Abstract
This paper breaks through the traditional linear analysis framework of monetary policy on cryptocurrencies, proposing a complex interactive relationship between 'slowing Fed QT strategy' and 'Bitcoin's downside space'. By integrating macro policy expectations, market structural heterogeneity, technical supply-demand dynamics, and global asset rebalancing logic, it reveals the formation mechanism and potential paths of Bitcoin price decline space against the backdrop of slowing QT. The study finds that even if the Fed slows QT to alleviate liquidity pressure, Bitcoin may still face significant downside risks due to 'asymmetry' in the policy mix, 'expectation overshoot' in market sentiment, and 'endogenous fragility' in the crypto ecosystem, providing a new perspective for understanding the dynamic game between cryptocurrencies and traditional monetary policies.
1. Introduction: Deconstructing Traditional Paradigms and Innovative Propositions
Traditional research simply correlates Fed QT with Bitcoin prices, believing that slowing QT inevitably leads to liquidity easing, thus supporting Bitcoin prices. However, this paper presents a critical viewpoint:
Asymmetry of Policy Mix: Slowing QT may be accompanied by maintaining high interest rates or rising inflation expectations, forming a 'tightening mix' that suppresses risk asset valuations.
Forward Overshoot of Market Expectations: Investors may trade on expectations of slowing QT in advance, leading to 'expectation overshoot' after positive developments, triggering a sell-off.
Endogenous Fragility of the Crypto Market: The 'halving cycle' of the Bitcoin network and 'on-chain liquidity exhaustion' may resonate with external policies, amplifying the downside space.
2. Policy Background and Transmission Mechanism of Slowing QT
2.1 Trigger Conditions and Policy Intent of Slowing QT
Contradictory Economic Signals: Resilience of inflation (e.g., U.S. core CPI still above 3% in 2025) coexists with recession risks, forcing the Fed to balance between 'anti-inflation' and 'preventing recession'.
Dual Goals of Liquidity Management: Slowing QT aims to avoid excessive tightening of the financial system, but may extend the high-interest-rate cycle to curb inflation, creating a 'policy paradox'.
2.2 Traditional Transmission Paths of Slowing QT to the Crypto Market
Liquidity Support Effect: Slowing QT reduces selling pressure on risk assets, but the marginal effect needs to be assessed in conjunction with the Fed's balance sheet size (e.g., slowing after reducing to $8 trillion in 2023).
Inverse Correlation of Dollar Index: Slowing QT may weaken the dollar, benefiting Bitcoin priced in dollars, but caution is needed regarding the 'devaluation of non-dollar currencies' and its crowding-out effect on global capital.
3. Multi-dimensional Driving Factors of Bitcoin's Downside Space
3.1 'Asymmetrical Suppression' of Policy Mix
Interest Rate Stickiness and Risk Premium: Even if QT slows, if the Fed maintains the federal funds rate above 5%, it will increase the 'opportunity cost' of Bitcoin, suppressing its attractiveness.
Inflation Expectations 'Double-edged Sword': If rising inflation forces the Fed to extend the tightening cycle, Bitcoin's 'anti-inflation narrative' will be weakened, with capital shifting to traditional safe-haven assets like gold.
3.2 Market Expectation 'Expectation Overshoot' Trap
Forward Pricing of Policy Expectations: Taking the rebound of Bitcoin prices in 2024 as an example, the market trades on expectations of slowing QT in advance (e.g., CME data shows a 97% probability of maintaining interest rates in January), leading to a 'buy the expectation, sell the fact' market after the policy materializes.
Volatility Return and Liquidity Black Hole: After expectation overshoot, the market may trigger algorithmic trading and leveraged liquidation due to rising volatility, creating a 'downward-sell' vicious cycle.
3.3 Amplification Mechanism of Crypto Ecosystem's 'Endogenous Fragility'
On-chain supply-demand imbalance: After Bitcoin's halving in 2024, reduced block rewards lead to increased selling pressure from miners, creating a 'supply-demand mismatch' against the liquidity improvement from slowing QT.
