Without any significant market-moving triggers on Wednesday, the greenback declined against the euro and the yen as investors anticipated the release of the U.S. inflation figures scheduled on Tuesday and the Federal Reserve's interest rate trajectory the day after.

Although Fed fund futures traders are pricing in another rate increase in July, the U.S. central bank is expected to maintain rates constant as it assesses the effects of recent rate hikes.

On Tuesday, consumer inflation data is anticipated to reveal that prices increased by 0.30% in May.

As long as inflation is over goal, traders predicted that the majority of forecasts that the Fed will lower rates this year.

Investors are particularly interested in whether demand issues would arise if the U.S. Treasury dramatically increases the issuance of Treasury bills to replenish its cash balance after raising the debt ceiling.

The dollar index that gauges the greenback versus its major pairs dipped 0.29% at 103.77.

EUR/USD added 0.03% at $1.0726.

USD/JPY slipped 0.22% to 139.33 yen.
