The new leadership of the Federal Reserve is facing a significant test as inflationary pressures in the United States intensify and bond yields climb, according to a recent report by global brokerage Jefferies.
Inflation Data Raises Concerns
In its latest GREED & FEAR note titled "Bond pressures and AI resets," Jefferies highlighted that financial markets are entering a challenging phase following the release of the latest US inflation data. The report stated, "Financial markets remain set up for a test of the new Federal Reserve chairman following the release of the latest CPI data."
Headline CPI inflation in the US rose from 3.8% year-on-year in April to 4.2% in May, while core CPI inflation increased from 2.8% to 2.9%. Energy prices were a major contributor, with the Energy CPI surging by 23.5% YoY in May, marking the highest level since August 2022.
Geopolitical and Trade Factors
Jefferies noted that inflationary pressures are being exacerbated by geopolitical developments. The report commented, "While it is true that AI should turn out to be disinflationary, it will surely be hard for Kevin Warsh to look completely through the rising price pressures stemming from tariffs and, more importantly, the Iran conflict, most particularly as the Strait of Hormuz remains closed."
The brokerage also pointed out that producer price inflation remains elevated, with the PPI rising by 6.5% YoY in May, slightly above consensus estimates of 6.4%.
Bond Yields as a Key Indicator
Jefferies warned that bond market movements could become a crucial indicator for investors. The report emphasized, "GREED & fear continues to view the 10-year Treasury bond yield as the most important price in world markets."
The 10-year Treasury yield has climbed from a recent low of 3.92% in early March to 4.52%. Jefferies noted that "a clear break above the 4.5% level should be viewed by equity investors as a warning signal," while "a more decisive move above 5% would be more like a red traffic light."
Fiscal Concerns and Dollar Outlook
The brokerage also flagged growing concerns about the US fiscal position. Higher Treasury yields may initially support the dollar, but Jefferies warned that "sooner rather than later higher yields will become dollar bearish because markets will refocus on America's fiscal position, which in turn will lead to renewed focus on the US dollar debasement trade."
Gold and Investment Outlook
On gold, Jefferies maintained a constructive medium-term view despite near-term risks from rising yields and tighter monetary expectations. The report said gold remains vulnerable in the short term but added that investors should consider increasing exposure to gold-related stocks if prices move towards the lower end of the current trading range.
Jefferies concluded that inflation dynamics, Treasury yields, fiscal concerns, and the sustainability of the AI-led investment boom will remain key themes shaping global financial markets in the coming months.
