The minutes before something breaks on a trading floor are marked by a certain kind of silence. Silence isn’t actually silence, as anyone who has strolled through the lower Manhattan canyons in the late afternoon, past the bronze bull and the ring of barricades, will attest. Instead, it’s the murmur of brokers leaning over keyboards, the hum of screens, and a sort of held breath. That sound has returned. Not too loud yet. However, there.
The well-known metric used by Warren Buffett to compare the total value of US stocks to the nation’s economic output has risen to about 227%. The number itself is easy to scan, reading like a footnote. More than 20 years ago, Buffett wrote in Fortune that anything close to 200% indicated investors were “playing with fire.” The current reading is significantly higher than that. Both a sense that traders are aware of this and a stronger sense that they have chosen to act as though they are unaware of it are present.

The bulls are prepared with their response. They claim that profits are increasing more quickly than the overall economy and that the premium is justified by the new technological cycle, which includes chips, automation, and the never-ending growth of cloud infrastructure. It is feasible. However, corporate profits are currently well above the long-term range of 7 to 8% of GDP, at about 12%. Similar to how moths are drawn to warm light, margins like these tend to draw competitors. Milton Friedman cautioned that earnings cannot continue to surpass national income indefinitely, as Buffett himself liked to remember. They have never done so.
It’s difficult not to think of other instances that felt equally meaningless as you watch this play out. The same indicator reached about 200% in the spring of 2000, and the dot-com economy was slowly collapsing in public humiliation within months. Another peak was reached in November 2021, and then there was a 19% decline. It’s not always a single dramatic day that reveals the pattern. Sometimes it’s a slow leak, a string of unpleasant afternoons until no one is impressed by the chart.
The external shocks come next. Crude prices have recently risen by almost 18% due to the Iranian conflict, and the Strait of Hormuz is back in every analyst’s morning report. The rupee fell to 94.25 against the dollar, and the Sensex lost about 1,000 points in a single session in India, a country that imports more than 80% of its oil. The so-called fear gauge, the India VIX, increased by 15% in just one week. This isn’t exactly a crash. However, none of it is serene either.
Here, history provides us with a helpful rhythm. The Dow had risen six times in eight years prior to the 1929 collapse, and a number of economists had declared that prices had reached a “permanently high plateau.” After months of bullish certainty, Black Monday in 1987 erased 22.6% in a single day. The unraveling in 2008 had a different form but the same essence: too much faith, too much leverage, and too few questions. The warnings were always visible in advance. They were consistently largely disregarded, the kind of oversight that is documented in central bank records and historical financial archives, which continue to be dryly factual long after the panic subsides.
The collective posture, rather than any one number, is what makes the present moment unsettling. It appears that investors think volatility is something that happens to other people in different decades. They might be correct for a quarter or two more. They might not be. Buffett’s argument was never that he could foresee the exact moment, but rather that gravity eventually takes over. And when it does, those who are affected seldom anticipate it in the same way. All they hear is the hum cease.
