Undoubtedly, the S&P 500 Futures had signaled an advent of a steep fall on July 16, 2021 that was accompanied by a sharp surge in the S&P Volatility Index.
On Monday, this first signal was confirmed by a steep fall in US equity markets. At 4:30 pm (GMT), the Dow was trading 781 points lower, the S&P 500 had lost more than 78 points and NASDAQ was below 165 points. This type of steep fall could create big jolts in global markets, until the Fed’s next meeting on July 28, 2021. Undoubtedly, based on the reactionary moves of the US equity indices, we hardly need to wait for the Fed’s next meeting.
Globally, Central Banks are having difficulty adjusting their monetary policies amid the sudden surge in the COVID-19 cases, particularly at when most countries were planning to push forward reopening, following completion of vaccinations. But the abrupt upswing in COVID-19 cases has left the hopes of earlier re-openings on hold.
The current steep fall of US equity indices seems to be the impact of ill-tempered exchanges between the Biden administration and social media giants, which illustrated the mounting concern in Washington about the spread of the Delta variant of COVID-19, which is more than twice as contagious as earlier strains of the virus.
Infection rates are rising particularly strongly in the South and Midwest, where skepticism toward vaccines—and to most policies advanced by the Democratic administration—is highest.
The Federal Reserve seems to follow the conventional methods to tackle growing inflation by keeping interest rates below zero or even in the negative territory. In short, this indicates that Fed Chair Jerome Powell’s insistence that inflation is transitory is becoming less defensible. Even if these high readings abate as the base effect of depressing prices a year ago fades, to call a mismatch between supply and demand that could last many months transitory begs the question.
Central bank policymakers in other countries are less hesitant. The Bank of Canada cut its bond purchases by C$1 billion a week in April, to C$3 billion (USD$2.4 billion), and last week said it will cut a further C$1 billion (USD$784 million) a week.
Finally, global equity markets could hardly wait for the Fed's next meeting on July 28, which is expected to hardly come with a decisive move to control inflation. And, with the absence of a solid monetary policy, big bears could be attracted to remain in control of global equity markets.
