London-listed Standard Chartered is close to completing talks to resolve US investigations into its Iran-linked transactions and nearing agreement on a fine in the region of $300 million, Reuters has reported, citing four unnamed sources.

The bank, as previously reported by this publication, agreed in August to pay New York's banking regulator $340 million after the authority filed an order accusing Standard Chartered of hiding some $250 billion worth of transactions with Iran.

In its interim results statement earlier this week, the bank said: "The group continues to engage with the other US agencies on their review of the group’s historical US sanctions compliance." 

Standard Chartered has been in talks recently to resolve remaining probes against it from other US institutions, through a joint settlement, the news service quoted the sources as saying.

In an update on its quarterly performance, Standard Chartered’s finance director said earlier this week it was aiming for a final settlement by the end of the year.

Reuters said representatives of the bank and the US authorities concerned either declined to comment or did not immediately respond to a request for comment.

Standard Chartered earns the bulk of its revenues outside the UK, with a particular focus on regions such as Asia.
