New York Stock Market Pauses After Record, Caught Between Oil Prices and Inflation

On Monday (local time), stocks on Wall Street closed slightly lower just below record highs. The S&P 500 slipped 0.1% to 7,753.11, the Dow Jones Industrial Average fell 0.1% to 53,975.98, and the Nasdaq dropped 0.3% to 26,605.36. What weighed on investor sentiment throughout the session was Brent crude futures surging 5% in a single day to $87.72 per barrel.

Underlying the oil price spike is the closure of the Strait of Hormuz due to the fallout from the war in Iran. With this vital route—through which about one-fifth of global seaborne oil flows—not yet fully restored, political pressure over energy prices and inflation is mounting even within the U.S. political sphere.

The real battleground for markets this week is economic data, especially the July Consumer Price Index (CPI) to be released Wednesday. Wall Street’s consensus is that headline CPI will slow slightly from 3.5% year-over-year to 3.4%. If inflation comes in as expected, it would ease pressure for the Fed to raise rates further, but the 10-year Treasury yield has already climbed from 3.97% before the Iran war in March to 4.70% on the day, meaning the level of interest rates itself remains a burden for equities. Earlier, July’s jobs report—which showed a decline of 23,000 nonfarm payrolls and fell well below market expectations—had already fueled hopes that the Fed’s tightening cycle is nearing its end.

On the corporate side, caution persisted around the notion that “earnings are strong but stocks are expensive.” While S&P 500 constituents are expected to report second-quarter earnings per share (EPS) up roughly 50% year-over-year, much of that has already been priced in. Nevertheless, Berkshire Hathaway surprised with stronger-than-expected results and announced increased deployment of its cash into equities, lifting its stock by 1.5% and providing some support to sentiment. MarineMax and Varex Imaging both surged after being acquired by Blackstone and Teledyne, respectively, whereas Intel fell 4.1% amid dilution concerns after mentioning the possibility of issuing up to $15 billion in new shares.

By sector, energy stocks led the way, with the S&P 500 Energy Index up over 3% on the oil price spike, while transportation stocks, including airlines, underperformed on concerns over fuel costs. For investors, what matters more than this minor index pullback is that news around the Strait of Hormuz and Iran is reigniting oil and inflation expectations, and that the CPI report this week could prompt a recalibration of the Fed’s rate path at its September meeting. Korean investors, in particular, should focus not on short-term volatility but on how oil and U.S. long-term yields will influence future dollar strength and growth-stock valuations.
