The TSX Gained Friday, But the Real Story Was a 5.18 Percent Treasury Yield

Sep 28, 2026 5 min The Market Desk

The Brief

TSX closed Friday at 35,800.89, up 94.43 points, capping a volatile week driven by bond market swings rather than domestic news.
The US 10-year Treasury yield hit 5.18 percent Thursday, the highest level since the 2008 financial crisis.
Canadian 10-year yields touched a 34-month high of 4.00 percent, before easing to 3.93 percent Friday as oil prices pulled back.
TSX technology stocks gained roughly 9 percent for the week, the standout sector performer against a mixed broader tape.

The TSX Composite closed Friday at 35,800.89, up 94.43 points, a gain that undersells how volatile the week actually was underneath it.

The US 10-year Treasury yield hit 5.18 percent Thursday, the highest level since the 2008 financial crisis, before easing as oil prices pulled back into Friday. The Dow gained 0.9 percent Friday, snapping a three-week losing streak, while the S&P 500 and Nasdaq each added 0.5 percent, both posting gains for the week despite the bond selloff that dominated the middle of it.

Why the TSX Held Up Better Than the Bond Market Suggested It Should

Canadian 10-year yields tracked the same selloff, touching 4.00 percent Thursday, a 34-month high, before easing to 3.93 percent Friday as falling oil prices reduced inflation concern and helped halt the broader bond market slide.

The Canada-US 10-year spread now sits at roughly 1.25 percentage points, a genuine divergence rather than noise. The Federal Reserve is facing hotter, tariff and inflation driven pressure than the Bank of Canada, which held its own policy rate at 2.25 percent this month on comparatively contained core inflation. That gap in bond market pressure is a large part of why the TSX absorbed a yield shock that hit US equities harder earlier in the week.

The One Sector Carrying the Index

Technology stocks gained roughly 9 percent for the week, according to Adam Ludwick, director of asset allocation at NEI Investments, the standout performer against a mixed broader tape. Retail trade lagged: Statistics Canada reported July retail sales fell 0.7 percent, though an early estimate points to a 1.3 percent rebound in August.

TSX Composite levels over the past month show a index that gave back some of its late-August highs before stabilizing into the yield spike, a pattern worth watching heading into the final quarter.

What Monday Should Watch

Oil has pulled back from its September peak above $108, a move that helped ease the bond selloff late in the week. Whether that holds through the next several sessions matters more for Canadian yields, and by extension mortgage and lending rates, than any single data release this week. The next Bank of Canada decision lands October 28, and most economists expect an eighth straight hold barring a sharp shift in either the trade file or the energy market.

What They're Feeling

Clients hearing about the Treasury yield spike assume their bond holdings took a hit and that equities should have fallen too, without seeing that the TSX actually gained on the week.

What to Say

The bond market had a rough week. The US 10-year yield hit its highest level since the financial crisis, and Canadian yields touched a 34-month high before easing. That does affect bond prices directly, since yields and prices move in opposite directions. But the TSX actually closed the week higher, helped by technology names and by the fact that Canadian yields did not rise as much as US yields. Let us look at how your specific fixed income holdings were affected rather than assuming the headline story applies evenly.

Who's Affected

High impact: Clients holding longer-duration bonds or bond funds directly, where price moves inversely with the yield spike.

Mixed impact: Balanced portfolio holders, where equity gains this week partially offset fixed income price declines.

Potential benefit: Clients with Canadian technology sector exposure, which was the standout performer this week.

Action Checklist

Review duration exposure for clients holding individual bonds or bond funds directly.

Confirm which clients hold technology sector exposure and note the week strong performance for the next review.

Flag any client asking about the yield spike for a plain-language explanation of the yield and bond price relationship.

Subject: What Last Week Bond Market Move Means for You

Hi [Client Name],

Following up on the bond market headlines from last week. The US 10-year Treasury yield hit its highest level since the financial crisis, and Canadian yields also rose before easing Friday. I have reviewed your specific fixed income exposure and want to walk through what this means for your holdings directly, rather than the market in general.

Client Profiles to Target

Self-directed investors holding individual bonds or bond funds who may not understand why a yield spike affects their holdings, and equity investors unaware that Canadian technology names outperformed sharply this week.

Opening Line

Bond yields just hit levels not seen since the financial crisis. Do you know how that move affected the value of any bonds or bond funds you hold directly?

Value Proposition

Self-directed bond investors often do not realize how sensitive their holdings are to a yield move of this size until the account statement shows it. An advisor who can explain the mechanism before it shows up on a statement, and who can point to where the actual gains were this week, offers a level of context a self-directed platform does not provide on its own.

Discovery Questions

Do you hold any bonds or bond funds directly, and do you know their average duration?

How did you react when you saw the Treasury yield headlines last week?

Do you know which sectors of the Canadian market actually gained last week, despite the bond volatility?

Subject: Last Week Bond Move, in Plain Terms

Hi [Name],

The US 10-year Treasury yield hit its highest level since the financial crisis last week, and Canadian yields moved too before easing. If you hold any bonds or bond funds directly, this is worth fifteen minutes to walk through, especially since the TSX itself still finished the week higher on the back of technology names. Happy to explain what happened and what it means for your specific holdings.
