BlackRock says $9 trillion in cash is accelerating its return to risk assets, and multiple events this week could amplify market volatility.

According to Huoxun Finance, Rick Rieder, Chief Investment Officer of Global Fixed Income at BlackRock, stated that following the peace agreement between the US and Iran, approximately $8 trillion to $9 trillion in money market funds are rapidly flowing back into risk assets, a process that could have an "explosive" effect. Driven by this, US stocks and bonds rose simultaneously on Monday, while oil prices fell due to expectations of a reopening of the Strait of Hormuz. Rieder noted that liquidity is spreading from low-risk instruments to a wider range of assets, and he expects new Federal Reserve Chairman Kevin Warsh to focus more on balance sheet and monetary supply management rather than solely relying on short-term interest rate tools. This week is packed with events: due to the Juneteenth holiday, the "Triple Witching" day for US stocks has moved to Thursday, coupled with the S&P 500's quarterly rebalancing, increasing volatility risk; SpaceX-related options will resume trading on Tuesday, potentially leading to a gamma squeeze. SpotGamma founder Brent Kochuba warned that the continuous rise in US stocks since April has accumulated hedging pressure on market makers, and if Warsh's first press conference releases unexpected signals, the market's buffer space will be limited. The S&P 500 adjustment took effect after Thursday's close, with Marvell Technology and Flex added, and Pool and Campbell's removed.
