An auction of $5 billion of 30-year Treasury-inflation protected securities, or TIPs, Thursday saw a record share taken down by indirect bidders, a proxy for foreign investors. Around 81% of the supply was bought up by indirect bidders, versus a 12-month average of 72%. The auction also “stopped” at 1.1 basis points at 0.934%, a sign the bond sale drew strong demand. The TIP exchange-traded fund is up by 0.7% for the month. Economists say inflation may be set to rise in the next few months amid building pipeline costs and a labor market at its tightest in several decades. Consumer price inflation ran at an annual pace of 2.8% in May, its fastest pace in six years.
