For many Singapore vehicle owners, COE renewal only becomes urgent when the expiry date is close.

That is understandable. Nobody wants to give up unused COE unnecessarily, and if you are planning to take a COE renewal loan, waiting another month may feel like a way to delay your instalment commitment.

But when COE prices are rising or staying high, waiting is not just a timing decision. It becomes a financial decision.

The key question is no longer simply: “Should I renew my COE now or later?”

A better question is: “Will the next PQP increase be more expensive than the unused COE balance I may forfeit by renewing early?”

Based on the latest May 2026 COE results, this is an important question for Category A, Category B and Category C vehicle owners whose COE is expiring soon.

Why PQP Matters When Renewing Your COE

When you renew your COE, you do not bid for a new COE. Instead, you pay the Prevailing Quota Premium, better known as PQP.

LTA states that PQP is the moving average of COE Quota Premiums from the last 3 months of bidding exercises. This means PQP changes monthly and reflects recent COE bidding results, not just one bidding round. LTA also states that each month’s PQP can be checked after the second bidding exercise of the previous month has ended.

This is why rising COE prices can affect you even if you are not buying a brand-new car.

If recent bidding results are higher than the current PQP, future PQP may move upward as those higher results are included in the moving average.

Latest May 2026 COE Snapshot: Current COE Prices Are Above May PQP

The May 2026 first open bidding exercise closed with higher COE premiums across the main renewal categories. LTA’s open bidding results show Category A at $124,790, Category B at $126,236, and Category C at $87,479.

For comparison, the current May 2026 PQP shown by Motorist is $112,324 for Cat A, $114,577 for Cat B, and $77,884 for Cat C.

This gap does not guarantee that PQP will rise sharply, but it does show why many owners should review their renewal timing carefully.

When the latest COE result is already higher than the current PQP, the risk of paying more in the next renewal month becomes more meaningful. 

What Happens If COE Prices Stay Around the Current Level?

Many owners wait because they hope COE prices will fall before their renewal month.

That may happen. COE prices can move in either direction depending on quota, demand, dealer activity and buyer sentiment.

However, there is another possibility: COE prices may simply stay around the latest level.

Under that flat-COE scenario, PQP can still rise because PQP is based on a moving average. As lower earlier results are gradually replaced by higher recent results, the renewal price can move upward even if the next few bidding exercises do not climb further.

Using the May 2026 first bidding result as the flat-price assumption, the projected PQP figures are as follows. These projections are estimates based on LTA’s 3-month moving-average approach and the source projection model.

In simple terms, if COE premiums remain near the latest May 2026 level, the projected increase from May to July could be:

For owners whose COE expires in June or July, this is where the renewal decision becomes more time-sensitive.

But What About the Unused COE You Give Up?

Renewing early is not free of trade-offs.

LTA states that if you renew your COE before it expires, the new COE period starts from the first day of the month after you renew, and you will forfeit any unused portion of your previous COE. If you renew in the month your COE expires, the new COE starts the day after your previous COE expires, and you will not forfeit any part of the previous COE.

So the correct comparison is not simply: “Will PQP increase?”

It is: “Will the projected PQP increase be larger than the estimated value of my unused COE?”

A practical way to estimate the unused monthly value is to divide the current PQP by 120 months for a 10-year COE equivalent.

This is not an official LTA rebate formula. It is a simple comparison method to help vehicle owners understand whether renewing early may still make financial sense after factoring in the COE period they may give up.

Scenario 1: Your COE Expires Around End June 2026

If your COE expires around the end of June and you renew in May, you may give up about one month of unused COE value.

But if the projected June PQP materialises, the increase in PQP may be much larger than that unused value.

For a June-expiring vehicle, renewing earlier may still be cheaper overall if the next PQP rises as projected.

Scenario 2: Your COE Expires Around End July 2026

If your COE expires around the end of July and you renew in May, you may give up around two months of unused COE value.

However, the projected July PQP increase could still be significantly higher than the unused balance.

This is why some owners choose to renew before their expiry month, even though they know they may forfeit part of the existing COE period.

The potential saving is not from avoiding the forfeiture. The potential saving comes from locking in a lower PQP before the next increase.

How COE Renewal Timing Affects Your Loan Amount

If you are paying the full PQP in cash, the impact is direct: a higher PQP means a higher upfront renewal cost.

If you are taking a COE renewal loan, the effect is still important because a higher PQP usually means a higher financed amount.

RenewCOE.sg’s loan calculator page is designed to help owners estimate monthly instalments for passenger and commercial vehicle COE renewal, and the site notes that COE renewal financing support may include indicative rates and repayment options. Actual rates, approval and terms depend on assessment and current package availability.

Using the sample assumptions from the source draft – 10-year COE renewal, 100% PQP financing, 7-year repayment, and a 2.78% flat p.a. illustrative rate – the estimated monthly instalment difference is meaningful.

This is why “waiting one more month” may not always be cheaper.

Yes, waiting may delay the start of your instalments. But if PQP rises before you renew, you may end up financing a larger amount and paying more every month after that.

Market Watch: Why COE Demand May Stay Firm

COE prices are affected by both supply and demand.

The upcoming Car Expo 2026 is one event that may keep buyer interest active in the short term. The official event site describes The Car Expo 2026 as taking place on 9 and 10 May 2026 at Singapore Expo Hall 4 and 5, with more than 40 brands. sgCarMart also reported that the 2026 event features 48 brands, event-exclusive deals and prizes.

This does not mean COE prices must rise.

However, major car events often encourage bookings through promotions, packages and limited-time offers. If new vehicle bookings remain strong, COE bidding demand may stay firm in the next exercises.

For owners hoping for a sharp PQP drop before renewal, that is a risk worth considering.

So, Should You Renew Your COE Now?

There is no single answer for every owner.

The right decision depends on your COE expiry date, vehicle category, cash flow, renewal loan eligibility and whether you are comfortable with the risk of a higher PQP later.

However, based on the current May 2026 data, Cat A, Cat B and Cat C owners with COE expiring soon should seriously review their options now.

Renewing earlier may be worth considering if:

• Your COE expires in June or July 2026.
• You are renewing a Cat A, Cat B or Cat C vehicle.
• The current PQP is still lower than the latest COE bidding result.
• You prefer to lock in a known renewal cost instead of waiting for the next PQP update.
• You are taking a COE renewal loan and want to avoid financing a higher PQP later.
• You want professional help with the renewal process, loan application and paperwork.

Waiting may still be suitable if your COE expiry is further away, if you expect COE prices to fall, or if preserving every remaining day of your current COE is more important to you than avoiding projected PQP increases.

But if your expiry date is close, the numbers suggest that waiting may come with a higher cost risk.
