Wall Street indices closed higher on Tuesday, driven by better-than-expected quarterly results from several of the largest US banks.

The positive earnings reports provided a fresh catalyst for equities, which have been buoyed by a recent sequence of disinflationary data releases.

Investors interpreted the strong financial performance as evidence that the banking sector remains robust despite ongoing economic uncertainty.

The rally extended a multi-day upward trend that began following a benign US producer price index (PPI) report.

That earlier data point had already eased concerns about persistent inflation, leading markets to price in a more dovish stance from the Federal Reserve.

The combination of cooling price pressures and resilient corporate profits has created a favorable backdrop for risk assets, with financial stocks leading the charge.
