The CNN Fear & Greed Index

The CNN Fear & Greed Index plunged to 18 (Extreme Fear) on October 16, down sharply from 45 (Neutral) the previous week, signaling a rapid deterioration in investor sentiment. This marks a 27-point weekly decline and a 47-point drop from the August 14 reading of 65 (Greed). Sentiment weakened steadily through late August and September, with the index remaining in Fear territory for five consecutive weeks before briefly recovering to Neutral on October 9. That rebound proved short-lived, with the latest reading indicating renewed anxiety among investors. Market sentiment has shifted decisively from Greed in August to Extreme Fear in mid-October, reflecting heightened caution and uncertainty.

Third-Quarter Earnings Season: What the Big Banks Will Tell Us About the Economy

Third-quarter earnings season gets underway this week, with JPMorgan Chase, Goldman Sachs, Citigroup, and Wells Fargo reporting on Tuesday, October 13. Bank of America and Morgan Stanley follow on Wednesday, October 14, while U.S. Bancorp and Charles Schwab report Thursday, October 15.

Investors will look beyond headline earnings to assess how higher interest rates, rising Treasury yields, consumer spending, and financial-market activity are affecting the banking industry. Here are five key things to watch.

Net Interest Income in a Higher-Rate Environment

The Federal Reserve raised its benchmark rate by 25 basis points in September, bringing the target range to 3.75%–4.00%, while long-term Treasury yields have climbed to multidecade highs. Higher rates can support banks’ net interest income (NII), but the benefit depends on how quickly loan yields adjust relative to deposit costs and other funding expenses.

Visible Alpha’s estimates call for year-over-year NII growth of 7.7% at Bank of America, 11% at Citigroup, and 5.5% at Wells Fargo. However, the outlook for net interest margins differs: Bank of America is expected to see modest improvement, while Citigroup and Wells Fargo face further margin pressure. Investors should watch actual NII results and management’s updated full-year guidance to determine whether higher rates are translating into sustainable earnings growth.

Trading Revenue and Investment Banking

Capital-markets performance could be a major source of variation among the banks. JPMorgan has projected mid-to-high-teens growth in investment banking fees and trading revenue, while Bank of America expects investment banking fees to decline by at least 10% and sales-and-trading revenue to remain approximately flat.

Credit Quality and Loan-Loss Provisions

Credit quality remains broadly stable, but analysts expect provisions for potential loan losses to normalize from unusually low levels. Rising provisions do not automatically signal financial distress, but unexpected increases—particularly in consumer lending—could indicate that banks are becoming more concerned about borrowers’ ability to repay.

Consumer Health and Loan Demand

Bank earnings can provide a useful window into the condition of the U.S. economy. Wells Fargo has indicated that its 2026 loan growth could exceed its previous forecast and that consumer spending and credit trends remain healthy.

Can Earnings Offset Higher Yields and Inflation?

The broader S&P 500 is expected to deliver approximately 29.5% year-over-year earnings growth in Q3, according to current FactSet-related reporting. Reuters reports that third-quarter earnings for the largest U.S. banks are expected to rise by as much as 20% year over year, although forecasts differ considerably among individual institutions.

In Summary

Bank earnings will offer an important test of financial-sector resilience. Strong NII, stable credit quality, and continued loan growth would be encouraging, but rising funding costs, weaker dealmaking, or deteriorating consumer credit could undermine the outlook.
