The latest Fortune Global 500 marks the silver jubilee of Indian Oil Corporation (IOC) on the coveted list of the world’s largest corporations. Till last year, it had been the top ranked Indian company on it and No. 1 on the Fortune India 500 list since the list’s inception in 2010.

This year, ranked 106, Reliance Industries (RIL) has replaced IOC (117) as the top-ranked Indian company on the Global 500 list. RIL’s revenue soared 32.1% from $62.3 billion in 2018 to $82.3 billion in 2019, while IOC clocked a 17.7% growth in revenue from $65.9 billion to $77.6 billion. Over the past 10 years, RIL’s revenue rose at a compounded annual growth rate of 7.2% from $41.1 billion in 2010, while that of IOC rose at 3.64% from $54.3 billion in 2010.

The journey of RIL, which marks its 16th year on the Global 500 list this year, to the top position has been interesting. The average difference of its revenues with that of IOC was $9.4 billion in the nine years from 2010 to 2018. The difference was as high as $13.2 billion in 2010. The gap started to narrow after 2016 when RIL’s revenue was $11.3 billion lesser than IOC. The difference further fell to $6.6 billion and $3.6 billion in 2017 and 2018, respectively, and RIL surpassed IOC by $4.7 billion in 2019.

Interestingly, 2012 also saw RIL’s second highest revenue of $76.1 billion; the absolute increase in RIL’s revenue between 2012 and 2019 is $8.2 billion. At the 2012 peak, IOC and RIL were ranked 83 and 99, respectively, on the Global 500 list. In 2018, RIL was ranked 148 and IOC, 137.
