What the Odds Mean, Who Pays First, and What to Check Before the Bank of Canada Decides

Swap market data on Tuesday, October 20 put the odds of a Bank of Canada rate hike on October 28 at 80 per cent. The move would lift the policy rate by 25 basis points, from 2.25 per cent to 2.50 per cent, and end a run of seven consecutive holds. It would also be the Bank's first increase since July 2023. By Wednesday morning, the same measure had climbed higher still.
For anyone holding a variable-rate mortgage or a home equity line of credit, this is not a forecasting contest. It is a payment question. The prime rate that most variable products are priced from has historically moved the day after a Bank decision, and the cost lands on your statement soon after. Who feels it, how much, and when depends almost entirely on the type of product you hold.
This piece covers four things: what the 80 per cent figure actually measures, why it jumped over a single weekend, how a quarter point flows through to each kind of borrowing, and what to gather in the seven days before the 9:45 a.m. ET announcement. It does not predict the decision. Neither do the markets.

The headline number comes from the overnight index swap market, where traders bet on where the Bank's policy rate will sit after each decision. Reuters reported on October 20 that swap pricing implied an 80 per cent chance of a 25-basis-point hike on October 28, and that the gap between Canada's two-year bond yield and its U.S. equivalent had narrowed to 146 basis points from about 160 earlier in the month. A basis point is one hundredth of a percentage point, so 25 basis points is 0.25 percentage points.
Here is the mechanism in one line. If traders price a post-decision rate partway between today's 2.25 per cent and a possible 2.50 per cent, the distance travelled is read as the probability of a hike.
On October 19, The Globe and Mail reported Bloomberg data positioning the overnight rate at 2.455 per cent after the October 28 decision and 2.614 per cent after the December 9 decision. That 2.455 figure sits about four-fifths of the way to 2.50. That is where the odds come from.
Two cautions matter. First, an 80 per cent probability means roughly one-in-five odds of a hold. One-in-five is not a rounding error. Second, the number moves daily, which is why different outlets quote different figures for the same week.
The pattern is the story. In roughly one week, a hike went from an outside chance to the market's base case.

The repricing had three triggers, and they arrived in quick succession.
The first was the Governor. Speaking to reporters from the IMF and World Bank meetings in Bangkok on Saturday, October 17, Tiff Macklem said the Bank expects to raise its inflation forecast significantly because of persistently high oil and refined-fuel prices. According to Reuters' account of the call, he framed the October question as whether inflation will return to target on its own or whether the Bank will have to raise rates to "nudge the path." Markets heard a central bank preparing the ground.
The second was September's inflation report on Monday, October 19. Headline inflation rose to 3.1 per cent, above the Bank's 1 to 3 per cent band, but slightly below the 3.2 per cent economists expected. Energy did most of the work: gasoline was up 27.8 per cent from a year earlier. Strip gasoline out and inflation was 2.2 per cent. The Bank's preferred core measures, CPI-median and CPI-trim, came in at 1.9 and 1.8 per cent. On its own, that report argued for patience.
The third signal overrode it. The same afternoon, the Bank published its quarterly surveys. In its Canadian Survey of Consumer Expectations, consumers' long-term inflation expectations rose to match their already elevated short-term expectations. The companion Business Outlook Survey found that firms' one-year-ahead expectations rose again in September, while their five-year expectations stayed roughly unchanged. Roughly half of firms said they plan to pass some or all of their war- and tariff-related cost increases on to customers.
That distinction is worth getting right. Much of the coverage credits the business survey with the jump in long-term expectations. It was the consumer survey. Central banks watch long-term expectations closely because once households expect higher inflation years out, it becomes harder to bring down.

Forecasts changed faster than most published summaries. On the morning of October 19, several big-bank economists were still writing that the Bank could afford to wait. By that evening, three had reversed. Bloomberg reporting carried by the Financial Post said the Bank of Montreal, Royal Bank of Canada and Desjardins all flipped their October calls from hold to hike, while the consensus in a recent Bloomberg survey still pointed to a hold.
The case for a hold is not trivial. TD Securities senior economist Robert Both argued on the bank's MoneyTalk program that core inflation below 2 per cent, a more fragile labour market and scant evidence of price pressures spreading beyond energy leave little cost to waiting until December or January.
The case for a hike rests on the forward view. Scotiabank's Derek Holt has argued that once a move is heavily priced, not delivering it would effectively loosen financial conditions, which the Bank would struggle to justify.
Read the table as a range of outcomes, not a scorecard. For a household budget, the useful conclusion is narrower: a hike is now a live possibility worth preparing for, and it may not be the last.
The Bank itself flagged that risk at its previous decision, covered in Bank of Canada Holds at 2.25% and Warns Consecutive Rate Hikes Possible.

