Recently, Fitch's downgrade of the U.S. credit rating has made waves in the capital markets。U.S. bond yields are starting to rise and U.S. stock indexes are falling, which seems to signal that disaster is coming。In these circumstances, some investors are ready to leave the market, but others believe that there is no need to worry too much about this downgrade.。Obviously, Buffett belongs to the latter.。Recently, Buffett told the media that he was not concerned about Fitch's downgrade of the U.S. and that the incident would not affect his investment strategy。In his words, the question he is considering is not whether to buy U.S. Treasuries or not, but what maturity to buy U.S. Treasuries。Of course, the stock god this speech, not standing to speak not waist pain, in order to support the U.S. Treasury bonds, he also paid real money.。According to him, his Berkshire company has recently bought $10 billion in U.S. Treasuries and is completely unafraid of Fitch's downgrade of the U.S. credit rating。Buffett always seems to have confidence in the U.S. financial system.。In April, just as the banking crisis was simmering, the investment legend had said that while the banking turmoil was not over, there should be no panic about the safety of the banking sector or deposits, as the U.S. government could step in to support depositors in all U.S. banks if necessary。At the height of the banking crisis, Buffett's statement was questioned by some in the media, and he came out again to claim that no one would lose money on a deposit in a U.S. bank, which simply could not have happened。To that end, he's even willing to make a bet with the market at $1 million.。Later, it turned out that the U.S. banking crisis did not erupt into a systemic crisis and losses were minimized。
