The Indispensable Independence of Central Banks
Central banks are indispensable organizations negotiating economic instability in a world of rising tariffs, market volatility and structural issues like aging populations, growing debt, and climate change. Given how the global economic landscape right now is “fraught with uncertainties and rapid change,” according to recent research from the Bank for International Settlements (BIS), their position and function today becomes even more crucial.
With the ability to stabilize markets and protect national economies from external “exogenous” shocks, these monetary authorities, as lenders of last resort, have evolved into the primary emergency responders to economic crises. Their constantly criticized but often necessary efforts have guided economies toward recovery and repeatedly prevented financial collapse for several decades. Primary to this function – their independence.
Rather alarmingly, several political leaders across the globe today are seeking to interfere with central bank operations, pressuring them to align monetary policy with political agendas. Such interventions threaten to compromise economic stability, erode market confidence and weaken the credibility central banks need to manage inflation, employment and financial system health effectively. Preserving institutional independence is not a luxury but a necessity for sustainable, non-partisan economic management.
The Central Bank Arsenal
Monetary policy is famously a ‘blunt’ tool for central banks to achieve their targets, with interest rates the primary one used to affect economic circumstances, among several others. The main one the Fed uses to adjust the federal funds rate is interest on reserve balances, or the money banks make on money kept at their Federal Reserve bank. This system gives banks a ‘risk-free’ option and, in effect, sets a floor for interest rates in the whole economy. Additionally, open market operations and instruments such as the Overnight Reverse Repurchase Agreement Facility ensure that monetary policy is felt across the financial system by extending the central bank’s authority to a larger group of financial institutions.
Beyond the conventional, modern central banks today wield a far expanded arsenal, with the COVID pandemic providing them a dramatic platform to showcase their vital role in crisis management. Faced with “the Herculean challenge of reconciling a real economy where the clock had stopped with a financial sector where it kept ticking,” as the BIS put it, central banks all around the world came up with extraordinary solutions that extended far beyond domestic concerns.
During the crisis, these institutions “moved swiftly and forcefully to prevent a potential financial collapse from exacerbating the damage to the economy”. Financial systems were stabilized through targeted interventions in stressed market segments, such as when US money market funds experienced large-scale redemptions — approximately $160 billion or 15% of assets under management withdrawn in March 2020 alone — the Fed established facilities to backstop these funds, preventing wider market breakdown and ensuring no liquidity concerns. Similar actions were taken by several other global central banks – from the European Central Bank to the Bank of Thailand and the Reserve Bank of India, adapting their tools to address specific market dysfunctions.
Perhaps most notably, many central banks, particularly developed market ones, expanded their influence through large-scale asset purchases (“quantitative easing”). When the US Treasury market — arguably the world’s most important financial market — experienced severe volatility in March 2020, the Fed responded with massive purchases of Treasuries.
Emerging market economies were perhaps struck even harder by global market ructions and faced especially difficult obstacles. “Disruptions to global value chains and a collapse in export receipts, exacerbated by plummeting commodity prices” were the “perfect storm” these countries faced, according to the BIS. Outflows of capital “dwarfed those during previous stress episodes,” putting tremendous strain on their banking systems and currencies. EM central banks faced acute liquidity constraints, steep currency declines, and bond market sell-offs that caused rates to spike (bond prices and yields move inversely). Their actions, which ranged from foreign exchange interventions to interest rate changes, were crucial in averting total economic disaster.
As several experts have often stated, collectively, Asia has generally proved to be more resilient than the rest of the world. The aggressive actions of their central banks, which have often negotiated the difficult balance between promoting growth and preserving financial stability, are the reason.
Shielding Monetary Policy from Political Winds
One of the cornerstones of contemporary monetary governance is central bank independence. This independence “is designed to insulate the central bank from the short-term and often myopic political pressures associated with the electoral cycle,” wrote former Federal Reserve Governor Laurence H. Meyer a while ago. The logic is simple: even if long-term costs make policies undesirable, elected leaders are often motivated to provide economic advantages prior to elections or promises for the same to ensure they ascend to/remain in power. Economists refer to this as the “political business cycle,” in which pre-election stimulation raises inflation and is followed by harsh monetary constraint following the casting of ballots.
Being independent does not imply that central banks are unaccountable or subject to no restrictions: “’Independence’ does not mean literally independence from government, because central banks here and abroad are almost always part of government,” wrote Meyer. Rather, it is a carefully crafted partnership that preserves democratic legitimacy through a number of accountability systems while granting central banks operational autonomy.
It is when political pressures increase during crises that the importance of this independence is most noticeable. “The tradition of independence at the Fed, the leadership of its Chairman, the influence of long terms for governors, and the presence of Reserve Bank presidents” act as safeguards against precipitous actions at these times. The long-term economic interest is eventually served by these protections, which enable monetary authorities to take essential but somewhat unpopular decisions, such as hiking interest rates during inflationary periods.
A Delicate Balance
Despite their essential role, central banks still face several challenges and criticism both for their autonomy and operationally. Detractors claim that these entities lack democratic oversight and have excessive power. Tao Zhang of BIS noted that consistently increasing public debt levels, for example, are a serious worry: public debt was high in several nations even prior to the pandemic. Since then, it has grown even more because the significant deficits that were created at the start of the COVID-19 issue have not yet been completely eliminated. Monetary policy is particularly complicated by high debt, especially when interest rates are still high as it can raise inflationary pressures by increasing aggregate demand, which makes the process of restoring price stability even more challenging.
Uncertainty in policy itself also becomes problematic. Zhang states that “central banks are significantly impacted by such an environment of uncertainty and unpredictability.” Because households are less inclined to make large purchases and firms are less inclined to invest, it has an adverse effect on economic activity. Decisions about monetary policy must be made against this uncertain backdrop, which frequently forces central banks to make decisions with incomplete knowledge and in the face of ever-changing circumstances.

As the global risks shift, central banks must evolve. Artificial intelligence, for example, is rapidly emerging as a transformative force, poised to reshape both economies and the way central banks operate and manage their objectives. Climate change adds another layer of challenge. With more extreme weather and a global shift toward sustainable energy, central banks must account for new risks to financial stability, inflation and growth. At the same time, aging populations in advanced economies could prolong low natural interest rates and change how monetary policy affects the economy.
