Joint Tightening Warning from North America's Central Banks: The Shockwave from the Fed's Rate Hike and the BoC Minutes

On Wednesday, the U.S. Federal Reserve (Fed) delivered a surprise policy rate hike and left the door open to further increases. On the same day, the Bank of Canada (BoC) released the minutes of its monetary policy meeting, formally stating that it is prepared to make "multiple hikes" if the surge in oil prices spills over into broader inflation. With the shock of a strong U.S. dollar colliding with Canada's energy-driven inflation fears, expectations of rate relief in North American financial markets have completely evaporated, and upside risk in the mortgage market has reached its peak.

Key Points

• The Fed's surprise rate hike and hawkish turn: Fed Chair Kevin Warsh announced a policy rate hike to rein in persistent inflation pressure and massive infrastructure investment demand, and clearly signalled a path of further increases.
• Warning in the Bank of Canada minutes (ready for multiple hikes): The BoC held its policy rate at 2.25% at its September 2 meeting, but the minutes released on the 16th stated that it is ready to carry out "several consecutive rate hikes" to stop high oil prices from the Iran war from spreading to the prices of other goods and services.
• An "import price crisis" driven by King Dollar and a weak loonie: The Fed's surprise hike widened the interest rate spread between the two countries and sent the U.S. dollar soaring. The weakened Canadian dollar (CAD), combined with international oil prices above $100 per barrel, has maximized imported inflation pressure at home.
• Limits to offsetting the trade slowdown (Growth Drag): BoC members narrowly held rates in September out of concern about the economic slowdown from the tariff war with the U.S., but made it firmly clear that if broad price instability is confirmed, they will put price stability ahead of economic weakness.
• Odds of an October BoC hike jump to 60%: With the Fed's hike and the BoC's ultra-hawkish minutes combined, the bond market has raised the probability of a surprise policy rate hike at the BoC meeting at the end of October to 60%.

What It Means

Today's events show that the North American monetary policy landscape has turned fully toward tightening. With the U.S. dollar surging after the Fed's hike, if the Bank of Canada keeps holding rates it will face a further plunge in the Canadian dollar and "uncontrollable imported inflation" from high oil prices. In the end, the "multiple-hike warning" spelled out in the BoC minutes suggests the BoC will have no choice but to join the rate-hike line soon, if only to narrow the rate gap with the Fed and defend the currency.

For mortgage market participants, this means a "double burden" is becoming reality.

Variable rate: With expectations of a Canadian policy rate hold collapsing, borrowers are directly exposed to the risk of a higher prime rate and larger monthly payments from additional rate hikes as early as October (current probability 60%).

Fixed rate: With U.S. Treasury yields staying high on the Fed's hawkish moves, and the possibility of the BoC shifting to tightening added on top, the Government of Canada 5-year bond yield (GoC 5Y) has become even more resistant to falling.

This is no longer a time to discuss "when will rates come down," but a phase in which households must prepare for "how to withstand the shock of further rate hikes." If you have a mortgage renewal coming up or are planning new financing, we recommend securing a 3–4 month rate hold to get ahead of upside risk, and then re-checking your household's payment capacity very conservatively.
