Your U.S. Dollar ETF Adds a Second Risk to Your Canadian Mortgage
The advice usually arrives secondhand, from a peer who means well. A borrower who bills U.S. clients is uneasy about where Canadian mortgage rates will sit at renewal, and someone suggests parking the American income in a .U ETF on the TSX. Keep it in U.S. dollars, skip the conversion, and you'll have a cushion if borrowing costs climb. It sounds prudent. The trouble shows up later, when a payment or renewal is coming and nobody can say how many Canadian dollars that cushion will actually produce.
The pattern is common among Ontario business owners, consultants and self-employed investors whose income and savings move between two currencies while the mortgage stays firmly in one. If that's your situation, the question worth settling is simple: is the money you've set aside for housing dependable in the currency your lender accepts? An asset is not a reliable hedge just because it might rise when your costs rise. It has to reliably offset the particular risk you need covered, and a pile of U.S. dollars doesn't reliably offset a Canadian interest rate.
Why the U.S. dollar may not rise when your mortgage costs do
The .U label tells you the fund trades in U.S. dollars. It doesn't tell you what currency exposure you actually own. That depends on the underlying holdings and whether the fund hedges its currency, so read the fund's documents before assuming anything. Where the exposure is unhedged U.S. dollars, you've added a second moving number to your housing budget: the exchange rate now sits alongside your mortgage rate.
The two numbers answer to different forces. Canadian variable rates follow the Bank of Canada's overnight rate, and fixed rates reflect bond yields and lender pricing. The U.S. dollar responds to U.S. Treasury yields, global risk appetite and much else. The two central banks don't always move together. On June 5, 2024, the Bank of Canada cut its policy rate, and the Federal Reserve held its own that month. A gap like that is one influence among many on the exchange rate, never a formula. That's the point: nothing ties your U.S. savings to rise in Canadian terms at the moment your mortgage gets more expensive. If Canadian rates climb and the loonie strengthens at the same time, those savings buy fewer Canadian dollars exactly when you need more.
Protect the payments instead of betting on an offset
Run the uncomfortable version on paper. Suppose your mortgage costs rise and, in the same stretch, a stronger Canadian dollar trims the Canadian value of U.S. savings that haven't changed by a cent. If that combination strains your budget, your U.S. holdings were never dependable mortgage protection. They were an investment you were hoping would cooperate.
What you face depends on the mortgage itself. With a variable rate, the contract decides whether a rate increase raises your payment or stretches the amortization. With a fixed rate, the exposure lands at renewal, so the money that matters is what you'll need in that window. Either way, keeping the next stretch of payments in Canadian dollars removes the conversion guesswork. It won't stop rates from rising, but it means you're only watching one number.
The same discipline applies before a renewal or refinance. Ask your lender how it assesses foreign income and which records it wants. For self-employed borrowers that usually means two years of history, and CMHC looks for 24 consecutive months. A switch to a new lender or a refinance on an uninsured mortgage means qualifying at the higher of your contract rate plus 2% or 5.25%, under OSFI's rule. An ETF balance can show you have savings. Your lender still decides whether your income covers the payment.
None of this makes U.S. dollar investments a mistake. A global portfolio can earn its place for long-term reasons. The error is assigning it a job it can't reliably perform. Start with your next twelve months of mortgage payments. Mark which ones currently depend on converting U.S. dollars, then value that money in Canadian dollars at a rate you'd be unhappy to accept. That figure is the protection you actually have.
