Tensions between U.S. and China took center stage this week. China announced on Friday that it ordered the United States to shut its consulate in Chengdu, following the U.S. demanding the closure of the Chinese consulate in Houston.
Preceding that, Secretary of State Mike Pompeo also slammed China in a speech on Thursday. He said Washington will no longer tolerate Beijing's attempts to usurp global order.
"For now, US-China conflict risks are poised to reinforce pre-existing negative bias in the Asia session, derived from 1.2%-1.3% drop in Wall St that had predated Pompeo's remarks," Mizuho Bank's Vishnu Varathan, head of economics and strategy, wrote in a note.
He said regarding China's response to the escalating tensions, that it's likely to try to keep currency and stock markets stable.
"We expect the PBoC (People's Bank of China) to double down on CNY (Chinese yuan) stability," Varathan wrote. "What's more, this will be complemented by policies that support 'reasonable' buoyancy in equity markets, which help boost wider wealth creation, increase access to capital for industry champions (to better position against US), and crucially underpin capital stability."
