“Mortgage rate is the rate of interest charged to a borrower on a mortgage.”[1]

A mortgage rate is the interest a household pays on a home loan. In the US it usually tracks the 10-year Treasury yield plus a spread, because most mortgages are paid off or refinanced long before thirty years pass.
房贷利率是家庭为购房贷款支付的利息。在美国，它通常跟随 10 年期国债收益率加一段利差，因为大多数房贷在三十年到期前就被还清或再融资。
The mortgage rate is the most politically visible interest rate in America. A move from 3% to 7% on a $400,000 loan adds roughly $1,000 a month, which locks existing owners into their old loans and freezes the market. That is why home sales can collapse while prices stay high: it is a standoff, not a crash.
房贷利率是美国政治敏感度最高的利率。40 万美元贷款，利率从 3% 到 7%，月供多出约 1,000 美元。
这会把现有业主锁在旧贷款里，让市场冻住。所以成交量可以崩，价格却不跌——那是僵持，不是崩盘。
| Move变动 | Where it appeared出现位置 | What it means这句话在说什么 |
|---|---|---|
| 7.5% | Why a $2 trillion deficit and 5% Treasury yields are becoming America’s biggest economic challenge 房贷利率 —— 家庭为购房贷款支付的利率。因 · 第 4 张术语卡 | The average 30-year fixed rate is around 7.5%, and pending home sales fell 4% in September. 为什么房贷跟着 10 年期国债走：银行发放 30 年固定贷款后，通常把它打包成 MBS 卖给投资者，投资者要求的回报以国债收益率为基准。国债收益率每上行 100 个基点，30 年期房贷利率大致同向变动 80–100 个基点。 |
| 7.40% | US pending home sales fall to a 12-year low as mortgage rates top 7% 房贷利率 —— 家庭为购房贷款支付的利率。因 · 第 1 张术语卡 | The 30-year fixed rate reached 7.40% in the week to October 8, against 5.98% at the end of February. On a $400,000 home, that difference is about $376 a month. 看房贷利率要分清三层：① 政策利率（美联储的联邦基金利率）只决定短端资金价格；② 真正决定 30 年期房贷的是长期国债收益率，尤其是十年期，因为银行和投资者的资金成本锚在长端；③ 最上层的才是银行加给你的利差（信用、期限、服务费）。所以「美联储加息」只是间接影响房贷，真正的推手是长债收益率。这轮十年期美债收益率从战前的 3.97% 升到 10 月 8 日的 5.29%，房贷利率自然跟着跑到 7.4%。 |
Mortgage rates follow the Fed
They follow the 10-year yield, which anticipates the Fed.
A lower rate always boosts sales
Not if prices rose faster. Payment affordability is what matters.
30-year fixed means 30 years
The average mortgage is repaid or refinanced in under ten.
