Q2 Bank Earnings Preview: A Dimmer Light?

First-quarter financials earnings growth finished mid-pack, and the second quarter doesn't look much brighter for this influential sector. In fact, it could dim, setting the stage for an earnings season with lots to prove.

Big banks like JPMorgan Chase (JPM), Bank of America (BAC), and Goldman Sachs (GS) tend to report bright and early positive surprises quarter after quarter, often helping improve market sentiment before other sectors get out of bed. They might do that again when they and other banks report Tuesday and Wednesday, considering a favorable trend in the yield curve that could improve profit margins.

Overall, though, analysts expect second-quarter S&P 500 financials sector earnings to grow just 2.9%, well below the 5.5% they penciled in back on March 31 and short of 7.1% first-quarter growth, according to the latest FactSet report. The financials sector includes many smaller banks, brokerages, insurance companies, and payment firms, so it shouldn't be painted with one brush. Big banks have an advantage and typically get the lion's share of attention. Recent signs of life in initial public offerings (IPOs) and market volatility that likely helped support trading volume could both work in the banks' favor even if the overall financials sector doesn't impress.

Headwinds for banks include consumer and corporate reticence amid signs of slowing economic activity. In addition, tariff-related inflation concerns, a worsening U.S. fiscal outlook, a lackluster housing market, relatively high borrowing costs, weaker consumer credit, and geopolitical turbulence are sore spots. The IPO and M&A markets flashed some life in June but remain well below peaks of a few years ago, and banks face increasing competition from private markets for services they once provided.

Investors might also want the latest word on credit availability, a key factor driving the economy. Corporate credit spreads—which measure the expense of borrowing money—have been relatively stable and low over the last few months despite the ups and downs of the stock and Treasury markets. If banks and other lenders sense a declining economy, they grow more reluctant to lend, and the spread between corporate bond yields and the U.S. 10-year Treasury note yield can climb, making it more expensive and less desirable to borrow.

However, that's the opposite of what's happening. High-yield spreads dropped 150 basis points by late June from early April.
