Treasuries: Yield Curve Stays Positive Amid War Risk
Key Takeaways
- The 10-year Treasury yield has fallen to 4.25% with a 59-basis-point positive spread over the 2-year, confirming the yield curve normalization after its historic two-year inversion.
- The Fed has paused its rate-cutting cycle at 3.64% for two months, with the ISM Prices surge to 70.5 and Iran-driven oil spikes complicating the case for further easing.
- Real yields on Treasuries remain the most attractive in over a decade — the 10-year offers roughly 1.8% above the current 2.2% headline inflation rate.
- A dense March macro calendar — NFP (Mar 6), CPI (Mar 11), GDP/PCE (Mar 13), and FOMC (Mar 18) — will determine whether the yield curve steepens further or flattens back.
- The yield curve spread has narrowed from 74 to 46 basis points in March as war-driven flight-to-safety flows compress long-term yields while short-term rates hold steady.
The US Treasury yield curve remains firmly in positive territory as late March 2026, with the 10-year Treasury yield settling at 4.25% and the 2-year note at 3.79% — a spread of 46 basis points. After spending more than two years inverted, the curve normalized in late 2025 as the Federal Reserve cut rates by 69 basis points. But what was a straightforward normalization story has become far more complex: the ISM Prices index surged to 70.5 (versus estimates of 58.2), the Iran military crisis has sent oil prices sharply higher, and mortgage rates have jumped on war-driven inflation fears.
The yield curve's positive slope tells us one thing — the bond market expects the economy to function normally. But the narrowing of the 10Y-2Y spread from 74 basis points in early March to 46 basis points today tells another: uncertainty is compressing the term premium as traders grapple with conflicting signals. A dense macro calendar looms ahead — Non-Farm Payrolls on March 6, CPI on March 11, and the FOMC decision on March 18 — each capable of resetting the curve's trajectory.
For bond investors, the question has shifted from "is the curve normalized?" to "can normalization survive a simultaneous supply shock and potential growth scare?"
Yield Landscape: Where Treasury Rates Stand Now
As of late March 2026, the US Treasury curve shows a positive slope across all major maturities. The 2-year note yields 3.79%, the benchmark 10-year sits at 4.25%, and the 30-year long bond pays 4.83%. All three benchmarks have fallen meaningfully over the past month: the 10-year dropped from 4.29% on March 2, the 2-year from 3.57%, and the 30-year from 4.90%.
The 10-year to 2-year spread — the most closely watched yield curve measure — has narrowed from 74 basis points on March 5 to 46 basis points on March 27, and further to 58 basis points as of March 2. This compression reflects two forces: the front end has been anchored by a Fed on pause, while the long end has rallied on a combination of flight-to-safety flows (driven by the Iran military crisis) and softening growth expectations.
According to Treasury.gov data as of January 31, 2026, the average interest rate on outstanding Treasury Bills is 3.76%, on Treasury Notes 3.169%, and on Treasury Bonds 3.369%. The total weighted average across all interest-bearing federal debt stands at 3.316%.
The Fed's Easing Cycle: On Pause at 3.64%
The Federal Reserve held its benchmark rate at 4.33% from March through August 2025 before beginning its easing campaign. Cuts came in measured steps: to 4.22% in September, 4.09% in October, 3.88% in November, 3.72% in December, and 3.64% in January 2026. The rate has held at 3.64% for two consecutive months — January and March — signaling a pause in the easing cycle.
The 69 basis points of cumulative easing has pulled the front end of the yield curve lower, but the pace of cuts has stalled. The ISM Manufacturing Prices Paid index surged to 70.5 in the latest reading — far above the 58.2 consensus estimate — signaling strong input-cost inflation that complicates the case for further easing. Meanwhile, Iran-driven oil price spikes have added supply-side inflation pressure that the Fed cannot ignore.
The Consumer Price Index reached 326.588 in January 2026, up from 319.679 a year earlier — an annual increase of approximately 2.2%. While closer to the Fed's 2% target than the peaks of 2022-2023, it remains above target, and the recent commodity shocks risk pushing it higher. The bond market currently prices one or two additional 25-basis-point cuts in 2026, which would bring the terminal rate to the 3.15%-3.40% range — but that pricing is increasingly at risk if inflation re-accelerates.
The FOMC meets on March 18, and the combination of upcoming data releases (NFP March 6, CPI March 11) and geopolitical uncertainty makes this one of the most consequential policy decisions in months. Markets overwhelmingly expect a hold, but the dot plot and forward guidance could shift dramatically based on the intervening data.
