1) "Dollar shortage acute in China".
I admit IDK. 🇨🇳entities obtain and use dollars outside of 🇨🇳.
2) "HSBC caught lending some $400-700B [to 🇨🇳]"
I have seen exactly ZERO data to back this up.
3) SO Banks buying $ in ONshore fwds.
Huh? Really?
The HSBC rumor. Puhleeez show your data. ANY data.
Are you suggesting HSBC fired their CEO because of this and THEN...
Next, doing buy-sell swaps then supporting the yuan on a forward basis sucks USD from some corners of China into other corners. It does not change the "China $ shortage."
