Yield Curve

Also known as: Treasury yield curve, normal yield curve, inverted yield curve

Definition

The yield curve plots U.S. Treasury interest rates across maturities from 3 months to 30 years. A normal (upward-sloping) curve means long rates exceed short rates. An inverted curve — where short rates exceed long rates — has historically preceded recessions and signals tighter lending conditions for businesses.

Detailed explanation

The yield curve is a snapshot of where Treasury yields stand across the maturity spectrum. The Federal Reserve publishes daily Treasury constant-maturity rates (the H.15 release) for maturities from 1 month to 30 years. The most-watched segment: the spread between the 2-year Treasury and the 10-year Treasury (2s10s spread).

Three shapes matter for business lending: 1. Normal (upward-sloping): Short rates < long rates. Lenders earn more on long-dated loans than short ones, incentivizing long-term credit extension. This is the typical backdrop for healthy small business credit markets. 2. Flat: Short and long rates converge. Lenders' net interest margins compress, often prompting tighter underwriting standards and higher spreads to borrowers. 3. Inverted: Short rates > long rates (2-year Treasury > 10-year Treasury). Historically a reliable recession leading indicator — the U.S. 2s10s spread inverted in 2006-07 (before the financial crisis) and in 2022-23 (before credit tightened sharply for SMBs in 2023). Inverted curves often coincide with banks pulling back on commercial lending.

For small business owners: an inverted yield curve may mean banks become harder to access, bank credit standards tighten (per the Fed Senior Loan Officer Opinion Survey), and alternative lenders fill the gap at higher rates. SBA 504 deals (which depend on long-dated debt markets) become more expensive as the debenture pricing moves with long rates. Understanding the yield curve helps business owners time refinancing and debt rollover decisions.

◈ Worked example

Normal curve: 3-month Treasury at 4.0%, 10-year at 5.5%, 30-year at 5.8% — long rates meaningfully above short rates
Inverted curve: 3-month at 5.3%, 10-year at 4.2%, 2-year at 4.9% — short rates exceed long rates, classic recession signal
Business owner timing SBA 504: rate locks when 10-year Treasury is at 4.0% rather than 4.5% saves ~$7,500/year on a $1.5M debenture

Common questions

The most-asked questions about Yield Curve — answered straightforwardly.

Does an inverted yield curve mean a recession is coming? +

An inverted yield curve (specifically, when the 2-year Treasury yield exceeds the 10-year Treasury yield) has preceded every U.S. recession since the 1970s, typically with a 12-24 month lag. It is not a perfect signal — there have been false positives — but it is one of the most watched leading indicators by economists and Fed policymakers. The Federal Reserve Bank of New York publishes a recession probability model based partly on the 3-month/10-year spread.

How does the yield curve affect business loan rates? +

Short-term business loans (lines of credit, MCAs) are priced off short-term benchmarks (prime rate, SOFR). Long-term fixed-rate business loans are priced off the 10-year Treasury. When the yield curve is normal, long-term loans offer good relative value because long rates are only moderately above short rates. When the curve inverts, short-term borrowing costs spike relative to long-term rates, sometimes making short-term credit lines more expensive than 10-year term loans.

Where can I see the current yield curve? +

The U.S. Treasury publishes daily yield curve data at https://home.treasury.gov/resource-center/data-chart-center/interest-rates/. The Federal Reserve H.15 release at https://www.federalreserve.gov/releases/h15/ also publishes daily constant-maturity Treasury rates across all tenors.
