HK, mainland stocks post gains

On Wednesday, stock markets experienced an overall increase as investors evaluated the effects of the Democratic Party's victory in the US Congress. This outcome posed a challenge to Donald Trump's economic policies as he enters his final two years in office. In Hong Kong, the Hang Seng Index climbed for the fourth consecutive day, surging 1.67 percent to 23,919.

Similarly, mainland shares also gained, with the Shanghai Composite Index increasing 2.16 percent to 3,686 and the Shenzhen Component Index rising 4.22 percent to 11,335. In contrast, the Nikkei in Japan saw a decline of 1.42 percent to 62,188, primarily due to losses in technology stocks. The South Korean Kospi index, on the other hand, ended 0.62 percent higher at 5,683.

The possibility of Congress becoming gridlocked had a negative impact on the US dollar and Treasury yields, as experts noted that such a scenario would limit government spending. With Democratic control of Congress, it would be more difficult for the White House administration to enact significant partisan legislation. This situation might limit the likelihood of substantial additional fiscal stimulus in the coming years, according to David Chao of Invesco.

For Asia, these dynamics are significant. Reduced fiscal stimulus could lower upward pressure on US growth, inflation, and Treasury yields, which might alleviate some of the pressure from elevated US interest rates and a stronger dollar on Asian currencies and monetary policy.
