DHAKA, Sept 4 (Reuters) - Bangladesh's foreign exchange reserves hit a record high of $33.60 billion at the end of August, the central bank said on Monday, up $690 million from the previous month.

The reserves are sufficient to cover about 10 months' worth of imports for the country of 160 million people, and are $3.55 billion higher than a year ago.

Steady garment exports and remittances from Bangladeshis working overseas, the key drivers of the country's more than $200 billion economy, have helped foreign exchange reserves grow steadily in recent years. (Reporting by Ruma Paul; Editing by Subhranshu Sahu)
