Citigroup is attempting its biggest acquisition since the US Federal Reserve ordered a hiatus on "significant" purchases last year after reaching the final round of an auction for Turkey's Finansbank, which could fetch up to $5bn (€4.1bn).

The Wall Street Journal reports that the bank is set to go head-to-head with the National Bank of Greece, which has also made it to the final round of bidding in an auction run by Morgan Stanley.
