The US Treasury market is sending a clear and urgent message to Federal Reserve Chair Walsh: his tough stance against inflation is far from sufficient to calm investor nerves.
A fresh military conflict between the US and Iran in July caught Wall Street off guard, briefly pushing international oil prices above $100 per barrel. This triggered a wave of selling in the $30 trillion Treasury market. The benchmark 10-year yield has surged over 30 basis points since the end of June, nearing 4.678%, a level close to a decade-high. Meanwhile, the more policy-sensitive 2-year yield has climbed to approximately 4.328%, breaking through the Fed's current 3.75% upper bound on its policy rate, reflecting strong market expectations for further rate increases.
The Fed is set to announce its latest policy decision on Wednesday. According to the CME FedWatch Tool, as of last Friday, the market priced in a 62% chance of a rate hold at this meeting. However, the probability of a rate hike has surged to about 38%, up sharply from roughly 13% just a week ago.
"This shows just how worried the market is about inflation, and how much it doubts the Fed's ability to walk the talk," said Gennadiy Goldberg, head of US rates strategy at TD Securities, referring directly to Walsh's series of public statements about bringing inflation back down to the 2% target.
Oil Shock and Bond Market Pressure Drive Yields Toward Decade Highs
The US-Iran conflict is the immediate catalyst for the recent rise in Treasury yields. Surging oil prices have intensified fears of a resurgence in inflation, prompting traders to dump government bonds en masse. According to GasBuddy, the average retail prices for regular gasoline and diesel in the US have recently climbed back above $4.00 and $5.20 per gallon, respectively.
The bond market experienced a brief rally after Walsh's first press conference as Fed Chair in June, but those gains have since evaporated. The 30-year Treasury yield remains stubbornly above the 5% level, inflicting significant losses on investors who had bet on longer-duration bonds.
"We did not anticipate this latest chapter in the US-Iran war, which is a complicating factor for any duration asset right now," wrote David Rosenberg, founder and president of Rosenberg Research & Associates, in a report last Friday. He also noted that a continuous expansion of corporate bond issuance, particularly from technology companies, is adding pressure to the Treasury market. Rosenberg stated he has adjusted his portfolio, switching from an underperforming long position in 30-year Treasuries to short-duration US government debt.
"The Fed needs to hear this signal," said Paul Christopher, head of global investment strategy at Wells Fargo Investment Institute. "Uncertainty is building up," he added, explaining that bond market investors are demanding compensation for this risk.
The Rate Hike Debate: The Cost and Timing of Policy Action
The Fed is not a unified front. Sources indicate that some members of the rate-setting committee are leaning towards raising rates to curb inflation. However, the problem lies in the extremely sensitive timing of any such action.
Inflation itself erodes the real value of fixed-income assets, while rate hikes would further depress bond prices and drag down other financial assets like stocks. At the same time, Barclays analysts estimate the US fiscal deficit for 2026 will be around $2 trillion. Sustained large-scale Treasury issuance will be crucial to fill this gap, suggesting that supply pressure in the bond market is unlikely to ease in the short term.
Furthermore, heavy borrowing by the technology sector is amplifying the pressure. Major tech companies, particularly so-called "hyperscale cloud providers," are racing to issue corporate bonds to fund their artificial intelligence infrastructure buildout, pushing up overall borrowing costs. In a report last Wednesday, Moody's Ratings estimated that capital spending by these hyperscale cloud providers could approach $1 trillion by 2027, following nearly $800 billion this year, and warned that "soaring capital spending, rising leverage, and off-balance-sheet commitments" pose a threat to the credit quality of this group.
Stock Market Takes Another Hit, Led by Tech Stocks
The shadow of higher interest rate expectations is also hanging over the stock market. Last week, semiconductor stocks led the decline, with the Philadelphia Semiconductor Index falling over 4% for the week. The Dow Jones Industrial Average dropped 0.4% for the week, the S&P 500 fell 0.6%, and the Nasdaq Composite slumped a sharp 2.1%. The Nasdaq's closing price is now 7.8% below its all-time high set in early June.
Higher interest rates typically suppress corporate and consumer spending, thereby slowing economic growth and eroding corporate earnings expectations. Wells Fargo's Christopher suggested that investors could wait for the current rotation out of tech stocks to run its course, at which point "there could be a good entry opportunity." He also advised that "holding some cash reserves might not be a bad idea."
