## Root Cause

Since the People's Bank of China (PBOC) tightened cross-border card rules in 2022, foreign-issued UnionPay cards have a hard daily transaction limit of ¥10,000 (approx. $1,400) for in-store purchases, with a separate ¥5,000 ATM withdrawal limit per day, enforced by the China UnionPay clearing system

## Workarounds

## Dead Ends

- **** — The limit is enforced by China UnionPay's domestic clearing system, not the issuing bank; the bank cannot override PBOC regulations (100% fail)
- **** — The cap is cumulative across all merchants in a rolling 24-hour window; once the total exceeds ¥10,000, all subsequent transactions are declined (95% fail)
- **** — Foreign-issued UnionPay cards registered in Chinese wallets are subject to the same ¥10,000 daily cap, plus an additional ¥5,000 wallet transfer limit (90% fail)
