Warren Buffett dismisses Fitch's US credit rating downgrade

Warren Buffett remains unfazed by Fitch's downgrade of America's credit rating, stating that there are some things people shouldn't worry about. Berkshire Hathaway continues to buy $10 billion of US Treasuries every Monday, emphasizing his confidence in Treasuries and the US dollar as the world's reserve currency. Buffett's optimism is rooted in the increased value of Berkshire's Treasuries due to the Federal Reserve's interest rate hikes. Fitch's rating cut, which cited rising debt levels and weakening governance, has spooked investors, but Buffett remains confident in America's prospects.
