The ratio of bids to the amount of 10-year TIPS offered was 2.39, up from 2.27 at the prior auction in May and the highest since March 2015.
Indirect bidders which include fund managers and foreign central banks purchased 68.38 percent of the latest 10-year TIPS issue, which was their biggest share since September 2015.
Small dealers and other direct bidders bought 7.71 percent of the 10-year TIPS supply, which was their largest since January.
Primary dealers, or the top 23 Wall Street firms that do business directly with the Federal Reserve, purchased 23.91 percent, which analysts said was their second smallest share on record.
On a breakeven basis, which gauges investors' view on longer-term US inflation, the yield difference between new 10-year TIPS and regular 10-year Treasuries was 1.53 percent versus 1.52 percent shortly before the auction, Tradeweb data showed.
Strong bids at Thursday's auction trimmed the 10-year TIPS yield's rise on the open market.
It was last 0.098 percent, compared with 0.109 percent prior to the auction, according to Tradeweb.
