Understanding the Bank of Canada’s March 18, 2026 rate of interest decision

This signifies that the bank’s overnight rate of interest stays at 2.25%, while the important thing rate utilized by lenders, which can also be based on this benchmark, stays at 4.45%. This rate of interest serves as a price floor for a variety of variable rate loan products, including variable mortgage rates, HELOCs and certain sorts of loans. The rate of interest has now been at this level since October 2025, when the bank implemented the last of its nine series of rate cuts.

This latest rate hike comes as no surprise to market watchers; Canada’s sluggish labor market and overall weak economic performance in 2025 have given the bank little reason to take motion. The latest consumer price index report for February, released by StatCan on March 16, also indicates that inflation growth at 1.8% stays below the bank’s 2% goal – all of the more reason to keep on with rate of interest policy.

However, the bank faces recent geopolitical pressures that might influence rate of interest decisions within the near future; The ongoing war in Iran and the resulting high energy prices could fuel inflation back to dangerous levels. If this were to occur, it could potentially force the bank to lift rates again, even against a weak economic backdrop (also often called stagflation).

For now, nevertheless, the bank has made clear that it is just “too early” to estimate how the war will affect the Canadian economy and whether it’ll need to alter rates of interest in response. Policymakers have to see compelling evidence that higher inflation is going on – and can persist – before deciding to lift rates of interest.

“Against this general backdrop, the Governing Council has decided to keep the key interest rate at 2.25%. With recent data pointing to weaker economic activity and increased uncertainty, growth risks appear to be tilted to the downside. At the same time, inflation risks have increased due to higher energy prices.” says the bank’s press release accompanying the tariff announcement.

“We will continue to assess the impact of U.S. tariffs and trade policy uncertainty and examine how the Canadian economy adjusts. We are also closely monitoring the evolving conflict in the Middle East and assessing its impact on growth and inflation. As the outlook continues to evolve, we stand ready to respond as necessary.”

What the BoC rate of interest means for mortgage borrowers

Whenever the BoC makes a rate announcement, those that have already got variable rate mortgages are essentially the most affected as the value is predicated on a plus or minus percentage to the lender’s base rate. Since the bank maintained rates of interest in March, the rate of interest, the quantity of the payment and the a part of the payment that might be used to repay the principal debt is not going to change for these borrowers.

However, when you’re currently excited about taking out a variable rate mortgage, it might be a very good idea to submit your application sooner somewhat than later to make sure pre-approval and rate lock-in. While policy rates is not going to change until the BoC makes a move, lenders should adjust the spread they provide to match that policy rate, potentially reducing the savings passed on to the client. By securing a set rate of interest for as much as 120 days, access to today’s variable rates of interest is guaranteed, which is currently a low of three.35% for a term of 5 years.

Meanwhile, fixed-rate mortgage rates are under strong upward pressure. While fixed rates will not be directly influenced by BoC rate of interest movements, they’re based on bond yields. These have risen steadily since February as investors grow to be increasingly concerned about the potential for a protracted war resulting in higher inflation and better central bank rates of interest, each of which cause bond prices to depreciate. Investors selling bonds – driving up yields – has been a recurring occurrence since February, prompting some lenders to lift their fixed-rate mortgage rates.

Of course, when you’re already locked into a set rate of interest, this would possibly not affect you as fixed rates of interest won’t change throughout the lifetime of the mortgage. However, when you’re currently pursuing a set price or have a renewal coming up, the identical wisdom applies: securing that pre-approval now offers you more options within the event that fixed prices proceed to rise within the near future.

What the BoC rate means for Canadians’ savings

If a central bank keeps rates of interest on hold, it may possibly be good or bad news for mortgage holders, depending on their expectations; Those waiting for rate of interest cuts might be dissatisfied, while others may benefit from continued stability.

However, it’s fundamentally a positive development for savers and passive investors; Guaranteed Income Investments (GICs) and High Yield Savings Accounts (HISAs) are each based on prime lending rates, meaning their returns will rise and fall in accordance with central bank policy. This latest rate of interest increase means stability and security for savers because the rates of interest on their accounts and investments is not going to change in the intervening time.
