US 30-Year Treasury Yield Hits Highest Since 2007 as Politicians and Wall Street Diverge on Fiscal Outlook

The US 30-year Treasury yield surged above 5.27%, hitting its highest level since 2007, as former House member Marjorie Taylor Greene voiced concerns over the expanding national deficit, warning that Social Security would go "bankrupt" by 2032. However, prominent Wall Street figure Louis Navellier dismissed the fiscal panic, backing US Treasury Secretary Scott Bessent and declaring, "I believe in Scott Bessent."

Political Warnings vs. Treasury Confidence

The surge in 30-year bond yields has sparked intense political and financial debate. Greene warned on platform X that "years of foreign wars and congressional overspending" are driving up government debt service obligations, predicting "national debt well over $50 trillion and interest over $2 trillion."

Years of foreign wars and congressional overspending have brought us to where we are now.

They are still launching more wars, which require more funding.

Just wait for Social Security to go bankrupt in 2032, with national debt well over $50 trillion and interest over $2 trillion.

In stark contrast, Navellier, founder and chief investment officer of Navellier & Associates, characterized the bond market volatility as a "non-event." Navellier said exclusively, "Under Scott Bessent, the yield curve is normalizing, and bid-to-cover ratios at Treasury auctions are healthy." He added that global "bond vigilantes are more focused on the UK, France, and Japan."

Experts Split on "Debt Spiral" Risk

Despite Navellier's optimism, financial strategists remain divided on whether elevated long-term yields signal structural fiscal danger. Alex Tsepaev, chief strategy officer at B2PRIME Group, warned that while a crisis is not imminent, "the runway is definitely shortening."

Tsepaev noted that when real interest rates exceed nominal GDP growth, "the classic debt spiral mechanism kicks in." He warned that sticky real yields above 5% would hit "long-duration growth stocks—unprofitable tech, speculative AI infrastructure, and high-multiple software companies."

Financial analyst Dean Chen offered a middle-ground view, describing the US economy as being in a "transition zone between rising fiscal stress and a self-reinforcing debt spiral." Chen pointed out that with sustained yields above 5%, private equity, venture capital, and real estate investment trusts face the sharpest valuation resets.

Fixed-Income Opportunity or Value Trap?

Discussing whether current levels represent a generational buying opportunity, Chen emphasized that "high yields and peak yields are two different things." He positioned current yields as "a highly attractive long-term fixed-income opportunity, but not yet an unconditional generational buy," advising investors to gradually add duration amid persistent inflation and fiscal uncertainty.

Meanwhile, Navellier stated, "The 'sweet spot' on the Treasury yield curve is between 2 and 5 years."

Market Context and Fiscal Environment

The yield spike to multi-decade highs comes as US national debt approaches $40 trillion, with fiscal-year deficits projected near $2.1 trillion, according to the Congressional Budget Office.

Economist Peter Schiff noted that the 30-year yield broke above 5.3% for the first time since April 2007, when national debt was below $8.8 trillion.

The 30-year Treasury yield has exceeded 5.3% for the first time since April 2007. At that time, US national debt was below $8.8 trillion. Now it exceeds $39.9 trillion, a more than 4.5-fold increase. Moreover, in 2007 bond yields were still trending lower. Now they are rising.

Meanwhile, finance professor David Kass cited Ed Yardeni's view that despite rising borrowing costs, broader equities remain reasonably valued.

Ed Yardeni: "Interestingly, despite the recent rise in the 10-year Treasury yield, the S&P 500 still looks slightly undervalued. If yields rise to 5.00%, the 'fair value' P/E ratio would be 20.0. That is roughly where we are now.
