房利美周度指数：购房申请降1.4%，再融资申请升2.5%
房利美（Fannie Mae）公布的周度申请指数显示，截至2026年10月30日当周，购房申请水平指数（PALI）环比下降1.4%，再融资申请水平指数（RALI）则上升2.5%。一边降一边升，说明利率回落时先动起来的是再融资，购房需求还没有跟上。
再融资内部的差别更明显：只调整利率和期限的再融资申请当周升了9.4%，套现型再融资则原地不动，变动为零。换句话说，这一周新增的再融资意愿几乎全部来自想把利率降下来的借款人，而不是想从房子里套现金的人。
这两项指数每周二上午由房利美发布，数据来自其自动核保系统 Desktop Underwriter 经手的贷款申请，同时看申请笔数和未偿本金余额的变化。房利美提醒，指数反映的是申请量的变化方向，不报告申请的原始件数，不能用它反推当周到底有多少人提交了申请。
覆盖面是这套数据的底气。房利美引用《住房抵押贷款披露法》2018年至2024年的数据称，期间大多数贷款都用过 Desktop Underwriter 核保，它是当时使用最广的核保引擎，因此这套周度指数能较快反映全美房贷申请的冷热。（来源：房利美）
Fannie Mae Weekly Index: Purchase Applications Fall 1.4% While Refinance Applications Rise 2.5%
Purchase mortgage applications fell while refinance applications rose in the week ending October 30, 2026, according to Fannie Mae's weekly application indices. The Purchase Application-Level Index (PALI) decreased 1.4 percent from the prior week, while the Refinance Application-Level Index (RALI) increased 2.5 percent, a split that shows refinancing responding first as rates ease while purchase demand lags.
The split inside refinancing is sharper. Rate-term refinance applications jumped 9.4 percent in the week, while cash-out refinance applications were flat at 0 percent change. In other words, nearly all of the week's new refinance interest came from borrowers looking to lower their rate, not from owners pulling cash out of their homes.
Fannie Mae releases the two indices at 10:00 a.m. ET on Tuesdays, built from loan application data in its automated underwriting system, Desktop Underwriter, tracking changes in both application count and unpaid principal balance. The company cautions that the indices do not report the raw number of applications and cannot be used to determine how many applications were submitted.
The series rests on broad market coverage. Citing Home Mortgage Disclosure Act data from 2018 through 2024, Fannie Mae notes that a majority of loans used Desktop Underwriter in that period and that it was the most widely used underwriting engine, which makes the weekly indices a timely read on mortgage application activity nationwide.
