The Rhyme: Rate Hike Odds Spike With Stocks at the Peak & Its 2018 Echo

"History doesn't repeat… but it rhymes." — Mark Twain

The probability of a Federal Reserve rate hike at the September 15-16 FOMC meeting jumped to 66% this morning, up from 40% a week ago, after Kevin Warsh's hawkish Jackson Hole speech and five straight days of climbing Treasury yields. The 10-year note touched 4.80%, its highest level since January 2025, while WTI crude held above $86 and Brent pushed toward $94 on the Iran conflict. The S&P 500 sat at 7,646.80, nearly 2% below its August 13 all-time closing high of 7,798.99, barely noticing that the labor market printed a negative payrolls number in July for the first time since the pandemic. The last time a Fed chair hiked rates with the S&P within striking distance of its record was September 26, 2018.

S&P 500: 7,646.80 (−0.61%)  |  10yr: 4.80%  |  WTI: $86.57  |  Fed funds: 3.50−3.75%  |  Sept hike odds: 66%  |  VIX: 15.86

Jerome Powell had been Fed chairman for less than eight months. He still had the careful posture of a man who knew the cameras were watching everything he did, and on the afternoon of September 26, 2018, he stood at the podium in the Federal Reserve's boardroom and announced the third rate hike of his tenure, lifting the fed funds target to 2.0-2.25%. The vote was unanimous. Nobody dissented. The S&P 500 had closed at an all-time record of 2,930.75 six days earlier, and the economy had just posted 201,000 new jobs in August with wages growing 2.9% year over year, the fastest pace since the recovery began. There was no obvious reason to worry.

Two days before the hike, on September 24, the Trump administration imposed 10% tariffs on $200 billion worth of Chinese goods, with escalation to 25% scheduled for January. Oil was climbing, too. WTI crude had crossed $70 and was heading for a peak of $76.40 on October 3. Brent was running even hotter, pushing toward $86. But the tariffs and the oil were treated as manageable friction, not structural risk. Stocks held their highs. The VIX sat near 12, a level that said the market believed nothing bad could happen for a very long time.

Then Powell went on PBS on October 3 and gave an interview with Judy Woodruff. She asked about interest rates, and Powell answered with a line that would echo through the next three months of American finance: "We're a long way from neutral at this point, probably." Seven words. That was all it took. The 10-year Treasury yield was already above 3.2%, its highest in seven years, and Powell had just told the world that rates had a lot further to climb. The bond market believed him. The stock market believed him too, and it started selling.

What followed was one of the most violent quarter-end collapses in modern memory. The S&P fell through October, bounced weakly in November, then cratered again after the Fed hiked a fourth time on December 19, taking rates to 2.25-2.50%. By Christmas Eve, the index had dropped to 2,351, down nearly 20% from its September high. Oil crashed from $76 to $42 in the same window, erasing a year's worth of gains in ten weeks. The VIX, which had sat at 12 when everything was fine, spiked above 36.

It took eleven days into the new year for Powell to fix it. On January 4, 2019, he appeared at the American Economic Association's annual meeting and said the Fed could be "patient" on further hikes. That single word reversed the entire trade. Stocks rallied. Yields dropped. The hiking cycle was over. But the damage was done, and the people who had been long at the September peak never forgot how quickly things turned.

Both times: a new Fed chair, stocks at record altitude, tariffs in the headlines, oil climbing, yields rising, and a September hike on the calendar. The setup is nearly identical. The question is whether the ending is too.

The S&P 500 had already reached its all-time intraday high of 2,940.91 on September 21, 2018, five days before the hike. After Powell raised rates on September 26, the index held for about a week. Then the selling started, quietly at first, picking up speed after the PBS interview on October 3. By October 10, the index had dropped 5%. By October 29, it was down more than 10%. The market stabilized briefly in November, but the December 19 hike — which came even as stocks were already reeling — triggered the final leg down. Christmas Eve was the bottom, with the S&P at 2,351, a round-trip that erased every gain since April 2017.

The smart money in late September 2018 wasn't the crowd that shorted stocks outright. It was the people who noticed the VIX at 12 and bought cheap downside protection — put options three months out — on the assumption that if the Fed meant what it said, volatility would reprice violently. Those positions paid off five, ten, even twenty times over by Christmas. The key was the timing: the insurance was cheapest exactly when the market was most certain that nothing bad would happen.

The 2026 setup carries the same structure but with worse inputs. Warsh is staring at 66% hike odds, not a done deal, and Friday's August nonfarm payrolls report is the last major data point before the FOMC blackout begins. Consensus is 58,000 jobs. If that number comes in negative again — a second miss in three months — the hike odds could collapse overnight and take yields with them. But if it comes in strong, the hike locks in, and the question becomes whether Warsh has a "long way from neutral" moment of his own at the post-meeting press conference on September 16.

In 2018, the peak-to-trough damage took 65 trading days. The reversal took one word: patient. The entire Q4 2018 crash was caused by a Fed that hiked into a market that couldn't absorb it, then fixed the problem only after the damage was done. The question for the next two weeks is whether Warsh will read the same playbook and skip to the last chapter, or whether he'll have to learn the lesson the same way Powell did.

The edge: In 2018, downside protection was at its cheapest the week before the September hike, when the VIX sat at 12 and the S&P was at its all-time high. Today the VIX is 15.86 and the S&P is about 2% below its record. If Friday's jobs number is strong enough to lock in the hike, the window for cheap insurance closes fast. If it's weak enough to kill the hike, yields drop and rate-sensitive names get repriced upward. Either way, Friday is the pivot point, and by Monday the trade will already be crowded.

The ISM Services PMI lands Thursday morning. If the prices-paid component stays hot while the employment sub-index softens, it recreates the exact same split the Fed saw in October 2000, when a strong services sector masked a manufacturing contraction that had already begun pulling the economy toward recession — and the FOMC held at 6.5% for three months too long.
