- Fed announcements have the strongest impact on long-term rates and Canadian stock futures.
- BoC announcements move short-term Canadian rates and the CAD/USD much more strongly.
- BoC communications have “little effect” on U.S. interest rates, creating asymmetric spillovers.
- Exchange rate reactions are driven by shifts in the Canada–U.S. interest rate differential.
How Fed and Bank of Canada communications influence Canadian markets
Communications from central banks are one of the most scrutinized in financial markets, but a Bank of Canada staff paper finds that not all communications are equal. While the Federal Reserve is known as the most influential central bank in the world, the study shows that the Federal Reserve and the Bank of Canada do not influence North American markets in the same way.
Different effects across the yield curve
The two central banks influence different segments of the Canadian yield curve.
| Market Segment | Dominant Influence | Evidence |
|---|---|---|
| Short-Term Rates (e.g., BAX futures) | BoC | BoC rate announcements cause mean absolute moves of 5.19 bps vs 2.60 bps for FOMC. |
| Long-Term Rates (e.g., 10-year & 30-year GoC bonds) | Federal Reserve | FOMC impacts on 30-year yields are larger (2.50 pp vs 2.13 pp cumulative). |
pp = percentage point
Why long-term rates respond more to the Fed
Two drivers explain the stronger long-end reaction to the Fed:
- Global risk premia are highly sensitive to U.S. monetary policy.
U.S. term-premium shocks spill directly into Canadian yields. - The Fed is the anchor for global financial conditions.
Long-duration bond markets price U.S. macro signals first.
At the 10-year horizon, the contribution of term-premium changes nearly matches expectations for both central banks — but the Fed’s impact remains larger.
Why short-term rates respond more to the BoC
Short-term Canadian instruments reflect
- These contracts price BoC policy expectations directly.
- BoC target-factor shocks generate ~6 bps moves in the 1-quarter-ahead BAX contract.
- Canadian traders hedge short-term monetary expectations locally, not through U.S. instruments.
Domestic policy simply matters more at the short end of the curve.
Impact on Canadian equity markets
Fed dominance: The equity channel
The Fed drives Canadian equities more strongly than the BoC across all communication types:
| Communication Type | Fed Impact | BoC Impact |
|---|---|---|
| Policy rate announcements | 30.35 bps | 29.1 bps |
| Speeches | 34.97 bps | 25.45 bps |
| Press conferences | 35.33 bps | 29.21 bps |
Why?
- Canadian equity markets are highly exposed to global risk sentiment, which the Fed shapes more than the BoC.
- FOMC announcements signal U.S. growth, global liquidity, and risk appetite, all key drivers for the TSX.
Why BoC communications move the CAD/USD exchange rate more strongly
Asymmetric spillovers between the U.S. and Canada
A key finding of the research is the asymmetry:
- FOMC announcements significantly affect both U.S. and Canadian interest rates.
- BoC announcements have no significant effect on U.S. interest rates.
This asymmetry forces the FX market to do the adjustment.
Interest rate differential: The core mechanism
When the BoC surprises markets:
- Canadian rates move
- U.S. rates don’t
- The Canada–U.S. short-term spread shifts sharply.
Because exchange rates must reflect interest rate parity, the CAD/USD reacts more strongly:
- BoC rate announcements: ~33.66 bps average CAD/USD move
- FOMC rate announcements: ~20 bps move
Exchange rate adjustment mechanism
Since U.S. rates remain unchanged after a BoC shock, the FX market becomes the primary channel through which monetary divergence is priced.
Put simply:
If the U.S. doesn’t move, the CAD must.
Implications for investors
- Duration risk: Watch the Fed: long-term yields move with U.S. macro conditions.
- Front-end trades: Watch the BoC: short-term rates price domestic policy shifts.
- FX positioning: Expect larger CAD/USD moves from BoC surprises.
- Equities: The TSX reacts more to global liquidity (Fed) than domestic signals (BoC).
