During its first five years of independence, Bangladesh adopted socialist policies. The subsequent military regime and BNP and Jatiya Party governments restored free markets and promoted the country's private sector. In 1991, finance minister Saifur Rahman introduced a programme of economic liberalisation. The Bangladeshi private sector has rapidly expanded, with a number of conglomerates driving the economy. Major industries include textiles, pharmaceuticals, shipbuilding, steel, electronics, energy, construction materials, chemicals, ceramics, food processing, and leather goods. Export-oriented industrialisation has increased with fiscal year 2018–19 exports increasing by 10.1% over the previous year to $40 billion. Most export earnings are from the garment-manufacturing industry.
