S&P 500 Could Hit 3,500 By Year End

“Don't fight the Fed” echoes through the financial media, Wall Street, and in the minds of retail and institutional investors. It pertains to Fed-generated liquidity and is often the sole basis for investors to chase bull markets when the Fed employs easy monetary policy. Unfortunately, some investors forget the phrase is equally meaningful when the Fed is not friendly to markets.

I have developed a model to track Fed liquidity, allowing us to quantify the Fed's influence on the S&P 500.

Before unveiling my liquidity formula and its forecast for the S&P 500, it's essential to discuss the three primary drivers by which the Fed is influencing liquidity: reverse repurchase (RRP), Treasury general account (TGA), and the Fed's balance sheet.

The New York Fed uses numerous repo programs to manage the supply of cash in the banking system, thereby maintaining the Fed funds rate within the FOMC's target range. It is employing its RRP program to accomplish this task. In an RRP transaction, the Fed sells securities to a counterparty and simultaneously agrees to repurchase them at a future date. The duration is often overnight. The transaction temporarily reduces the supply of money from the banking system. Increasing daily RRP balances results in less system liquidity, and a declining balance reduces liquidity.

As shown below, RRP has been around for 20 years but was scarcely used until early 2021. The various pandemic-related rounds of fiscal stimulus and massive Fed liquidity efforts left banks and money market funds with excessive levels of cash. The excess liquidity would have pushed the Fed funds rate lower than the target rate without the RRP program. As such, RRP sucks up liquidity, making Fed funds easier for the Fed to manage.

The Fed has other repo tools, such as repurchase agreements and the standing repo facility that can dampen money market rates by providing the banking system with liquidity.
