"History doesn't repeat… but it rhymes." — Mark Twain
◉ THE PRESENT
Japan's Nikkei 225 ripped past 65,000 for the first time in history Monday morning, climbing 1,915 points in a single session as Tokyo traders piled in on word the Strait of Hormuz might reopen. The three-day move now stands at 8.95%, the steepest sprint the index has run in more than six years. American markets sat closed for Memorial Day, so Tokyo did the work alone, and it did it on relief that an oil shock might be ending before it cracked global growth.
Nikkei intraday high 65,408 | +8.95% in 3 sessions | Steepest 3-day gain since 2020
The last time Tokyo felt like this, the calendar said December 1989. Nothing could stop it. Until something did.
◉ THE ECHO — DECEMBER 29, 1989
The last day the rally lasted.
Snow was falling on Otemachi when the closing bell rang at the Tokyo Stock Exchange on December 29, 1989. The Nikkei finished at 38,915.87, up 29% on the year. Traders at the big four — Nomura, Daiwa, Yamaichi, Nikko — popped champagne in the corner offices and called it a coronation. Tokyo had passed New York as the largest stock market on earth. The land under the Imperial Palace, a few blocks from the exchange, was supposedly worth more than the entire state of California. A salaryman with a modest apartment in Setagaya was a paper millionaire. Nobody in the room saw it ending. Nobody at all.
The four trading houses had spent the year selling clients on something called the tokkin account — discretionary money pools that invested in zaitech, financial engineering, the alchemy of corporate Japan turning factory profits into stock gains. Toyota was making cars. Toyota was also running what was effectively a hedge fund. So was Sharp. So was every major industrial in the country. They were all long the same thing. They were all long themselves.
Twelve days earlier, on December 17, a new man had taken the elevator up to the eleventh floor of the Bank of Japan's stone headquarters in Nihonbashi. Yasushi Mieno had spent the prior five years as deputy governor watching the bubble inflate from inside the institution that fed it. He didn't believe in it. He never had. On Christmas Day, four days into the job, Mieno surprised the market by lifting the official discount rate from 3.75% to 4.25% — the fourth hike of the year. The brokers shrugged. The Nikkei closed at a record four trading days later.
That's the part everyone forgets. The catalyst for the top was not bad news. It was hope. The last thousand points came on optimism that the Cold War was ending. The Berlin Wall had come down six weeks earlier. The Soviets were pulling back from eastern Europe. Japan was ascendant, a peaceful superpower built on cars and chips and savings, and the world was finally safe. Buying stocks felt patriotic. It felt obvious. It felt like the only thing to do.
Mieno wasn't shrugging. He was loading. By August 1990 the discount rate would be 6%. By then the Nikkei would already be down 40%.
◉ THE RHYME — WHAT'S IDENTICAL
When the same country reaches the same euphoria on the same kind of news, the math doesn't care that thirty-seven years passed in between.
◉ THE DIVERGENCE — WHAT'S DIFFERENT THIS TIME
The chart looks the same. The plumbing underneath is not.
The valuation gap. In December 1989 the Nikkei traded near 70 times earnings. Today it trades around 22. The euphoria looks similar on the screen. The price you're paying for it is in a different universe, and that's the single biggest reason this rally has more room than the last one did before it ran out.
The yen position. In 1989 the yen was strong and getting stronger off the Plaza Accord. Today the yen sits near 158 to the dollar — its weakest in nearly four decades. A big chunk of foreign money in Tokyo right now is there partly because a yen rebound itself would juice dollar returns. That's a different kind of trade, and it unwinds differently.
Who actually owns the stocks. In 1989 the Nikkei was overwhelmingly held by Japanese banks and corporates locked together through cross-shareholdings. Today over 30% of the float sits with foreign investors. When this turns, it doesn't unwind through patient Tokyo banks. It unwinds through hedge funds in Singapore and London and Greenwich, all hitting the bid at the same time.
The policy chamber. Mieno walked into the BOJ in 1989 with the discount rate at 3.75% and a clear runway to hike. Governor Ueda walks in this Monday morning coming off seventeen years of negative rates and quantitative easing, with the BOJ's balance sheet still north of GDP. If this rally cracks, there is no rate cut to throw at it. The medicine has already been swallowed.
◉ THE RECKONING — WHAT HAPPENS NEXT
The Tokyo exchange opened the new decade on January 4, 1990 at 38,712. By the end of that month the Nikkei was at 37,189. By April it had broken 30,000 going the other way. By October — ten months after the champagne — the index sat at 20,221. Half gone. In ten months.
Mieno kept hiking. The discount rate went to 5.25% in March, then 6% in August. He later admitted he had been trying to break the bubble all along. "Asset prices," he said in a 1991 lecture, "are too important to leave to the market." It was the sentence he had been waiting to say for a decade.
The Tokyo property market followed the stocks down. Land prices fell roughly 80% over the next dozen years. The big four trading houses — the ones popping champagne on December 29, 1989 — did not all survive. Yamaichi collapsed in 1997. The big banks were quietly insolvent for years and had to be propped up with public money. The Nikkei would not see 38,915 again for thirty-four years.
What the smart money did is not a secret. Stanley Druckenmiller and George Soros were short the Nikkei into January 1990. Paul Tudor Jones had been warning about it in his year-end letters. Edward Chancellor cataloged the trades a decade later in Devil Take the Hindmost. None of them knew exactly when the top would come. They didn't need to. They knew that 70 times earnings, land worth four times global GDP, and a brand new central banker who hated the bubble could not coexist for long.
Map that to right now. The Nikkei is not as stretched on valuation as it was in 1989. It is, however, behaving exactly the same way on sentiment. A three-day melt-up of nearly 9% on a single piece of geopolitical relief tells you positioning got crowded fast. Crowded positioning is the precondition for what comes next. When everyone is on the same side of the boat, the question stops being if and starts being when.
Tops in Tokyo don't ring a bell. They ring on hope. The last one rang on the end of the Cold War. This one is ringing on the end of an oil shock. The catalyst that kills a rally is almost always the one nobody thought to watch.
◉ TOMORROW’S WATCH
Watch the Bank of Japan's June 16 policy meeting. Governor Ueda is under quiet pressure to lift the policy rate another quarter point as the yen pushes through 158 and food inflation runs hot. The last time a new BOJ regime moved on prices in its first months in office, the man behind the desk was Yasushi Mieno, and the date he chose was Christmas Day 1989.
