Nikkei Falls for Fourth Day as Stronger Yen and Rate Uncertainty Weigh

Tokyo stocks experienced a mixed performance on September 3, with the Nikkei 225 ending at 64,214.48, down 111.16 points due to uncertainty surrounding interest rates and currency fluctuations. The broader TOPIX rose 0.5% to 4,102.04. The Nikkei fell for the fourth consecutive day and posted its lowest close in about a month. Initially, the index rose after Wall Street's overnight gain but later lost direction as investors grappled with a stronger yen, Bank of Japan's rate-hike expectations, falling energy shares, and renewed caution towards artificial intelligence and semiconductor-related stocks.

Prime Market trading value totaled around 7.5770 trillion yen, just below the 10 trillion yen mark that characterized earlier summer sessions. Trading volume stood at approximately 2.18832 billion shares. Market breadth was mildly positive, with 805 stocks advancing, 685 declining, and 65 remaining unchanged, indicating a stronger overall market than the Nikkei's decline suggested.

The Nikkei briefly dropped as low as 63,772.80, briefly crossing the 64,000 level for the first time since early August before recovering part of the loss into the close. Despite the rebound from the day's low, the index failed to regain positive territory. Market commentary focused on the market's struggle for direction amidst unresolved macro risks.

The first risk was currency volatility, as the yen strengthened sharply, reaching around 156.71 per dollar. This followed hawkish remarks from Bank of Japan board member Hajime Takata, who suggested the central bank should raise rates swiftly to prevent inflation from spiraling out of control. The yen's rise affected sentiment towards some manufacturing and export-linked stocks, as it reduced the value of overseas earnings.

Moreover, the yen's movement sparked debate over whether Japan's currency was now more influenced by Bank of Japan expectations than by intervention risk. The second risk was the bond market. Japan's 10-year government bond yield had touched 3% earlier in the week, marking a significant psychological shift after decades of ultra-low rates.

On September 3, bond markets showed some relief, with longer-dated Japanese yields easing after a 30-year bond auction drew decent demand. However, higher yields remained challenging for technology and growth shares, raising the discount rate applied to future earnings and making investors less inclined to pay high multiples for such companies.

The third risk was oil. Crude prices briefly eased after their previous surge, but energy markets remained volatile due to the U.S.-Iran standoff and concerns over shipping routes. Japan, being a major importer of energy, faced inflation risks from higher oil prices. Energy shares were among the weakest parts of the market, with Japan's energy explorer sector falling 3.26%, with Inpex falling about 4% and Yokogawa Electric also experiencing sharp declines.

Technology and AI-related shares were mixed, with some stocks rising while others fell following the geopolitical risk shift following the oil price drop.
