Key Takeaways

1.Enterprise AI is decentralizing toward on-premises Small Language Models (SLMs), threatening massive hyperscaler data center capex with the risk of becoming stranded assets as Anthropic server utilization has fallen 26% since January 2026.
2.India's structural growth story remains intact driven by renewable electrification/solar, manufacturing expansion, and private capex recovery, counterbalancing AI displacement fears in IT services.
3.The Fed's mini-tightening cycle and rising US 10-year Treasury yields above 5% create headwinds for long-duration US equities, while foreign central banks, notably China and Japan, continue trimming Treasury holdings.
