Bill Gross is warning about the end of the bull market in bonds and a coming era of inflation, in his latest Investment Outlook.

As investors, including China, question negative returns (inflation adjusted) they will shift into “real assets such as land, gold and tangible things, or to cash and a figurative mattress where at least their money is readily accessible.”

He sees a coming “breaking point” that looks towards “higher global inflation as a solution to overextended debt-laden balance sheets – be they public or private.”
