Major indexes fell across the board on the U.S. financial markets in New York on Jan. 30 (local time), sharply dampening investor sentiment. The Dow Jones Industrial Average fell about 0.28 percent to around 48,932. The S&P 500 and the tech-heavy Nasdaq also fell about 0.29 percent and 0.35 percent, respectively.

According to overseas media including the Economic Times, the pullback came as uncertainty in financial markets widened after U.S. President Donald Trump announced he had nominated former Fed governor Kevin Warsh to succeed Federal Reserve Chair Jerome Powell. The news stirred caution among investors factoring in the possibility of rate hikes as interpretations differed over the future direction of monetary policy.

As a result, the 10-year Treasury yield rose and the dollar strengthened, weighing on appetite for risky assets. The stronger dollar put downward pressure on gold and silver, sending the precious metals sharply lower. Gold fell more than about 4 percent, and silver posted an almost double-digit decline. International silver futures plunged about 31 percent in a day, underscoring extreme volatility.

Market experts said debate over the Fed chair nomination and a reset of rate expectations increased market volatility. They said a temporary adjustment is emerging as investors shift from safe-haven assets back to risk assets. Even so, the indexes were assessed as still maintaining a strong trend as of late January when viewed on a monthly basis.

Markets also reflected some risk from the Trump administration's trade policy. After Trump mentioned the possibility of imposing high tariffs on Canadian aircraft and other goods, concerns over global supply chains resurfaced. Some interpretations said that helped intensify selling, led by industrial shares.

Overall, U.S. stocks were seen as investors quickly cutting exposure as changes in the macro environment overlapped with monetary and trade risks. The direction of interest rates and the Fed's policy stance were assessed as remaining key variables for the market.
