Almost a Full Point, and Calgary Is Sitting on the Line

The Bank of Canada's statement on September 2 put it in one line: "Long-term bond yields have moved up globally, including in Canada."

The Middle East conflict is keeping oil high, and the Bank said in the same statement that the longer high oil prices and refinery margins persist, the greater the risk they spill into other prices. Statistics Canada reported on September 14 that the Consumer Price Index rose 3.0 per cent year over year in August, the same as July. The Bank's target is 2 per cent.

On September 16 the U.S. Federal Reserve raised the federal funds target range by a quarter point, to 3.75 to 4.00 per cent. Its statement: "Inflation remains elevated."

TD Economics published a note on September 10 arguing that part of this is not temporary. Vikram Rai, senior economist, wrote that "heavy government and corporate borrowing and weaker demand from traditional bond buyers are more structural. Yields are therefore likely to remain elevated." By his count, Canada's 10-year yield rose about 60 basis points from late February, against about 80 in the United States. Canada's smaller deficits, he wrote, provided "some insulation."

On September 10 the Canadian 10-year traded above 3.90 per cent. The year-end forecast in the Bank of Canada's own Market Participants Survey was 3.50.

Then on Thursday, September 17, the five-year fell ten basis points in a session, from 3.64 to 3.54.

Most Calgary apartment buildings that trade are financed with CMHC-insured debt, MLI Standard or MLI Select. The rate on both is set the same way.

A lender makes an insured loan. Insured loans can be pooled and funded through Canada Mortgage Bonds, which are guaranteed by CMHC on behalf of the federal government. That is why they trade close to Government of Canada bonds of the same term. The lender adds a spread. Five-year term, five-year curve. Ten-year term, ten-year curve.

Conventional, uninsured debt runs off the same curve with a wider spread, because the lender carries the risk CMHC would otherwise carry.

Ottawa built this pipe for rental housing on purpose. On September 26, 2023, Finance Canada raised the annual Canada Mortgage Bond limit from $40 billion to $60 billion and dedicated the increase to CMHC-insured multi-unit rental loans. Since 2024 the federal government has been buying Canada Mortgage Bonds itself, up to $30 billion a year, and it plans to keep buying up to $30 billion in 2026.

The government built the pipe, widened it, and is buying what comes out of it.

It still does not set the yield.

Residential lenders have already repriced. Canadian Mortgage Trends reported on September 12 that major banks raised fixed rates 10 to 20 basis points. One broker in the piece said some lenders had moved by close to 100. Mortgage broker David Larock: "The bond market is pricing in a lot more inflation going forward. The energy price spike is what I would call the primary cause, but there are other concerns."

CMHC lends the smaller of two numbers.

The first is a leverage cap. For an existing building:

• MLI Standard: up to 85 per cent loan to value, up to 40-year amortization.
• MLI Select at 50 points: up to 85 per cent, up to 40 years.
• MLI Select at 70 points: up to 95 per cent, up to 45 years.
• MLI Select at 100 points: up to 95 per cent, up to 50 years.

On an existing building, the higher Select tiers are earned with affordability commitments, energy retrofits or accessibility work. Each has a cost, and the affordability path lowers the rents the building can charge.

The second limit is coverage. Net operating income has to cover the mortgage payment by a minimum ratio. MLI Select's minimum is 1.10 for standard rental housing. For MLI Standard on existing buildings, lender guides put it at 1.10 to 1.20.

When the leverage cap is the smaller number, the rate barely touches the loan. The buyer gets 85 per cent whether the rate is 3.50 or 3.75.

When coverage is the smaller number, the rate sets the loan. Every basis point raises the payment, the payment fails the test, and the loan shrinks until it passes.

For each cap rate there is an interest rate where the two limits meet. Below it, leverage binds. Above it, coverage binds.

CBRE's Q2 2026 report puts Calgary low-rise multifamily at 4.75 to 5.25 per cent for Class A and 5.00 to 5.50 for Class B.

On an 85 per cent, 40-year loan at 1.10 coverage, which is MLI Standard or MLI Select at 50 points, the line sits at:

• 4.12 per cent for a 4.75 cap.
• 4.48 for a 5.00 cap.
• 4.83 for a 5.25 cap.

If the lender underwrites MLI Standard at 1.20 coverage, the line drops to 3.54, 3.88 and 4.21.

One lender's MLI Standard guide, updated August 18, before the latest move, put insured rates at 4.50 to 5.25 per cent.

At 1.10 coverage, the 4.75 and 5.00 lines are already below that range. Only the 5.25 line falls inside it. At 1.20, all three are below it.

