Stocks plummeted Thursday as the federal government edged closer to a partial shutdown and traders braced for the impact of further Federal Reserve rate hikes.

The Dow Jones Industrial Average lost 464 points, or 2 percent, falling to a 14-month low, while the S&P 500 and Nasdaq Composite slid 1.8 percent and 1.6 percent, respectively.

The Nasdaq’s losses briefly sunk the composite into a bear market — a 20-percent drop from its latest high-point.

The losses amplified a Wednesday decline triggered by the Fed hiking interest rates and projecting two further rate hikes in 2019. ADVERTISEMENT

Traders had hoped the Fed would hint toward a pause in hikes, which suppress the stock market by driving up borrowing costs and squeezing corporate profit margins.

Thursday’s sell-off brought stocks to new lows for 2018. Without a rebound, stocks are on track for their worst December in decades. It would also represent the first time since the Great Depression that markets closed the year lower than they started.
