Before the Federal Reserve said anything about October, the bond market had already priced a rate-hike scenario. Then the CPI print confirmed the tension that had been building all week.
US producer prices rose sharply in September, and consumer inflation came in hotter than consensus had assumed, keeping the case for tightening alive just as the calendar had cleared the previous expectation of a hold. The ten-year Treasury yield sat near 5.09 percent into the weekend, a level that made the AI capex cycle, corporate debt and mortgage rates all feel the same squeeze.
The sequence matters. In earlier weeks of the same cycle, the market had already removed the October hike from the calendar after the September meeting. The new data forced a repricing in the other direction, with traders pushing October probabilities back into the mid-teens before Chair Kevin Warsh's remarks at the IMF/World Bank meetings in Bangkok pulled them down again.
Warsh highlighted the potential economic impact of AI investment and stopped short of signaling a near-term hike. Traders read the gap between the data and the tone as a buying signal for duration, and the dollar eased on the week as yields cooled from their highs.
The lesson for equity holders: the AI trade and the rate cycle are now the same trade. The Nasdaq's four-week winning streak ended on a 2.1 percent day, and the selloff concentrated in chipmakers whose valuations assume a low-discount-rate world. If the October hike lands, the discount rate moves first. Everything else follows.
