Soaring U.S. national debt, a prolonged Middle East conflict and inflation worries are combining to shake bond markets around the world. As a result, the Canadian 5-year bond yield is nearing a 12-month high, and major lenders are raising fixed mortgage rates across the board.

Key Points

• Canadian 5-year bond yield at 3.36% — up 0.08 percentage points from the previous week, just 0.03 percentage points shy of a 12-month high
• Major lenders raise 3- to 5-year fixed mortgage rates by 0.10–0.15 percentage points — some by as much as 0.20 percentage points
• U.S. national debt surpasses US$40 trillion — about $3 billion in interest per day (about $100 billion per month)
• U.S. 30-year Treasury yield at 5.337% — the highest since 2007
• U.S. Treasury attempts to expand bond buybacks from $2 billion → $4 billion — the stabilizing effect on the market proves short-lived
• Iran ceasefire agreement expires + further negotiations stall → tensions in the Strait of Hormuz + rising oil prices → ongoing inflation concerns
• Variable-rate discounts are holding for now — still a comfortable margin compared with fixed rates
• BoC neutral rate estimate range of 2.25–2.75% — with the current policy rate at 2.25%, there is room for further hikes

What It Means

This rise in fixed rates is significant because it is happening independently of BoC decisions. It shows once again that when the bond market moves, fixed mortgage rates can rise even if the BoC holds rates. If you can find a fixed rate of 3.99% or lower in the market right now, it is time to consider it seriously. Variable rates are relatively stable for now, as a near-term BoC hike is unlikely, but it is hard to completely rule out further hikes from 2027 onward. In the end, today's choice comes down to short-term stability (variable) versus medium-term certainty (fixed). Since the situation in the Middle East and U.S. fiscal conditions are unlikely to be resolved quickly, it is hard to rule out that fixed rates will face further upward pressure for some time. If you have a mortgage renewal or a new purchase coming up, now is the time to look at and think through fixed mortgage options as well.
