📝 Executive Summary
The US long-bond market is emitting a 2008-style recession signal, with 30-year Treasury yields crashing to their lowest since mid-2024. The move triggered a broad risk-off session, dragging the S&P 500 down 1.5% and pushing the VIX fear gauge above 20. Investors piled into safe havens, lifting the dollar and long-duration ETFs like TLT, echoing pre-crisis dynamics.
