To see detail of the BD economy, check the following wiki link (not 100% accurate though):
Economy of Bangladesh - Wikipedia, the free encyclopedia
GDP (nominal) for BD is now: $173bn
Per capita GDP is now: $1180
Exports are approx: $35bn
Imports are approx: $33bn
Remittance is around: $15bn
The consensus amongst most economists are that, exports are going to expand at a much faster rate then imports, the number of workers going abroad will increase only marginally though the remittance will continue to grow. The foreign exchange reserve more then doubled in the last 5 years, and will more then double in the next 5-6 years as the BB continues to buy dollar to keep the taka "affordable" for exporters.
The government most likely will look to improve the ratting to A from BB-, reducing the cost of borrowing further. My predictions for the next 5-6 years (2020) are as follows:
Average GDP growth: 6.5%-7%
Exports: $55bn plus
Imports: $47bn plus
Remittance: $19bn
Reserves: $43bn
