BlackRock’s Rieder Sees ‘Explosive’ Rally as Cash Gets Unlocked
BlackRock’s Rick Rieder says the surge in US stocks after Trump’s Iran peace deal reflects investors redeploying the roughly $8-9 trillion held in money market funds, potentially fueling an explosive rally.

BlackRock’s Rick Rieder said the surge in US equities following President Donald Trump’s Iran peace deal announcement reflects investors starting to redeploy the roughly $8 trillion to $9 trillion held in money market funds, potentially fueling an explosive rally.
The chief investment officer of global fixed income at BlackRock noted that the massive cash pile, which has been sitting on the sidelines amid geopolitical uncertainty, is now being unlocked as risk sentiment improves. The Iran peace deal, announced earlier this week, has reduced safe-haven demand and prompted a rotation into equities. Live stock prices and charts on NowPrice show the S&P 500 and Nasdaq reacting positively, with broad-based gains across sectors.
For stock market traders, the potential redeployment of such a large cash reserve is significant. Historically, when money market fund assets decline, equities tend to benefit from increased liquidity and buying pressure. The so-called 'wall of worry' may be giving way to a 'wall of cash' that could support further upside. However, the pace of the rally will depend on how quickly investors shift from cash to risk assets, and whether other macro factors, such as inflation data or Fed policy, remain supportive.
Looking ahead, market participants will watch for further confirmation of the peace deal’s implementation and any additional fiscal or monetary policy responses. Key data releases, including consumer confidence and manufacturing PMIs, will provide clues on economic momentum. If the cash rotation continues, the current rally could extend, but traders should remain alert to potential volatility if geopolitical tensions resurface or if valuations become stretched.
