Premium and Discount Bonds
Obligations à prime et à escompte in French
Quick definition
A premium bond trades above its face value because its coupon is richer than current market rates; a discount bond trades below because its coupon is leaner. Both can carry the same yield, yet in a taxable Canadian account they are taxed very differently.
Why a bond leaves par
A bond's coupon is frozen the day it is issued, but market rates keep moving. When today's rates sit below a bond's coupon, that bond pays more cash than anything newly issued, so buyers bid its price above 100: a premium bond. When rates sit above the coupon, the bond underpays, and its price sinks below 100 to compensate the buyer: a discount bond.
The price adjustment is exactly calibrated. Whether the price sits at 104 or at 96, the yield to maturity ends up in line with the market, because the gain or loss between the price paid and the face value repaid at maturity fills the gap the coupon leaves. Before tax, a premium bond and a discount bond with the same yield and credit quality are the same investment in different wrappers.
The pull to par
Whatever a bond's price today, it has one fixed appointment: face value at maturity. As the date approaches, a premium bond's price glides down toward 100 and a discount bond's price climbs up toward it, a drift called the pull to par. It is not a market move and requires no news; it is simply the shrinking number of above-market or below-market coupons left to collect. Rate changes push prices around along the way, but the pull to par always wins in the end.
The Canadian tax angle
In a taxable account, the wrapper matters a great deal. A premium bond front-loads your return into big coupons, every dollar of which is taxed at your full marginal rate as interest. Then, at maturity, you take a guaranteed capital loss (you paid more than 100 and got 100 back), and under capital gains tax rules that loss can only offset capital gains, not the interest you were taxed on. High tax now, restricted relief later: the premium bond is tax-inefficient by construction.
A discount bond flips the arithmetic. The coupons are smaller, so less of your return is taxed as interest each year, and the remainder arrives at maturity as a capital gain, only half of which is taxable. Same pre-tax yield, meaningfully more kept after tax.
The market knows this. Discount bonds command slightly lower pre-tax yields than equivalent premium bonds, because taxable investors will pay up for the tax-efficient wrapper, and it is why ETF providers build and market discount-bond funds aimed at non-registered money (as of July 2026).
In a registered account (RRSP, TFSA, RRIF and the rest), none of this matters. No tax is levied on the coupons or the gain, so premium and discount bonds with the same yield are interchangeable, and you simply take whichever offers the better yield for the risk.
In Canada
The sharp rate rise of 2022 pushed most of the existing Canadian bond market below par, creating an unusually large supply of discount bonds. Fund providers responded with discount-bond ETFs built specifically for taxable accounts, and years later a large share of outstanding Canadian bonds still trades below par (as of July 2026). It is one of the few cases where a market accident created a lasting tax planning tool for ordinary investors.
Worked example
Two 5-year bonds each yield 4% to maturity. The premium bond has a 5% coupon and costs about 104.50, so $10,449 per $10,000 of face value; the discount bond has a 3% coupon and costs about 95.51, so $9,551. Assume a 40% marginal tax rate and a taxable account.
The premium bond pays $2,500 of coupons over five years, costing about $1,000 in tax, and matures with a $449 capital loss that is only useful if you have capital gains to offset. The discount bond pays $1,500 of coupons, costing about $600 in tax, plus a $449 capital gain at maturity, of which half is taxable, adding roughly $90 of tax. Total tax: about $1,000 versus $690, so the discount bond keeps you a few hundred dollars ahead on an identical pre-tax return. These figures are approximate and ignore the timing of payments, but the direction is the point: in taxable money, the discount wrapper wins.
