30-year Treasury yield hits highest level since 2004 — what it means for stocks: Chart of the Day

The 30-year Treasury ( ^TYX ) yield rose to its highest level since 2004 on Thursday as stocks fell, raising questions about whether volatility in bond yields could prompt a larger pullback in equities.

The 10-year Treasury yield ( ^TNX ), a benchmark for mortgage rates and loans, hovered near its 2007 highs , while the 30-year Treasury yield stood at 5.4% Thursday morning. Meanwhile, stock futures fell .

The move comes as oil prices climbed toward $100 per barrel after President Trump signaled support for a US diesel export ban . Business activity data that came in hotter-than-expected fueled concerns about persistent inflation.

The main driver behind rising rates is "the US economy is booming," Ed Yardeni of Yardeni Research wrote in a note.

Notably, the US dollar has risen to an eight-week high, contributing to downbeat sentiment in just the last couple of days.

"The run-up in the dollar, I think, is associated with negative risk sentiment. And so I think that's affecting equities as well," Steve Englander, co-head of FX Research at Standard Chartered, told Yahoo Finance.

Hawkish remarks from Fed governor Michael Barr also raised expectations of tighter monetary policy among Fed officials. Investors raised their bets on another Fed rate hike in October to 64%.

"There is a sense that the Fed and central banks globally are not willing to tolerate another inflationary shock," Englander added.

The declines in the stock market so far have been measured. Nasdaq Composite ( ^IXIC ), which posted back-to-back records earlier this week, fell 1% on Wednesday. Most of the declines have centered on interest-rate-sensitive sectors like Utilities ( XLU ), Real Estate ( XLRE ), and Financial Services ( XLF ).

"So far, stocks have continued to shrug off bad news in the most surprising ways," said Dean Lyulkin, president of lending company Cardiff.

The question is whether stocks can keep shrugging off higher rates.

More hikes "could create further strain for already constrained, interest-sensitive sectors while doing little to slow the AI-led investment surge, though it could increase the risk of a stock market correction," EY-Parthenon chief economist Gregory Daco said.

For now, some strategists see small stock market declines as buying opportunities.

"Until US equity indices begin to show more evidence of downside acceleration on this pullback attempt, it's right to consider pullbacks as representing attractive risk/reward opportunities," wrote Mark Newton, head of technical strategy at Fundstrat.
