Robert Shiller Releases Biggest Warning Yet. ("the second biggest bubble in history is coming")

44.2. That was the Shiller PE ratio in December 1999. 3 months later, the Nasdaq peaked. Within 21 months, it had lost 78% of its value. Trillions of dollars in household wealth vanished.

Today, the same index reads 42.66, the second highest level in 145 years. And the man who built it, Robert Shiller, has just released the biggest warning of his career. His forecasting model projects the S&P 500 will land at 6,381 by the end of 2035. The index sits near 6,000 today. 10 years, 6% of total nominal return. After inflation, negative.

Robert Shiller is a Nobel laureate. He built the Case-Shiller Home Price Index, the official tool for measuring housing bubbles. He built the Shiller PE ratio, the official tool for measuring stock market bubbles. He's the only economist in modern history who built the benchmark for both. He called the dot-com peak in March 2000. He called the housing bubble in 2005.

Today, his stock index is flashing near record extremes, while his housing index shows real home prices falling for nine straight months. The man who built both warning systems is watching both systems flash red at the same time. He's calling this the second biggest stock bubble in history.

Another lost decade is coming, and the catastrophe that follows will not hit the way most housing analysts think it will. So, today we're breaking down the 78 billion dollars in homeowner equity that has already evaporated this cycle, according to CoreLogic, formerly CoreLogic. The one mechanism connecting a stock market correction directly to your home's value, and the reason most housing analysts have the dominoes falling in the wrong order.

Here's what you need to understand about Robert Shiller before we touch a a piece of data. This is a man who has spent 50 years building the two most important early warning systems in American finance. In 2013, the Royal Swedish Academy of Sciences awarded him the Nobel Prize in Economic Sciences, shared with Eugene Fama and Lars Peter Hansen, for empirical analysis of asset prices. The specific finding that earned him the prize: that stock prices exhibit what he called "excess volatility," meaning they move far more than fundamentals justify. In other words, markets get carried away. They overshoot. They tell themselves stories.

In March of 2000, 3 weeks before the Nasdaq peaked, Shiller published the first edition of "Irrational Exuberance." The book argued that the stock market was a bubble driven by feedback and psychology, not fundamentals. The dot-com crash began within weeks.

In 2005, he released the second edition, added a chapter on housing, warned that further rises in the stock and housing markets could lead, eventually, to even more significant declines. A long-run consequence could be a decline in consumer and business confidence and another, possibly worldwide, recession. The housing market peaked in 2006. The global financial crisis arrived in 2008.

Now, here's the part nobody talks about. Shiller didn't just predict those two crashes. He built the official measurement tools that are still used to detect bubbles today. The Case-Shiller Home Price Index, which he deployed with Karl Case in the late 1980s, is the tool the Federal Reserve, the Treasury Department, and every serious housing economist uses to track home prices. The Shiller P/E ratio, what Wall Street calls the CAPE, is the long cycle valuation tool used to identify stock market bubbles. He built both. He created the dashboards, and both of his dashboards are screaming right now.

In his most recent quarterly market forecast, released in late 2025 and largely ignored by mainstream housing media, Shiller wrote one specific line that should stop every homeowner watching this video cold. Quote: "Anytime a group of stocks gets a name or becomes a meme, this is a sign of at least temporarily a strong narrative as in the late 1990s and today." That is the Nobel laureate who called the dot com peak telling you in writing that today looks like 1999.

Now, let's get to your home, because that's where this video gets uncomfortable. The National Association of Realtors released April 2026 existing home sales on May 11th. The annualized pace came in at 4.02 million homes, flat year-over-year. That number is sitting at roughly the same level it was in 2010, the depth of the foreclosure crisis, and it's happening while the United States has roughly 6 million more jobs today than we did in 2019. The market has more workers, more income, and a larger population than ever, and turnover is matching post-crash levels.

Median home price came in at $417,700 in April, up 0.9% year-over-year. That marks the 34th consecutive month of year-over-year price increases. But, here's the screenshot-worthy line from the same release: "According to the S&P CoreLogic Case-Shiller National Home Price Index," say that 10 times fast, "Shiller's own index, for nine consecutive months inflation has run faster than home price appreciation." In real terms, your home is losing purchasing power right now.

Inventory climbed to 4.4 months of supply. More than half of the 20 metros tracked by Case-Shiller posted year-over-year price declines. Chicago is the strongest market in America at plus 5%. Denver is the weakest at -2.2%. Tampa, Phoenix, Dallas, all negative.

