Bond yields have been going vertical.
By early Thursday, the
5-year yield—which
influences long-term fixed rates—was up as much as 20+ basis points in
less than 48 hours. That's an unusual move and it was driven by
optimistic economic comments from the U.S. central bank.
This spike in yields has led dozens of lenders to announce fixed rate increases. The most notable today was RBC, which is
boosting certain discounted fixed rates by 20
basis points on Monday.
But it’s not only bond yields that are flying. So is the 5-year
swap spread, and that also has mortgage rate implications.
Swaps Basics
A “swap” (interest rate swap) is an agreement to exchange two
different types of interest payments: fixed-rate payments and
floating-rate payments. Financial institutions buy swaps to hedge
interest rate risk and lock in profits.
A simplified example of hedging: A bank with 5-year fixed
mortgages receives fixed-rate payments from borrowers. That same bank
also has short-term deposits. If short-term rates rise, the bank would
have to pay higher rates to depositors, but be left with the same fixed
rate payments from its mortgages. To solve that problem, the bank buys a
swap that lets it receive floating-rate payments (at a higher rate than
it has to pay out to depositors). In exchange, the bank must give its
fixed-rate payments to the swap seller.
Why swaps matter
The difference between the 5-year swap rate and the 5-year government yield is called the "swap spread."
When the swap spread gets wider, fixed mortgages can become more
expensive to hedge, other things being equal. That often happens when
bonds sell off and yields soar. Lenders then pass along that added cost
to borrowers.
Here’s a chart of the swap spread from earlier Thursday. As you can see, it has been making new relative highs.

spreads
may continue to widen if Canadians rush to lock in low rates. In that
scenario, banks would have even more fixed-rate mortgages to hedge in
the swap market.
It’s hard to say how long rising yields and widening swap spreads
will exert upward pressure on rates. So if you need a mortgage in the
next 180 days, call your broker or banker soon for rate hold. Some
protection is better than none, and you can always cancel a rate hold if
needed.
