Taiwan's market is on a tear, adding more than 1,600 points in two days, which is good news for local investors but has the central bank worried about people borrowing to chase the rally.

• The Taiwan index closed up 663 points near 45,833, with foreign money pouring in and TSMC, Foxconn, Delta and MediaTek all higher.
• Nvidia's results first knocked the stock down on weak profit margins, then sent it up over 4% after it guided to much faster revenue growth than Wall Street expected.
• US inflation came in hotter than expected and the economy held up better than first thought, so traders now fully expect a Fed rate hike by year-end.
• Taiwan's central bank warned that people are putting borrowed money into stocks, and the exchange is tightening rules on investors who fail to settle trades.
• US stocks barely moved, oil fell, and government bond yields ticked up to 4.65%.

Outlook: Attention turns to Fed chair Warsh's Jackson Hole speech for clues on rates, with Taiwan's rally at risk if borrowed money keeps piling in.
