Is this the most you refer to? https://www.six-group.com/dam/download/financial-information/data-center/iso-currrency/lists/list_one.xml
Just went down this rabbit hole for a few minutes. The idea of different currency codes is super interesting. It's well known that the Swiss Frank has a complimentary current: the vemeer. Both notes are legal tender so there's clearly a precedent for this system existing. If the currency is not technically a liability, then they could still issue another currency booked as a liability backed by assets/reserves.
Okay I found this: https://www.channelnewsasia.com/business/shanghai-lockdown-does-not-impact-taiwan-firms-production-taiwan-minister-2590276
I now think this may have more to do with putting pressure on Taiwan than it does putting pressure on Apple or US.
The timing (early January, early March) also seems to coincide with AAPL earnings.