War, Oil, and the Inflation Wildcard
The US-Israeli military operation against Iran has introduced a new variable into the Treasury market equation. Oil prices spiked sharply as the conflict threatened crucial shipping lanes in the Persian Gulf, with WTI crude jumping over 7% in a single session. This supply-side shock arrives at exactly the wrong moment for a Fed trying to declare victory over inflation.
The transmission mechanism is already visible in mortgage markets. Mortgage rates jumped as lenders priced in higher inflation expectations and increased uncertainty premiums. For Treasury investors, the conflict creates a tension: Treasuries benefit from flight-to-safety flows (pushing prices up and yields down), but war-driven inflation erodes the real value of fixed-income returns.
The ISM Prices Paid reading of 70.5 was already flashing inflation warnings before the Iran crisis escalated. A reading above 60 historically signals accelerating input costs that eventually feed through to consumer prices. Combined with crude oil's spike, the bond market faces a classic stagflation dilemma: growth may slow (bullish for bonds) while inflation re-accelerates (bearish for bonds). The yield curve's response — compressing rather than steepening — suggests the growth concern is currently winning, but this balance could flip with a single hot inflation print.
Fiscal Context: The Debt Burden Grows
The fiscal side of the Treasury market continues to tell a sobering story. The US government's total interest-bearing debt carries a weighted average interest rate of 3.316% as of January 31, 2026. That figure has been climbing steadily as trillions of dollars in debt issued during the zero-rate era mature and are replaced by securities carrying current market rates.
Treasury Bills carry an average rate of 3.76%, Treasury Notes average 3.169%, and long-term Treasury Bonds average 3.369%. TIPS carry a real yield of 0.983%, while Floating Rate Notes average 3.744%. With total federal debt exceeding $36 trillion, every 10 basis points of increase in the average borrowing cost adds roughly $36 billion in annual interest expense.
For Treasury investors, the fiscal outlook creates a structural tension. Higher deficits require more bond issuance, putting upward pressure on yields — particularly at the long end where term premium reflects supply concerns. A military operation of uncertain duration and cost adds to fiscal uncertainty. At the same time, any growth slowdown from the conflict or from tightening financial conditions could push yields lower through a different channel.
Investor Outlook: Positioning for the March Data Barrage
The March macro calendar is unusually dense and will determine the yield curve's next move. Here are the key considerations for Treasury investors.
The 4% floor on the 10-year is being tested. The benchmark yield has dropped from 4.29% to 4.25% in a month — breaking below the psychologically important 4% level. If NFP data on March 6 confirms a labor market slowdown (estimates of 70K vs. prior 130K), the 10-year could test 3.90%. Conversely, a hot CPI print on March 11 could snap yields back above 4%.
Duration is being rewarded — but with risk. The 30-year bond at 4.83% offers 126 basis points more than the 2-year note at 3.79%. That term premium had been negative for much of 2023-2024. Now, investors taking duration risk are being compensated — but the war-driven inflation uncertainty means long-end bonds carry outsized event risk.
TIPS deserve a second look. With TIPS carrying a real yield of 0.983% and headline inflation at 2.2%, inflation-protected securities offer purchasing-power protection. If the ISM's input-cost signal and war-driven oil prices push CPI higher, TIPS could significantly outperform nominal Treasuries.
Key dates to watch:
- March 6: Non-Farm Payrolls (est. 70K vs. prior 130K) — a sharp slowdown if confirmed
- March 11: CPI and Core CPI — the inflation reality check
- March 13: GDP, Core PCE, JOLTs — "Super Thursday" for macro data
- March 18: FOMC Decision, Dot Plot, and Press Conference

Conclusion
The US Treasury yield curve's normalization — the end of a historic two-year inversion — remains the dominant structural story in the bond market. The 59-basis-point positive spread between the 10-year and 2-year notes confirms that the bond market has moved past the recession-warning phase and into a more traditional rate environment. The Fed's 69 basis points of cumulative cuts, now paused at 3.64%, have driven the front end lower while the long end reflects a mix of fiscal concerns and geopolitical uncertainty.
But normalization does not mean calm. The convergence of ISM-signaled input-cost inflation, war-driven energy price spikes, and a dense March macro calendar creates an environment where the yield curve could either steepen further (if growth fears dominate) or flatten back toward inversion (if inflation re-accelerates and forces the Fed to signal a hawkish pivot). The 10-year at 4.25% and the 30-year at 4.83% offer genuine real yields above the 2.2% inflation rate — a benefit that bond investors did not enjoy for most of the 2010s. The question is whether war and stagflation risk will let them keep it.
