Tighter olefin market and lower naphtha feedstock cost – The olefin market
was entering a down cycle in 2008-09 and the market recovered only in 2013.
We expect an improving demand-supply balance in the olefin market in 2015-
16E, by comparison with the large excess supply in 2010-12. The fall in
naphtha feedstock costs, led by low oil prices and oversupply in the naphtha
market, should also keep chemical margins at high levels, in our view.
