The solution
Singapore has to keep a car population small on an island with no room to expand its roads, so rather than let congestion ration driving, the state caps the number of vehicles outright. Since 1990 the cap has been administered as the Certificate of Entitlement system: to register a new car a buyer must first win a COE in a public tender, and certificates are issued in categories that split the fleet by vehicle size and power.
The clearing prices are watched like a stock ticker because they are the market's running estimate of what mobility is worth. In the tender of September 9, 2026, Category A premiums, for cars of 1,600cc and below with no more than 130 horsepower and including most mainstream EVs, closed at a record S$133,009, up 3.5 percent and past the S$129,000 record set that July. Larger cars in Category B cleared at S$135,001, commercial vehicles at S$93,101, the open Category E at S$137,890, and motorcycles at S$12,556, a fifth consecutive rise.
The tender's cadence is part of the design: exercises run roughly every two weeks, and when one was pushed to a three-week gap that September, dealers noted the extra week simply gave the trade more time to accumulate orders, which fed straight into the next clearing price. The COE has become both the state's instrument for holding the fleet flat and a national barometer of car scarcity that every household understands.
What it achieved
Auction the right to register a car
Why it worked
Capping quantity and auctioning the right to the cap makes the scarcity price transparent, instead of hiding it in queues, waiting lists or dealer markups.
Category bands keep the auction politically legible, separating motorcycles, family cars, luxury cars and commercial vehicles so scarcity lands where demand is.
The regular tender cadence lets the market re-price scarcity continuously, so the fleet cap binds without sudden clampdowns.
Bidders pay the market-clearing number for exactly the entitlement they need, which is why a small-car certificate now costs more than the car itself.
What can be applied
When demand outstrips fixed supply, auction the entitlement instead of administering allocation. A clearing price kills queues, side payments and luck-based rationing at once.
Aftermath
COE premiums have become a fixture of Singaporean life and politics, with record premiums regularly making national news and shaping household budgets, dealer inventories and EV adoption incentives. The mechanism has run for more than three decades, survived every technology shift in the fleet, and remains the world's clearest example of a government auctioning access to ownership rather than building more roads.
