A what‑if from the future

What if coordinated undersea-cable cuts sever the global internet?

Coordinated cable cuts are a connectivity/operational-risk shock: VIX bids, high-beta tech and crypto sell on settlement/messaging fear, and gold catches a reflexive geopolitical haven bid. Behavioral analogue is the 2024 Red Sea / Baltic cable incidents and the June-2025 geopolitical vol spike — sharp but quickly faded once rerouting was confirmed. Forward angle: the financial system's SWIFT/clearing redundancy means the equity hit is more sentiment than substance; the durable trade is in subsea-repair and satellite-backup names, not a broad index short.

What it would mean

If this plays out, it is a risk-off shock. Coordinated undersea-cable cuts disrupt global internet and financial messaging. The trigger decomposes into signed root‑shocks — Risk appetite ▼ · Geopolitical risk ▲ — which propagate through our causal graph to the markets below.
