Ray Dalio warns that Moody's credit downgrade doesn't reflect the risks of money printing by the federal government in order to pay off debt.

HONG KONG (AP) — Global shares fell Monday and U.S. futures and the dollar also weakened after Moody’s Ratings downgraded the sovereign credit rating for the United States because of its failure to stem a rising tide of debt.

The decision could impact financial markets, raise interest rates, and highlight fiscal challenges for the U.S. government.

Investors will get the first chance to react to Moody’s downgrade of the U.S. credit rating late Friday over rising government debt and they’ll also look for more progress from President Trump on trade deals as the week kicks off.

Moody's downgrade of the U.S. sovereign credit rating has elicited mixed responses among Republicans in Congress, with some questioning the motive behind the change and others depicting it as a warning that lawmakers should heed as they wrestle with a sweeping tax and budget bill.
