Hong Kong's survival as a global financial hub can no longer be taken for granted. The extradition battle being fought out on the streets of Wan Chai is inextricably tied to the larger Sino-US struggle for superpower hegemony.
The more that Beijing chips away at Hong Kong's civil liberties and autonomy, the more certain it is that Washington will strip the enclave of its special status.
Once this line is crossed, the US will cease to recognise the territory as an independent member of the World Trade Organisation. It will cut off access to sensitive technologies. Hong Kong will be subject to the same painful tariffs faced by exporters from mainland China.
Many of the 1400 US firms operating there will decamp, setting off an exodus towards Singapore. The Hong Kong model as we know it will no longer be viable.
The US has been slow to act as China erodes the "one nation, two systems" model established by Britain and China in 1984. The mood has changed.
The Hong Kong Human Rights and Democracy Act introduced in the US House and Senate last week — backed by both parties — cocks the trigger on what amounts to a sanctions regime covering trade, finance, and technology.
"If all this rolls out, Hong Kong is going to be just another Chinese city," said one of the drafters.
The text links directly to the Emergency Economic Powers Act and calls for punitive action if Beijing further eviscerates the enclave's legal autonomy.
For the status quo to continue, the US Administration must justify to Capitol Hill why the territory still deserves special treatment under the US Hong Kong Policy Act of 1992.
The rating agencies have begun to issue warnings. Fitch says its AA+ grade "rests on the assumption that the territory's governance standards, rule of law, policy framework, and business and regulatory environments remain distinct from that of mainland China".
Carrie Lam, Hong Kong's Chief Executive, suspended the extradition bill but remains defiant. She called the legislation a necessary objective — a "good thing" — and left no doubt that the authorities are playing for time.
Swarms of demonstrators again poured out into the streets yesterday. Their goal has changed. They now demand Lam's resignation. The protests carry an echo of Tiananmen Square about them.
While the news focus has been on the danger of extradition to China for such offences as "picking quarrels" or "running an illegal business" — standard charges used to suppress dissent in China — Hong Kong's business elites are just as alarmed by other clauses.
The bill calls for "freezing and confiscating the assets of persons wanted for crimes in other jurisdictions". It brings the vast wealth of Hong Kong within reach of the Communist Party for the first time.
It is not easy to destabilise a well-established hub. But political shocks can bring matters to a head. Antwerp was Europe's commercial hub and the world's richest city in 1560, a freethinking outpost of the Spanish Habsburg empire. The fall was swift once the Habsburgs began to choke its liberties and the counter-reformation reached fever pitch. Credit Suisse says there are over 850 individuals in Hong Kong who are each worth more than US$100 million. Reuters reported that one tycoon with political "exposure" in China is already shifting sums of this magnitude to accounts in Singapore.
Hong Kong is the financial gateway in and out of China, a conduit for Chinese companies with US$840bn of US dollar debt. Its banking system is 8.3 times GDP, comparable to Iceland before its system blew up in 2007. A sudden loss of confidence in Hong Kong would have global systemic consequences.
The bill in Congress tees up sanctions against those "complicit in suppressing basic freedoms in Hong Kong". It effectively stamps the scarlet letter on the enclave's top leadership. The bill demands a clampdown on sales of dual use technology and action to verify whether China is using Hong Kong as a back door to circumvent US tariffs.
Ultimately it is the prerogative of US President Donald Trump to decide whether to suspend special status. He has been coy on the issue, stating distractedly last week that "I hope it all works out for China and for Hong Kong". Trump is unlikely to stand in the way of Congress for long. Hong Kong's protests offer him another irresistible weapon against Beijing.
