Bitcoin, Liquidity and the Return of the Macro Trade

The return of the macro constraint

The immediate pressure on Bitcoin has emerged from an unusual combination of geopolitical disruption and monetary uncertainty.

The Iran conflict continues to influence global energy markets, with renewed threats to shipping around the Strait of Hormuz sustaining concerns about oil supply. Brent crude was trading above $100 a barrel in early Asian trading on 8 October, while the US 10-year Treasury yield remained around 5.3%, having reached a 24-year high during the previous session. The dollar index was close to 102.2, supported by elevated US yields and renewed concerns about European sovereign debt.

The transmission from these developments into Bitcoin is indirect but economically important. Higher energy prices can increase inflation expectations, making central banks less willing to reduce interest rates and potentially requiring additional monetary restraint. Higher bond yields then increase the return available on conventional financial assets, while also raising the discount rates applied to investments whose value depends heavily on future demand.

Bitcoin does not generate interest, dividends or contractual cash flows. Its valuation therefore cannot be assessed through the same earnings framework used for equities or the yield calculations used for bonds. Nevertheless, the opportunity cost of holding Bitcoin changes when investors can obtain substantially higher returns from government securities, particularly when those returns are available without taking comparable market-price risk.

The stronger dollar adds another layer of pressure. Because Bitcoin is predominantly quoted and traded against the dollar, changes in the currency influence its purchasing power for international investors. More importantly, a rising dollar often accompanies tighter global financial conditions, particularly when the increase reflects stronger US yields or heightened demand for dollar liquidity.

These relationships are not mechanical. Bitcoin can rise during periods of dollar strength, and its sensitivity to Treasury yields varies considerably across market regimes. What matters is the combination of forces currently operating: expensive energy, elevated borrowing costs, a firm dollar and uncertainty about the willingness of investors to commit additional capital to volatile assets.

The result is an environment in which favourable developments specific to Bitcoin may struggle to overcome broader macroeconomic restraint.

The Federal Reserve is not providing the relief markets expected

Wednesday's publication of the Federal Reserve's September meeting minutes provides a useful explanation for that tension.

The Federal Open Market Committee raised its target interest-rate range by 25 basis points to 3.75–4.00% in September, the first increase of 2026. The minutes confirmed that most participants expected another increase to be appropriate before the end of the year, although policymakers emphasised that subsequent decisions would depend on incoming economic information. Some viewed higher rates primarily as insurance against persistent inflation, while others considered additional tightening necessary given the underlying strength of economic demand.

The distinction is significant. A central bank raising rates to prevent temporary energy pressures from spreading into broader inflation may be more willing to pause as those pressures subside. A central bank concerned that economic activity itself is generating excessive demand faces a more persistent problem.

The minutes suggest that both concerns are present.

Policymakers discussed inflationary pressures arising from energy disruption and the expansion of AI-related investment, while several participants considered the prevailing policy rate insufficiently restrictive. At the same time, they acknowledged that higher Treasury yields and changing financial conditions could influence the amount of additional tightening required.

Markets have responded by shifting the expected timing of another increase rather than abandoning the possibility altogether. Early on 8 October, futures pricing implied approximately a 19% probability of a rate increase at the 27–28 October meeting, compared with around an 80% probability of an increase by December.

For Bitcoin, that is a less supportive development than a simple reduction in October rate expectations might suggest.

A pause is not equivalent to monetary easing. If the Federal Reserve holds its policy rate steady while inflation expectations, longer-term yields and the dollar remain elevated, financial conditions can continue to restrict investment appetite.

There is also a difference between the Fed deciding that further tightening is unnecessary and the economy entering a period in which liquidity becomes progressively more abundant. The former may remove an immediate source of uncertainty. The latter would represent a more substantial change in the conditions under which investors allocate capital.

Bitcoin's recent weakness suggests that markets are paying greater attention to that distinction.

Liquidity is more complicated than the Fed's balance sheet

The relationship between Bitcoin and liquidity is frequently discussed as though a single measure of money supply or central-bank assets could explain the direction of cryptocurrency prices.

That interpretation is too simplistic.

Liquidity operates through several related but distinct mechanisms. Banking-system reserves determine part of the capacity of financial institutions to settle transactions and intermediate funding. Money-market conditions influence the cost and availability of short-term finance. Bond yields affect the relative attractiveness of different assets, while credit spreads and market volatility influence the willingness of investors to take risk.

There is also the question of how much capital is actually available to purchase Bitcoin, whether through exchange-traded products, institutional portfolios, cryptocurrency exchanges or leveraged trading accounts.

