Market clearing is the price at which the quantity buyers want equals the quantity sellers offer, so every order that qualifies can trade at that one price and nothing is left over on either side. In a US 10-year Treasury note auction it is the highest yield Treasury has to accept to sell the whole issue, and every winning bidder gets it.

Textbooks draw this as two crossing lines and stop. Very few markets actually show you their crossing point, but the US Treasury does, after every auction, down to the share of the last bids it filled. So this page explains the idea, works a simple hypothetical, and then follows a real $39.00 billion sale from the first bid to the clearing yield.

How it works

At a high price, more people want to sell than buy. The unsold amount is a surplus, and sellers who want to get rid of it cut the price. At a low price the reverse happens: buyers outnumber sellers, there is a shortage, and the price is bid up. The market-clearing price, also called the equilibrium price, is where neither pressure exists.

A worked hypothetical (not real data). Say buyers want Qd = 120 - 2P units and sellers offer Qs = 3P - 30. Set them equal: 120 - 2P = 3P - 30, so 5P = 150 and the clearing price is $30, where both sides want 60 units.

• At $35, buyers want 50 and sellers offer 75: a surplus of 25 units, so the price falls.
• At $25, buyers want 70 and sellers offer 45: a shortage of 25 units, so the price rises.

A continuous market never sits exactly at that price. It oscillates around it, one trade at a time, because new orders keep arriving and moving the balance. An auction does the calculation directly. Orders accumulate without matching, and the venue computes the single price that trades the most volume, or, in a Treasury auction, sells the whole amount on offer.

A worked example

On 7 October 2026 Treasury sold $39.00 billion of 10-year notes, a reopening of August’s issue. It received $108,068,999,700 of bids for $39,000,031,700 of notes, according to its own results release. Bids that only ask for whatever yield the auction sets, $334,593,700 of them, were filled first.

Then the competitive bids were stacked from the lowest yield up. Each bidder names the yield it will accept, and a lower yield means paying a higher price. Treasury kept accepting higher yields until the notes ran out. That happened at 5.300%, the clearing yield, or $94.864261 per $100 of face value.

Everyone below the line was filled in full; everyone at it was rationed. Bids at exactly 5.300% received 57.60% of what they asked for, and bids above it got nothing: $69.07 billion of the $107.73 billion of competitive bids, 64.11%, went home empty.

And every winner got the same yield. Half the accepted competitive amount was bid at 5.255% or lower, and 5% at 4.300% or lower, yet all of it was awarded at 5.300%. A bidder who would have accepted 4.300% still received 5.300%, because the auction finds one price for everyone.

Now set the price by hand and watch a surplus appear (a hypothetical, not what happened). Suppose Treasury had refused to pay more than 5.255% and every bid had stayed the same. Only the bids at or below that yield, about half of the $38.67 billion it accepted from competitive bidders, would have been filled, leaving up to roughly $19.3 billion of notes unsold. That is the textbook surplus from a price held away from clearing, sized with a real sale’s bids.

What happens at the market-clearing price

Everyone who wanted to trade at that price can, apart from the marginal orders. Buyers who would have paid more and sellers who would have taken less all trade at the one price. Only orders exactly at it compete for what is left, which is why Treasury’s last bids are shared out.

Nothing is left over, but demand is not gone. In the 7 October sale, demand at 5.300% was larger than the notes remaining, and demand at higher yields was much larger still. Clearing means the quantity sold equals the quantity bought at the price, not that every buyer was satisfied.

The price is information. It tells you where the two crowds balanced for that size, at that moment. A larger sale, or the same sale a day later, can clear somewhere else.

Do markets always clear?

Classical economics assumed they do, with prices and wages moving freely until surpluses and shortages vanish. Keynes and his followers argued that in the Great Depression they did not: wages and many prices are sticky, so a surplus of workers, unemployment, could persist for years.

The market-clearing wage is the labor-market version. It is the wage at which the number of people who want jobs equals the number of jobs offered. A legal minimum above it, or an employer paying above it on purpose to keep good staff (an efficiency wage), leaves more people wanting work than there are jobs.

Financial markets generally clear far faster than labor markets, because prices are posted, orders are anonymous and nobody has to renegotiate a contract to change their price. That is why traders can treat a quoted price as close to a clearing price, and why an economist would not do the same for wages.

