Treasury Yields Topped 5% as Markets Locked In a December Fed Hike

The 10-year Treasury yield closed at 5.10% on November 12, according to Treasury data. Three days earlier, on November 9, it stood at 4.88%.

Over the same stretch the two-year yield climbed from 4.56% to 4.86%. Only two trading days separate the readings, because the bond market was closed on November 11 for Veterans Day.

In those two sessions the market came to treat a December Fed hike as close to certain. It looked like a bond story, but it reached every corner of the stock market.

Inflation Beat Forecasts for a Third Time

The spark was October CPI, released on November 10. Saxo reported that headline prices rose 0.4% on the month against a 0.3% forecast.

Core inflation, which excludes food and energy, rose 0.3% against a 0.2% forecast. It was the third straight 0.3% month and the third straight upside surprise.

Fed Governor Christopher Waller had set the bar in London before the data. He said a 50 basis point December hike should be considered if core CPI came in at 0.3% or higher.

The two-year yield jumped 17 basis points that day. Citing Treasury data, 24/7 Wall St said it was the largest one-day rise since April 2025.

The Two-Year Yield Reads the Fed's Path

The move can be read as a bond selloff. In fact, the market was rewriting the Fed's calendar.

A two-year note works like a bet on the average policy rate over the next two years. That is why it moves first and fastest when Fed expectations shift.

When the short end rises faster than the long end, it is called a bear flattening. The gap between two-year and 10-year yields narrowed from 32 to 24 basis points in two sessions.

The bars shrink as maturities lengthen for a reason. The long end prices growth and inflation, while the short end prices the Fed directly. More: The Yield Curve.

Small Caps Carried the Load in Stocks

According to market recaps, the S&P 500 ended November 12 down 0.35%. The small-cap Russell 2000 fell 1.66%.

Energy was the only S&P 500 sector to rise that day, up 1.51%. Brent crude gained 3.3% to $95.82, which recaps tied to news on Iran and the Strait of Hormuz.

Smaller companies tend to carry shorter-term and often floating-rate debt. When the short end rises, their interest bills climb before those of large companies.

The simplest way to track small caps' sensitivity to rates is the IWM fund, which follows the Russell 2000.

The Brake Inside the Fed

Hike expectations are strong, but there is no such unity behind a 50 basis point step. Cleveland Fed President Beth Hammack, who dissented for a hike in October, sounded more measured on November 12.

ActionForex reported that Hammack favored more frequent but smaller hikes. "I don't think we're behind the curve today."

According to Saxo, futures fully priced a quarter-point December hike after the CPI data. The probability of a 50 basis point move stayed near 9%.

The two-year yield is still below its 2026 high of 4.92%, set on September 28. The market sees a December hike as certain, but it has not yet bought a faster path.

What It Means for Investors

• The market has priced a quarter-point December hike, but only partly priced a 50 basis point step or a second hike in early 2027.
• Small companies reliant on short-term debt and richly valued stocks priced on distant profits remain the most rate-sensitive groups as yields rise.
• If the two-year yield breaks above 4.92%, the market will have started pricing a faster hiking path beyond December.
• The single risk to this thesis is that oil retreats, producer and consumer prices return to forecast, and the Fed softens its tone.
