Managed by Scott Smith and Jonathan Terry, the fund will invest in dollar-denominated debt securities that are rated investment grade at the time of purchase.
The new product is a sub-fund of the Wells Fargo Worldwide Luxembourg Ucits fund that was launched in December and has so far raised over $100m (£80.6m).
The managers will use bottom-up investment research to build a focused portfolio of well-underwritten credit securities.
Available to retail and institutional investors, the fund is available in Luxembourg, Austria, Finland, France, Germany, Ireland, Italy, the Netherlands, Norway, Spain, Sweden, Switzerland, Singapore and the UK.
It will be registered in Hong Kong and South Korea in the next phase.
