The reserves reached the milestone on Monday, said Bangladesh Bank’s spokesman Serajul Islam said.
It means the country can pay import costs of more than 11 months with the reserves.
The foreign exchange reserves jumped by nearly $12 billion in a year as the Bangladeshi migrants continued sending money amid the coronavirus pandemic.
Ahead of Eid-ul-Fitr, they sent a little more than $2 billion in April, a 89 percent year-on-year rise.
In the first 10 months of the fiscal year, from July to April, the expatriates sent $20.67 billion.
Export earnings also fed the reserves. Bangladesh exported goods worth $32.7 billion in the July-April period with a 8.74 percent year-on-year growth.
