ASX Shares Today, Dec 1: Stocks Slip After Surprise Japan Developments

We begin December on shaky ground. On 1 December 2025, the S&P/ASX 200 slipped by 48.90 points, a 0.57% drop,  closing at 8,565.20. Meanwhile, the broader All Ordinaries Index dropped 0.59% to 8,866.40.  We saw two main triggers behind today’s decline. First, a technical glitch at ASX itself disabled its announcements platform, causing trading halts for many firms.
Second, fresh concern after signals from the Bank of Japan that interest rates may rise in Japan. That spooked investors globally and rippled into Australian markets. We will explore how these developments hit ASX today. We break down which sectors and companies were most affected. Then we ask: is this a short‑term wobble, or a sign of deeper trouble?