These measures can move in different directions.

The Federal Reserve's September minutes reported that reserve balances remained within a range considered ample, while short-term funding markets were functioning normally. The Fed had paused reserve-management purchases because existing conditions did not require additional operations, although it retained the ability to purchase Treasury bills when necessary to maintain adequate reserves.

That is an important distinction from the liquidity environment investors experienced during earlier periods of large-scale quantitative easing.

Reserve-management purchases are intended to maintain the effective functioning of the monetary system. They should not automatically be interpreted as an attempt to stimulate asset prices through sustained monetary expansion.

Equally, an ample level of banking reserves does not guarantee that investors will increase their exposure to Bitcoin. Capital can remain within money-market funds, government securities or other relatively defensive investments when the compensation for taking additional risk appears unattractive.

The Bank for International Settlements has examined how monetary-policy transmission depends on market liquidity and the ability of financial intermediaries to absorb risk. Its research highlights the importance of arbitrage capacity and Treasury-market conditions in determining how changes in policy affect longer-term yields. Although that research does not establish a direct relationship with Bitcoin, it reinforces the broader point that liquidity cannot be reduced to the size of a central-bank balance sheet.

For Bitcoin investors, the practical implication is that a change in monetary policy may not produce the expected market response unless it is accompanied by an improvement in the wider financing environment.

A pause in interest-rate increases can coexist with expensive capital, limited risk appetite and continued pressure on speculative assets.

Institutional adoption has changed the transmission mechanism

The introduction of US spot Bitcoin exchange-traded products in January 2024 created a more direct connection between cryptocurrency markets and conventional investment portfolios.

These products allow investors to obtain exposure through established securities-market infrastructure without managing private keys or holding Bitcoin directly. The Securities and Exchange Commission approved their listing and trading while explicitly distinguishing that decision from an endorsement of Bitcoin itself.

The significance extends beyond convenience.

Bitcoin can now compete more directly for capital within portfolios containing equities, bonds, commodities and other alternative assets. Institutional investors can increase or reduce their exposure using familiar investment vehicles, making Bitcoin more accessible but also potentially more sensitive to conventional portfolio rebalancing and risk-management decisions.

Recent fund-flow data illustrate both the scale of participation and its variability.

According to Farside Investors, US spot Bitcoin ETFs recorded approximately $999 million of net inflows on 21 September and another $715 million on 22 September. Demand subsequently moderated, with the funds experiencing approximately $149 million of net outflows on 30 September. The first two trading sessions of October brought renewed inflows of $102.7 million and $189.9 million respectively, followed by an $89.8 million withdrawal on 5 October and a return to $118.8 million of inflows on 6 October.

These movements suggest that institutional participation remains substantial, but the direction of marginal demand is far from consistent.

The flow data for 7 October were still incomplete when this article was prepared, so they should not yet be treated as a final measure of the day's institutional demand.

It is also important not to overstate what ETF flows reveal. Net creations and redemptions are useful indicators of investment demand, but they do not capture every transaction in the underlying Bitcoin market, nor do they establish that a particular day's price movement was caused by fund activity.

Nevertheless, the broader relationship matters. A market that increasingly relies on capital allocated through conventional investment structures is likely to become more exposed to the same financial conditions influencing those allocations.

When government bonds offer higher yields, portfolio volatility increases or investors reduce exposure to risk assets, Bitcoin must compete for capital in that environment.

Institutional adoption therefore provides a potentially deeper and more durable source of demand while also increasing the importance of macroeconomic conditions.

Bitcoin's relationship with risk assets is no longer incidental

The growing connection between cryptocurrency markets and conventional finance is supported by research extending well beyond the current cycle.

An International Monetary Fund working paper published in 2023 examined the relationship between cryptocurrency prices, global equities and US monetary policy. The researchers identified a common factor explaining much of the variation across cryptocurrency prices and found that tighter US monetary policy reduced that factor through the risk-taking channel. The study also associated increasing cryptocurrency-equity correlations with greater institutional participation.

A separate IMF analysis found that Bitcoin's correlation with major equity markets increased substantially during the pandemic period, alongside stronger transmission of volatility between cryptocurrency and traditional financial markets. The researchers cautioned that these relationships could increase financial-stability risks during periods of market stress.

These findings should not be interpreted as proof that Bitcoin will always behave like a technology stock. Correlations change over time, and the structure of cryptocurrency markets has evolved considerably since those studies were conducted.

They do, however, challenge the assumption that Bitcoin's monetary characteristics automatically make it independent of conventional financial conditions.

