With the exception of one small company listed on the second-tier market, none of the 32 listed companies on the firsttier of the stock exchange are in the energy sector. In addition, of the $ billion of (private) securities floated on the domestic capital market in the last decade, none were for local energy sector companies.
And here I am defining the energy sector in the broad sense, comprising: (i)  upstream – largely multi-national firms specializing in exploration and the production (mining) of oil and gas;  (ii)  the downstream petro-chemical sector (also largely foreign owned); and  (iii)  the energy services sector (the smaller firms that provide support services) – these are largely locally-owned, though there are three multi-nationals that also operate in this sector.
