The government is to sell off another 5% of its stake in AIB.
The state has been selling off shares slowly since bailing out the bank in 2010.
At one point, 98% of the bank was owned by the government, and the latest sale of shares will bring their holdings down to 57%.
Business journalist Joe Lynam says the state's investment in the bank has proven to be a good one.
"Just remember that the Irish taxpayer has pumped in €3.7bn to rescue the bank.
"The bank in market terms is worth €8.3bn at the moment and the Irish state would have enjoyed dividends in the meantime.
"So far that has proved to be a good investment 2010, though it was pretty expensive at the time because the state was broke."