Bitcoin's supply is governed by its protocol, but its demand is determined by investors operating within a broader financial system. Those investors face changing borrowing costs, portfolio constraints, liquidity requirements and expectations about future returns.

The distinction between supply and demand is particularly important when evaluating Bitcoin's relationship with inflation.

A predetermined supply schedule may support an argument about long-term scarcity, but it does not guarantee protection against a sudden inflation shock. If that shock causes central banks to maintain restrictive policy and investors to reduce exposure to volatile assets, Bitcoin can decline even while the purchasing power of conventional currencies is under pressure.

This is not necessarily a contradiction in Bitcoin's design. It is a reflection of how market prices are established.

The digital-gold comparison is becoming more demanding

Bitcoin's fixed maximum supply has encouraged comparisons with gold, particularly among investors concerned about currency debasement, fiscal deficits and the long-term purchasing power of money.

There is an intellectual basis for that comparison. Neither asset depends on the earnings of a company, and both can attract demand from investors seeking alternatives to conventional monetary instruments.

But their market structures remain materially different.

Gold has an established role within central-bank reserves, jewellery markets and institutional investment portfolios. Bitcoin's investment market is younger, more volatile and more closely connected to leveraged cryptocurrency trading.

The current environment illustrates why those differences matter, although it also demonstrates that gold itself is not immune to financial conditions.

Gold weakened to a two-month low on 7 October as the dollar strengthened and Treasury yields remained elevated. Bitcoin experienced a sharper decline, reflecting the greater volatility and risk sensitivity commonly associated with cryptocurrency markets.

The shared direction is significant because it suggests that the immediate market response was influenced by the rising opportunity cost of holding non-yielding assets rather than a simple distinction between conventional money and alternatives to it.

Over longer periods, fiscal concerns and monetary uncertainty may support demand for scarce assets. In the short term, however, those same concerns can raise bond yields and tighten financial conditions.

An investor expecting Bitcoin to benefit from fears about currency debasement must therefore consider the possibility that the market initially responds by demanding higher yields on government debt and reducing exposure to risk.

The long-term monetary argument and the short-term liquidity argument can point in opposite directions.

That tension is central to understanding Bitcoin's current behaviour.

The bond market is becoming the more important signal

One of the more revealing developments this week has occurred outside cryptocurrency markets altogether.

US Treasury yields rose sharply on 7 October, with the benchmark 10-year yield reaching approximately 5.36% before retreating following a well-received $39 billion auction. Demand at the auction was stronger than expected, with a bid-to-cover ratio of 2.77 and a relatively small allocation to primary dealers.

The auction provided evidence that investors were willing to absorb government debt at prevailing yields, reducing immediate concerns about market demand. It did not, however, remove the broader pressures that had driven yields higher.

Those pressures include persistent inflation uncertainty, substantial government borrowing requirements and growing competition for investment capital.

The latter is becoming particularly relevant as major technology companies increase borrowing to finance AI infrastructure. Reports of large prospective debt issuance by companies including Broadcom and SpaceX have added to concerns that private-sector demand for long-term capital may compete with sovereign borrowers.

For Bitcoin, the implications are indirect but potentially substantial.

A market in which governments and large corporations must offer increasingly attractive yields to secure financing creates a different environment for assets that do not generate cash flows. Investors have more opportunities to obtain returns through conventional instruments, while the cost of financing leveraged positions can remain elevated.

There is also a broader portfolio effect. Rising bond yields can put pressure on equity valuations and increase volatility across financial markets, prompting investors to reconsider allocations to their most volatile holdings.

Bitcoin may therefore respond more strongly to developments in the Treasury market than to changes in the Federal Reserve's next-meeting probabilities.

That does not mean the two are independent. Treasury yields incorporate expectations about future policy, inflation, economic growth and compensation for holding long-duration debt. The important point is that the resulting financial conditions may differ substantially from what a narrow reading of the expected policy rate would suggest.

What would improve the environment for Bitcoin?

The constructive case for Bitcoin does not require an immediate return to the extraordinary monetary conditions seen during earlier stimulus periods.

A more gradual improvement in financial conditions could be sufficient to support renewed demand, particularly if institutional participation remains substantial.

One possible path would involve moderation in energy prices, declining inflation expectations and greater confidence that the Federal Reserve has completed its tightening cycle. If Treasury yields subsequently fall and the dollar weakens, the opportunity cost of holding Bitcoin would decline, potentially making the asset more attractive within diversified portfolios.

Sustained positive ETF flows would strengthen that interpretation by demonstrating that the improvement in financial conditions was translating into actual investment demand.

