You're exaggerating what this tiny incident means to the market. Historically this doesn't show up on the list at all, it's just barely a one day top 10 business story.
The market in this context effectively means the top 30 or 40 economies. They make up the extreme majority of all global GDP.
What practical alternative to the US as an essential ally in the coming global bifurcation with China and Russia do you perceive that: EU, Japan, South Korea, Australia, New Zealand, Canada, Mexico, UK, etc - have? Who else is there? There is nobody else to help offset the enormity of China's looming power. The US has, on many occasions since WW2, done radically worse than arrest a Huawei executive over sanctions on a foreign nation. Mr. Market barely blinked over Snowden and the global espionage revelations for example, which was a thousand times worse than this incident. It had enormous commerce implications. For the most part the world went on with its business; and here we are years later, the US espionage system continues unabated (actually it's stronger now) and mostly unchallenged. This arrest will barely matter at all to Mr. Market.
You have very restricted definition of market. Market != Stock Market. Slap of market does not mean you go down, it means the profits goes to your compititors. Rise of China is textbook example here. China made the bank, while everyone who did not have compititive labor regulations got slapped for it. Globalisation basically means States getting slapped for not being competitive.
There are whole categories of companies/products (OVH/ProtonMail/etc) due to NSA. So yes USA got slapped for it too just not as visible as Rise-of-China.
