Speculative excess can emerge from individually rational decisions when incentives across the financial system favor continued capital deployment.
Independent judgment gets harder as the cycle matures, with careers, compensation, and consensus reinforcing the prevailing narrative.
The challenge is to look beyond consensus and ask whether allocations still reflect objective measures of risk and return.
Why do extreme speculative episodes continue to repeat despite centuries of well-documented evidence of their devastating consequences? This question has perplexed financial professionals for centuries. The recently published paper “Speculative Supply Chains: How Rational Incentives Manufacture the Madness of Crowds” explains what I have come to believe constitutes part of the answer.
It introduces the concept of a speculative supply chain, which is a network of financial intermediaries whose incentives gradually align toward the continuous deployment of capital. As these structures mature, incentives favoring capital deployment grow stronger and become more closely aligned across various participant groups. At the same time, risk awareness becomes increasingly segmented, and corrective feedback is gradually suppressed. This, in turn, prevents most market participants from recognizing the widening gap between prevailing market narratives and long-standing economic principles. This process helps explain how behavior that appears entirely rational in isolation can aggregate into speculative excesses that are irrational at the system level.
This article is organized as a series of frequently asked questions addressing the framework, the evidence behind it, and its implications for today’s financial markets.

Q1: What is a speculative supply chain?
A speculative supply chain is defined as a network of financial intermediaries whose incentives become increasingly aligned toward the continuous deployment of capital. Such supply chains are populated by a variety of actors responsible for capital allocation decisions, but those decisions are not based solely on the merits of the investments. Instead, they are influenced by participants’ own interests, including job security, professional advancement, asset growth, fee generation, and the perceived safety of crowds. Figure 1 shows a high-level illustration of the speculative supply chain driving capital deployment in private equity and private credit.
Because the incentives within speculative supply chains generally reward capital deployment, they tend to intensify as speculative episodes gain momentum and attract additional participants. As this occurs, incentives become increasingly aligned across participant groups. Consequently, capital allocation decisions become progressively less dependent on independent assessments of risk and return and more dependent on collective participant self-interest. Speculative episodes reach dangerous levels when incentives favoring capital deployment become substantially more influential than objective evaluations of the corresponding investment opportunities.

Q2: What evidence led to this discovery?
I first introduced the speculative supply chain concept in two chapters of Investing in U.S. Financial History. I used it to explain the Dot-com bubble at the turn of the 21st century and the Global Financial Crisis of 2008–2009. At the time, however, I viewed it primarily as a useful way of understanding those two episodes rather than as a broader explanatory framework.
After the book was published, I recognized the same pattern emerging in private markets and alternative asset classes more broadly. The similarities were too striking to ignore. That realization led me to revisit other historical speculative episodes, where I found the same underlying structure repeatedly emerging despite differences in the assets, institutions, and time periods.
The recurring pattern suggested that the speculative supply chain was not unique to a handful of events but may instead constitute a fundamental mechanism that helps explain why many speculative episodes repeatedly arise throughout financial history.
Q3: How do speculative supply chains evolve?
The formation and maturation of a speculative supply chain typically occurs gradually over many years—and in some cases decades. While the speculative episode that ensues may appear unique on the surface, a common progression is often observed as depicted in the following analysis in seven parts.
The Seven Phases of a Speculative Supply Chain
- Disruptive Economic Event
Speculative supply chains often emerge following a disruptive economic event that creates a temporary market dislocation. Examples may include financial shocks, natural disasters, major wars, or the introduction of a ground-breaking technological advancement. During this period, capital is scarce relative to attractive opportunities, allowing capital providers who are both early and skilled to generate outsized returns. Once these returns become broadly visible, they attract imitators who seek to replicate the results by adopting a strategy that they believe explains the initial success.
- Risk Segmentation
As capital inflows accumulate, financial activity becomes increasingly specialized and organized in an assembly line–like structure. Each participant becomes responsible for a discrete stage of the capital deployment process and evaluates risk primarily from a local point of view. Although incremental risks may be understood from this limited vantage point, few participants comprehend how those risks are amplified elsewhere in the supply chain and compound collectively. Whereas aligned incentives drive the creation of risk in speculative supply chains, risk segmentation is the structural feature that obscures it.
- Growth-Oriented Incentive Alignment
As participation expands, incentives across the supply chain become increasingly aligned toward continued capital deployment because the economic success of most participants becomes more dependent upon the system's growth. In the most dangerous supply chains, virtually no major participant has a strong economic incentive to slow the deployment of capital. Fee structures, compensation systems, market-share objectives, media attention, peer pressure, and political pressures all reinforce expansion rather than restraint.
