Recent data shows rising monetary support, although current conditions do not yet point to a clear market reversal or sustained bullish momentum.Federal Reserve Balance Sheet Expands AgainA recent update shared by CryptoGoos noted that the Federal Reserve balance sheet increased by $18 billion in one week. The total now stands at $6.675 trillion and continues to expand steadily. This shift follows the end of quantitative tightening in 2025, marking a return to balance sheet growth.LIQUIDITY IS COMING BACK INTO THE MARKETThe Fed balance sheet just expanded by $18 billion in a single week.The Fed's balance sheet is now at $6.675 trillion and expanding.QT officially ended in 2025, and the Fed started growing it again.The balance sheet never fully… pic.twitter.com/Zuo9aBww0k— CryptoGoos (@cryptogoos) April 4, 2026The data shows that the Fed never fully reversed its pandemic-era expansion. Instead, it stabilized at a higher baseline level. That baseline is now rising again, reflecting renewed liquidity entering the system. While this growth signals easing financial conditions, it remains controlled rather than aggressive.At the same time, short-term Treasury bill purchases are running at $381 billion. This level exceeds activity seen during the 2020 crisis period. Such elevated buying suggests continued demand for short-term liquidity tools. It also shows that policymakers are maintaining support for market stability.However, the nature of these actions matters. The current expansion does not involve large-scale purchases of long-term bonds. Without that, the effect on broader financial markets may remain limited. Liquidity is present, yet it is not being deployed in a way that drives strong upward momentum.Treasury Buyback Adds Support to Bond MarketsAlongside Federal Reserve activity, the U.S. Treasury recently completed a $15 billion debt buyback. This operation, finalized on April 2, 2026, marks the largest single buyback ever recorded. The move aimed to improve liquidity in the bond market and support smoother functioning.According to the tweet, the buyback injected funds directly into the system. This helped stabilize conditions in the Treasury market, where liquidity can tighten during periods of uncertainty. By purchasing existing debt, the Treasury effectively increased cash flow within financial markets.Even so, broader conditions remain mixed. The tweet notes that uncertainty across markets is still elevated. This limits the ability of liquidity injections to translate into sustained upward price action. Stability may improve, but confidence remains uneven.Two key factors are still missing for a stronger market shift. There is no clear reduction in macro uncertainty at present. In addition, the Federal Reserve is not actively buying long-term bonds. These elements often play a central role in driving major market cycles.As a result, current measures may help hold markets in place rather than push them higher. Liquidity is returning, yet it is not at levels or forms that typically trigger a full bull run. For now, the system appears supported, though not positioned for a rapid reversal.The post Fed Balance Sheet Expands as Treasury Buyback Adds Liquidity but Bull Run Lags appeared first on Blockonomi.
