U.S. Dollar Index (DXY) vs 15-Year Fixed Mortgage Rate

How These Two Indicators Relate

Dollar Index sits in the trade category and 15-Yr Mortgage sits in the rates category, so they describe different parts of the same economy. Watching them together provides cross-checks: a coordinated move in both directions confirms a regime shift, while a divergence often reveals which sector of the economy is leading or lagging.

Both readings are currently moving lower. Dollar Index has moved lower -0.10 since the prior release; 15-Yr Mortgage has moved lower -0.1%. When two related indicators decline together, the move usually reflects a real economic shift rather than measurement noise.

What U.S. Dollar Index (DXY) Measures

The U.S. Dollar Index measures the value of the U.S. dollar against a basket of major currencies (euro, yen, pound, Canadian dollar, Swedish krona, Swiss franc). It reflects the dollar's purchasing power in international markets.

The dollar has weakened to 103.0, down from a January peak of 109.4. A weaker dollar is mixed for U.S. businesses: it makes American exports more competitive abroad and boosts the dollar value of foreign earnings (positive for multinationals), but it increases the cost of imported goods and raw materials. For executives at companies with significant international revenue, dollar weakness is generally a tailwind for reported earnings.

Methodology: The DXY is a weighted geometric mean of the dollar's value against six currencies: Euro (57.6%), Japanese Yen (13.6%), British Pound (11.9%), Canadian Dollar (9.1%), Swedish Krona (4.2%), and Swiss Franc (3.6%). It was established in 1973 with a base of 100. The Federal Reserve also publishes broader trade-weighted dollar indices. Source: FRED at the St. Louis Fed (series DTWEXBGS).

What 15-Year Fixed Mortgage Rate Measures

The 15-year fixed mortgage rate is the average interest rate on a conventional 15-year home loan. It offers a lower rate than the 30-year fixed but with higher monthly payments due to the shorter repayment term. Sourced from Freddie Mac's weekly Primary Mortgage Market Survey.

At 5.89%, the 15-year fixed rate carries a roughly 0.75 percentage point discount to the 30-year rate. Borrowers choosing the 15-year term pay significantly less in total interest over the life of the loan — typically saving over $100,000 on a $400,000 mortgage. For financial advisors and wealth managers, the spread between 15-year and 30-year rates signals how the market prices term risk. A narrowing spread suggests lenders expect rates to decline.

Methodology: Freddie Mac surveys lenders weekly to compile the Primary Mortgage Market Survey. The 15-year rate reflects the average offered rate for a conforming 15-year fixed loan with 20% down payment to a borrower with strong credit. Actual rates vary based on creditworthiness, down payment, and loan size. Source: FRED at the St. Louis Fed (series MORTGAGE15US).

How These Comparisons Are Built

Each pairwise comparison page is statically generated from the live indicator dataset — values, trends, and source links are pre-rendered into HTML at build time. When the underlying dataset refreshes (each indicator on its own publication schedule), the comparison page regenerates automatically. ExecBolt does not estimate, model, or interpolate any reading; every value comes from the publishing agency’s primary release. For the full sourcing approach, citation format, and known limitations, see the methodology page.

For tools that translate macro readings into business outputs (DCF, runway, break-even), see the calculators page. Authoritative external context comes from the Federal Reserve’s FRED database, the U.S. Bureau of Labor Statistics, the U.S. Bureau of Economic Analysis, and the SEC EDGAR system.
