The sharp rise was due to more Vietnamese working overseas after many countries eased immigration policies to source workers post-Covid, according to the State Bank of Vietnam's HCMC branch.
Remittances are likely to rise by 20% next year as global economies recover, it said.
City deputy chairman Vo Van Hoan said there has been great focus on trade promotion, attracting investment and conversing with the foreign business community this year.
The rise in remittances would help the city grow as a financial center, he added.
Remittances to HCMC had reached $6.6 billion by the end of September, up 40% year-on-year and including more than $2.35 billion received in the third quarter.
HCMC has often accounted for half of all remittances coming to the country.