Think of the transmission as three links in a chain.
Link one: the policy rate. The Bank announces at 9:45 a.m. ET on October 28, alongside a new Monetary Policy Report, according to its published 2026 schedule. The next scheduled decision is December 9.
Link two: prime. Big-bank prime sits at 4.45 per cent today. The pattern in TD's published prime history is consistent: after the October 29, 2025 cut, TD prime fell to 4.45 per cent effective October 30; after the September 17, 2025 cut, it moved effective September 18. Each change matched the Bank's move. If the Bank raises by 25 basis points, prime would be expected to rise to 4.70 per cent, most likely on October 29. That is a historical pattern, not a contractual guarantee.
Link three: your product. This is where borrowers diverge. The same quarter point produces three very different experiences.
The first row is what the headline means by "resetting variable payments." The second row is the one most often misunderstood.

The figures below show the approximate change in a monthly payment from a 25-basis-point increase. They assume monthly compounding and a full 25-year amortization. Your own number depends on your remaining balance, remaining amortization and how your contract compounds interest, so treat these as scale, not a quote.
Two rates are shown deliberately. The 4.45 per cent column matches prime. But most variable borrowers pay prime minus a discount; the best five-year variable on Ratehub's October 21 comparison was 3.43 per cent. On a $500,000 balance, that puts a typical increase closer to $67 a month than $70. Under semi-annual compounding, the $500,000 example at 4.45 per cent works out to about $70.
Adjustable-payment variable. This is the straightforward case. The payment rises to keep your amortization on track. At roughly $40 to $110 a month on the balances above, a single quarter point is manageable for most households. Several in a row are a different conversation.
Fixed-payment variable. Here the payment does not move. Some lenders build their variable product this way by default; RBC's variable-rate mortgage, for example, keeps the payment fixed for the term and directs more of it to interest when prime rises. The last column of the table shows that shift: on $500,000, about $104 a month that used to pay down principal now pays interest instead. You will not feel it in your bank account. You will see it on your balance.

You will see it on your balance.
Fixed-payment variable mortgages have a trigger rate: the rate at which your payment only covers interest. According to the Financial Consumer Agency of Canada, if you reach it, your lender may require higher payments, a lump sum, or a switch to fixed. Your trigger rate is listed in your mortgage contract.
The Financial Consumer Agency of Canada explains that past the trigger rate, unpaid interest can build up and the amount you owe can grow, a situation called negative amortization. One quarter point will not push most borrowers there. It does narrow the cushion.
HELOC. A line of credit has no amortization schedule to absorb the change. A 25-basis-point rise adds about $10.42 a month in interest for every $50,000 drawn, so $100,000 outstanding costs about $20.83 more each month. Small per line, but it compounds across a household carrying a mortgage, a HELOC and a car loan at the same time.
Rising interest costs were already the fastest-growing line in household budgets before any hike, as covered in Household Mortgage Interest Costs Grew Fastest Since 2024 in Q2.
A common reaction to a likely hike is to lock in before the announcement. The logic sounds clean: convert to fixed while it is still cheap. The evidence does not support treating October 28 as that deadline.
Fixed mortgage rates, including the rates lenders offer when you convert a variable mortgage, are priced off Government of Canada bond yields, not off the Bank's announcement. Those yields started moving the moment the odds did. On October 19, the five-year yield rose 14 basis points in a single session, as The Globe and Mail reported. Lenders had already been raising fixed rates for weeks.
In other words, a hike that markets price at 80 to 87 per cent is largely baked into today's fixed rates. If the Bank hikes, fixed pricing may barely move on the day. If it holds, yields could ease. Neither outcome makes October 27 a cheaper day to convert than October 29 by default.
That does not make conversion a bad idea or a good one. It makes it a separate decision, driven by the bond market and your own tolerance for payment changes, rather than by the announcement clock. Most lenders allow a variable mortgage to be converted to a fixed term mid-term, but the eligible terms and the rate offered are set by each lender, and the conversion rate is not necessarily the best rate available in the market.
The bond-driven pricing behind this is laid out in Bond Yields Push Fixed Mortgage Rates Higher While Bank of Canada Holds at 2.25 Per Cent.
If you renew within 12 months, the more important question is the path, not one decision. Macquarie economist David Doyle, quoted by CBC News, expects 125 basis points of increases by the end of 2027. Others expect one move, or none this month. A renewal priced today reflects a market that already expects more than one hike over the next year, which is why comparing offers now is about knowing your options, not beating a single date.
None of this requires a decision this week. It requires knowing your numbers so that whatever the Bank does, you are reacting to your own statement rather than a headline.
Every variable or HELOC borrower:
Variable mortgage holders:
HELOC holders:
Renewing in the next 12 months:

The practical stance is simple. Treat a hike as likely enough to plan for, not certain enough to panic over. The households best placed on October 29 are the ones who already know which row of the table they are in.
