America’s $6 Trillion Interest-Rate Trap Is Spreading Far Beyond the Bond Market — and Investors Are Taking Notice

Ray Dalio spoke at the Milken Institute Asia Summit on Oct. 8. He warned that strong corporate earnings have helped stocks hold up as interest rates rise, and that the edge stocks hold over bonds is shrinking. His advice to investors was to look at free cash flow alongside earnings. Higher borrowing costs are now moving out of Washington and into housing, gold and AI spending, which makes that advice relevant.

How a $6 Trillion Federal Problem Reaches Your Portfolio

The Congressional Budget Office recently said that if rates average 1.5 percentage points above the CBO’s February baseline, deficits from 2026 through 2036 grow by $6 trillion. Higher interest on existing debt accounts for $4.9 trillion of that. Financing the extra borrowing adds another $1.1 trillion. Even before any rate shock, net interest is expected to rise from 3.3% of GDP in 2026 to 4.6% in 2036.

Markets are already pricing that pressure. The 10-year Treasury yield reached 5.22% on Oct. 8. Its one-year low was 3.97% in February. The Fed raised its upper target to 4.00% on Sept. 17.

Homebuilders Are Taking the First Hit

For its fiscal third quarter, Lennar (NYSE:LEN | LEN Price Prediction) reported revenue of $8.05 billion, down 8.5% from a year earlier. Its SEC filing shows homebuilding gross margin fell to 15.8% from 17.5%. Incentives ran at 12%, and in many markets almost 50% of visitors can’t immediately qualify for a mortgage. CEO Stuart Miller told analysts, “The Federal Reserve’s assistance is clearly off the table for practical purposes, and not a near-term source of relief.” The stock is down 23.73% year to date.

Berkshire Hathaway (NYSE:BRK-A)(NYSE:BRK-B) still added 2.42 million Lennar shares for about $193 million, raising its stake to roughly 12%. Lennar’s land-light model helps explain why Berkshire is willing to wait. The company owns about 2% of its homesites, and homebuilding debt is 16.6% of capital.

D.R. Horton (NYSE:DHI) has held up better. Its home sales gross margin was 20.7%, and its shares are down 5.51% this year. Its mortgage arm gave backlog buyers a 4.9% rate when the market rate was about 6.5%. Even so, cancellations rose to 20% from 17%. Existing home sales fell to an annualized 3.98 million, the lowest reading of the past year.

Gold Investors Kept Buying Through the Selloff

World Gold Council data show physically backed gold ETFs took in a record $31 billion in the third quarter. September alone brought $10 billion, even though gold fell 8.5% that month and the 10-year yield rose 53 basis points. Global holdings hit a record 4,256 metric tons. Spot gold recently traded near $4,194 per ounce.

Newmont (NYSE:NEM) received an average gold price of $4,414 per ounce and produced record second-quarter free cash flow of $2.21 billion. Wheaton Precious Metals (NYSE:WPM) grew second-quarter revenue 85% to $929 million. Management says the company generates more than $200 million in free cash flow each month, which it is using to pay down debt from its $4.3 billion Antamina stream. Newmont is up 18.8% this year, and Wheaton is up 18.49%. Wheaton has dropped 11.55% over the past month.

AI Spenders Face Dalio’s Free Cash Flow Test

Microsoft (NASDAQ:MSFT) shows why free cash flow matters. In fiscal 2026, net income rose 31.34%. Over the same year, capex climbed 79.62% to $115.95 billion and free cash flow fell 6.46%. Commercial remaining performance obligations of $678 billion support the expansion. The stock trades at about 30 times earnings.

NVIDIA (NASDAQ:NVDA) produced $21.34 billion in free cash flow on $96.22 billion of quarterly revenue. It also helps fund its customers. It has limited guarantee obligations of $108.5 billion and is working with Apollo, BlackRock, Blackstone and others to raise more than $500 billion in third-party capital. At 46 times earnings, that financing exposure needs a close look if rates stay high. The capital has to flow somewhere, and much of it lands with the power, cooling, and networking suppliers behind the data centers (we highlighted seven of them in a free report here).

What to Watch Before Year-End

Lennar guided fourth-quarter gross margin to 15.5% to 16.0%. That guidance assumed mortgage rates near 6.8%, and rates have since moved higher. NVIDIA needs to hit its $108.0 billion revenue guide. The 10-year yield will show whether gold’s ETF bid, homebuilder margins, and AI valuations can keep absorbing a rising cost of capital.
