Nikkei Stock Average climbed 0.5% to 69086.56 early in the trading day, buoyed by preliminary data showing Japan’s 2Q real GDP grew only 0.3% on‑quarter—below the consensus 0.5% forecast. The weaker figure could prompt the Bank of Japan to hold rates for at least the next month, rather than raising them immediately.

The market reaction was mixed; top performers on the Topix index included the nonferrous metals sector, up 2.9%, and marine transport, adding 1.8%. The dollar traded at 159.14 yen, a slight improvement from 159.30 yen late Friday in New York. Marcel Thieliant, head of Asia‑Pacific at Capital Economics, described the data as a “mixed bag,” noting that while growth lagged, inflationary pressures remained under control.

Analysts suggest that a BOJ pause could support the yen and give the economy breathing room, but investors will watch for signals from the Bank on future policy moves. The positive Nikkei movement reflects investor optimism that the central bank’s dovish stance may keep borrowing costs low, encouraging corporate investment. Meanwhile, analysts caution that the subdued GDP could hint at a slowdown in domestic demand, which might pressure the yen if the BOJ signals a shift toward tightening. Market participants will also monitor upcoming policy statements and inflation data for clues on the BOJ’s next steps.
