In three weeks, rates went from 5.99% to 6.53% — the highest since last fall. The bond market closed down 31/32 today. The 10-year Treasury hit its highest yield since July. Here's the full picture.
Friday closed the worst week for mortgage rates since last fall. The Mortgage News Daily 30-year fixed rate index closed at 6.53% — up 10 basis points on the day, and up 54 basis points from where it stood on February 27th when rates were at 5.99%. MBS (mortgage-backed securities) closed down 31/32 today, a move that typically translates to a rate increase of roughly 0.375% compared to Thursday's pricing. The UMBS 30-year 5.0 coupon closed at 98.15, down 0.85 on the day. The 10-year Treasury yield hit 4.383% — its highest level since last July.

The driver is the same one that has been hammering bonds all month: the Iran war and its impact on oil prices and global inflation expectations. President Trump this week requested $200 billion in emergency war funding from Congress — a figure that, if approved, would require the Treasury to sell significantly more debt to finance it. More Treasury supply means lower bond prices and higher yields, which feeds directly into higher mortgage rates. Global central banks, including the European Central Bank, are also rapidly reassessing their rate-cut timelines as energy costs surge worldwide. This coordinated global hawkishness is amplifying the bond market selloff beyond what the US alone would produce. (Sources: Moving.com, Seeking Alpha, March 20, 2026)
There is no major economic data scheduled for next week, which means the bond market will be almost entirely driven by Iran war headlines and oil price movements. Fed officials will be making public appearances, but Chairman Powell's only scheduled remarks are a brief award acceptance that is expected to be a non-factor. The next significant data point is the PCE inflation report on April 9th — and given the hot PPI numbers from Wednesday, that report is expected to show accelerating inflation. Two shorter-term Treasury auctions are scheduled midweek but are unlikely to move rates significantly. In short: next week is a headline-driven market.

Here is the honest assessment: the path back to February's rates requires the Iran conflict to de-escalate and oil prices to fall. Without that, the inflation pressure on bonds remains, and rates are unlikely to recover meaningfully. Some respected analysts are warning that oil could go higher still before this is resolved. If you are closing in the next 60 days, locking now is the defensible call. If you are more than 60 days out, there is a case for floating — but you are accepting real risk that rates could move higher before they move lower.