There is a plausible basis for considering this outcome. September's US employment report showed sharply weaker payroll growth, and several Federal Reserve officials have recently emphasised the value of patience. If subsequent inflation data also moderate, the central bank may conclude that additional tightening is unnecessary.

But the alternative remains credible.

Renewed disruption to Middle Eastern energy supplies could sustain inflation pressure, while fiscal concerns and substantial debt issuance keep longer-term Treasury yields elevated. Under those conditions, even a Federal Reserve pause might provide relatively little relief to Bitcoin.

A stronger dollar and weaker institutional inflows would reinforce the restrictive environment, particularly if broader equity markets also begin to respond negatively to higher borrowing costs.

There is a third possibility that deserves consideration: a more severe deterioration in financial-market functioning.

A sudden liquidity shock could initially force investors to sell Bitcoin alongside other liquid assets to meet funding requirements or reduce leverage. Central-bank intervention might subsequently stabilise markets, but it would be dangerous to assume that Bitcoin would benefit immediately from such a development.

The sequence matters. Liquidity crises often create forced selling before policy responses begin to influence risk appetite.

For that reason, a financial-market disruption should not automatically be treated as a favourable catalyst for Bitcoin merely because it could eventually prompt monetary support.

What investors should watch next

The most useful indicators for Bitcoin over the coming weeks are unlikely to be confined to cryptocurrency markets.

The first is the direction and composition of US Treasury yields. Falling yields driven by improving inflation expectations would have different implications from falling yields caused by a sudden deterioration in economic growth or financial stability. Equally, a rise in nominal yields accompanied by higher real yields would represent a more direct increase in the opportunity cost of holding non-yielding assets.

The second is the dollar. A sustained reversal in recent dollar strength could indicate that financial conditions are becoming less restrictive internationally, particularly if accompanied by improving risk appetite.

The third is the behaviour of institutional Bitcoin flows. Individual ETF sessions can be volatile and should not be overinterpreted, but a sustained sequence of inflows or outflows would provide useful evidence about the willingness of conventional investors to increase exposure.

The fourth is the Federal Reserve's assessment of inflation and financial conditions. The September minutes indicate that policymakers remain concerned about persistent inflation, but the next decision will depend on data that were unavailable when the Committee last met. The 27–28 October meeting will therefore be important not simply for the rate decision itself, but for what the accompanying communication reveals about the expected duration of restrictive policy.

Finally, developments in energy markets remain central to the outlook. A durable reduction in geopolitical disruption could relieve inflation pressure and improve the monetary environment. Renewed escalation could have the opposite effect, particularly if it pushes energy prices higher while weakening global growth.

None of these indicators provides a reliable short-term price forecast on its own. Their value lies in showing whether the conditions supporting investment demand are improving or deteriorating.

Bitcoin is becoming a more conventional macro asset

There is an apparent paradox at the centre of Bitcoin's development.

The asset was designed to operate independently of central banks and conventional financial intermediaries. Yet as it becomes more widely held through institutional investment products, its market price is increasingly influenced by the decisions of those same institutions and by the financial conditions shaped by monetary policy.

That does not make Bitcoin equivalent to an equity, bond or commodity. Its supply characteristics remain distinctive, and the long-term reasons investors hold it may differ considerably from the motivations governing short-term trading.

It does mean that the relationship between Bitcoin and the broader financial system has become more important.

The latest market movements offer a useful illustration. Expectations of an immediate Federal Reserve rate increase have diminished, but Bitcoin has weakened as Treasury yields remain elevated, the dollar strengthens and investors confront renewed geopolitical uncertainty. Institutional fund flows have shown that demand can recover quickly, but also that it is sensitive to changing market conditions.

The evidence therefore points towards a more complicated investment framework than either an automatic inflation hedge or a simple proxy for global money supply.

Bitcoin's long-term value proposition may continue to rest on scarcity, decentralisation and increasing adoption. Its shorter-term performance, however, is increasingly determined by the price and availability of capital.

That distinction is likely to become more important as institutional participation expands.

The central question for investors is no longer simply whether Bitcoin can attract more capital over time. It is whether the wider financial environment will allow that capital to be deployed on terms that make taking additional risk attractive.

For now, the bond market, the dollar and the Federal Reserve are providing a less comfortable answer than the recent improvement in Bitcoin's institutional adoption might suggest.

Bitcoin has not ceased to be a monetary experiment. But it has become a more established participant in global financial markets, and those markets are once again being shaped by the cost of money.

That is why the macro trade has returned.
