A growing debate is unfolding inside the Federal Reserve and across Wall Street over whether regulatory changes aimed at easing liquidity requirements for banks could allow the central bank to significantly reduce its massive balance sheet, though many policymakers remain skeptical that the cuts envisioned by new Fed Chair Kevin Warsh can realistically be achieved.
The discussion has intensified since Warsh took over leadership of the Federal Reserve, bringing renewed attention to the central bank’s enormous $6.7 trillion portfolio of Treasury and mortgage-backed securities accumulated over years of economic crises and aggressive monetary stimulus programs.
Warsh, who previously served as a Federal Reserve governor during the 2007-2009 financial crisis, has long expressed concerns that the Fed’s oversized balance sheet distorts financial markets and weakens the effectiveness of traditional interest rate policy.
Although he did not formally oppose the original emergency asset purchases implemented during the financial crisis or subsequent rounds of quantitative easing, his resignation from the Fed in 2011 was widely viewed by analysts as reflecting his discomfort with the central bank’s growing reliance on large-scale bond-buying programs.
Now, as Fed chair, Warsh appears eager to explore ways to reduce the central bank’s footprint in financial markets and restore a leaner operating framework. However, many inside the Federal Reserve question whether today’s financial system can function with anything close to the smaller balance sheet the central bank maintained before the global financial crisis.
Analysts at BNP Paribas recently estimated that a series of regulatory reforms could potentially lower banks’ demand for reserves by roughly $700 billion from current levels.
The changes under discussion would likely take years to implement and involve adjustments to how banks satisfy liquidity requirements imposed after the financial crisis.
Among the proposals being examined are allowing banks to count Federal Reserve discount window borrowing capacity toward regulatory liquidity requirements, expanding central clearing for Fed repurchase agreement operations and upgrading certain agency and mortgage-backed securities to the highest-quality liquidity category.
Supporters of the reforms argue that such changes would reduce the amount of cash and reserves banks feel compelled to hold, thereby allowing the Federal Reserve to shrink its balance sheet further without destabilizing financial markets.
Some policymakers and economists also believe more active use of the Fed’s repo facilities, which provide emergency short-term funding to financial institutions, could allow banks to operate safely with lower reserve levels.
Still, significant skepticism remains among senior Federal Reserve officials regarding how much the balance sheet can realistically be reduced under the modern financial system.
Christopher Waller said recently that returning to the small pre-crisis balance sheet maintained before 2008 is no longer feasible because of the way financial markets and banking regulations have evolved over the past two decades.
“There’s no way you can go back to the small balance sheet we had” before the financial crisis, Waller said during recent remarks discussing the issue.
He acknowledged that the Fed is studying possible regulatory adjustments that could modestly lower reserve demand over time. However, he cautioned that even optimistic scenarios would likely produce only limited reductions in the central bank’s overall holdings.
According to Waller, changes to liquidity regulations might reduce reserve levels by between $300 billion and $500 billion. Even then, he said the Federal Reserve’s balance sheet would likely remain above $6 trillion.
“It’s just not likely to go down very much,” he said.
The debate reflects broader questions about how the Federal Reserve should operate after years of extraordinary intervention in financial markets.
Before the 2008 financial crisis, the Fed’s balance sheet stood below $1 trillion and the central bank managed interest rates primarily through relatively small market operations.
That changed dramatically during the financial crisis, when the Fed began purchasing massive amounts of Treasury securities and mortgage-backed bonds to stabilize financial markets and support economic growth.
The central bank expanded those programs again during the COVID-19 pandemic, pushing total holdings to nearly $9 trillion by mid-2022 as policymakers attempted to prevent economic collapse and maintain liquidity throughout the financial system.
The massive expansion fundamentally transformed how the Federal Reserve manages short-term interest rates and interacts with financial institutions.
Beginning in 2022, the Fed started gradually reducing its holdings as part of a broader effort to tighten monetary policy and combat inflation. By the end of 2025, the balance sheet had declined to around $6.5 trillion before modestly increasing again in an effort to maintain stable liquidity conditions and preserve firm control over interest rates.
Under the current operating framework, the Federal Reserve faces practical limits on how much liquidity it can remove from the financial system without risking disruptions in money markets or losing control over its policy rate.
That reality has complicated Warsh’s efforts to pursue a substantially smaller balance sheet and sparked growing internal debate over how aggressively the Fed should attempt to reduce its market presence.
Critics of the Fed’s large balance sheet argue that the central bank’s heavy involvement in bond markets artificially suppresses yields, distorts asset prices and encourages excessive risk-taking by investors.
Warsh has repeatedly voiced concerns that reliance on balance sheet tools weakens the Fed’s traditional interest rate policy mechanism and increases the risk of market dependence on central bank intervention.
However, supporters of the current framework argue that the post-crisis financial system now depends on higher reserve levels and more robust liquidity protections to maintain stability during periods of stress.
Some economists and regulators also worry that relaxing bank liquidity rules at a time when the Federal Reserve is already scaling back portions of its regulatory oversight could create new vulnerabilities within the financial system.
Those concerns have become more pronounced as policymakers attempt to balance efforts to improve market efficiency with the need to guard against future banking crises or liquidity shocks.
In recent months, Federal Reserve officials, economists and academics have increasingly discussed alternative approaches that could gradually reduce reserve demand while preserving financial stability.
Still, analysts say achieving Warsh’s long-standing goal of dramatically shrinking the Fed’s balance sheet may prove politically and technically difficult given how deeply the current financial system has adapted to abundant central bank liquidity.
The debate is expected to remain a major issue for the Federal Reserve in the coming years as policymakers continue reassessing the legacy of the post-crisis monetary framework and the central bank’s evolving role in global financial markets.
