Forex inflow from the Central Bank of Nigeria's (CBN's) bi-weekly auction declined by 17.3 per cent to $10.02 billion in the second quarter, from N11.730 billion the preceding quarter.
The apex bank disclosed this in its second quarter report posted on its website Wednesday.
This however represented an increase by 13.2 per cent above the level in the corresponding quarter of 2011.
According to the CBN, outflow during the period under review, amounted to $9.61 billion, showing a decline of 1.5 and 12.4 per cent below the levels in the preceding quarter and the corresponding quarter of 2011, respectively.
"This resulted in a net inflow of $0.41 billion, compared with a net inflow of $2.36 in the preceding quarter. However, it contrasts with a net outflow of $2.12 billion recorded in the corresponding quarter of 2011.
"The fall in inflow relative to the preceding quarter was attributed to the decline in crude oil sales and non-oil receipts, while the fall in outflow was attributed to the decline in the WDAS Forward Contract and NNPC/JVC Cash Calls payments," it added.
Available data on aggregate forex flows through the economy indicated that total inflow amounted to $27.43 billion, representing a decline of 3.0 per cent below the preceding quarter. But it reflected an increase of 19.5 per cent above the level in the corresponding quarter of 2011.
