As economic trends indicate the 10-year and other U.S. Treasurys could tank even lower, Pimco has shied away from U.S. bonds.
"It's going to be very difficult to get 4 or 5 percent in the bond market unless you buy bank loans or unless you buy emerging market bonds," Kiesel said.

He also discussed the Pimco Total Return Fund, which suffered through a dismal 2014 marked by record outflows. The fund has started to recover since September and has outperformed most of its competition since, Kiesel said.
The fund currently favors international markets, like Brazil and Mexico, and Treasury Inflation-Protected Securities, which the firm believes are "very cheap."
