What the October 26 Treasury Auction's Indirect Share Measures

Treasury's 26 October two-year note auction awarded about 45.68% of its competitive allotment to indirect bidders. Calling that a 45.68% foreign-buyer share would add information the category does not contain. Treasury's indirect-bidder category describes how a competitive bid was submitted, not whether the bidder is foreign.

The distinction matters before an auction statistic becomes a claim about overseas demand, the dollar or an equity option. The Treasury auction FAQ explicitly includes both foreign and domestic customers in the indirect category. A change in that category alone cannot identify a change in foreign participation.

Reproduce the competitive-award share

The official auction record identifies a two-year Note, CUSIP 91282CRU7, with an auction close on 26 October 2026, issue date of 2 November and maturity on 31 October 2028. Its competitive awards are recorded at par, meaning the securities' face amount rather than their purchase cost.

Primary-dealer competitive awards (P): $8,818,075,000.

Direct-bidder competitive awards (D): $28,027,002,700.

Indirect-bidder competitive awards (I): $30,981,323,300.

Total competitive awards within the offering (T): $67,826,401,000.

The three categories reconcile exactly:

P + D + I = T

For the October 26, 2026 two-year note, indirect awards of $30,981,323,300 divided by total competitive awards of $67,826,401,000 give 45.68%, rounded.

I / T x 100 = 45.67738055%

This is author arithmetic from Treasury's dollar fields. The denominator is the competitive-award subtotal. Dividing by the announced $69 billion offering instead would give about 44.90%, a different calculation. Neither result supplies a foreign-buyer percentage. This article uses no foreign-allotment figure for the auction.

Routing and domicile are separate classifications

Treasury defines an indirect bidder as a customer submitting a competitive bid through a primary dealer or direct submitter. Foreign and international monetary authorities bidding through the Federal Reserve Bank of New York are included, but so are domestic customers using the relevant route.

The direct-bidder category also includes both domestic and foreign bidders. Treasury distinguishes direct bidders' own-account bids from primary dealers' proprietary bids. Replacing the indirect label with “foreign” and the direct label with “domestic” would misclassify both categories.

The labels answer a submission question. A domicile classification asks where the bidder is based. The following fictional records show why one classification cannot recover the other.

Two complete fictional auctions

Assume two invented auctions, A and B, each award $100 billion of competitive par. Every dollar belongs to exactly one routing category and one domicile group. For this illustration only, all primary-dealer proprietary awards are domestic. There are no noncompetitive awards or Federal Reserve own-account awards. These assumptions isolate the classifications; they do not reconstruct the October auction or describe all real bidders.

Fictional auction A has the following complete record:

• Indirect awards total $60 billion: $40 billion domestic and $20 billion foreign.
• Direct awards total $30 billion: $20 billion domestic and $10 billion foreign.
• Primary-dealer proprietary awards total $10 billion: $10 billion domestic and $0 foreign.

The routing totals add to $100 billion. Domestic awards total $70 billion and foreign awards total $30 billion. The indirect share is 60 / 100 x 100 = 60%; the foreign share is 30 / 100 x 100 = 30%.

Fictional auction B changes only the routing of $20 billion of domestic awards:

• Indirect awards total $40 billion: $20 billion domestic and $20 billion foreign.
• Direct awards total $50 billion: $40 billion domestic and $10 billion foreign.
• Primary-dealer proprietary awards total $10 billion: $10 billion domestic and $0 foreign.

Again, routing totals add to $100 billion. Domestic awards remain $70 billion and foreign awards remain $30 billion. The indirect share is now 40 / 100 x 100 = 40%, while the foreign share remains 30%.

In the fictional example, the indirect share falls from 60% to 40% while foreign competitive awards remain $30 billion in each auction. That is a 20-percentage-point routing-share decline with no change in either the assumed foreign dollar award or foreign share. These are monetary amounts, not counts of investors.

The example establishes a possible result under stated assumptions. It does not establish what caused the real October allocation, how foreign investors behaved, or how awards changed from a prior auction.

Use the separate investor-class record for a foreign-participation question

Treasury points readers seeking foreign auction participation to its Investor Class Auction Allotments. Those tables have their own release schedule and are ordered by issue date. The page lists fields including security type, CUSIP, maturity, total issue amount and designated investor classes.

Match the security and measurement basis before comparing an investor-class table with an auction result. For this note, the auction date is 26 October but the issue date is 2 November. A date-only match could select a different record. Keep competitive awards, noncompetitive awards and the relevant denominator identified rather than assuming every table uses the competitive subtotal calculated above.

No investor-class workbook is analysed here. There is no claim that a particular dated foreign-allotment row was available, that foreign buying rose or fell, or that foreign holdings changed in secondary trading. Auction awards and later transactions would require different evidence.

Our Treasury-bill rate article addresses another denominator problem: a bill's discount rate, investment rate and holding-period return. The reserve-balances article concerns the Fed's balance sheet. Neither is a substitute for a bidder-classification record.

Keep the auction and option records separate

The original analysis was prepared at 07:08:07 Australia/Brisbane on 27 October; the dated auction fields were independently rechecked on 1 November. At that original preparation time, the latest completed scheduled NYSE core equity session was Monday, 26 October, ending at 4 p.m. Eastern Daylight Time, or 6 a.m. Tuesday in Brisbane. That is a calendar boundary, not a Treasury-market close or a closing-price observation.

Treasury's record gives a competitive bidding deadline of 1 p.m. Eastern Time on 26 October, equivalent to 3 a.m. on 27 October in Brisbane. The record does not give a publication time of day. The deadline must not be presented as a measured publication timestamp. No stock, Treasury-price, option-price or implied-volatility reaction is measured here.

An option requires its own underlying, strike, expiry, multiplier, exercise and settlement terms, plus a timestamped bid, ask and available size. The Options Industry Council's pricing guide identifies several premium inputs, including the underlying price, time, implied volatility and interest rates; an auction routing percentage supplies no contract valuation.

Liquidity must be checked for the particular series. A broad auction statistic does not establish an achievable option entry or exit price; see the bid-ask guide.

Concentration remains a separate portfolio question. Several options and funds can expose an investor to overlapping issuers or economic risks regardless of the auction's bidder mix.

The time horizon must fit the contract and the investor's need for cash. This dated award record does not identify the price or funds available at a later expiry or spending date.

Funding suitability must cover the relevant obligations. Buyers can lose the premium; some short positions can lose more, including theoretically unlimited loss on an uncovered call. FINRA's assignment explanation covers exercise and delivery obligations. The SEC's leveraged-investing bulletin explains premium-loss, writer-loss and margin risks. American-style short options can be assigned before expiration. Settlement can require cash or shares; spreads, commissions, fees, taxes and broker policies can alter results. Options can be unsuitable when the investor cannot tolerate the losses, fund the obligations or bear a costly exit.

Sources and scope

Material source passages and the exact dated auction row were independently rechecked on 1 November 2026 Australia/Brisbane. The dated official auction query supplies the released dollar fields and security dates, as originally retrieved on 27 October and confirmed on 1 November. It does not label the record preliminary or revised, and this article does not certify that it can never be corrected. The Treasury FAQ supplies bidder definitions; the investor-class portal identifies the separate dataset and its issue-date ordering. NYSE hours establish the scheduled equity-session boundary. OIC pricing and FINRA assignment guidance and SEC loss-risk guidance support the contract and risk limitations.
