Prime Rate

The Canada–US prime rate gap: the Bank of Canada front-ran the Fed

For most of the last two decades, Canadian and US prime rates have tracked each other closely, with Canada's usually a shade higher or lower depending on which central bank was moving first. That changed decisively in 2024–2025. The Bank of Canada began its easing cycle four months before the Fed and cut faster once it started, opening one of the widest Canada–US prime spreads of the post-1995 era.

For the mechanics of how prime is set — as a markup over the overnight policy rate — see the Prime Lending Rate indicator page. This page focuses on the gap between the two, why it opened, and what it means for borrowers.

The numbers, as of early 2026

• Canadian prime rate: roughly 4.45%, down from a cycle peak of 7.20% in August 2023. The Canadian prime low during the pandemic was 2.45% in April 2020.
• US prime rate: roughly 6.75%, down from a cycle peak of 8.50% in July 2023. The US prime low during the pandemic was 3.25% (April 2020 through early 2022).
• Spread: Canada–US prime is about −230 basis points (Canadian prime lower by 2.30 percentage points). That is near the extreme of the historical range.

The convention is important when reading the chart:

• In Canada, prime = Bank of Canada overnight rate + roughly 220 bps (currently 2.25% + 2.20% = 4.45%).
• In the US, prime = top of the federal funds target range + exactly 300 bps (currently 3.75% + 3.00% = 6.75%).

That 80 bp difference in bank markup means the two prime rates were never truly comparable on a like-for-like basis even before the 2024 divergence. What matters for borrowers is each country's prime relative to each country's policy stance, and the spread between them is a cleaner read on the true policy-rate divergence once you account for the fixed markup.

The 2024–2025 cut sequences

Bank of Canada: began cutting June 2024, with nine cuts by October 2025 totalling roughly −275 basis points. The pace accelerated in late 2024 with back-to-back 50 bp cuts as inflation fell below target and the Trump tariff risk emerged.

Federal Reserve: began cutting September 2024, with six cuts by December 2025 totalling roughly −175 basis points. The Fed paused in early 2025 before resuming cuts as labour-market data weakened in the second half of the year.

The end result: the Canadian prime rate has fallen about 100 basis points more than the US prime rate since the top of the cycle, even though both started their cuts within three months of each other. The Bank of Canada was more decisive, and the divergence in prime reflects that.

Why the Bank of Canada cut faster

Three reasons most analysts cite:

1. Rate sensitivity: Canadian households are materially more rate-sensitive than US households. The standard Canadian mortgage is either a variable-rate product (which repays immediately when prime moves) or a 5-year fixed renewed frequently, versus the 30-year fixed-rate mortgage that dominates the US market. When the Bank of Canada raises rates, the transmission to household budgets is fast and painful; when it cuts, relief is fast too. The Fed is working with much longer mortgage duration and a correspondingly slower transmission.

2. The mortgage renewal cliff: roughly 76% of Canadian mortgages are scheduled to renew by the end of 2026 at rates materially higher than their original contracts. CMHC delinquency data shows arrears still extremely low — around 0.22% — but the pipeline of renewals at higher payments is a significant downside risk to consumer spending. The Bank of Canada has been explicit that this is one reason it is moving faster than the Fed.

3. Tariff exposure: Canada's trade exposure to the US is roughly a quarter of GDP. US tariffs impose a direct demand shock on Canadian producers that is much larger in proportional terms than the equivalent shock on the US economy. Cutting rates is one of the few tools Canadian policymakers have to offset that.

Governor Tiff Macklem said in 2025 that the Bank was "not close to" the limit of how far it could diverge from the Fed without forcing a disorderly move in CAD. The historical maximum spread between BoC and Fed policy rates is about 250 basis points, set in the mid-1990s. The current spread — Canada roughly 150 bps below the Fed — is well inside that envelope.

What the bank economists are saying

Forecasts from the Big Six Canadian banks for end-2026 range from a Bank of Canada terminal rate of 2.00% (most forecasts) to 2.75% (Scotiabank, the hawkish outlier). The Fed's end-2026 terminal is widely expected to land in the 2.75–3.25% range, which would close roughly half of the current spread but not eliminate it.

Housing analysts tracking the mortgage renewal wave (including Ben Rabidoux at Edge Realty Analytics) have emphasized that the Bank of Canada's cuts are partly front-loaded specifically to smooth the 2025–2026 renewal cliff. The Fed has no equivalent domestic pressure.

What the gap means for borrowers

If you are a Canadian variable-rate mortgage holder, your effective rate is now roughly 230 basis points lower than an equivalent US borrower. On a $500,000 mortgage over 25 years that is about $1,100/month in reduced interest cost. That is the single biggest reason the Canadian consumer has not been more obviously stressed by the renewal cliff: the cuts arrived just in time.

If you are a Canadian business borrower, your cost of working capital on a prime-linked line of credit is similarly cheaper in absolute terms. Business insolvencies in Canada are elevated but have flattened since mid-2025, consistent with the easing cycle starting to work.

If you are a US business or household borrower, you are paying materially more for short-term credit right now than your Canadian counterpart, and US floating-rate corporate debt has been one of the pain points in the 2025 credit cycle.

What to watch in 2026

1. The pace of Fed cuts relative to the BoC. If the Fed catches up faster than expected, the Canadian advantage narrows and CAD should firm.
2. Canadian core CPI and wage growth. Both are running closer to 3% than 2% and could force the Bank of Canada to pause, stalling further divergence.
3. Mortgage renewal data. Watch CMHC delinquency, not just headline arrears — if delinquencies start climbing above 0.3%, the Bank of Canada has cover to cut further even if inflation is sticky.
4. Tariff evolution. A tariff de-escalation removes one of the main reasons for BoC to stay dovish and narrows the spread quickly.

The short version: the prime-rate gap between Canada and the US is not a statistical accident, it is a deliberate policy choice by the Bank of Canada to front-run mortgage renewals and cushion tariff exposure. For borrowers and savers on either side of the border it is worth understanding in detail — and it is the kind of divergence that closes, sometimes quickly, when the underlying conditions shift.
