Why Treasury Yields and Mortgage Rates Are Rising

Mortgage Servicing Rights (MSR) valuations and mortgage rates increased in July 2026 as Treasury yields rose in response to stronger-than-expected economic data and persistent inflation concerns, according to a market update from Mortgage Capital Trading (MCT).

The rise in yields was further driven by geopolitical tensions, which influenced the pricing of government securities and subsequent lending rates. These factors collectively pushed mortgage rates higher, affecting the valuation of MSR portfolios.

Impact of Economic Data on Treasury Yields

Treasury yields climbed throughout July 2026 after the release of economic indicators that exceeded analyst expectations. According to MCT, this data reinforced concerns that inflation remains a persistent issue, prompting a market adjustment in the cost of borrowing.

The correlation between Treasury yields and mortgage rates means that as the yield on government bonds rises, lenders typically increase the interest rates charged on home loans to maintain profit margins. This upward movement in rates generally increases the value of existing MSR portfolios because the higher-rate environment discourages homeowners from refinancing their current loans.

MSR Valuation and Refinancing Trends

Mortgage Servicing Rights are financial assets that represent the right to service a mortgage loan. Their value is heavily tied to the “prepayment speed,” or the rate at which borrowers pay off their loans early through refinancing or home sales.

When mortgage rates rise, as they did in July 2026, the incentive for borrowers to refinance disappears. This slows the prepayment speed and extends the expected life of the MSR asset, which typically leads to an increase in the asset’s market value. MCT reports that the combination of inflation fears and geopolitical instability contributed to this environment.

Geopolitical Influence on Market Rates

Beyond domestic economic data, MCT identified geopolitical tensions as a primary driver that pushed Treasury yields and mortgage rates upward during the July 2026 period. Global instability often leads to volatility in the bond market, affecting how investors price risk and yield.

The interaction of these three factors—economic data, inflation, and geopolitics—created a compounding effect on the mortgage market. While stronger economic data suggests growth, the accompanying inflation concerns and global tensions create a higher-rate environment that benefits the holders of MSRs by locking in borrowers at their current rates.
