot establish that the next disruption must last four years or produce the same price path.
Use Quota Watch and the PQP page together. Keep a separate reserve for repairs and alternative transport when comparing an older car with a new purchase.
