Prime Minister Narendra Modi completes 12 uninterrupted years in office on June 11, 2026, marking a political milestone few leaders in independent India have achieved.Since first taking oath on May 26, 2014, Modi has led three consecutive governments, overseeing a period marked by major economic reforms, constitutional changes, welfare expansion, technological transformation, national-security shifts and an increasingly assertive foreign policy.Also Read: 12 years of PM Modi: India should not only be resilient but also be antifragileOver the past decade, India has witnessed developments ranging from demonetisation and GST to the abrogation of Article 370, the rise of UPI, the construction of Ram Mandir in Ayodhya, the rollout of large-scale welfare schemes and a significant repositioning of the country's global role.Together, here are 12 developments that came to define the Modi era:DemonetisationFew decisions generated as much nationwide attention as the government's demonetisation announcement on November 8, 2016.In a nationally televised address, Modi declared that ₹500 and ₹1,000 notes would cease to be legal tender from midnight of that same day. The move was presented as an assault on black money, counterfeit currency and terror financing.The Reserve Bank of India introduced redesigned ₹500 notes and a new ₹2,000 denomination to restore liquidity. Later, in May 2023, the RBI also withdrew the ₹2,000 notes under its Clean Note Policy.Goods and Services TaxIf demonetisation was the most dramatic economic intervention, the Goods and Services Tax was arguably the most ambitious structural reform.Launched on July 1, 2017, GST replaced a complicated web of central and state levies with a unified indirect tax system.Also Read: 12 years of PM Modi about restoring India's pride: Amit ShahBefore GST, businesses navigated multiple taxes including excise duty, service tax, value-added tax, entry tax and octroi. The new framework sought to create a single national market and reduce cascading taxation. GST gradually evolved through repeated council meetings and revisions.The most significant reform came on September 6, 2025, when the GST Council approved a major rationalisation exercise.The council effectively simplified the tax structure by removing the 12 per cent and 28 per cent slabs for most products and retaining two principal rates of 5 per cent and 18 per cent. At the same time, a 40 per cent rate was imposed on luxury and “sin goods”.Operation SindoorOperation Sindoor marked a defining moment in India's national security posture.Launched in the early hours of May 7, 2025, weeks after the Pahalgam terror attack that killed 26 civilians, Operation Sindoor was India's most expansive cross-border military action in decades.The operation targeted nine terror facilities across Pakistan and Pakistan-occupied Kashmir, including strongholds linked to Jaish-e-Mohammed, Lashkar-e-Taiba and Hizbul Mujahideen.Also Read: India emerges as global tech partner under PM Modi's 12-yr tenure, exporting to US, China: VaishnawWhat set Operation Sindoor apart was not just the targets but the message. India struck deep inside Pakistani territory, including military installations and air bases such as Chaklala, Rafiqui, Nur Khan and Rahim Yar Khan, signalling that geographical depth would no longer guarantee immunity.A year later, Operation Sindoor is increasingly viewed as a watershed moment in India's security doctrine — one that signalled a willingness to strike beyond traditional boundaries, leverage integrated military capabilities and respond to terrorism with speed, precision and strategic restraint.Insolvency and Bankruptcy CodeFor decades, India's financial system struggled with what economists described as the "twin balance sheet problem" — heavily indebted corporations and banks burdened by bad loans.The Insolvency and Bankruptcy Code (IBC), enacted in 2016, sought to break that cycle.The reform fundamentally changed the balance of power between borrowers and lenders. For the first time, defaulting promoters faced the realistic prospect of losing control of their companies if debts remained unpaid.Instead of allowing cases to drag on for years across multiple legal forums, IBC introduced a structured and time-bound resolution process.By March 2026, creditors had realised more than ₹4 lakh crore through resolution plans, as per a PIB release. Thousands of cases were settled even before admission as promoters sought to avoid insolvency proceedings altogether.Government estimates suggest that more than ₹14 lakh crore worth of disputes were resolved or avoided through pre-admission settlements.The banking system also underwent a transformation. Gross non-performing assets, which had climbed to nearly 11.8 per cent in 2017, fell to around 2.1 per cent by September 2025.Revocation of Article 370 and reorganisation of J&KOn August 5, 2019, the government carried out one of the most consequential constitutional changes in modern India.Article 370, which granted special status to Jammu and Kashmir, was effectively revoked. The state was simultaneously reorganised into the Union Territories of Jammu and Kashmir and Ladakh.The issue eventually reached the Supreme Court.On December 11, 2023, a Constitution Bench upheld the government's decision.The government has since argued that the change has improved governance, expanded investment opportunities and accelerated infrastructure development in the region.Ram Mandir constructionFew issues have shaped India’s political landscape as deeply as the Ram Janmabhoomi movement. At the centre of the dispute was a site in Ayodhya in Uttar Pradesh regarded by many Hindus as the birthplace of Lord Ram, where the 16th-century Babri Masjid stood.The issue escalated over decades and reached a turning point on December 6, 1992, when the mosque was demolished by kar sevaks.In November 2019, the Supreme Court awarded the disputed land for a Ram temple and ordered a separate five-acre plot for a mosque. Modi attended the bhoomi pujan on August 5, 2020, while the Ram Mandir consecration was held on January 22, 2024.Construction of the main temple was completed on November 25, 2025, marking the culmination of a movement that had influenced Indian politics for