Dow Closes at Record High Amid Yen Slump and US-Japan FX Market Moves

Market Overview and Key Developments

By Jamie McGeever

ORLANDO, Florida, Aug 3 (Reuters) - U.S. stocks rallied strongly and the Dow notched a record-high close on Monday, boosted by solid manufacturing data and optimism around earnings and U.S.-Iran peace hopes, while the yen slumped to a three-month low after a historic bout of coordinated U.S.-Japanese intervention.

In my column today, I look at the U.S. Treasury's activity in the FX market buying Japanese yen. Treasury's goals may have been conventional, but its methods weren't, and the timing may also speak to deeper concerns about the U.S. bond market.

Today's Talking Points

Spend to Defend: Japan's Yen Intervention

Japan is estimated to have spent almost $100 billion over a 48-hour period last week in FX intervention to support the yen — $36.6 billion on Friday, and $59 billion on Thursday. This follows a $73 billion spree in April-May this year, $36.8 billion in July 2024, $62.2 billion in April-May 2024, and $42.8 billion in October 2022.

Added together, Japan has spent around $310 billion over the past four years defending its currency. Has it worked? That's subjective. Absent that demand, the yen may well have sunk a lot lower than the 40-year low 164 per dollar recently. But we'll never know. That's a lot of dollars, and a chunk of it will have come from repo and other funding routes. But if it has prevented a much weaker and more volatile currency, Tokyo may see it as money well spent.

Bouncebackability: Wall Street's Resilience

The word "bouncebackability," popularized in British football parlance, describes a player or team's powers of resilience and penchant for overcoming often multiple setbacks. Wall Street is showing those characteristics, in spades, with the S&P 500 on Monday rebounding to within 0.5% of its record high and the Dow notching a fresh record-high close.

Investors are putting the recent chip rout to one side, and are taking their cue from the earnings picture, which could hardly be more bullish. The LSEG I/B/E/S Q2 annual consensus U.S. earnings growth forecast is now running at an astonishing 47.7%, virtually double what it was only a month ago.

Factory Whirl: Global Manufacturing Trends

Investors have had a few financial market wobbles to worry about recently: South Korean stocks, the global chip sector more broadly, the yen, and long-dated bonds, to name a few. But when it comes to the real economy, things have been much less volatile. If there's any background noise, it's the sound of global factories purring along rather nicely.

The latest purchasing managers index data show U.S. factory activity expanded in July at its fastest pace in over four years, euro zone output was the highest in four and a half years, and Japan's manufacturing PMI leaped to a 12-year high. There are weak spots, of course — China, India, UK — but overall, the AI capex boom is helping to keep the world's manufacturers and producers busy.

  • U.S. manufacturing activity had recently topped a four‑year high, although input prices remain elevated, supporting the positive market tone (ca.investing.com).
  • A rare, coordinated yen‑buying intervention occurred as the U.S. Treasury acted alongside Japan—reportedly selling euros to buy yen—to stabilize the currency, contributing to the yen’s rebound from multidecade lows (axios.com).
