The governance structure of Sri Lanka has undergone significant transformations since its independence from British rule in 1948. From a Westminster-style parliamentary system, the nation transitioned in 1978 to a unique semi-presidential model featuring a powerful executive presidency. This institutional framework has played a profound role in shaping the country’s political landscape, public policy, and fiscal performance. The central concentration of executive authority, coupled with weak legislative oversight and institutional erosion, contributed significantly to the policy missteps that led to the devastating 2022 macroeconomic collapse. Following the historic mass protests of the 2022 "Aragalaya" movement, Sri Lanka embarked on a wave of constitutional and legislative reforms. This article provides a comprehensive analysis of Sri Lanka's government structure, examining the semi-presidential system, the legislative powers of Parliament, the historical struggle for Central Bank independence, the challenges of regional devolution, and the post-crisis governance and anti-corruption reforms aimed at rebuilding state institutions. These institutional developments are critical to understanding how Sri Lanka can overcome its historical fiscal deficits and build a more stable economic future.
Sri Lanka’s governance is defined by its 1978 Constitution, which established a semi-presidential system. This system is a hybrid that combines elements of both the French presidential model and the British parliamentary model. Under this constitution, the President of Sri Lanka is the head of state, head of the executive, and commander-in-chief of the armed forces. The President is directly elected by the public for a five-year term and possesses extensive powers, including the authority to appoint the Prime Minister, appoint cabinet ministers, and dissolve Parliament under specific constitutional conditions. The core characteristic of this system has been the concentration of immense executive power in a single office, often described as an "imperial presidency." While the system was designed to provide political stability and decisive executive decision-making to facilitate economic development, it has frequently led to executive overreach, the bypass of cabinet consensus, and the marginalization of parliamentary oversight. The shifting balance of power has been a recurring political struggle, leading to a sequence of constitutional amendments that alternated between strengthening the presidency (such as the 18th and 20th Amendments) and restoring democratic checks and balances (such as the 17th, 19th, and 21st Amendments).
Despite the dominance of the executive presidency, the Parliament of Sri Lanka remains the supreme legislative body. It is a unicameral legislature consisting of 225 members elected for five-year terms through a system of proportional representation. The primary functions of Parliament are lawmaking, public debate, and fiscal oversight. Under the Constitution, Parliament has absolute control over public finance, including the power to approve the annual budget, authorize government expenditures, and levy taxes. Parliament exercises this oversight through several specialized committees, most notably the Committee on Public Accounts (COPA), the Committee on Public Enterprises (COPE), and the Committee on Public Finance (COPF). However, in practice, parliamentary oversight of public finance has historically been weak and highly politicized. The executive’s ability to offer ministerial portfolios and patronage to members of Parliament has often enabled the President to secure a loyal majority, reducing Parliament to a rubber-stamp body for executive-driven fiscal policies. The failure of Parliament to challenge the unsustainable tax cuts of 2019 and the subsequent rise in public debt highlighted the limitations of legislative oversight and the need for structural reforms to empower independent committees. The inability of legislative institutions to block these reckless fiscal measures directly contributed to the catastrophic sovereign default of 2022.
The dual executive structure of the President and the Prime Minister has occasionally led to institutional conflict and governance paralysis, particularly during periods of "cohabitation" where the President and the Prime Minister belonged to opposing political parties. The Prime Minister is appointed by the President from among the members of Parliament and must command the confidence of the legislature. The Prime Minister serves as the leader of the government in Parliament and assists the President in coordinating the cabinet. When the President and the parliamentary majority are aligned, the Prime Minister functions primarily as a deputy, implementing the President's policy agenda. However, when they are politically opposed, the constitutional ambiguities regarding executive control have led to severe institutional friction. For example, during the cohabitation government of 2015-2019, the rivalry between President Maithripala Sirisena and Prime Minister Ranil Wickremesinghe resulted in administrative paralysis, a breakdown in security cooperation that contributed to the 2019 Easter Sunday bombings, and inconsistent economic policy. This highlights the inherent instability of the semi-presidential hybrid when robust institutional norms are lacking.
The institutional relationship between the Central Bank of Sri Lanka (CBSL) and the government has been a critical factor in the nation’s economic history. Established in 1950, the CBSL was historically governed by the Monetary Law Act (MLA), which placed the bank under the significant influence of the Ministry of Finance. A representative of the Ministry of Finance sat directly on the Monetary Board, the governing body of the bank, effectively compromising its monetary policy independence. This lack of autonomy allowed successive governments to pressure the CBSL to finance fiscal deficits through the purchase of government securities (commonly known as money printing). This practice fueled chronic inflation, depleted foreign exchange reserves, and ultimately contributed to the 2022 debt default. In response to these systemic failures, Sri Lanka enacted the new Central Bank Act in September 2023 as part of its IMF-supported restructuring program. The landmark legislation formally established the CBSL's autonomy, removing the Ministry of Finance representative from the governing boards and prohibiting the direct purchase of government debt in the primary market. The Act redefined the primary objectives of the CBSL as maintaining domestic price stability (inflation targeting) and financial system stability, while creating a transparent framework for monetary policy decisions, thereby seeking to build market confidence and prevent future politicization of monetary policy.
