In a prospectus published ahead of a huge bond sale, Saudi Aramco revealed for the first time how much money it makes. Saudi Arabia's state oil firm reaped $356 billion in revenue last year. Annual net profit came to $111 billion, almost twice that of Apple, the world's most valuable listed company. The prospectus also confirmed how important Saudi Aramco is to the country's economy. Oil accounted for 63 percent of the state's revenue in 2017 and 43 percent of the kingdom's GDP.

India's Supreme Court ruled that the Reserve Bank of India had overstepped its mark when directing banks to declare a default when a company defers loan payments and force the company into bankruptcy if it does not resolve its debt position within 180 days. The court found that the central bank could intervene on individual corporate defaults but could not undertake such a sweeping action. It is a big blow to the RBI's effort to rein in India's corporate debt.