Calgary Class A low-rise, on standard insured terms, is past the line. Coverage is setting the loan, and the bond is setting coverage. Class B is sitting on the line.

One detail pushes the line lower. CMHC does not underwrite the seller's NOI. It underwrites its own, with its own vacancy, expense and reserve assumptions, and that number is usually lower. A lower NOI against the same price is a lower effective cap rate, and a lower cap rate means coverage binds sooner.

Once coverage binds, a quarter point on the rate, starting from 4.50 per cent, reduces the maximum loan by:

• 2.5 per cent on a 25-year amortization.
• 3.4 per cent on 40 years.
• 3.7 per cent on 45 years.
• 3.9 per cent on 50 years.

The longer the amortization, the bigger the loan, and the more of it disappears when the rate moves. On a 50-year loan about 90 per cent of the early payment is interest, so a change in the rate reaches almost the entire payment.

The 45- and 50-year terms are what let buyers stretch to today's prices. They are also what make those prices most sensitive to the bond.

For comparison, a quarter point on the cap rate itself, from 4.75 to 5.00, is a 5.0 per cent drop in value. From 5.00 to 5.25 it is 4.8. A buyer at maximum insured leverage can lose most of that through the loan alone, before the cap rate moves at all.

Conventional buyers never had the line. At 75 per cent, 25 years and 1.20 coverage, coverage binds above roughly 2.3 to 3.3 per cent across the same cap range. On conventional debt, every basis point has been coming off the loan all year.

All of this describes a buyer using insured leverage to its limit. Plenty of buyers do not.

A REIT, a pension fund or a large private owner buying at low leverage or with cash prices off the return it wants. Cap rates move slowly. CBRE reported that national multifamily cap rates held effectively flat in Q2 2026. For that capital, a bond move reaches price late, if at all.

Yields also fall. Ten basis points came off the five-year on September 17 alone.

And income can repair a coverage test. If NOI grows, the loan grows with it.

That last one is the weakest defence in Calgary right now. CMHC's 2025 Rental Market Report put Calgary's purpose-built vacancy rate at 5 per cent, unchanged from 2024. The City of Calgary, citing CMHC, shows 4.6 per cent in 2024 and 5.1 in 2025. The two do not agree on the change. They agree on the level. CMHC projects 5.7 per cent for 2026 and 6.2 for 2027.

The average two-bedroom rent in CMHC's survey was $1,914, a change CMHC flagged as not statistically different from zero. Purpose-built supply grew 11 per cent in 2025, the fastest growth in decades. Landlords, CMHC reported, "adjusted rents and provided incentives to keep existing tenants."

No NOI growth is coming to rescue the coverage ratio this year.

The counterargument holds for the low-leverage buyer. On most 30 to 75 door buildings in this city, the insured buyer is the one setting the price.

As I was finishing this piece, I read a post from Bob Knakal. He has personally sold more than 2,400 buildings in New York over a 42-year career, representing sellers only.

"A seller's broker needs a strategy," he wrote. "But the strategy should never become a script."

The script he meant: "Four weeks of marketing. Bid deadline. Second round. Best-and-final. Contract. Closing. It looks organized." The mistake, in his words, is "deciding the entire process before the market has had an opportunity to speak."

In New York his point is about competition. In Calgary this month, it is also about time.

The same lender guide puts MLI Standard at four to eight weeks from application to CMHC commitment, and six to twelve weeks from first contact to closing. Until the rate is locked, the buyer does not know what the loan will be.

The five-year closed at 3.36 on Friday, August 21. It closed at 3.65 on Tuesday, September 15. Twenty-nine basis points in under four weeks.

A buyer who bid in late August on a building near the line underwrote one loan. If coverage now binds, 29 basis points on a 40-year amortization is about 4 per cent of that loan. The buyer can borrow less than when they signed. The retrade that follows is not bad faith. It is arithmetic.

A process with deadlines set on the calendar is running on a clock the bond market does not use.

Knakal gave an example. Guidance in the low-to-mid $40 millions. Everyone at $44 to $45 million, except one buyer at $50 million with a strong deposit and limited contingencies, who can close quickly. "Why automatically run three more rounds? Doing so might jeopardize the best deal."

In Calgary this month, "can close quickly" has a specific meaning. It depends on the loan.

What a seller needs to know about each bidder, before choosing one. Which program: MLI Standard, MLI Select at what tier, or conventional. What amortization. Whether the loan is sized by leverage or by coverage on the lender's NOI, not the seller's. How far the offer sits from the line. When the rate locks.

The highest bid near the line is the one most exposed to the next oil headline. A slightly lower bid sized by leverage, with room under the line, can close at its number when the higher one cannot.
