Macquarie Credit Union is in merger discussions with Regional Australia Bank. The combined entity would have assets of A$3.4 billion. Two years ago, Macquarie opened merger negotiations with Orange Credit Union (also based in the central west of NSW), which came to nought. There have been few mergers between mutual ADIs in recent years, and the interest of Macquarie (the seventh-smallest mutual) in pursuing a merger with RAB (the 12th largest) may be a beginning in the turn of the tide.
