(Reuters) -The dollar gained on Tuesday, giving back earlier losses, as benchmark U.S. Treasury yields hit a four-week high following some weak auctions.

The Treasury Department saw soft demand for sales of two-year and five-year notes. They came after data showed that U.S. consumer confidence unexpectedly improved in May after deteriorating for three straight months.

“The bond market has turned around today and the dollar with it,” said Adam Button, chief currency analyst at ForexLive in Toronto, citing the weak auctions and noting that the improving consumer confidence report reflects “stronger growth.”

U.S. economic data was better than expected in the first quarter and so far there are no major signs of deterioration in areas such as the labor market, which some traders are waiting on before taking a more bearish view on the greenback.

Concerns that inflation will remain stubbornly above the Fed’s target for longer are also providing some support for the U.S. currency. Tuesday’s data showed that worries about inflation persisted and many households expected higher interest rates over the next year.

Minneapolis Federal Reserve Bank President Neel Kashkari said on Tuesday that the U.S. central bank should wait for significant progress on inflation before cutting interest rates and added that the central bank could potentially even hike rates if inflation fails to come down further.

Consumer price inflation showing that prices increased less than expected in April briefly boosted hopes that the Fed is closer to cutting rates, but Fed officials have stressed that they want to see several more months of progress before easing policy.

“The Fed is in no rush to cut rates,” said Button. He added, “the American economy is uniquely strong. It's tough to bet against the U.S. dollar until the weakness is confirmed.”

This week’s main U.S. economic focus will be personal consumption expenditures due on Friday, which is the Fed’s preferred inflation measure.

The dollar index was last up 0.03% at 104.59, after earlier dropping to 104.33. The euro gained 0.01% to $1.0859. Sterling weakened 0.05% to $1.276.

The European Central Bank's Francois Villeroy de Galhau on Monday confirmed market expectations that, barring major surprises, a first rate cut next week is a done deal. But investors have recently updated their bets on future ECB moves, pricing in less than a cut in every quarter in 2024 and early 2025.

German inflation data due on Wednesday and the wider euro zone's reading on Friday will be watched for clues on how soon easing from the central bank could come.