And here's the cliffhanger. CoreLogic, formerly CoreLogic, released their Q4 2025 homeowner equity report and confirmed something that has not happened in this entire housing cycle. Aggregate US homeowner equity declined by $78.8 billion year-over-year, roughly $8,500 per home. For the first time in this cycle, American homeowner equity is shrinking. Florida homeowners lost an average of $29,400 per borrower. California, $24,700. Arizona, $23,900.

And CoreLogic ran a stress test most channels missed. If US home prices fell just 5% from here, an additional 372,000 homes would flip into negative equity overnight.

We're pulling primary data from the Federal Reserve, the National Association of Realtors, CoreLogic, Adam Data Solutions, and Intercontinental Exchange Mortgage Technology, so you don't have to.

All right, let's keep her going. So, why is Shiller, the man who built the official housing bubble index, warning about stocks instead of houses? Here's the mechanism.

According to the Federal Reserve's Z.1 financial accounts release from Q4 2025, American households now hold 47.1% of their financial assets in stocks. That's the highest share on record, higher than the dot-com peak, higher than 2007. According to the 2025 Gallup poll, 62% of Americans now own stock, matching the highest level since before the 2008 crisis.

Now, here's the academic part, and stay with me because this is the part that connects directly to your home's value. There's a body of Federal Reserve research, including work co-authored by Shiller himself with Karl Case and John Quigley, that measures what economists call the wealth effect. The wealth effect is the rate at which households change their spending when their net worth changes. The research consistently finds that for every dollar of stock market wealth that disappears, consumer spending falls by roughly 3 to 5 cents within the year. That sounds small. It is not small, though. Run the math.

If the S&P 500 corrects 25% and Shiller's forecasting model is signaling something in that range or worse over the next decade, that's roughly 12 trillion dollars of household wealth wiped out. 3 to 5 cents per dollar means 360 to 600 billion dollars of consumer spending vanishing. That's not a recession scenario. That's the recession.

Now, connect it to your house. When consumer spending collapses, employers cut hiring. When hiring slows, would-be buyers postpone. When buyers postpone, inventory builds. When inventory builds in a market already sitting at 4.4 months of supply, prices break. And the homeowners who suddenly need liquidity because they lost a job, because their portfolio cratered, because their adjustable-rate HELOC reset, those homeowners are forced into a frozen market with no buyers. That's the chain. Stock market falls first, consumer spending falls second, employment softens third, housing breaks fourth.

Most housing analysts have it backwards. They think housing crashes first and drags everything down. That's what happened in 2008 because 2008 was a subprime credit event that originated inside the housing market itself. This is a different setup. This time the bubble is in stocks. The transmission runs through your retirement account before it hits your front door.

Now, the historical parallel, because the obvious objection to everything I just said is, "Wait, the dot-com bubble popped in 2000 and housing didn't crash. Housing actually went up." And the reason is, the part that should keep every homeowner awake at night.

In March 2000, the NASDAQ peaked. By October 2002, the S&P 500 was down 49%, but home prices kept rising. Why? Because between January 2001 and June 2003, the Federal Reserve cut the federal funds rate from 6.5% down to 1%. Mortgage rates collapsed, refinancing exploded, and the wealth effect from cheaper housing offset the wealth effect from falling stocks. The Fed bailed out the housing market.

Now, look at the Federal Reserve's position today. The April 29th, 2026 FOMC meeting held the federal funds rate at 3.50 to 3.75% for dissenting votes, the most dissent at a single meeting since 1992. And according to the May 20th release of the meeting minutes, a majority of FOMC participants are openly discussing whether they need to raise rates again because of the energy-driven inflation surge from the Iran conflict. The Powell to Warsh chair transition is happening this summer. The Fed is not in cutting mode. The Fed is in holding mode at best and a hawkish hold at worst.

Here's the controversial take. Wait. It gets worse. Even if the Fed did panic cut tomorrow, the rescue mechanism that saved housing in 2001 doesn't work the same way today. Roughly 78% of all outstanding mortgages in this country are locked in below 6%. Half of them are locked in below 4%. Cutting rates from 3.75% does not unfreeze a market where the median homeowner has a 3.1% mortgage they'll never voluntarily give up. The lock-in effect has neutered the Fed's housing rescue tool. That's the one fact making 2026 more dangerous for homeowners than 2000. In 2000, the Fed had room to bail out housing, and the transmission mechanism worked. In 2026, the Fed has less room, and the transmission is broken.

The man who called both the 2000 stock crash and the 2008 housing crash is now warning about the gap that exists between them. That's the part of the story no other channel is connecting. Tell us in the comments, am I wrong? Are you positioned for stock-led correction that hits housing second, or are you in the camp that says housing breaks first? And if the 1999 parallel landed for you
