Bailey argues valuations of risky assets remain elevated and is worried that a major shock, or multiple simultaneous shocks, could expose financial vulnerabilities. For example, multiple AI firms, cloud providers and chip companies are highly intertwined financially, and this cross-investment could be disastrous in any future corrections.</p><p>The G20 Finance Ministers and Central Bank Governors Meeting is now ongoing – any remedies or responses to the letter are yet to be confirmed.</p><figure class="van-image-figure pull-right inline-layout" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:676px;"><p class="vanilla-image-block" style="padding-top:31.51%;"><img id="diM9tpwF2Lz85R8q85CT78" name="tr-g_news" alt="Google logo on a black background next to text reading 'Click to follow TechRadar'" src="https://cdn.mos.cms.futurecdn.net/diM9tpwF2Lz85R8q85CT78.jpg" mos="" align="right" fullscreen="" width="676" height="213" attribution="" endorsement="" class="pull-rightinline"></p></div></div></figure> </article> ]]>
