The trade gap is an arbitrary man-made definition that refers to only merchandise goods trade in the balance of payments.
Sri Lanka has a large trade deficit because the spending power in the country is boosted by exports of items other than merchandize trade goods.
These include exports of labour (1,492 million US dollar in the first quarter), exports of government debt (government borrowing of 1.162 million US dollars) and exports of services to tourist (268.3 million US dollars).
Sri Lanka's rupee fell steeply in March mainly from the pent up pressure of rupees injected to the banking system to sterilize forex sales which fires unsustainable credit and demand.
The rupee has continued to come under pressure in subsequent months partly due to sterilized sales of foreign exchange for oil payments and also from unsterilized foreign exchange purchases, which built up rupee liquidity and fired credit.
