Impact is the average of the four parts, rounded, plus one point when Canada is directly hit on two or more channels, up to 10.

Two separate scales from 1 to 10. Strature never multiplies or merges them.

What changed

Dated, newest first

  1. 30-year par yield 5.67% on 7 Oct, 10-year 5.31% on 5 Oct; 5.33% and 5.00% on 23 Oct; 5.37% and 5.05% on 28 Oct 2026. [2]
  2. FOMC kept its range at 3.75-4% on 28 Oct 2026. [12]
  3. Implementation note, 28 Oct 2026: standing overnight repo operations at 4.0%; Treasury bill purchases, when appropriate, 'to maintain an ample level of reserves'. [13]
  4. Impact 9 to 8.
  5. Marketable Treasury debt US$31.83tn on 30 Sep 2026. [8]
  6. FOMC raised range to 3.75-4% on 16 Sep 2026; standing repo at 4.0%. [3]

Why it matters

The world's main safe asset has strains: hedge fund leverage is near record highs and liquidity thinned for a time when the Iran conflict hit rates. Long yields touched 5.67% in early October, then fell. A seizure that forces the Fed to buy bonds, as in March 2020, remains a tail case.

Why Likelihood 3 Pushes: hedge fund leverage near record highs, higher term premiums, thin 2-year depth, Fed hikes, a clearing deadline on 31 Dec 2026. Brakes: robust dealer capacity, yields below their October highs on 28 Oct [2].

Why Impact 5 Threshold case: a 2020-style seizure forcing Fed purchases. Held across regions (TIC). Depth: no source sizes the sales or price move (estimate), 3. The Fed as backstop says who ends it, not what holders must replace. Canada hit on one channel (US$464.6bn of holdings).

The other facts on file (3)
  • Hedge fund gross leverage near all-time highs in 2025 Q3, skewed to the largest funds. [1] (8 May 2026)
  • Treasury liquidity initially deteriorated after the Iran conflict, then recovered; 2-year depth near first quartile. [1] (8 May 2026)
  • Canada held US$464.6bn of Treasuries in Aug 2026. [9] (31 Aug 2026)

Three scenarios and their signposts

  1. S1

    Calm with spikes

    Volatility returns but liquidity recovers in weeks.

  2. S2

    Clearing strain

    The 31 Dec 2026 cash clearing deadline brings repo friction.

  3. S3

    Seizure

    A sell-off and funding loss force deleveraging; the Fed buys.

The signposts of each scenario
PathSignpost
S130-year stays below its October high of 5.67%
S2SEC delay or relief notice before the date
S3FOMC statement citing the smooth functioning of markets for Treasury securities

No probability is given for the three paths.

The other side

Central clearing should make the market sturdier once in place. High yields give savers and pension funds, Canada's included, better returns on safe assets. A Fed backstop is a known playbook from 2020 [5]. Strature is a research firm, not a licensed adviser; nothing on this card is a recommendation to buy or sell any security.
