So you have your number. The remaining question — the one the September hold genuinely changed — is how long to commit to it.
The case for a short term has been the same all year, and it was a good case: take one, two or three years, keep your options open, and renew again into the lower rates that are coming. That argument depends entirely on rates being lower when you get there. It is a bet, and until September 2 it was a bet with the wind behind it.
Look at what the bet costs and what it pays. A two-year fixed at 3.89% saves you about $31 a month against the five-year fixed. Then, two years from now, you renew again on a smaller balance with eighteen years left.
Read that middle pair of columns slowly, because it is the whole argument. The short term saves you around $30 a month and exposes you to around $140 a month of movement in either direction. You are risking roughly four and a half times what you are saving, on a two-year term, and closer to six times on a three-year one. When the next move was reliably going to be a cut, that lopsidedness was the point — you accepted a small give to collect a large get. With the Bank now describing its risks as two-sided, the same trade is much closer to a coin flip.
None of this makes the five-year fixed the right answer. It makes the short term a position rather than a default, and it deserves to be chosen deliberately. It helps to know that the professionals disagree too: a forecast compilation updated in late August by nesto showed BMO, CIBC, RBC and TD all expecting 2.25% through December, while National Bank and Scotiabank projected increases before year-end. Reasonable people are reading the same data and landing in opposite places.
One more thing worth holding onto: there are only two scheduled announcements left this year, October 28 and December 9. If your renewal date falls before spring, the number of decisions that could still move your rate is small enough to count on one hand.
