Stocks hold up as 10-year Treasury yield nears 19-year high, with locked-in fixed-rate corporate debt slowing the impact
U.S. stocks have stayed resilient while the 10-year Treasury yield sits near its highest since 2007. TKer's Sam Ro attributes this to long-dated, fixed-rate corporate debt. Federal Reserve research supports this, but the protection weakens as debt matures and is refinanced at current rates.

Reach: not measured yet
The 10-year yield reached 5.23% in late September, its highest since 2007, before easing to 4.86% by Nov. 6. Ro's post says the S&P 500 was still up about 10% for the year and about 4% below its record. His explanation is that companies locked in long-dated, fixed-rate debt. Fed research finds that about 80% of debt owed by U.S. public non-financial companies is fixed-rate, so higher rates raise their interest costs only as old debt matures and is refinanced. [1] [2] [3] [11]
The cushion shrinks over time and is uneven across companies. The Fed's 2024 projection put about 40% of corporate bonds as issued after the tightening that began in 2022. Smaller firms, cyclical firms, and firms with floating-rate, short-maturity or bank-loan debt are more exposed. In a 2023 Fed study, each 1-point rise in policy rates raised interest costs 32 basis points more for the most bank-reliant firms than for the least reliant. [3] [10]
New borrowing is priced at today's rates. Large tech firms borrowed $132 billion for AI infrastructure through July. CNBC's account of the yield surge points to bond issuance, deficits and AI-related borrowing, not just Fed policy, as forces pushing long-term yields up. [2]
Policy pressure is building. The Fed raised rates in September to 3.75%–4%, its first hike since July 2023. In October it held rates, with two officials voting for another hike. After October consumer prices rose 0.4%, above forecasts, markets put the odds of a December hike near 90%, yet the S&P 500 still gained 1.31% that day. [5] [6] [7] [8]
about 80% of public non-financial corporate debt is fixed-rate, so rate hikes reach interest costs slowly.

Implication: the cushion buys time rather than immunity, and firms borrowing now, including AI infrastructure builders, pay today's higher rates.
Drafting the dossier now. I've checked the market data, the Fed decisions and the Federal Reserve research on corporate debt.
Executive brief
The 10-year Treasury yield hit 5.23% in late September, its highest level since 2007. Even so, the S&P 500 was up 10% for the year and only 4% below its record, according to TKer's Sam Ro. The post's web address points to its explanation: companies locked in long-dated, fixed-rate debt. Federal Reserve research supports the idea. About 80% of debt owed by U.S. public non-financial companies is fixed-rate, so higher rates raise their costs only as old debt matures and is refinanced. That protection is real, but it fades as debt rolls over.
What changed and event timeline
10-year yield passes its 2007 high
The yield rose to 5.04% as traders bet on a Fed rate hike. The move was part of a global bond selloff driven by heavy capital spending and higher energy prices ().
First Fed hike since July 2023
The Fed voted 12–0 to raise its target range to 3.75%–4%. Chair Kevin Warsh said inflation remains elevated. Officials projected headline inflation of 3.7% for 2026 ().
10-year reaches 5.23%
Macquarie's Thierry Wizman blamed bond issuance more than inflation. CNBC also pointed to deficits and AI-infrastructure borrowing ().
Fed holds, with two dissents
The Fed kept rates at 3.75%–4% on a 10–2 vote. Governor Lisa Cook and Cleveland Fed President Beth Hammack wanted another hike (;).
TKer publishes its argument
Ro says long-dated fixed-rate debt explains why stocks have held up while yields sit near 19-year highs ().
Hot inflation report, stocks still rise
October consumer prices rose 0.4% for the month, above forecasts. Markets put the odds of a December hike near 90%. The S&P 500 still rose 1.31% to 7,619.38 ().

This section covers which companies are protected and which are exposed:
- Large companies: Goldman reportedly puts large-company interest coverage (how many times earnings cover interest payments) at the 99th historical percentile (Tiger Brokers summary of Goldman).
- Exposed companies: smaller firms, cyclical businesses, firms with floating-rate or short-maturity debt, and heavy bank borrowers (Fed, 2024; Fed, 2023).
- New borrowers: pay current rates. Large tech firms borrowed $132B for AI infrastructure through July (CNBC).
Technical analysis for researchers and developers
- How rates reach companies: interest costs on fixed-rate debt change only for the share that matures.
- Fed 2023 study: used a panel regression across advanced economies. The study projected 16%–32% of bonds maturing by end-2025 (Fed, 2023).
- Fed 2024 stress test: ran baseline, stagflation and severe-recession scenarios. In the recession case, interest coverage fell to Great Recession levels (Fed, 2024).

- How rates reach companies: interest costs on fixed-rate debt change only for the share that matures. Higher policy rates therefore feed through slowly to average interest costs.
- Fed 2023 study: used a panel regression across advanced economies. Each 1-point rise in policy rates raised interest costs 32 basis points more for firms most reliant on bank loans than for the least reliant. The study projected 16%–32% of bonds maturing by end-2025 (Fed, 2023).
- Fed 2024 stress test: ran baseline, stagflation and severe-recession scenarios. In the recession case, interest coverage fell to Great Recession levels (Fed, 2024).

Claims and evidence
- The 10-year is near its highest since 2007. Market data confirm it (CNBC). It had eased to 4.86% by Nov 6.
- Fixed-rate debt protects companies. The Fed's 80% fixed-rate figure supports this.
- Earnings, not rates, drive the market. This is Goldman's view, reported secondhand. It is a forecast, not observed data.

- Fixed-rate debt protects companies. The Fed's 80% fixed-rate figure supports this.
- Earnings, not rates, drive the market. This is Goldman's view, reported secondhand. Goldman projects S&P 500 earnings of $340 per share in 2026, up 24% (Tiger Brokers). It is a forecast, not observed data.
- The "10% for the year, 4% below the record" figures come from Ro's post. No primary index data in the reviewed sources confirms them.
Context and prior work
Ro has made this argument before. In August 2023 he wrote that higher rates hadn't materially hurt corporate profits. That 2022–23 cycle is the base for the Fed studies cited here. The difference in 2026: long-term yields are being pushed up by bond issuance and AI-related borrowing, not only by Fed policy (CNBC).
Limitations, safety and contested findings
- Pandemic refinancing may not have helped as much as assumed.
- They hold more than two-thirds of the debt the Fed classed as vulnerable in its baseline scenario (Fed, 2024).
- Goldman reportedly says the S&P 500's forward price-to-earnings ratio fell from 22x to 19x this year (Tiger Brokers).

- Pandemic refinancing may not have helped as much as assumed. The Fed's 2023 study found the pass-through to existing debt was statistically indistinguishable from earlier tightening cycles. That cuts against the view that companies locking in longer maturities during the pandemic slowed the hit (Fed, 2023).
- Investment-grade firms aren't immune. They hold more than two-thirds of the debt the Fed classed as vulnerable in its baseline scenario (Fed, 2024).
- Valuations still fell. Goldman reportedly says the S&P 500's forward price-to-earnings ratio fell from 22x to 19x this year (Tiger Brokers).
- The Fed data are from 2023–24 and have not been updated for 2026.
Business and practitioner implications
- Each year of maturities moves more debt to current rates. By the Fed's 2024 projection, about 40% of corporate bonds would be issued after the tightening that began in 2022.
- AI infrastructure is being financed at today's rates, not locked-in older rates, so heavy builders face higher funding costs.
- Policy pressure is rising. Markets are pricing a December hike near 90% after the October inflation report.
