Gundlach Warns: Long-End Rates Will Surge Significantly If the Fed Stands Pat
nashnova research
DoubleLine CEO Jeffrey Gundlach issued multiple warnings ahead of next week's Fed meeting: no hike means long-end rates rise sharply, today's inflation path looks "eerily similar" to the 1970s, AI corporate spreads have nearly doubled, and U.S. equity valuations leave "no bargains."
What happens if the Fed doesn't hike?
Gundlach stated plainly: if the Fed stays put next week, long-term rates will see "a fairly significant rise"; if it hikes, bonds may hold current levels.
This means → markets price a roughly 60% probability of a hike, but Gundlach sees that as too optimistic — the chance of no hike is underpriced.
His 10-year Treasury yield model — built on Germany's 10-year yield and the 7-year average of U.S. nominal GDP, with an R² of 0.93 — puts fair value at about 4.71%. The actual yield sits at 4.78%, roughly in line.
In plain terms = after roughly 500 basis points of hikes with no meaningful pullback, "the path of least resistance is probably higher."
Is inflation actually cooling?
Gundlach pushed back hard on market optimism: the 6-month annualized rates of both core PCE — personal consumption expenditures, the Fed's preferred inflation gauge — and headline PCE run above their 12-month rates. "Inflation hasn't really improved — it's nowhere near 2%."
He overlaid the post-2014 inflation curve on the 1960s-to-early-1980s surge and concluded the paths are "eerily similar" — pointing straight at the pre-Volcker inflation disaster.
On his preferred non-seasonally-adjusted indicator: U.S. export prices are up 8.25% year-on-year, import prices up 5.95%, averaging to an effective inflation rate of roughly 7%.
This reflects strong floor support from oil — Brent crude near $100 a barrel, global inventories at their lowest since 2018; the Bloomberg commodity index up 34% since the start of the war; residential electricity prices up over 50%, from about 12.5 cents/kWh to 18 cents.
What's wrong with AI corporate debt?
Broad investment-grade spreads — the extra yield a bond pays over Treasuries, reflecting the market's default-risk pricing — have barely moved. But AI-sector investment-grade spreads have jumped from 50 bps to roughly 125 bps, widening by 75 bps.
In high yield — lower-rated, higher-default-risk bonds — AI-related spreads surged from about 180 bps to around 325 bps.
This means → the market cannot digest the "avalanche" of AI bond supply, and spread pressure will keep building.
In plain terms = the AI industry is borrowing too much, too fast. Investors are demanding higher risk compensation — a signal buried under the calm surface of the broader credit market.
Just how expensive are U.S. equities?
The S&P 500's Shiller P/E — CAPE, which smooths earnings over ten inflation-adjusted years — has hit 42×, well above the eve of the 1929 crash.
Gundlach's blunt assessment: at this P/E level, the next decade's real returns have never been positive — historically they run negative 5% to negative 9% per year.
Information technology's weight in the S&P 500 has reached a record 38%, exceeding concentration levels before both the 1999 dot-com bubble and the 2008 financial crisis.
In plain terms = "extreme concentration = extreme danger" — Gundlach says he would not recommend any cap-weighted equity exposure.
What does he like — and what does he avoid?
Bearish on the dollar: the DXY has fallen from a late-2024 high of 110 to below 100; Gundlach expects further weakness.
Bullish on emerging markets: dollar weakness correlates strongly with EM outperformance — since late 2024, the S&P 500 has underperformed EM by roughly 20%. He also favors EM local-currency debt.
This means → in his framework, capital is rotating out of U.S. assets into emerging markets on a large scale, and that shift is not over.
Can long-dated TIPS hedge the risk?
Gundlach flags a common misconception: 30-year TIPS and 30-year nominal Treasuries have moved in lockstep since late 2021.
In plain terms = "If you don't like long nominal Treasuries, there's no reason to believe 30-year TIPS will protect you" — TIPS are not a hedge against long-end rate risk.
U.S. public debt has reached $40 trillion; at the current trajectory it could top $50 trillion by 2032. He is equally skeptical of the Treasury's newly announced buyback program, calling its likely impact on long-end yields limited.
This reflects the stakes of next Wednesday's Fed decision — the first critical test of every call Gundlach has laid out.
