On June 12, Gundlak, the "new debt king", said on Wednesday that the U.S. debt burden and interest expenses have become "unsustainable," which means that long-term U.S. debt is no longer regarded as a truly risk-free investment. He compared the current market environment to the situation before the bursting of the Internet bubble in 1999 and before the global financial crisis of 2006 - 2007. He said investors should consider increasing the allocation of non-US dollar assets and revealed that the company he manages is starting to include foreign currencies in its funds.
