ABERDEEN PROVING GROUND FEDERAL CREDIT UNION

On March 19, 2026, Jumbo 15 Year Fixed and Jumbo 30 Year Fixed purchase mortgage rates increased by 12.5 basis points compared to last week, now at 5.625% and 6.125%, respectively. Over the past 30 days, these rates rose by 37.5 basis points, reflecting a tightening in yield spreads for jumbo loans. This upward movement raises the cost of borrowing for high-value property buyers considering jumbo mortgages. Borrowers prioritizing predictable payments might favor the fixed-rate structure despite higher costs; however, rising rates suggest evaluating refinancing options if current loans were secured at lower yields. For members with jumbo loan needs, closely monitoring rate trends is crucial to optimize financing strategies and manage long-term expenses effectively. Consider refinancing if potential savings outweigh associated costs.

Similarly, the 30-Year Fixed Purchase rate remains at 5.875%, with no movement in yield spreads during the same period.
For members prioritizing predictability and long-term budgeting, these stable fixed rates offer clarity in borrowing costs amid broader market fluctuations.
