Fg loses 518m opa oil swap deals

It seems like you're referring to a news article about a significant financial loss. Here's a breakdown of the information:

From what I can gather, the Federal Government of Nigeria has lost a significant amount of money (approximately 518 million Naira) due to the failure of oil swap deals. Oil swap deals are a type of financial arrangement where the government agrees to receive a certain amount of oil or petroleum products in exchange for a specific amount of cash or other financial instruments.

It's likely that the government has entered into these deals with oil companies or other entities, and for some reason, the deals have not been fulfilled or have been terminated, resulting in a significant financial loss.

If you'd like to know more about the specific circumstances surrounding this loss, I'd be happy to help you find more information or provide context.
