Markets just flipped the script on Kevin Warsh's Fed: Chart of the Day

Only two weeks ago, Fed Chairman Kevin Warsh claimed markets had been a significant part of the Fed's tightening efforts. However, Wall Street has now reversed that trend and more. A Bloomberg gauge of US market conditions spiked to its simplest level since 1996, marking a remarkable turnaround from late July. Financial conditions refer to how easy or difficult markets make it for investors to take risks and raise capital.

Rising stocks, stable markets, and cheaper corporate borrowing indicate easier conditions. Conversely, falling stocks and higher borrowing costs signify tighter conditions. The index in the chart specifically focuses on these market signals, suggesting Wall Street is unusually loose. Between Warsh's first Fed meeting on June 17 and his next on July 29, Treasury yields increased, stocks declined, volatility surged, and corporate borrowing became more expensive.

The Fed left its benchmark rate unchanged at 3.5% to 3.75%, but markets tightened around it. Since July 29, the S&P 500 has risen nearly 7%, the VIX volatility gauge has fallen six points to yearly lows, and junk-bond borrowing costs have dropped. Despite the Fed's rate remaining constant, Wall Street's appetite for risk is evident across various markets, including Cathie Wood's ARK Innovation ETF and IPOs.

This shift isn't due to a drop in long-term interest rates, which have actually risen since Warsh's first meeting. The Fed has maintained its stance, yet the market conditions measure has surged to a 30-year high. Risk-free money remains expensive, but Wall Street has made risk-taking cheaper nonetheless. This could pose challenges for Warsh's mandate.

If stocks continue to climb, volatility stays low, and borrowing costs keep falling, the market might further stimulate an economy the Fed aims to cool. This highlights a broader point: the Fed controls a key short-term interest rate, but markets can either assist or obstruct policymakers. The stronger Wall Street performs, the less aid Warsh receives, and the greater the Fed's workload becomes.

Warsh has acknowledged this signal, stating that the Fed's rate isn't static but rather the start of a larger narrative.
