This week’s expert commentary converges on a single concern: financial markets are carrying risks that participants may be underpricing. From hidden leverage and an overheated AI sector to tax policy threatening capital allocation and questions over Federal Reserve independence, senior figures across banking, investment and policy are sounding measured but persistent alarms. At the same time, select investors are moving decisively, acquiring discounted assets and deploying capital where they see value. The gap between caution and action defines the mood heading into August.
