There has been no change in yield spreads over the past week or month, indicating stable borrowing costs for these loan categories. For members considering refinancing, the consistent rate environment supports predictable budgeting, especially for those prioritizing fixed payments. First-time refinancers may find the 15-Year Fixed option advantageous due to its lower rate and shorter term, potentially reducing total interest expense.

Given the unchanged rates, members should evaluate their mortgage strategy carefully; consider fixed-rate options if stability is a priority and assess refinancing feasibility if projected savings exceed associated costs.

CONNEXUS CREDIT UNION

As of May 22, 2026, refinance fixed-rate mortgages show notable rate adjustments.

Conversely, the 30-year fixed refinance rate rose by 12.5 basis points in the last week to 6.75%, marking a 37.5 basis point increase over the past month; this reflects higher yield spreads impacting long-term borrowing costs.
Members considering refinancing should weigh these upward trends against potential savings, especially if locking in a fixed rate aligns with their financial strategy. Evaluating mortgage duration and cost implications is critical when interest rates shift. Consider refinancing if projected savings from lower principal or term adjustments exceed transaction costs.

DELTA COMMUNITY CREDIT UNION

As of May 22, 2026, refinance fixed-rate mortgages show a modest upward trend in borrowing costs. The 15-year fixed refinance rate stands at 5.125%, up by 12.5 basis points compared to one week ago and also 12.5 basis points higher than 30 days prior. Similarly, the 30-year fixed refinance rate is at 6.00%, reflecting an increase of 12.5 basis points over the past week and a more notable rise of 25 basis points month-over-month.
These incremental rate increases raise the cost of borrowing for homeowners considering refinancing, potentially affecting monthly payments and long-term interest expenses. Members aiming for predictable payments might prioritize the 15-year fixed option, which currently offers the lowest rates among today's refinance programs. Evaluating these shifts is critical for those balancing short-term affordability with long-term savings.
Members should analyze their current mortgage terms against these evolving rates to determine if refinancing can yield meaningful financial benefits despite recent rate upticks. Consider fixed-rate options if payment stability is a priority or assess refinancing opportunities when potential savings surpass associated costs.

Conversely, the 30-year fixed refinance rate increased by 25 basis points week-over-week to 6.5%, matching its level from 30 days ago; this uptick raises yield spreads and may impact long-term affordability for homeowners locking in extended terms.
Members considering refinancing should weigh the trade-off between the stable, lower-rate 15-year fixed option and the higher but longer-term 30-year fixed loan. Evaluating your mortgage strategy with current rates in mind can help optimize cost savings; for example, refinancing might be prudent if projected interest savings exceed associated fees.

That makes locking in today’s lowest 15-year fixed refinance at 5.125% from Delta Community an appealing option for many homeowners seeking shorter-term savings. If you prefer longer terms or jumbo loans, keep an eye on national averages and your credit union offers since they vary but remain competitive. Above all, weigh your personal financial goals and consider how small changes in rates affect your budget before deciding. Thoughtful timing and clear understanding will help turn market fluctuations into opportunities rather than obstacles.