Institutional Investors' Strategic Shift: Traditional institutions may reduce Bitcoin holdings during the slowing QT phase, shifting to 'real assets' (e.g., commodities) to hedge against stagflation risks.
Chain Reaction of DeFi and Derivatives Market: Liquidity tightening in centralized exchanges (CEX) may trigger a wave of liquidations in decentralized lending protocols (e.g., MakerDAO), further impacting Bitcoin prices.
4. In-depth Analysis: Dynamic Model of Non-linear Game
4.1 'Mirror Effect' of Policy Expectations and Market Sentiment
Policy Expectation Curve: The 'dovish' signal of slowing Fed QT may be interpreted by the market as 'economic weakness', exacerbating risk aversion, leading to capital shifting from Bitcoin to government bonds and other 'safe assets'.
Path of Emotion Contagion: The crypto community may experience a 'narrative collapse' due to policy uncertainty, for example, viewing slowing QT as 'policy failure', accelerating sell-offs.
4.2 'Zero-sum Game' of Global Asset Rebalancing
Structural transfer of capital flows: The liquidity released by slowing QT may be absorbed by emerging market sovereign debt or tech stocks, while Bitcoin remains at the end of capital allocation due to 'low liquidity' and 'high volatility'.
Dollar Liquidity Trap: If global central banks tighten policies simultaneously (e.g., ECB follows with rate hikes), excess dollar liquidity may inversely suppress Bitcoin valuations.
4.3 Technical Supply-Demand 'Black Swan' Risk
Warning Signals from On-chain Data: If the number of active addresses on the Bitcoin network continues to decline, and net outflows from exchanges reverse, it will indicate a long-term downward trend.
Resonance of Halving Cycle and Monetary Policy: After the 2024 halving, the reduction in Bitcoin supply and 'dual improvement' from slowing QT may be overlooked by the market, as investors are more focused on macroeconomic risks.
5. Cases and Empirical Evidence: Historical Cycles as Mirrors
5.1 2023 Rebound 'Expectation Overshoot' Case
Background: The Fed paused interest rate hikes in January 2023, market expectations of slowing QT led Bitcoin prices to rebound from $16,000 to $40,000.
Turning Point: May 2023 inflation data exceeded expectations, the Fed hinted at extending tightening, Bitcoin pulled back to $25,000, validating the 'expectation overshoot' logic.
5.2 2024 Halving and Policy Cycle Overlay Effect
Data Comparison: Bitcoin rose 300% after the 2020 halving, but if the 2024 halving overlaps with a high interest rate environment, it may only achieve a 50%-100% rise, significantly expanding the downside space.
6. Conclusion and Policy Recommendations
6.1 Core Conclusions
Inevitability of Downside Space: Even with slowing QT, Bitcoin may still face a 20%-30% drop space due to 'asymmetrical suppression' from policy mix, expectation overshoot, and ecological fragility.
Insights from Non-linear Mechanisms: The interaction between traditional monetary policy and the crypto market has surpassed simple liquidity transmission, necessitating the inclusion of 'narrative game' and 'technical supply-demand' dimensions.
6.2 Policy Recommendations
Investor Strategies: Employing 'volatility hedging' and 'cross-cycle allocation' to avoid singular bets on policy shifts.
Regulatory Perspective: Strengthen on-chain data monitoring to prevent liquidity black holes and DeFi chain risks.
Fed Policy Design: Need for more precise communication of the synergistic effects of QT and interest rate policies to avoid market expectation confusion.

Innovative Explanation
This paper groundbreakingly incorporates the Fed's policy mix, market expectation psychology, and technical factors of the crypto ecosystem into a unified framework, revealing the nonlinear relationship between slowing QT and Bitcoin's downside space. By introducing concepts such as 'expectation overshoot' and 'endogenous fragility', it provides a new theoretical tool to understand the dynamic game between cryptocurrencies and traditional monetary policies, filling the limitations of the existing research on 'one-way transmission of policy'.
