U.S. mortgage rates have experienced a significant increase, reaching levels not observed since August of the previous year, primarily driven by inflationary pressures and geopolitical conflict.

美國抵押貸款利率大幅上升，達到自去年八月以來未見的水平，主因是受通貨膨脹壓力與地緣政治衝突驅動。

The current trajectory of the U.S. housing market is characterized by a marked divergence from initial annual projections. While economists anticipated a robust spring season facilitated by lower borrowing costs and increased inventory, the commencement of hostilities in Iran in late February precipitated a systemic shock. This geopolitical instability has catalyzed a surge in oil prices and a subsequent escalation in inflation, which currently resides at its highest level in three years. Consequently, mortgage rates for 30-year fixed loans rose to 6.51 percent by May 21, with subsequent data indicating a further ascent to approximately 6.65 percent by May 25.

目前美國房屋市場的軌跡與最初的年度預測有顯著分歧。雖然經濟學家預期低借貸成本和庫存增加將帶來強勁的春季市場，但二月底伊朗爆發的敵對行動造成了系統性衝擊。這種地緣政治不穩定觸發了油價飆升以及隨後的通貨膨脹，目前通膨已處於三年來的最高水平。因此，30年期固定貸款的抵押貸款利率在5月21日升至6.51%，隨後的數據顯示至5月25日進一步上升至約6.65%。

From a structural perspective, the upward pressure on rates is attributed to the volatility of mortgage-backed securities and 10-year Treasury yields. Institutional analysis suggests that inflation-induced sell-offs in the bond market necessitate higher yields, which directly correlate with increased mortgage costs. Furthermore, the Federal Reserve's monetary policy remains restrictive; despite previous reductions, no cuts have been implemented in 2026, and there is a perceived 50 percent probability of a rate hike by year-end. This environment is further complicated by the erosion of real wages, which have transitioned into negative territory, thereby diminishing the purchasing power of lower-to-middle income cohorts.

從結構角度來看，利率的上升壓力歸因於抵押貸款擔保證券（MBS）與10年期國債收益率的波動。機構分析指出，通膨引起的債券市場拋售使得收益率必須提高，這與抵押貸款成本的增加直接相關。此外，聯準會的貨幣政策依然採取緊縮態度；儘管先前有所調降，但2026年尚未實施任何降息，且市場認為年底前有50%的機率會調高利率。實質薪金轉為負值進而削弱了中低收入群體的購買力，使環境更加複雜。

Despite these headwinds, a degree of market recalibration is evident. Stakeholders observe that prospective buyers are increasingly adapting to a 'higher for longer' interest rate paradigm, shifting away from the expectations of the pandemic-era lows. However, discretionary demand remains suppressed. Market analysts predict a summer characterized by hesitation, with anticipated price reductions in softening regional markets, particularly in the South and West, as inventory continues to accumulate due to stagnant demand.

儘管面臨這些不利因素，市場仍顯現出一定程度的重新校準。利害關係人觀察到，潛在買家正逐漸適應「高利率維持較長時間」的範式，不再期待疫情期間的低利率。然而，非必要需求依然受到抑制。市場分析師預測今年夏天將以猶豫為主，隨著需求停滯導致庫存持續增加，部分疲軟的區域市場（尤其是南部和西部）預計價格將會下調。

The U.S. housing market remains in a state of volatility, with future rate movements contingent upon the stabilization of the conflict in Iran and subsequent inflationary trends.

美國房屋市場仍處於波動狀態，未來的利率走勢將取決於伊朗衝突的穩定程度以及隨後的通膨趨勢。
