What Is COE in Singapore and How Does COE Bidding Work?

If you've ever looked at a new car price in Singapore and wondered why a Toyota Corolla Altis costs over $150,000, the answer is the Certificate of Entitlement — the COE. Before you can register a car in Singapore, you need one of these certificates, and getting one means competing in a government-run auction against every other buyer in the country. As of early 2026, winning that auction costs over $106,000 for a mass-market car. That's before you pay for the car itself.

Here's what the COE system is, why it exists, how bidding works, and what it means for your decision to buy.

Why Singapore Has COE

Singapore introduced the COE system in 1990 to control vehicle population on one of the world's most land-constrained urban islands. The idea is straightforward: the government decides how many new vehicles can be registered each year, then issues exactly that many certificates through a competitive auction. If demand exceeds supply — which it almost always does — the price rises until only the most willing buyers remain.

The system replaced earlier, cruder restrictions and has been continuously refined since. The basic logic has stayed the same: scarcity is engineered by policy, and buyers pay market rates for the right to own a car, not just for the car itself.

COE Categories

There are five COE categories, each covering a different vehicle type:

Category A — Cars with engine displacement of 1,600cc or below and power output at or under 130bhp (97kW), or electric vehicles with motors producing 110kW or below. This is the mass-market category: Corolla Altis, Honda Civic, BYD Atto 3, and similar.

Category B — Cars above 1,600cc or above 130bhp, or EVs above 110kW. Sedans like the BMW 5 Series, SUVs like the Volvo XC60, high-performance EVs.

Category C — Goods vehicles and buses.

Category D — Motorcycles.

Category E — Open category, valid for any vehicle except motorcycles. Cat E COEs typically cost the most and are usually used by buyers who want Cat B entitlements when Cat B supply is tight.

In February 2026, something unusual happened: Cat A premiums (S$106,501) exceeded Cat B premiums (S$105,001) for the first time in recent memory. Mass-market cars are now more expensive to certificate than luxury cars — a direct consequence of sustained demand from middle-income buyers and the influx of EVs into the Cat A bracket.

How COE Quota Is Set

The LTA determines quota based on deregistrations. When a vehicle is scrapped or exported, its COE is not renewed and a new COE slot becomes available. The supply for each exercise is calculated from vehicle deregistrations over the preceding rolling four quarters, plus a 0.25% annual growth allowance for commercial vehicles (Cat C).

The LTA can also inject "cut-and-fill" quotas — essentially borrowing future supply to stabilise prices in the short term. This happened in late 2025 and early 2026, with minor quota adjustments in both directions. The supply picture changes every bidding exercise, which is why tracking quota announcements matters for timing a purchase.

How Open Bidding Works

COE exercises run twice a month. The first exercise of each month typically opens on the first Monday and closes the following Wednesday at 4:00 PM. The second exercise follows the same pattern from the third Monday.

The auction uses an open bidding format. Here's the mechanics:

1. You submit a reserve price — the maximum you're willing to pay.
2. The system tracks how many bidders are willing to pay the Current COE Price (CCP), which starts low and rises in S$1 increments.
3. As the CCP climbs, bidders whose reserve is below the current price drop out.
4. When the number of remaining bidders equals the available quota, the auction closes.
5. Everyone who wins pays the same Quota Premium (QP) — the price at which supply met demand. This equals the highest unsuccessful bid plus S$1.

The key implication: you don't pay your reserve price, you pay the clearing price. If you bid S$120,000 but the QP settles at S$106,000, you get the COE for S$106,000. If you bid S$105,000 and the QP settles at S$106,001, you get nothing.

This means there's no advantage to bidding aggressively over the clearing price — you won't pay more unless the market clears at your bid level. But under-bidding by even S$1 loses you the exercise entirely.

Why Prices Have Stayed Above $100,000

COE prices crossed S$100,000 in 2022 and have not dropped back below that threshold as of early 2026. Several structural factors explain this:

Fixed supply, inelastic demand. Singapore's land area does not expand, so quota growth is deliberately constrained. Simultaneously, incomes have risen, making car ownership more affordable even at higher prices for upper-middle-income households.

EV adoption driving Cat A pressure. The LTA raised the Cat A power threshold from 97kW to 110kW specifically to accommodate popular EVs like the BYD Atto 3 within the lower-cost category. This concentrated more buyers into Cat A rather than spreading demand across Cat A and Cat B, pushing Cat A prices higher.

Private hire vehicle demand. While leasing companies and PHV operators accounted for less than 10% of COE wins in early 2026 — down from peak levels — they remain a persistent source of demand that didn't exist a decade ago.

Post-pandemic catch-up. The 2020–2021 supply disruptions created pent-up replacement demand that drove a rapid escalation from ~S$40,000 in 2020 to over S$100,000 by 2022. Prices have since stabilised but not reversed.

Historical Context: Where COE Has Been

COE prices have been volatile since the system's inception. There have been periods below S$20,000 (mid-2000s to early 2010s), a spike above S$90,000 in 2012–2013, a correction to S$40,000–S$50,000 range in 2015–2019, and then the current prolonged elevation above S$100,000. The lesson from the history is that prices can fall sharply — but they can also stay elevated for years. Timing the market is genuinely difficult.

How to Bid for COE

Bidding is done through your car dealer when buying new, or through your bank or directly through the LTA's OneMotoring portal for COE renewals. For new car purchases, the dealer typically handles the bid submission on your behalf — you set your maximum bid price, and the dealer enters it into the bidding system before the exercise closes.

Key things to know before bidding:

• You can only bid in one category per exercise with each vehicle. Cross-category bidding isn't possible for the same car registration.
• Bid your true maximum. Since you pay the clearing price (not your bid), there's no benefit to anchoring below what you'd actually pay. Under-bidding by a small margin can cost you the exercise.
• Monitor the CCP. The LTA publishes real-time CCP updates during the exercise. You can track these on OneMotoring and set alerts. The CCP is a useful indicator of where the clearing price is likely to land, though it can move sharply in the final hours.
• Failed bids refund fully. If you don't win, your deposit is returned.

The Singapore COE Navigator includes a bidding strategy section with worked examples of how to read CCP movements and time your maximum bid relative to historical clearing prices for each category.

What COE Means for Your Total Purchase Cost

The COE premium is only one component of the total cost of buying a car in Singapore. On top of COE, buyers pay the Open Market Value (OMV) of the car, Additional Registration Fee (ARF) calculated as a percentage of OMV, and Vehicular Emissions Scheme (VES) surcharges or rebates depending on the car's emissions profile. For a typical mass-market car in early 2026, total on-the-road prices run S$140,000–S$180,000.

The COE premium is also the primary driver of depreciation. Because the certificate expires after 10 years and has essentially no residual value if not renewed, most of what you pay for a COE is pure cost rather than an asset. At current Cat A PQP rates of S$106,000–S$107,000, annual COE depreciation alone exceeds S$10,000 per year before factoring in the car's own value decline.

Understanding the system is the first step. The harder questions — whether to buy now or wait, whether to renew versus scrap, which category suits your actual needs — require running the numbers on your specific situation. That's what the Singapore COE Navigator is built to help you do.