generations.Unified Payments Interface launchIf one reform touched the daily lives of Indians more visibly than any other, it was the rapid expansion of digital public infrastructure.Built around the Jan Dhan-Aadhaar-Mobile framework, the government's digital architecture transformed everything from welfare delivery to financial transactions.At the centre of this transformation stood the Unified Payments Interface (UPI), launched in April 2016.By 2025, India accounted for roughly half of global digital transaction volume through UPI, as per the government. In May 2026 alone, the platform processed transactions worth ₹29.9 lakh crore.Welfare delivery The Modi years saw wider use of direct benefit transfers, foodgrain distribution and farmer welfare schemes. At the centre of this effort was the Pradhan Mantri Garib Kalyan Anna Yojana (PMGKAY), launched during the Covid-19 pandemic to cushion vulnerable households from economic disruption.Initially rolled out as an emergency relief measure, the scheme evolved into the world's largest food security programme, as per a PIB release, providing free foodgrains to beneficiaries covered under the National Food Security Act (NFSA), as per the government.From January 2023, the Centre began providing foodgrains free of cost to all eligible beneficiaries under the NFSA. In 2024, the programme was extended for another five years, with the government committing an estimated ₹11.8 lakh crore towards its implementation.Nearly 80 crore people now receive subsidised or free foodgrains through the country's public distribution network.The focus in agriculture also widened during this period through schemes related to income security, productivity, market access and resilience. Programmes such as PM-KISAN, PM Fasal Bima Yojana, PM Krishi Sinchayee Yojana and the Agriculture Infrastructure Fund were among the key initiatives introduced or expanded during the period.Production Linked Incentive schemeThe Production Linked Incentive (PLI) scheme was first launched in April 2020 to encourage domestic manufacturing across multiple sectors.Implemented across 14 sectors, including electronics, pharmaceuticals, telecom equipment, automobiles, batteries, solar modules, textiles and drones, the programme seeks to reward incremental production and investment.By December 2025, PLI schemes had attracted investments exceeding ₹2.16 lakh crore, as per the PIB.PLI formed part of a broader manufacturing push that also included Make in India, industrial corridors, logistics reforms, labour-law rationalisation and the PM Gati Shakti infrastructure programme.Corporate tax cutsAs economic growth slowed in 2019, the government unveiled one of the most significant tax reductions in India's corporate history.Under reforms announced in September 2019, domestic companies were allowed to opt for a concessional tax rate of 22 per cent provided they did not avail exemptions or incentives.The effective tax rate for such firms stood at 25.17 per cent including surcharge and cess.New domestic manufacturing companies incorporated on or after October 1, 2019, were offered a tax rate of 15 per cent, translating to an effective rate of 17.01 per cent.The move was widely viewed as a signal to investors about India's economic priorities.Income tax overhaulWhile corporate tax reform targeted businesses, the government's 2025 income-tax changes focused on households.Presenting the Union Budget on February 1, 2025, Finance Minister Nirmala Sitharaman announced a major revision of the new tax regime.Under the revised framework, individuals earning up to ₹12 lakh annually under the new tax regime were exempted from income tax, while salaried taxpayers benefited from a higher effective threshold after standard deductions.The changes formed part of a broader effort to simplify the tax structure and increase disposable income.Trade agreementsTrade policy became increasingly central to India’s economic strategy during the Modi years, with New Delhi accelerating efforts to secure preferential market access and diversify exports.According to trade think tank Global Trade Research Initiative (GTRI), India currently has 15 operational free trade agreements (FTAs) covering 27 countries, while nine more involving 42 countries are awaiting implementation, nearing completion or under negotiation. Together, these markets account for more than three-fourths of India’s exports and nearly two-thirds of imports.India signed a FTA with the United Kingdom on July 24, 2025, while another agreement with Oman became operational on June 1, 2026. Negotiations are also underway with Australia, Sri Lanka, Peru, Chile, Israel, the Eurasian Economic Union, where both sides announced a framework for an interim Bilateral Trade Agreement in February 2026.The government has also concluded negotiations with the European Union and New Zealand, while discussions continue on a broader trade framework with the United States.Foreign policy and national securityPerhaps the broadest transformation of the Modi years has been India's changing place in the world.Since 2014, New Delhi has deepened strategic partnerships with the United States, France, the European Union, Japan, Australia, the UAE and Saudi Arabia while maintaining long-standing ties with Russia.The evolution of the "Look East" policy into "Act East" signalled a more proactive regional strategy.The revival of the Quad in 2017 placed India at the centre of emerging Indo-Pacific discussions on maritime security, supply chains, critical technologies and cybersecurity.India's G20 presidency in 2023 further elevated its diplomatic profile.By securing consensus on the New Delhi Leaders' Declaration and championing the Voice of Global South initiative, India positioned itself as a bridge between advanced economies and developing nations.The period also saw the announcement of the India-Middle East-Europe Economic Corridor, a proposed connectivity project linking India with the Gulf and Europe.Taken together, developments of the past 12 years reshaped several aspects of India’s economic, political and strategic landscape. The period was marked by policy shifts, large-scale state interventions and a changing global profile, with many of the outcomes still unfolding.
