U.S. Treasurys yields rose to their highest in three weeks on Tuesday as investors reset bets that yields are likely to climb after they fell to 11-month lows last week and as German government debt weakened.
Yields have risen this week after month-end buying from last week dissipated.
U.S. bond yields rose with German bund yields on Tuesday after euro zone inflation data was in line with revised expectations, prompting some in the market who had expected an even weaker number to book profits after a recent rally.
Investors have also covered bets that yields would rise in recent weeks, which helped to push them lower. But traders said those bets were being reset, which is put pressure on the bonds and sent yields higher again.
"I think the short base is building again,'' said Tom Tucci, head of Treasurys trading at CIBC in New York. The difference between the number of investors who said they are bearish on U.S. long-dated Treasurys exceeded those who are bullish grew to its biggest in eight years, according to a J.P. Morgan survey released on Tuesday.
