Summary

Financial gauges signal near-crash conditions, with geopolitics at risky levels.

US-Iran diplomacy and UK debt warnings are key geopolitical drivers.

These factors suggest heightened market volatility and potential divergence.

Geopolitical drivers

  2. US-UK Sovereign Debt Warnings60Warnings over surging debt servicing costs directly pressure sovereign bond yields, weighing heavily on broader credit/risk sentiment.
  3. Allied Split on Middle East Policy54Western discord over Palestinian recognition increases diplomatic frictions with Israel, elevating the risk of secondary sanctions/trade disruption.
