Treasury yields steady as Iran ceasefire strains and CPI nears

U.S. Treasury yields were little changed on Monday, July 13, 2026, even as a strained U.S.-Iran ceasefire and rising oil prices kept inflation fears in focus. The benchmark 10-year Treasury yield edged higher while the two-year note hit its highest level since early 2025, and investors turned to Tuesday's core inflation data for the next signal on Fed policy.

Monday's bond market looked calm on the surface, but the numbers told a more nuanced story. Geopolitical risk was back in the headlines, energy prices were climbing, and traders were still debating whether the Federal Reserve would need to tighten further. For anyone tracking fixed income, mortgages, or passive-income portfolios built around bonds, the 10-year Treasury yield remains the rate to watch.

Key Takeaways

• The 10-year U.S. Treasury yield rose marginally on Monday while the two-year yield climbed to roughly 4.24%, its highest since February 2025, according to CNBC and Bloomberg.
• A faltering U.S.-Iran ceasefire, fresh strikes, and a roughly 5% jump in Brent crude revived worries about war-driven inflation, even as longer-dated yields held relatively steady.
• June core CPI data due Tuesday is the next major catalyst, with readings arriving ahead of the Fed's July 27-28 meeting and Chair Kevin Warsh's first congressional appearance.
• A Reuters poll found most bond strategists still expect shorter-dated yields to ease over the coming year, though hawkish voices warn markets may be underestimating inflation.
• Higher Treasury yields can lift borrowing costs and shift the math on bond ladders, dividend strategies, and other wealth hacks and passive income plays tied to interest rates.

Why did Treasury yields barely move despite fresh U.S.-Iran strikes?

Over the weekend, the fragile ceasefire between the United States and Iran came under renewed strain. An Iranian strike on a commercial shipping vessel prompted fresh U.S. military action, and Iran responded with attacks on American bases across several Gulf states, deepening the standoff over the Strait of Hormuz.

That sequence cast doubt on an interim peace agreement signed last month after roughly 60 days of negotiations. The deal had aimed to reopen the vital shipping lane and ease a conflict that had already rattled energy markets. Yet on Monday, Treasury investors did not panic. CNBC reported that yields across the curve were broadly flat, with only modest moves at the front end.

The 10-year U.S. Treasury note yield rose marginally to about 4.57%. The 30-year bond yield was essentially unchanged near 5.07%. The long end of the curve absorbed geopolitical headlines without a dramatic repricing.

Markets often pause before major data releases. With core inflation figures scheduled for Tuesday and a packed economic calendar, many investors chose to wait rather than chase every headline from the Middle East.

What pushed the two-year Treasury yield to a 16-month high?

While the 10-year Treasury yield moved only slightly, the policy-sensitive two-year note told a sharper story. Bloomberg reported that the two-year yield rose as much as three basis points to 4.24%, marking its highest level in more than 16 months and the top reading since February 2025.

The driver was familiar: oil. Brent crude jumped about 5% after the latest exchange of strikes between Washington and Tehran. Energy costs feed directly into inflation expectations, and the two-year yield tends to react fastest when traders rethink the near-term path of Fed interest rates.

Swaps markets compiled by Bloomberg showed traders were nearly fully pricing a Fed rate hike in September, up from roughly a 66% probability just a week earlier. When short-term yields rise, newly issued Treasury bills and money-market funds can offer better returns, but existing bond holdings lose value.

Conflicting statements over whether the Strait of Hormuz remains open added another layer of uncertainty. The U.S. and Iran offered different accounts of commercial traffic through the chokepoint, leaving markets to price supply risk rather than clarity.

How does this week's inflation data affect the 10-year Treasury yield outlook?

Tuesday's release of June core inflation data sits at the center of this week's bond-market calendar. Core readings strip out volatile food and energy prices and give a cleaner read on underlying inflation, which is what the Fed watches most closely when setting policy.

A Bloomberg survey of economists suggested both headline and core CPI likely eased slightly in June, though both measures were still expected to remain well above the central bank's 2% target. Those figures will be among the final major inflation prints before the Federal Reserve's July 27-28 policy meeting.

Producer price data later in the week will add another piece to the puzzle. Stronger-than-expected numbers could reinforce the case for higher rates and keep upward pressure on the 10-year Treasury yield. Softer data could revive talk of eventual easing, though markets have largely priced out rate cuts for 2026.

Fed Chair Kevin Warsh is also scheduled to make his first appearance before Congress on Tuesday afternoon. Any signal on how the new leadership views inflation risk could move yields quickly, especially at the short end of the curve.

Do bond strategists expect the 10-year Treasury yield to keep rising?

Not everyone agrees on where yields go from here. A Reuters poll of bond strategists conducted July 6-9 found that renewed hostilities and a nearly 10% surge in oil prices had done little to change the median forecast for shorter-dated Treasuries.

Strategists still expected the two-year yield to fall from about 4.20% to roughly 4.00% within three months, then to 3.90% in six months and 3.85% in a year. For the 10-year Treasury yield, the median view pointed to stability near 4.48% before a modest decline to about 4.39% over the next 12 months.

That consensus rests on the idea that markets may eventually abandon bets on Fed rate hikes as economic data evolves. Treasury inflation breakeven rates remain elevated but have retreated from May's peaks.

Not all strategists share that view. Meghan Swiber of Bank of America noted that Fed officials see inflation risks tilted to the upside. BofA was the most hawkish firm in the survey, forecasting three quarter-point rate hikes in 2026. Mike Bell of RBC BlueBay argued markets may be underestimating inflation, suggesting Treasury yields are more likely to rise than fall.

What should passive-income investors watch next?

For investors building income around bonds, cash, or rate-sensitive dividend strategies, Monday's session was a reminder that headline calm can mask real movement at the short end. The 10-year Treasury yield may be the benchmark most Americans recognize, but the two-year yield is where Fed expectations live.

Three variables deserve close attention: Tuesday's core CPI print, any further escalation around the Strait of Hormuz, and Fed communication from Warsh and other policymakers. If yields stay elevated, savers may benefit from higher returns on short-term government debt, while borrowers face steeper mortgage costs tied to the long end.

The bond market did not scream on Monday, but geopolitical risk and inflation data are still in charge. Until one of them breaks decisively, expect the 10-year Treasury yield to trade in a tight range while the two-year yield does the heavier lifting.
