High Mortgage Rates Persist at 6.48%

The U.S. housing market continues to grapple with high mortgage rates, which have remained above 6% and are currently averaging 6.48%, according to data released on June 4, 2026, by Freddie Mac. This marks a significant increase from February 2026 when rates had dropped as low as 6%. The persistent high rates have weighed heavily on potential homebuyers and those seeking to refinance their mortgages.

President Donald Trump has been vocal in his pressure on the Federal Reserve to implement deeper rate cuts, aiming to lower borrowing costs. New Fed chief Kevin Warsh has also indicated support for rate cuts since his nomination by Trump, a shift from his previous anti-inflation stance.

However, experts argue that the Federal Reserve's control over mortgage rates is limited. The central bank primarily influences the federal funds rate, which affects short-term borrowing costs rather than long-term mortgages. Thirty-year mortgages are influenced more by financial markets and investor expectations regarding inflation, economic growth, government borrowing, and future interest rates.

Inflation, in particular, is a significant factor driving mortgage rates. Despite declining from the peaks of 2022 and 2023, investors remain uncertain about when inflation will return to the Fed's target of 2%. Elevated oil prices and ongoing conflicts contribute to this uncertainty. Additionally, government borrowing plays a crucial role; the Congressional Budget Office estimates that Trump's tax and immigration bill passed in 2025 will add $US3.4 trillion to federal deficits through 2034.

The complexity of mortgage-backed securities further complicates the situation. Investors demand higher yields to compensate for risks such as prepayment, which can occur if homeowners refinance or sell their properties. This has kept the spread between Treasury yields and mortgage rates elevated compared to historical norms.

Meanwhile, the U.S. Treasury is issuing more than half a trillion dollars of T-bills per week on average, according to Reuters. While this spike in short-term financing is not currently problematic, it could become an issue if borrowing costs rise further. The Trump administration's reliance on shorter-term borrowing is driven by persistently wide budget deficits and elevated inflation, which has pushed up the term premium.

The federal interest bill is already on track to top $1 trillion this fiscal year, with cumulative interest costs for the first four months of 2026 reaching $616 billion. This figure represents a significant increase from previous years and underscores the growing burden of debt servicing. The Treasury's current share of bills in the total outstanding federal debt stock stands at just under 22%, slightly below the historical average but above recommended levels.

Analysts warn that as the share of bills approaches 25% of an expanding net borrowing need, the Treasury will have to look harder at potential sources of demand. This situation could become particularly challenging if there is a recession or economic slowdown, which would likely increase bill issuance and debt service costs.
