Dow sets record and Nikkei tops 70,000 as oil tumbles, but markets pause before the Fed

Global markets sent mixed but largely upbeat signals on Wednesday, June 17, as a steep slide in oil prices and optimism over a US-Iran peace deal propelled some indexes to records, even as investors held back ahead of the Federal Reserve's first decision under new chair Kevin Warsh. The session captured a market caught between powerful tailwinds and the caution that typically precedes a major central-bank event.

On Wall Street the previous day, the divergence was stark. The Dow Jones Industrial Average climbed about 0.6%, or roughly 330 points, to a fresh record near 52,000, notching back-to-back all-time closing highs as cheaper energy lifted shares of fuel-sensitive and consumer-facing companies. The broader S&P 500 moved in the opposite direction, slipping around 0.6% to sit a little over 1% below the record it set earlier in the month, while the tech-heavy Nasdaq fell more sharply as money rotated out of high-flying technology and chip names into more defensive corners of the market. The result was a market split almost evenly between winners and losers.

The dominant force was crude. Oil dropped below $80 a barrel for the first time since early March, extending a multi-session rout fueled by expectations that Washington and Tehran will sign an agreement in Switzerland on Friday, paving the way for the Strait of Hormuz to reopen and Gulf supply to return. Falling fuel costs are a tailwind for airlines, cruise operators, retailers and other businesses sensitive to energy prices, helping explain why the industrial-laden Dow could set a record even as technology dragged on the broader benchmarks.

The standout move came from Japan. The Nikkei 225 punched through the 70,000 mark for the first time in its history during the Asian session, a milestone that took the index to heights unseen since the country's asset bubble of the late 1980s. The rally has been powered by the global artificial-intelligence boom lifting semiconductor shares, heavy foreign buying of Japanese equities and improving corporate earnings, with the easing of Middle East tensions providing the latest spark. The advance came even as the Bank of Japan wrapped up its policy meeting by raising interest rates by a quarter point to 1%, the highest level in more than three decades, a move that complicated the popular yen carry trade and tempered some of the enthusiasm.

In currency markets, the tone was subdued. Asian currencies and the US dollar traded in narrow ranges as investors awaited the Fed's announcement, reluctant to take big positions before learning how the central bank frames the inflation outlook and whether it drops its lingering easing bias. Traders were also parsing the still-emerging details of the Iran truce, mindful that the agreement's terms had yet to be published in full.

The common thread across regions was a market leaning toward optimism, buoyed by the prospect of an end to the war and the relief that cheaper oil brings to inflation, yet unwilling to commit fully until the Fed has spoken. With the US rate decision due later in the day and the Iran signing expected by week's end, investors braced for a stretch in which each headline could swing sentiment. For now, records in the Dow and the Nikkei sat alongside a pause in the S&P 500 and muted currencies, a snapshot of a market that is hopeful but watchful at a pivotal moment.
