Broad Money Supply (M2) Growth

The Canada–US M2 divergence

Canada and the United States ran fundamentally different monetary playbooks during and after the pandemic, and the M2 money supply growth series is where that difference is most visible. Reading the two lines side by side — rather than either one in isolation — is the fastest way to understand why Canadian and American inflation, rates, and currency behaviour have diverged in 2024–2026.

For the underlying definition and how each central bank constructs the series, see the M2 Money Supply Growth indicator page. This page is about the gap between the two countries.

The headline: two pandemics, two responses

In the aggregate series published by the Bank of Canada and the US Federal Reserve:

• United States M2 peaked at roughly 25.6% year-over-year in January 2021, the fastest money supply expansion in the post-war data.
• Canadian M2 peaked at about 16.3% year-over-year in June 2020, high by historical standards but roughly nine percentage points below the US print.
• By late 2025 both series have converged back into a 4–5% range, with Canada running modestly faster than the United States on the most recent observations.

That nine-point gap at the peak is not a statistical artifact. It reflects real differences in fiscal transfers, central-bank facilities, and bank reserve accumulation, and it is the single most important framing for everything that followed — inflation, rates, and the Canadian dollar.

Why the US print was so much larger

The US M2 explosion was mostly fiscal. Three rounds of CARES and ARPA direct payments — roughly $1,200, $600 and $1,400 per eligible adult — landed in checking and savings accounts, which is exactly what M2 captures. The Paycheck Protection Program pushed another wave of deposits into small business accounts. On top of that, the Fed stood up eight emergency facilities (Main Street, PMCCF, SMCCF, the Municipal Liquidity Facility, and others) and expanded its balance sheet from roughly $4 trillion to a peak above $9 trillion, with much of that creating new commercial-bank reserves.

Canada's fiscal response was smaller in aggregate and narrower in design. The Canada Emergency Response Benefit paid $2,000 per month, but only to workers who had actually lost income — a much smaller eligible population than the US universal cheques. The Canada Emergency Wage Subsidy flowed through employers rather than into household deposit accounts directly. The Bank of Canada ran a handful of targeted facilities, but nothing approaching the size or scope of the Fed's 2020 alphabet soup.

The result: American households entered 2021 with materially larger excess deposit balances than Canadian households, relative to the size of each economy.

The inflation pass-through: not as asymmetric as you'd think

With US M2 growing almost 10 percentage points faster at the peak, you might expect US CPI to overshoot Canadian CPI by a similar amount. It didn't.

• US headline CPI peaked at 9.1% in June 2022.
• Canadian headline CPI peaked at 8.1% in the same month.

One percentage point, not nine. The rest of the US excess money supply absorbed into elevated savings, asset prices (housing and equities), and a delayed services-inflation wave that is still unwinding in 2026. Canadian inflation returned to the 1–3% target band earlier, briefly touched 1.6% in mid-2024, and has crept back above 2% since September 2025 — a reminder that the divergence is narrowing, not finished.

The QT exit: Canada went first, the Fed was forced out

The most important recent chapter in the M2 story is quantitative tightening. Here the two central banks made very different choices.

• Bank of Canada: announced the end of QT on January 29, 2025, following a telegraphed glide path laid out by Deputy Governor Toni Gravelle in late 2024. The transition was gradual and orderly. BoC settlement balances stabilized near the target range through 2025.
• Federal Reserve: held QT through most of 2025, despite growing repo-market stress. The FOMC announced the end of balance-sheet runoff on December 1, 2025 — and then on December 12, 2025 unveiled "reserve management purchases" of roughly $40 billion per month to stabilize funding markets.

Analysts including Lyn Alden and Joseph Wang have argued the December 2025 reserve-management purchases are effectively soft or "stealth" QE, even as the Fed insists they are purely technical. Canadian and US M2 growth have both picked up modestly since, with the US re-acceleration slightly larger on the most recent data.

The FX paradox

Surface reading: if the Bank of Canada is less dovish on money growth and has a lower policy rate than the Fed, the Canadian dollar should weaken. And it has — CAD traded in the 1.38–1.42 range against USD through most of 2025.

The twist: Bank of Canada research suggests only about 1 percentage point of recent CAD weakness is attributable to the Canada–US rate differential. The larger share is a tariff risk premium tied to Trump administration trade policy and a deterioration in Canada's terms of trade. In other words, the M2 and rate gap matter, but they aren't the dominant driver of the currency in 2025–2026.

A methodology warning you should not skip

Fed M2 and Bank of Canada M2 are not constructed the same way. The US definition includes retail money-market funds; the Canadian M2 series does not. The Bank of Canada also publishes a broader aggregate called M2++, which adds individual-held money market mutual funds, non-money-market CSBs, and some other near-money instruments. M2++ is the closer analog to US M2 for cross-country comparison.

The chart at the top of this page uses each country's headline M2 as reported by its central bank, which is the most common convention in financial media and academic work, but the 2020–2021 peak gap would narrow by a couple of percentage points if you used M2++ on the Canadian side. Treat the direction and timing of the divergence as reliable, and treat the exact peak-vs-peak magnitude as approximate.

What to watch in 2026

1. Whether the Fed's "reserve management purchases" expand or stabilize — a permanent regime of $40B/month is materially different from a temporary fix.
2. Canadian wage growth and core CPI, which are both running hotter than headline and keep the Bank of Canada from cutting aggressively.
3. Any tariff-driven shock to Canadian terms of trade, which feeds straight into CAD and, indirectly, into imported-goods inflation.
4. The gap itself: a re-widening in 2026 would signal the Fed is running looser than the BoC again, which has historically preceded another round of CAD weakness.

The short version: the US M2 line tells you about 2020–2021 fiscal policy and the 2025 repo-market accident. The Canadian M2 line tells you about a smaller, more conventional response and an earlier exit from QT. Watching them in parallel is how you read where the inflation and currency stories go next.
