The rupee was linked to the British pound from 1927 to 1946, and then to the US dollar until 1975 through a fixed exchange rate. It was devalued in September 1975 and the system of fixed par rate was replaced with a basket of four major international currencies: the British pound, the US dollar, the Japanese yen and the Deutsche mark.[324] In 1991, after the collapse of its largest trading partner, the Soviet Union, India faced the major foreign exchange crisis and the rupee was devalued by around 19% in two stages on 1 and 2 July. In 1992, a Liberalized Exchange Rate Mechanism (LERMS) was introduced. Under LERMS, exporters had to surrender 40 percent of their foreign exchange earnings to the RBI at the RBI-determined exchange rate; the remaining 60% could be converted at the market-determined exchange rate. In 1994, the rupee was convertible on the current account, with some capital controls.[325]
Since independence, India's balance of payments on its current account has been negative. Since economic liberalisation in the 1990s, precipitated by a balance-of-payment crisis, India's exports rose consistently, covering 80.3% of its imports in 2002–03, up from 66.2% in 1990–91.[287] However, the global economic slump followed by a general deceleration in world trade saw the exports as a percentage of imports drop to 61.4% in 2008–09.[288] India's growing oil import bill is seen as the main driver behind the large current account deficit,[289] which rose to $118.7 billion, or 11.11% of GDP, in 2008–09.[290] Between January and October 2010, India imported $82.1 billion worth of crude oil.[289] The Indian economy has run a trade deficit every year from 2002 to 2012, with a merchandise trade deficit of US$189 billion in 2011–12.[291] Its trade with China has the largest deficit, about $31 billion in 2013.[292]

India started recovery in 2013–14 when the GDP growth rate accelerated to 6.4% from the previous year's 5.5%. The acceleration continued through 2014–15 and 2015–16 with growth rates of 7.5% and 8.0% respectively. For the first time since 1990, India grew faster than China which registered 6.9% growth in 2015.[needs update] However the growth rate subsequently decelerated, to 7.1% and 6.6% in 2016–17 and 2017–18 respectively,[144] partly because of the disruptive effects of 2016 Indian banknote demonetisation and the Goods and Services Tax (India).[145] As of October 2018, India is the world's fastest growing economy, and is expected to maintain that status for at least three more years.[146]
In March 1953, the Indian Parliament passed the Air Corporations Act to streamline and nationalise the then existing privately owned eight domestic airlines into Indian Airlines for domestic services and the Tata group-owned Air India for international services.[197] The International Airports Authority of India (IAAI) was constituted in 1972 while the National Airports Authority was constituted in 1986. The Bureau of Civil Aviation Security was established in 1987 following the crash of Air India Flight 182.
The government de-regularised the civil aviation sector in 1991 when the government allowed private airlines to operate charter and non-scheduled services under the 'Air Taxi' Scheme until 1994, when the Air Corporation Act was repealed and private airlines could now operate scheduled services. Private airlines including Jet Airways, Air Sahara, Modiluft, Damania Airways and NEPC Airlines commenced domestic operations during this period.[197]
