In Pakistan, three major ways the country earns foreign exchange are:

1. Exports: International trade helps Pakistan earn the foreign currency which is proceeded by the exports of both goods and services. This includes the production of textile, leather and also clothing which are also included in this list as well as the production of rice, fruits and vegetables. Exporting goods helps Pakistan in generating foreign currency earnings that it can receive in return for those products which it sells overseas. A country does so by capitalizing on its natural resources and available workforce and getting them to manufacture goods that are in demand worldwide.

1. Remittances: Pakistan earns a great sum of foreign exchange through the remittances sent by Pakistan natives working abroad. Majority of the immigrants are the Middle East, Europe and North America. Such remittances are sent home to assist the families in payments of rent or provision of necessities and are used for country's economic benefit. Remittances serve as a steady provider of foreign currency revenues and significantly boost lifestyle of large Pakistanis.

2. Foreign Direct Investment (FDI): Foreign direct investments hold the prospects of bringing foreign investors in ventures and obtaining shares in the local enterprises in Pakistan. FDI imparts a boost to the GDP, labour creation of jobs and spillovers of technology. It attracts foreign resources, which encompass capital flows, knowledge, and technology used to improve efficiency and competitiveness in several areas like the telecommunications, energy and manufacturing industries. Inward investments or FDI flows increase the country’s foreign exchange reserves and help promote the economic status.

In Pakistan, the textile industry, as a matter of fact, takes the foremost place in foreign trade. Our country has the biggest textile market in the world and is the substantial contributor to the national income of our country. There are several reasons why the textile sector is the leading contributor to foreign exchange earnings:

1. Export-oriented nature: The textile sector of Pakistan mainly focuses on exports and the amount of goods sold in the international market constitute a great share of Pakistan’s exports. Pakistan is particularly famous for generating an extensive range of textile articles including cotton yarn, fabric, dresses and home textiles that are exporters worldwide.

2. Employment generation: The textile sector in Pakistan is one of the biggest employers, as it has a large share of labor force:. millions of people, who mostly work in the rural regions, where their chances of becoming employed in the other kinds of work are extremely limited. The wider section of a society that is covered by manufacturing deepens the understanding of the contribution of this industry to the country's economy.

3. Value addition: Cotton production in Pakistan is interwoven through various stages of production like spinning and weaving, hank-twisting, etc. It enhances the competitiveness of Pakistani textile commodities in the foreign markets by providing the industry with higher earning. It further helps the country generate a good share of foreign exchange revenue.

4. Government support: Pakistan's government has rendered substantial support and encouragement to the textile industry for years, the forms of which are subsidies, tax reductions and export incentives, and by doing so, the country's capability of exporting commodities is to be enhanced and the foreign exchange reserves are to increase. These policies served as boosting pillars of the textile industry helping it to ensure stable profits in global markets.

Hence, this sector receives top ranking amidst export outlook, employment generation, value addition, and government support which consequently allows Pakistan to have large foreign exchange revenues.

Although textiles is among the sectors which is engaged in generating foreign exchange for Pakistan forever, the accumulation of the country's foreign reserves cannot be only attributed to such sector. Pakistan diversifies foreign reserves it Draws by many sector and sources. Some of the other sectors and sources that contribute to Pakistan's foreign reserves include:

1. Remittances: Emigrants' remittances that are acted outside of Pakistan produce a considerable proportion of Pakistan's foreign exchange reserves. These remittances that defy the USD currency are transfers by the overseas Pakistanis to their dear and near ones to support them and the economy

2. Exports of other goods and services: However, there are a lot of other commodities are contributed by Pakistan to the world trade market such as leather products, rice, grain and oil seeds, fruits, and vegetables, surgical instruments, and Information Technology services. These exports consequently finance the importation of essential raw materials and services, which bolsters the country's foreign reserves.

3. Foreign direct investment (FDI): Novel investments in different sectors of economy, for instance; telecommunications, energy, manufacturing, and services also have positive contribution in building the national reserves of Pakistan. FDI inflows entire foreign capital, technology and knowledge that in turn connects to economic expansion and development.

4. Bilateral and multilateral assistance: The IMF, World Bank, Asian Development Bank, and bilateral donors contribute in financial aid and credit from bi-lateral and multi-lateral sources. These income sources in addition to financial aid to Pakistan stabilize the foreign reserves as well and maintain the balance of payments.

1. Exports of services: Along with goods, Pakistan also procures foreign exchange through services trading of the same type, including IT outsourcing, software development, engineering services, and healthcare services.

Foreign exchange income diversification from the emergency reserves is of crucial importance for being able not to depend entirely on IMF as an external source of shocks solitude for Pakistan. However, the textile industry represents the main driver as a source of reserves, while other punches of sectors and sources make its contribution as well.

If the textile sector in Pakistan were to collapse or experience significant setbacks, the country would likely face several challenges:

Source

1. Loss of foreign exchange earnings: The factor of the depreciation of textile sector revenue from foreign trade will have a great impact on Pakistan’s foreign exchange earnings. The sharp fall of textiles, which still accounts for a substantial share of national exports along with foreign exchange reserves, would somewhat compromise the country's payments for imports and servicing of the external debt and depressive influence upon the foreign exchange rates.

2. Unemployment and poverty: The textile industry is the main source of livelihood at the national and rural level leaving less options of employment elsewhere. The decline in the textile business will result in massive job cuts leading to rising unemployment, thereby causing high-end poverty and deepening economic difficulties to the unemployed and their households.

3. Economic downturn: The acreage of the textile sector decreases may cause problems spread across the economy among decreasing economic activity, investment, and consumer demand respectively. It could be that there is a recession, [definitely], the country's GDP will decline and give more pressure on the government's finances.

4. Social unrest and instability: An acute loss of the workforce as well as domestic economic hardship may become a source of social unrest, protests and political turbulence in case of a collapse of textile industry in Pakistan. The government will have to tackle the disputes of the workers and community concerned that might plunge the country into disunity and conflict partly.

5. Loss of competitiveness: The downturn of the textile industries will possibly impair Pakistan's competitiveness in international markets due to which textile will become the substitute of Pakistani exports. Such may result in an irreversible loss of market position for Pakistani export firms and the ability to trade thereby, putting more pressure on the country's economy.
