Treasury Yields Extend Higher, Signaling Continued Headwinds for Mortgage Rates
Treasury yields pushed higher again on Friday, with the 10-year crossing 5.00% by the close, reflecting persistent market concerns about inflation and the Federal Reserve's 'higher for longer' stance. While today is quiet on the data front, the upward pressure on rates is expected to continue, challenging mortgage rate improvement.
Vabasso Rate Outlook
Today's Mortgage Market
Mortgage rates are under renewed upward pressure following Friday's increase in Treasury yields. The 30-year fixed rate Freddie Mac PMMS, last reported at 6.95% for the week ending September 17th, does not reflect this latest move, but the underlying Treasury market dynamics suggest rates moved higher into the weekend and are likely to open Monday session similarly elevated. The primary mortgage/Treasury spread remains wide at 201 basis points, indicating that even if Treasury yields stabilize, mortgage rates may not improve proportionally.
MBS
Licensed current MBS pricing data is unavailable. Therefore, our analysis of mortgage-backed securities must rely on the movement in the Treasury market and the derived primary mortgage/Treasury spread. Given the significant increase in Treasury yields, particularly the 10-year, MBS valuations are presumed to have deteriorated commensurate with the broader fixed-income market's repricing. The wide spread continues to reflect reduced investor appetite for mortgage credit risk and prepayment uncertainty, limiting the upside for mortgage rates even if Treasury yields were to consolidate.
Treasuries
Treasury yields moved notably higher on Friday, with the 10-year Treasury closing at 5.01%, up 7 basis points for the day. The 2-year yield rose 9 bps to 4.76%, and the 5-year yield increased 8 bps to 4.86%. The 30-year yield also climbed 5 bps to 5.34%. This broad-based increase across the curve reflects a market grappling with robust economic data, elevated oil prices, and the implication for Federal Reserve policy. The 2s10s spread widened slightly to 25 bps, still reflecting a flattened, but less inverted, curve dynamic.
The Economy
While there were no high-impact economic releases on Friday, market participants continued to digest recent data pointing to a resilient economy, particularly in the labor market. This resilience, combined with rising energy prices (WTI Crude closed at 107.02 last week), fuels concerns that inflation may remain stickier than anticipated, forcing the Federal Reserve to maintain higher interest rates for longer. This narrative heavily influences the current bond market sentiment.
What Matters Today
Today is exceptionally quiet on the economic calendar, with no scheduled high-impact releases. Market focus will be on assessing the sustained upward momentum in Treasury yields from Friday and whether that trend continues into the new trading week. Without fresh economic data, technical trading and broader risk sentiment will likely drive market action. Investors will also be looking ahead to Wednesday's Initial Jobless Claims and Durable Goods orders, as well as the higher impact data later this month.
What Mortgage Professionals Should Know
Mortgage professionals should communicate an elevated risk of higher rates to borrowers, especially given the breach of the 5.00% level on the 10-year Treasury. While today is quiet, the underlying market dynamics are not favorable for rate improvement. Prudent pipeline management requires anticipating continued upward pressure and preparing clients for a potentially more challenging rate environment through the end of the month and into October, particularly if key inflation and employment data support the 'higher for longer' narrative. Monitor Treasury yields closely as the primary indicator for mortgage rate direction.
