AI credit stress became the macro trade
The week's defining force was not the hot inflation print or the Houthi missile; it was the moment AI's financing cost became a macro variable. Long-end yields spent the week near multi-decade highs, with a WSJ survey seeing the 10-year Treasury at 5.1% by year-end and Fed officials keeping hike odds alive. Then September CPI and PPI ran hot, but Friday's AI-debt selloff pulled the 10-year UST back to 5.04% after nearing 5.32%, dragged Bunds lower, and handed the dollar its worst day in over a month. The same credit stress that threatens AI-capex borrowers is now a haven bid for sovereign duration. Meanwhile the Hormuz/diesel shock and Europe's fiscal budgets remain separate inflation and supply tests. The PM's next question: does AI credit reprice further, or does sovereign haven demand keep long yields capped despite inflation?
