Among short-dated federal securities, the Government of Canada 4.0% bond maturing on 1 March 2029 (ISIN CA135087Q988) is notable for a coupon that sits well above the Bank of Canada’s 2.25% overnight rate. As at 15 September 2026 it traded at 101.33% of face value, a premium to par, with an approximate current Yield of 3.95% and a yield to Maturity of 3.433%. It has around 2.5 years left to run and is the current three-year benchmark, effective 1 April 2026. Canada is rated AAA (S&P), Aaa (Moody’s) and AA+ (Fitch).

What is this bond?

This is a conventional nominal Government of Canada bond. It pays fixed interest of 4.0% a year on each C$100 of face value, in two semi-annual instalments, and returns the C$100 principal at maturity on 1 March 2029. There is no call feature, so the yield to worst equals the yield to maturity.

With roughly 2.5 years of residual life, it is a short-to-medium security with modest duration. Its price will therefore move less for a given change in yields than a longer bond, while remaining closely tied to the near-term rate outlook.

Why is this bond in focus?

This security is the current three-year benchmark, a designation the Bank of Canada assigned with effect from 1 April 2026. Benchmark, or on-the-run, bonds are the specific issues that dealers use as reference points for a given maturity. They tend to be the most actively traded and most liquid at their tenor, and their yields anchor pricing across nearby maturities and act as a reference for the wider yield curve. That status is one reason a bond like this draws attention: it is a live gauge of where three-year Government of Canada funding costs stand.

Its 4.0% coupon, struck when yields were higher, now sits above prevailing three-year yields, which is why the bond trades above par. The relationship between that coupon and today’s market yield is the analytical thread running through this article.

What are Canadian bond yields doing?

Bank of Canada benchmark yields as at 11 September 2026 were 3.35% at two years, 3.44% at three years, 3.65% at five years, 3.74% at seven years, 3.95% at ten years and 4.28% at thirty years. The curve slopes upward, having normalised from the 2023–24 inversion, with the front end anchored near the 2.25% policy rate.

As the three-year benchmark, this bond’s yield sits close to that 3.44% three-year point. Its yield to maturity of 3.433% on 15 September 2026 is effectively the reference three-year Government of Canada yield in this dataset. That yield reflects the average overnight rate investors expect over the next three years plus a small term premium.

Interest rates and the Bank of Canada

The Bank of Canada held the overnight rate target at 2.25% at its decision on 2 September 2026, with the Bank Rate at 2.50% and the deposit rate at 2.20%. This was a hold. The Bank regards 2.25% as within its neutral range after easing from higher levels earlier in the cycle.

Governing Council said it stands “prepared to adjust Monetary Policy as needed,” pending its assessment of the recovery’s durability and the Inflation outlook, with no pre-commitment. The next decisions are scheduled for 28 October 2026, with a Monetary Policy Report, and 9 December 2026.

Because the bond’s 4.0% coupon exceeds the 2.25% policy rate, some investors read the premium as compensation the market once demanded when yields were higher, now being unwound as the bond ages towards par.

Inflation and the economic backdrop

Statistics Canada put headline CPI at 3.0% year on year for August 2026, released on 14 September 2026 and unchanged from the prior month. Core measures were softer: CPI-trim and CPI-median both stood at 2.0%, near the target midpoint, and CPI excluding gasoline ran at roughly 2.4%.

Gasoline, up 22.8% year on year but decelerating from 25.7%, is the main force keeping headline above core. Travel tours rose 26.1% and rents 2.8%, while grocery inflation eased to 2.8%. Real GDP grew at a 3.3% annualised rate in the second quarter of 2026, about 0.8% quarter on quarter, and Unemployment edged down to 6.4% in August, though the Bank still calls labour Demand subdued.

The tension between firm headline inflation and a soft labour market is central to how three-year yields, and therefore this benchmark, are priced.

Coupon versus market yield

The 4.0% coupon is fixed. The market yield changes. On 15 September 2026 the yield to maturity of 3.433% sat below the coupon, which is why the bond traded above par at 101.33%.

When a coupon exceeds prevailing yields, the price rises above C$100 so that the total return matches the market yield. A buyer at 101.33 collects the generous coupon but faces a small Capital loss as the price pulls down towards C$100 by March 2029. That pull-to-par effect is why the yield to maturity of 3.433% is lower than the 3.95% current yield, which measures only coupon against price. Coupon, current yield and yield to maturity are three separate figures, and the premium reflects the coupon’s size relative to today’s yields, not a judgement about value.

What could move this bond next?

As the three-year benchmark, its yield tracks shifts in expectations for the overnight rate over the medium term. Softer inflation or a weaker labour market could lower yields and raise the price; firmer inflation could push yields up. Benchmark status also means its yield can move on demand from investors seeking the most liquid three-year issue. The October and December decisions are key near-term events.

Key risks to watch

The main risk is that headline inflation near 3% proves stickier than the core measures imply, keeping the Bank on hold longer than expected. Tariff-related growth risks are two-sided. Federal Supply is heavy but stable, with planned gross bond issuance of around C$298 billion for 2026-27, a background influence on yields. The premium price also means the bond drifts towards par over time, which buyers should Factor into total return.

What investors may watch next

Investors may track the 28 October and 9 December Bank of Canada decisions, upcoming CPI and Labour Force Survey data, and whether this issue retains its three-year benchmark role as newer bonds are auctioned.
