Separately, Barclays President has warned that financial markets are failing to adequately price in the risks of potential energy shocks. The warning comes as global energy markets continue to face volatility and geopolitical uncertainties that could impact broader economic stability.

Meanwhile, prediction market platform Kalshi has received regulatory approval to offer margin trading services as it seeks to attract more institutional clients from Wall Street. The approval represents a significant expansion of the platform's capabilities and could increase its appeal to professional traders and financial institutions.

The developments highlight divergent views within the financial sector about current market positioning and risk assessment. While some firms are advising caution on short positions, others are expanding trading capabilities to capture institutional interest in alternative markets.

These mixed signals from major financial institutions come as markets navigate ongoing economic uncertainties and regulatory changes affecting trading platforms and investment strategies.
