War Premium Drives Mortgage Rates to October Highs

Mortgage rates are trending higher this week. The MBA reported the contract rate on a 30-year fixed loan reached 6.43% for the week ended March 20 — the highest level since last October. The 10-year Treasury, which closely tracks mortgage pricing, spiked to 4.39% last Friday before settling back to 4.34% by Monday. Freddie Mac's weekly PMMS survey, which lags slightly, showed 6.22% through March 19 — but the market has moved since then.

Two forces are driving the move. The conflict in the Middle East pushed oil prices past $100 per barrel last week, reigniting inflation concerns in the bond market. Higher oil flows into transportation, manufacturing, and eventually consumer prices — and bond investors are pricing that risk in now, not later. At the same time, the Federal Reserve held rates steady at 3.50–3.75% at its March 18 meeting but revised its inflation forecast upward: the Fed now expects headline and core PCE to run at 2.7% through 2026, up from December's projections of 2.4% and 2.5% respectively. A Fed that's cautious on cuts, combined with geopolitical-driven inflation risk, has given bond sellers the upper hand.

For rate shoppers, the important thing is the direction and its cause. Rates are trending higher because inflation expectations are moving higher — not because the economy is booming. That's a different environment than we've been in. If you're evaluating a purchase, the breakeven question still applies: how long does the loan need to work for the cost to make sense at current rates? Run that math at current pricing using the rate tool, then revisit if conditions change. What to avoid is making the timing call based on a prediction. Nobody called the oil shock. Nobody called the yield spike. Price the loan you have today against the scenario you're actually in.

Friday's February PCE report — the Fed's preferred inflation gauge — is the main event this week. If it prints above the Fed's 2.7% revised projection, expect another leg higher in yields. If it comes in soft, we may see a small pullback. Either way, the current trading range on the 10-year (4.30–4.40%) looks like the floor for now, not the ceiling.
