US benchmark equity indexes ended lower Tuesday as traders parsed the latest trade deficit report with an eye on the Federal Reserve's monetary policy meeting.

* The US goods and services trade deficit widened 14% to $140.5 billion in March, the Census Bureau and the Bureau of Economic Analysis reported. The consensus in a survey compiled by Bloomberg was for a deficit of $137.2 billion.

The deficit reading represents a record level as companies "rushed" to import goods ahead of the Trump administration's planned tariffs, Stifel said in a note to clients.

* The Fed is scheduled to announce its latest interest rate decision Wednesday. Markets widely expect policymakers to leave rates unchanged, according to the CME FedWatch tool.

* June West Texas Intermediate crude oil closed up $1.87 to settle at $59 a barrel, while July Brent crude, the global benchmark, was last seen up $1.82 to $62.05. The Energy Information Administration said it expects the oil market to weaken this year on slowing economic growth and rising inventories.

* Constellation Energy (CEG) shares jumped 10% after the company logged better-than-expected Q1 operating revenue and affirmed its full-year adjusted operating earnings outlook.