The original data

The sample. Every single-price 10-year Treasury note auction from 13 January 2010 to 7 October 2026, new issues and reopenings, inflation-protected notes left out: 203 auctions, from Treasury’s Fiscal Data auction file. One 5 November 2019 sale that the file lists under an old 10-year note was a 3-year note auction, so it is left out. For the 67 new issues that TreasuryDirect’s own auction service also lists, the clearing yield, the share allotted at that yield and the bid-to-cover ratio matched on all 67.

The marginal bids are rationed, often hard. Bids at exactly the clearing yield received a median 46.67% of the amount they asked for. In 106 auctions (52.22%) they got less than half. The range ran from 0.48% on 8 May 2024 to 99.62% on 7 April 2010, and in no auction were they filled in full.

Most of the demand never trades. In the median auction, 61.01% of the competitive dollars bid received no notes, and the share ran from 53.91% to 73.20%. The bid-to-cover ratio reports the same thing the other way up. Every sale cleared with demand to spare, which is exactly what lets one yield be found where the last notes run out.

The clearing yield sat above most of the winning bids. In the median auction it was 0.048 percentage points above the median accepted yield, and 0.128 points above Treasury’s low yield, the level at or below which the lowest-yielding 5% of accepted competitive bids were placed.

The one-shot auction lands next to the continuous market. FRED’s 10-year market yield for the same day comes from end-of-day market quotes, not from the auction, which closes at 1 p.m. Yet in 140 of the 203 auctions (68.97%) the two were within 1.9 basis points (hundredths of a point), and in 193 (95.07%) 5 or fewer. None was 10 or more apart: the widest were 9.5 above on 9 April 2025 and 8.4 below on 9 November 2010. The median auction cleared 0.1 basis points below the market, and on 7 October 2026 it was 5.300% against 5.28%.

Two ways of finding a price, one continuous and one in a single calculation, kept ending up within a few hundredths of a point of each other. Every auction’s yields, amounts and gaps are in the auction vs market file, and the allotment shares in the 10-year auction file. The scale behind them is large: US bonds outstanding came to $61.2 trillion at the end of 2025 against $68.9 trillion of US stock market value, by SIFMA’s count cited in bond market.

What clearing means in the stock market

“Clearing” has a second meaning that has nothing to do with price. After a stock trade, a clearing house steps between buyer and seller, nets what each broker owes and stands behind the trade until settlement. Since 28 May 2024, most US stock trades settle one business day after the trade (T+1), under the SEC rule that replaced T+2.

Price clearing happens in the auctions. Exchanges run an opening and a closing auction where orders build up and one price is computed, the same calculation as the Treasury sale. Between them, every trade in the continuous session is a small local clearing: a market order meets the best resting limit order and the bid and ask update. The clearing price can sit in a different place in premarket and after-hours sessions, because different people are there.

A wide spread is two crowds failing to clear. The gap between bid and ask is the zone where nobody will trade. It widens after news and before announcements, when opinions diverge most, and a trading halt or a circuit breaker is the extreme case: no orderly price exists right now, so the venue stops and lets orders build up for an auction.

When it fails

Treating the last price as the value. The last trade is where one buyer and one seller balanced, for one size, at a moment that has passed. Sell a large holding and you discover the clearing price for your size, which can be materially lower, and the difference is paid as slippage.

Assuming a bid at the clearing price gets filled. In the 10-year auctions above, a bid at exactly the clearing yield got less than half its size in 106 of 203 sales.

Assuming a clearing price always exists. In a panic it can be far from anywhere displayed, or absent until the market reopens.

Expecting a thin market to clear near its last print. With few participants, and low elasticity, a single order can move the balance point a long way.

Confusing clearing with value. A clearing price is where orders met, not what the asset is worth.

Questions people ask

What happens at the market-clearing price?

Quantity bought equals quantity sold, so there is no surplus and no shortage. Orders priced better than it fill completely, and orders exactly at it are shared out: in the 7 October 2026 10-year auction they got 57.60%.

What is another name for the market-clearing price?

The equilibrium price. In auctions it is also called the clearing price or, for Treasury notes, the high yield or stop-out yield.

How do you find the market-clearing price?

Set quantity demanded equal to quantity supplied and solve, as in the hypothetical above ($30 and 60 units). A real auction does the same with orders: it stacks bids from best to worst and stops where the amount on offer runs out.

What is the market-clearing wage?

The wage at which the number of people who want jobs equals the number of jobs offered. A wage held above it leaves some people unable to find work, which is the labor-market version of a surplus.
