JP Morgan Leads Bank Earnings, TSMC Highlights AI Trade

Earnings season for the fourth quarter of 2025 effectively starts Tuesday with the year-end report from JP Morgan Chase, the U.S.’s largest bank, which said last week that it would become the next issuer of the Apple Card. Banks in the prior quarter reported solid results across the board, with analysts saying they were poised to see more improvement to close out the year.

Despite the positive results last quarter, JP Morgan CEO Jamie Dimon warned that the U.S. economy was facing continued uncertainty. Wells Fargo, which said that it could see slower growth in its net interest income for the year, reports Wednesday. The nation’s oldest bank, BNY Mellon, and investment banking giant Goldman Sachs are also reporting.

Taiwan Semiconductor earnings will show whether chipmakers can continue to drive strong revenue growth amid surging demand for artificial intelligence chips. Delta Air Lines earnings will shine a light on travel after airlines experienced disruptions during the government shutdown last year, potentially slowing the recovery after a slow spring.

Inflation Data Comes Amid Interest-Rate Uncertainty

Inflation data is due Tuesday with the release of December’s Consumer Price Index, which showed price pressures slowing to 2.7% in its prior report. A delayed report from October and November on wholesale inflation could further show how pricing changes are impacting the economy.

The data will be eyed by Federal Reserve officials, who are divided over whether to cut interest rates at the central bank’s next meeting in late January. Several Fed officials are scheduled to speak this week, potentially providing signals regarding the Fed’s direction.

Retail sales data for November will provide insight into the 2025 holiday shopping season, as consumer activity continues to help power the U.S. economy. Delayed new home sales reports for September and October are among the housing-data reports expected as home sales have stalled amid persistent affordability challenges. The budget deficit report will provide an update on tariff collection levels.
