In a remarkable twist of events in 2024, global financial markets have defied expectations, witnessing a substantial surge in stock prices despite central banks worldwide withdrawing liquidity from the financial systemThis phenomenon has led market analysts and investors to ponder an intriguing question: If the reduction of liquidity did not pose a significant barrier to market performance this year, could a potential improvement in liquidity conditions next year serve as a favorable tailwind for the markets? As eyes turn toward the future, projections indicate that economic growth may be experiencing a slowdown, partly due to rising uncertainties surrounding U.Strade policies, while major economies like China, Europe, and Canada are expected to adopt more accommodative monetary policies.

The Federal Reserve has begun to cut interest rates and may gradually finish its quantitative tightening (QT) program, which has been in place since the middle of 2022 and resulted in a reduction of the Fed's balance sheet by $2 trillion

In simpler terms, the trend of diminishing liquidity could very well see a reversal, easing the constraints on investment markets that many had braced for.

However, evaluating the impact of liquidity on asset prices presents its own challenges, primarily because tracking liquidity levels in financial markets and the global banking system can be complexLiquid conditions are commonly assessed through the scale of central bank balance sheetsThis, notwithstanding its somewhat blunt approach, operates on the premise that a larger balance sheet—particularly with high levels of bank reserves—typically correlates with robust stock market performance.

For example, a model from Citigroup analysts suggests that every $100 billion change in bank reserves held by the Federal Reserve equates to a movement of approximately 1% in the S&P 500 indexBy this measure, given the reduction of reserves by roughly $200 billion this year, Wall Street theoretically should have faced a 2% downturn

Yet, on a global scale, the 12-month change in bank reserves stands at approximately $600 billion, implying a more significant decline in global marketsIn reality, though, the S&P 500 has demonstrated a nearly 30% increase year-to-date, while the MSCI World Index has risen by 20%—figures that might have seemed improbable just a year ago.

Adding another layer of complexity, the total balance sheet size of the "G4" central banks—the Federal Reserve, the European Central Bank, the Bank of England, and the Bank of Japan—decreased by $2.2 trillion in both 2022 and 2023. Nevertheless, after a tumultuous 20% drop in global stock markets the prior year, these same markets rebounded by 20% in the following yearSuch dynamics underscore the notion that liquidity is just one of myriad factors influencing marketsElements such as economic growth, geopolitical tensions, technological advancements, earnings reports, regulatory policies, and investor sentiment each play significant roles in the daily ebb and flow of financial performance.

Yet, this does not imply that investors can completely overlook changes in liquidity

Monitoring bank reserves continues to be vital when assessing the implicit liquidity conditions within central bank balance sheetsInsufficient reserves could trigger a spike in money market rates, escalate fears of credit tightening, and lead to a sell-off of risk assets by investors wary of an uneven financial landscape.

Currently, U.Sbank reserves rest at roughly $3.2 trillion, a level regarded as "ample," though the Federal Reserve is targeting a recalibration of reserves to what is deemed "adequate." This rebalancing is precisely what the ongoing balance sheet reduction program aims to achieve.

Policymakers can take some comfort in the fact that, thus far, the interest rate cuts have not notably disrupted the financial marketsAs Janet Yellen, the U.STreasury Secretary, insightfully remarked, observing these adjustments is akin to “watching paint dry.” However, the potential for market volatility looms, particularly as 2025 approaches, compelling the Fed to reconsider its quantitative tightening efforts.

This newly emphasized landscape becomes even more pronounced with the U.S

debt ceiling issue resurfacing and the cash levels within the Fed's Overnight Repurchase Agreement (RRP) possibly approaching zero, both of which could indicate the erosion of what some Fed officials have deemed "excess" liquidityAnalysts at Goldman Sachs anticipate a halt to the Fed's quantitative tightening policies in the second quarter, although some believe this could transpire even sooner.

The proportions of the central bank balance sheets of the Federal Reserve, the European Central Bank, and the Bank of England relative to their GDP are currently at the lowest levels since early 2020, prior to the pandemicDavid Zervos, Chief Market Strategist at Jefferies, predicted back in February that quantitative tightening would cease once the Fed's balance sheet reached $7 trillionPresently, the balance sheet is approaching this threshold.

Zervos emphasized, “This is a massive balance sheet…a substantial stimulus
