I’m not sure what is available in France…but here is a list of all the sukuk available to a UK investors (plus other things like stocks and commodities and gold).
In the UK we also have Islamic Banks…and we can get 2.35% fixed income from those so I have parked some money in that.
Regarding sukuk…it is down this year also…e.g. SPSK is -12% YTD. All asset classes are down this year.
