Oil prices just crashed 20% — and it's shaking the world's safest investment

U.S. government bonds are hovering near two-month lows after oil prices fell 20% in a week. The drop comes as midterm election results point to a divided government. Treasury yields, which move opposite to bond prices, rose as investors moved money out of safe assets. A "midterm sweep" — one party winning control of both chambers of Congress — added to the shift. Oil's sharp fall and the election outcome together are pushing investors to rethink where they put their money.
