The whole curve in 2018
A single year's curve is best read maturity by maturity, and the interactive chart above lets you hover any point on it. In broad strokes, 2018 opened at the short end with three-month bills near 2.01% and the two-year note around 2.53%, rose through the belly of the curve to the 2.89% ten-year benchmark, and reached out to roughly 3.1% on the thirty-year long bond. That is a span of about +1.09 points from the shortest bills to the longest bond — a clearly upward-sloping, "normal" curve, with investors paid meaningfully more to lend for longer.
The short end versus the long end
The two halves of the curve are driven by different forces. The short end — the 3-month bill at 2.01% and the 2-year note at 2.53% in 2018 — moves with the Federal Reserve's policy rate and with expectations for where it's headed. The long end — the 10-year at 2.89% and the 30-year at 3.1% — is set more by the market's view of long-run growth and inflation. When the Fed is hiking aggressively, the short end can climb above the long end, and the curve inverts. In 2018 the 10-year sat +0.88 relative to the 3-month bill.
What the 2018 curve signaled
The Fed raised rates four times and the 10-year briefly topped 3% for the first time in years, while the gap between 2-year and 10-year yields narrowed toward zero.
Across 2018 the 10-year Treasury averaged 2.89% and the 2-year 2.53%, leaving the 10y−2y spread at +0.36. That kept the curve in its normal, upward-sloping shape, with investors paid more to lend for longer — generally a sign the market isn't pricing in an imminent downturn.
The 10-year's path through 2018
The benchmark 10-year didn't sit still during the year. It ended roughly flat, moving from about 2.72% at the start of 2018 to 2.69% by year-end, and traded between roughly 2.69% and 3.15% along the way. For anyone shopping for a mortgage that year, those swings mattered: the 30-year fixed is priced off the 10-year, so its rise and fall showed up in home-loan quotes within weeks.

How 2018 compares with today — and its own decade
The 10-year sits at about 4.38% today, so 2018's 2.89% was below the current level — the 7th-highest of the 17 years in this record. The spread has since moved to +0.28, so the curve is back to its normal upward slope. Within the 2010s, the 10-year averaged about 2.38%, and 2018 ran above its own decade. A year earlier, in 2017, the 10-year averaged 2.33% with a +0.91 spread. The following year, 2019, it eased to 2.08%.
The curve doesn't move on its own — it's driven by the Fed at the short end and by growth and inflation expectations at the long end. See what the Fed's policy rate did in 2018, and how mortgage rates moved in 2018 as a result.