Sri Lanka is administratively divided into nine provinces, each governed by a Provincial Council. The system of provincial councils was established under the 13th Amendment to the Constitution in 1987, following the signing of the Indo-Sri Lanka Accord. The amendment was intended to resolve the ethnic conflict by devolving administrative and legislative powers to the provinces, particularly the Tamil-majority Northern and Eastern provinces. Under the 13th Amendment, powers are divided into three lists: the Provincial Council List (devolved powers), the Reserved List (retained by the central government), and the Concurrent List (shared powers). Provincial councils have authority over subjects such as regional planning, local government, provincial roads, and social services. However, the devolution of power has remained a highly controversial and incomplete process. Central governments of various political leanings have consistently resisted devolving critical powers, particularly land and police powers, to the provinces. Financial dependency is also a major issue, as provincial councils have limited revenue-generating capabilities and rely heavily on block grants from the central government. This fiscal centralization has restricted the ability of provincial administrations to foster regional economic development and attract vital foreign direct investment to less-developed areas.
The culmination of decades of economic mismanagement, systemic corruption, and political centralization triggered a historic public uprising in early 2022. Known as the "Aragalaya" (the Sinhala word for "Struggle"), the movement was a decentralized, non-partisan mass protest campaign that mobilized millions of citizens across diverse ethnic, religious, and class backgrounds. The protests were sparked by the daily hardships of 13-hour power cuts, skyrocketing food prices, and acute shortages of fuel, cooking gas, and lifesaving medicines. Protesters occupied public spaces, including the iconic Galle Face Green in Colombo, demanding the resignation of President Gotabaya Rajapaksa and his powerful family members who held key cabinet positions. The Aragalaya achieved unprecedented political outcomes. It forced the resignation of Prime Minister Mahinda Rajapaksa in May 2022, followed by the dramatic flight and resignation of President Gotabaya Rajapaksa in July 2022. Beyond demanding immediate regime change, the movement articulated a profound demand for "system change," calling for the abolition of the executive presidency, greater political accountability, anti-corruption measures, and a more equitable distribution of wealth. This movement was deeply influenced by the historic civil war legacy which had reinforced authoritarian tendencies in governance.
Following the political transition of 2022, the government led by newly appointed President Ranil Wickremesinghe faced the dual challenge of economic stabilization and governance reform. To address the deep-seated institutional decay identified during the crisis, the government enacted several major legislative reforms, largely aligned with the recommendations of the IMF's landmark Governance Diagnostic Assessment—the first such assessment conducted by the IMF in an Asian country. A key reform was the passage of the 21st Amendment to the Constitution, which restored several checks on the executive presidency. The amendment re-established the Constitutional Council, an independent body responsible for recommending appointments to key public commissions, such as the Election Commission, the National Police Commission, and the Commission to Investigate Allegations of Bribery or Corruption (CIABOC). Furthermore, Parliament passed the Anti-Corruption Act in July 2023, which significantly strengthened the legal framework to combat bribery and public corruption. The Act enhanced the powers and independence of CIABOC, introduced stringent asset declaration requirements for public officials (including the President and members of Parliament), and established a comprehensive framework for international cooperation in asset recovery.
In addition to anti-corruption legislation, the post-Aragalaya reform agenda has focused on enhancing public financial management (PFM) and fiscal transparency. Historically, Sri Lanka's budget formulation and execution were marred by off-budget spending, lack of public disclosure, and unchecked tax concessions granted to politically connected businesses. To ensure that the massive defense expenditure of the country is also subject to democratic scrutiny, PFM reforms have aimed to cover all state sectors. To address these vulnerabilities, the government has worked to implement a new Public Financial Management Act. This legislation aims to introduce legally binding fiscal rules, such as capping the government's budget deficit and public debt-to-GDP ratio, and establishing strict penalties for government departments that exceed their authorized budgets. The state has also launched online portals to publish tax concession registers, major procurement contracts, and list of public officials who fail to file asset declarations. While these measures represent significant progress, the effectiveness of these reforms depends entirely on their consistent enforcement, the political will of future administrations, and the active vigilance of civil society and independent media.
The government structure of Sri Lanka is in a state of transition, caught between the legacy of an authoritarian executive presidency and the urgent necessity of democratic, transparent governance. The historical concentration of executive power under the 1978 Constitution facilitated the policy errors that caused the 2022 economic collapse, revealing the profound danger of bypassing institutional checks and balances. The 2022 Aragalaya movement served as a powerful catalyst for change, forcing political elites to concede major legislative reforms. The establishment of Central Bank autonomy through the Central Bank Act of 2023, the restoration of independent commissions under the 21st Amendment, and the passage of the Anti-Corruption Act represent major milestones toward building a resilient state. However, the true test of these reforms lies in their implementation. Sri Lanka's path to sustainable economic development and financial stability is fundamentally linked to its ability to institutionalize these reforms, ensuring that public finance remains subject to rigorous legislative oversight, independent monetary authority, and uncompromising public accountability.
