The war in the Middle East and Iran’s subsequent weaponization of geography has upended the Canadian interest rate landscape for April.
While domestic savings account rates and guaranteed investment certificate rates remain surprisingly resilient, the “energy tax” from the effective closure of the Strait of Hormuz is forcing a radical re-evaluation of the Bank of Canada’s next moves.
Just weeks ago, the consensus for Canadian interest rates was one of predictable stability. Market data from late February indicated that the BoC would maintain its policy rate at 2.25 per cent well into 2027. Savers and markets were expecting a long-term hold.
That calm has been shattered. The Strait of Hormuz, a chokepoint responsible for over 20 per cent of global oil shipments, has effectively been closed to tanker traffic – a shock the International Energy Agency has described as the largest such disruption in decades.
The resulting supply shock has sent oil prices soaring, creating a “cost-push” inflation spike that makes the BoC’s previous path of stability look increasingly untenable.
Rates update: Most tiers hold steady
Despite the chaos, the majority of savings and GIC rates have remained unchanged over the past month. The most competitive offers are still found in promotional savings accounts and short-term GICs.
Savings leaders: Bank of Nova Scotia continues to lead the market with a 4.65 per cent promotional rate for three months. However, savers should note this is a temporary offer – Scotiabank’s standard savings rate remains at just 0.4 per cent. For non-promotional funds, Saven Financial at 2.85 per cent and Oaken Financial at 2.80 per cent remain the top choices.
GIC shifts: The only notable movement over the past month has occurred in the three-year and five-year GIC categories. The best three-year GIC has climbed slightly to 3.77 per cent, while the five-year GIC climbed to 3.89 per cent. Both are from HomeEquity Bank.
The “savings arbitrage”: If you get the lowest mortgage rate and earn the highest promotional interest rate, liquid savings are out-earning debt. With variable mortgage rates now as low as 3.3 per cent to 3.4 per cent, homeowners can technically earn a higher return in a top-tier savings account – at 4.65 per cent – than they save by paying down their mortgage principal. Note that this arbitrage is temporary and depends on promotional rates, tax treatment and household risk tolerance.
The “Hormuz factor”
The current crisis is exacerbated by a perceived lack of leadership in Washington. While the Trump administration escalated the conflict, it appears to lack a plan for reopening the Strait of Hormuz, expecting other countries to handle the dangerous task.
This uncertainty is feeding directly into Canadian yields. Although the BoC is still most likely to hold at 2.25 per cent in April, the market has pivoted toward anticipating rate hikes by the year’s end. While the central bank typically looks through short‑term energy shocks, a sustained oil‑driven inflation spike would complicate its ability to stay on hold. Forward contracts now price in an 80-per-cent likelihood that the policy rate will reach 2.75 per cent by December, 2026.
