Nasdaq-100 Record vs 5.31% Treasury Yield: A Real Rate Bet

The 10 year Treasury closed at 5.31%, a 24 year high, and 102 of this year's 113 basis point rise is real yield. The Nasdaq-100 is pricing AI profits against a discount rate the Fed does not recognise.

The Nasdaq-100 closed Monday at about 31,076, up 0.87% and above Friday's record close of 30,808, according to Nasdaq Indexes. The same session closed with the 10 year Treasury at 5.31% on the Treasury's par curve, a level last touched on a close in May 2002. Stock and bond investors are looking at the same economy and have priced it with very different discount rates.

The bond market has the better of the argument. The rise in yields this year has come almost entirely from the real component, the part that compensates a lender for time rather than for inflation, and the Fed's own projections put the long run level of that component far below where the market now sits. The Nasdaq-100 is betting that the gap closes from the bond side. Until payrolls or Treasury supply change the picture, that is not a bet to take.

The decomposition is the place to see it. On the Treasury's real par curve, the 10 year real yield was 1.93% on December 31 and 2.95% on Monday, the highest since November 2008. The nominal yield rose from 4.18% to 5.31% over the same stretch, a gain of 113 basis points. Real yield supplied 102 of them. The implied breakeven, the market's price for inflation, moved from 2.25% to 2.36%, or 11 basis points. September alone took the nominal yield from 4.75% to 5.29%, and 49 of those 54 basis points were real.

Investors have not suddenly started to fear inflation; breakevens have barely moved. What has changed is the price of waiting, and it has changed fastest in the long end: the 30 year closed at 5.66%, a level not seen on a close since July 2001, and the 2 year at 4.84% sits 47 basis points below the 10 year. A rise concentrated in real yield at long maturities is a rise in the rent that capital charges, and the Nasdaq-100 is priced on earnings a long way out.

The Fed's own numbers show how far the market has travelled. In the Fed's September projections, the median longer run federal funds rate is 3.2% and longer run PCE inflation is 2.0%. Take one from the other and the neutral real rate is 1.2%. The 10 year real yield is 2.95%, which leaves a premium of about 175 basis points over what policymakers think is normal. Equities are implicitly assuming that premium is temporary. The bond market is pricing it as a feature of the next several years.

That premium exists even though the Fed has not been timid. On September 16 the committee voted 12 to 0 to raise the target range by a quarter point, to 3 3/4 to 4 percent, and the same projections show the median path ending 2026 at 4.1%, one more quarter point. Inflation is the reason: 2026 PCE inflation is projected at 3.7%, with the core measure at 3.4%, and the BLS put August CPI at 3.4% over 12 months after a 0.4% monthly gain. The 10 year now yields 131 basis points above the top of the policy range, so the market is charging a term premium on top of a Fed that is already tightening.

The equity side has a case. Lisa Shalett, chief investment officer of Morgan Stanley Wealth Management, said, in comments carried by Reuters, that relative equity calm amid the bond market's "perfect storm" is understandable "given accelerating economic growth and the AI boom's rate insensitivity", and the Fed's September statement itself credits strong productivity growth and heavy capital investment. If AI spending is paid from cash flow, a higher yield does not stop it. Spending may ignore rates; valuation cannot. The index capitalises earnings a decade out, so the discount rate matters whether or not the cheque is written from retained cash, and the economy outside AI is not producing the income that would carry a 5.31% yield: average hourly earnings are rising 3.0% over 12 months against CPI at 3.4%.

The payrolls report shows the pattern. The September Employment Situation, released on Friday, showed a gain of 29,000 jobs, with unemployment at 4.2%, and revised July to a loss of 10,000 and August to a gain of 133,000. Weak hiring ordinarily pulls yields down. This time the 10 year closed Friday at 5.28%, barely below its 5.29% close on September 30, and went to 5.31% on Monday. A market trading a softer economy would have rallied; this one is asking for more compensation to hold duration, and with breakevens flat the extra payment is for the volume of paper to be absorbed, not for inflation.

The September statement said job gains had kept pace with the workforce; a 29,000 gain and a revised July loss leave that sentence out of date. Weakness in jobs will not necessarily pull yields down while supply is driving them, and strength would argue for a higher neutral rate, so policy has little to offer a stock market priced on a low one.

By the Fed's decision on October 28 the 10 year real yield will be at or above 3%, a level that would put the Nasdaq-100's record at risk, because equities have so far absorbed a 2.95% real yield only on the assumption that it is a temporary overshoot. The October 27 and 28 meeting arrives with the index at a record and the long end still repricing beneath it.
