LGPS pool Wales Pension Partnership (WPP) is to launch two more sub-funds during 2019/20, bringing its total to four.
An update report to Cardiff Council this week said that the two new sub-funds would cover regional equities and fixed income.
WPP launched its first two sub-funds covering global growth and global opportunities and worth £4bn, in January.
The report also said that the pool is developing a responsible investment policy, a draft of which will be presented for review in September.
