Bond Yields Are Surging — Here's What It Means for Your Mortgage
The 5-year Government of Canada bond yield remains above 3% as the Iran conflict escalates energy costs. Fixed mortgage rates have climbed across every major lender. Here's what the banks are charging today and what you should do now.
Key Takeaway
Fixed mortgage rates are elevated and climbing. The 5-year Government of Canada bond yield remains above 3.00% — driven by the Iran war and energy price spikes — and lenders have hiked fixed rates significantly. The lowest 5-year fixed in Canada is now 4.09%. If you're renewing in the 2025–2027 window, purchasing, or sitting on a variable rate, now is the time to act. The next Bank of Canada decision is April 29, 2026.
What's Happening Right Now
The benchmark 5-year Government of Canada (GoC) bond yield — the key benchmark used to price most fixed-rate mortgages — remains elevated above 3%. As of late March 2026, it stood at 3.209%, driven by the ongoing war in Iran and surging oil prices. Bond yields have been above 3% for weeks with no signs of easing.

BoC Policy Rate
Next decision: April 29
The Bank of Canada held its overnight policy rate at 2.25% on March 18 — the third consecutive hold. On April 1, the BoC's Summary of Deliberations revealed that Governing Council will "rely on judgment more than usual" for rate decisions given the unprecedented uncertainty from the Iran conflict. The next announcement is April 29, 2026. Fixed rates are driven by bond markets, not the policy rate, and bond markets are pricing in higher inflation risk.
Why Bond Yields Drive Your Mortgage Rate
Most Canadians don't realize that their fixed mortgage rate is tied to government bond yields — not the Bank of Canada overnight rate. Here's how it works:
Banks borrow money by issuing bonds at yields set by the market
When bond yields rise, it costs banks more to fund mortgages
Banks pass the cost to borrowers through higher fixed mortgage rates
Variable rates are tied to the BoC policy rate (Prime rate), which hasn't changed
"War, higher energy cost = inflation = higher bond yields = higher fixed rates" — Ron Butler, mortgage broker, as quoted by Canadian Mortgage Trends (March 21, 2026)

Why posted rates matter: Your bank's posted rate determines your penalty if you break your mortgage early. Even if you get a "discount," a higher posted rate means a potentially larger penalty. This is one reason we compare across 80+ lenders — not just the Big 5.
What's Driving the Surge
This isn't about domestic data — it's global forces pushing bond yields higher:
Geopolitical Tensions
The ongoing war in Iran has pushed oil prices sharply higher, feeding inflation expectations and driving bond yields above 3% across North America. Per Ratehub: "Bond yields remain elevated above the 3% mark as the war in Iran continues."
Inflation Repricing
Markets are repricing inflation and rate expectations. Higher energy costs are feeding through to consumer prices, reducing the chance of BoC rate cuts.
U.S. Treasury Spillover
Canadian bond yields typically move in tandem with U.S. Treasuries. As American yields climb, Canadian yields follow, directly impacting our fixed rates.
BoC Hike Risk
Markets are increasingly pricing in the possibility of Bank of Canada rate hikes as oil-driven inflation concerns build — a sharp reversal from the rate-cut expectations earlier this year.
Variable vs. Fixed: The Gap Is Widening Again
While fixed rates climb, variable rates have remained relatively stable — tied to the BoC policy rate which hasn't moved. This is shifting borrower behaviour:
Variable Rate Advantages Right Now
- Lower starting rate (as low as 3.35% discounted via broker)
- Growing gap means more savings upfront
- 43% of new originations in January chose variable
- Lower penalties if you need to break the mortgage
Fixed Rate Advantages Right Now
- Payment certainty — no surprises
- Protection if BoC starts hiking
- Short-term fixed (2-3 year) offers a middle ground
- Peace of mind in volatile times
What You Should Do Right Now
Renewing in the next 12 months?
Start now. Don't wait for maturity. Most lenders allow rate holds 120 days out, and brokers can shop across 80+ lenders for you. Every week you delay could cost you a higher rate.
On a variable rate?
You're currently benefiting from the growing gap. But if the BoC starts hiking, that advantage disappears quickly. Consider locking into a short-term fixed (2-3 year) for certainty.
Carrying a HELOC balance?
HELOC rates move directly with Prime. If rates do rise, your carrying cost increases immediately. Consider converting a portion into a fixed-term product now to cap your exposure.
Buying soon?
Get pre-approved immediately to lock in today's rate. Rate holds protect you while you shop. The longer you wait, the more likely you'll face a higher rate at closing.
🏠 First-Time Buyer? The GST Rebate Is Now Live
Bill C-4 received Royal Assent this month — the federal GST rebate for first-time homebuyers is officially in effect. You can save up to $50,000 on new homes priced up to $1 million, with partial rebates up to $1.5M. This applies to purchase agreements entered on or after March 20, 2025.
Combined with locking in a competitive rate now, first-time buyers have a unique window of opportunity.

Frequently Asked Questions
Will fixed mortgage rates keep going up?
As long as bond yields remain elevated, fixed rates will stay high or continue climbing. A de-escalation in geopolitical tensions or a drop in oil prices could bring relief, but as mortgage broker Ron Butler noted: "War ends = rate drops, but not all the way to February rates."
Should I choose variable or fixed right now?
It depends on your risk tolerance and timeline. Variable rates are currently lower, but carry the risk of BoC hikes. A short-term fixed (2-3 year) offers a middle ground: certainty without a long commitment. We can model both scenarios for your specific situation.
How do posted rates differ from discounted rates?
Posted rates are the bank's "sticker price" — often higher than what you'll actually pay. Discounted or special rates are what they offer to compete. However, posted rates matter because they're used to calculate your penalty if you break your mortgage early. A higher posted rate can mean a larger penalty.
How long does it take to get a rate hold?
Most lenders offer 90-120 day rate holds. We can secure one within 24-48 hours of your application. This locks in today's rate while you shop or wait for your closing date.
Is the Bank of Canada going to raise rates?
Markets are increasingly pricing in the possibility. While the BoC held at 2.25% on March 18, oil-driven inflation could force their hand. This would impact variable rates and HELOCs directly. Fixed rates are already reflecting this risk through bond yields.