- Corrective Feedback Suppression
As incentive alignment strengthens and is reinforced by favorable short-term outcomes, traditional corrective mechanisms weaken. Participants who might otherwise act to constrain capital deployment face progressively steeper costs for challenging the prevailing narrative. Allocators face career risk; investment consultants and wealth advisors risk losing clients; and members of the media risk reduced audience engagement. As a result, warning signs are discounted, rationalized, ignored, or actively suppressed.
- Narrative Detachment from Long-Standing Economic Principles
As excess capital accumulates, the narrative supporting continued expansion eventually detaches from fundamental economic principles. Supply chain participants continue deploying capital, nonetheless. They often rationalize what would otherwise be considered clear violations of time-tested economic principles. They may embrace new, unproven metrics. Phrases such as “stocks have reached a permanently high plateau,” “profits no longer matter,” or “real estate has never declined on a national level” help justify narratives that have become detached from historical precedent.
- Correction and Misattribution
The speculative episode ends when a narrative can no longer support the weight of conflicting evidence and/or structural constraints that create a hard limit on further capital deployment. The severity of the correction depends on multiple factors, such as the extent of excess capital investment, degree of leverage used, and relative exposure of the traditional banking system. The most severe events cascade into major financial crises, while less severe events may limit losses primarily to investors with direct exposure.
- Postmortem Analysis and Repetition
Postmortem analyses routinely focus on the actions of various supply chain participants that appear to have contributed disproportionately to the excess. For example, after the Dot-com collapse in 2001, attention focused on Wall Street securities analysts. After the GFC ended in early 2009, attention centered on large investment banks. In both cases, the postmortems overlooked the common underlying mechanism—the existence of a mature speculative supply chain. Consequently, reforms often target the most visible participants in the previous crisis while the conditions necessary for the next speculative supply chain quietly emerge elsewhere.
A great paradox of speculative supply chains is that their most defining characteristics become progressively more difficult to recognize as speculative episodes advance. By the time risks have peaked, many of the individuals best positioned to recognize them are no longer able to resist the incentives to ignore them. Their compensation, professional relationships, reputations, and future opportunities have become too dependent on continued capital deployment.
The irresistible pull of these incentives helps explain why speculative episodes often persist well beyond the point at which underlying risks seem obvious in retrospect. It also explains why outsiders, whose economic interests are less dependent on the perpetuation of the status quo, are more likely to recognize the warnings and voice their concerns.
Q4: How can finance professionals use this framework?
The framework is unusually valuable across a wide variety of investment professional stakeholders. A few of the more important beneficiaries include.
Trustees of Institutional Plans — In many institutional investment programs, trustees are the final line of defense. The paper argues the private equity and private credit allocations are the output of a mature speculative supply chain. Despite more than two decades of massive investment in private markets, investment staff, consultants, private market managers, conference organizers, trade media, and even academic departments have strong incentives to continue deploying capital. Trustees should understand how these incentives may shape the recommendations that ultimately reach the boardroom and consider whether proposed allocations are being driven by investment merit or by the incentives embedded within the supply chain.
Investment Consultants — Many investment consultants have a fiduciary duty to recommend asset allocations and investment managers that are in the best interests of plan beneficiaries. If the expected benefits of an investment become increasingly uncertain while the incentives to continue deploying capital remain strong, consultants must ask themselves whether their recommendations continue to satisfy their fiduciary obligations.
Wealth Managers — Many wealth managers also have a fiduciary duty to recommend investments that are in the best interests of their clients. Understanding how speculative supply chains evolve may help them recognize when an investment has reached the stage where distribution is being prioritized over investment quality, potentially leaving individual investors to absorb risks that earlier participants have already recognized.
Policymakers and Regulators — One reason speculative episodes tend to recur is that policymakers often focus on preventing the last crisis rather than identifying the conditions that give rise to the next one. New regulations frequently address the most visible vulnerabilities of the previous episode, while a new speculative supply chain develops elsewhere. Private credit illustrates this dynamic. By focusing on the formation and maturation of speculative supply chains, rather than solely on the characteristics of the last crisis, policymakers may be better positioned to identify emerging systemic risks before they become widespread.
Academia — Academic finance has devoted tremendous effort to developing increasingly sophisticated methods for evaluating investment performance, risk, and manager skill. Yet comparatively little attention is paid to whether the data feeding these models may itself be systematically influenced by the incentives of the institutions producing it. The speculative supply chain offers a complementary lens through which to analyze financial markets—one that shifts the focus from evaluating investment outcomes to understanding the incentives of the intermediaries responsible for creating, distributing, and valuing investment products. By examining how individually rational incentives shape the information that ultimately reaches investors, researchers may gain a deeper understanding of why speculative episodes continue to emerge despite increasingly sophisticated analytical tools.
Q5: Why hasn’t anybody written about this before?
In truth, several scholars have identified important components of the speculative supply chain framework. Hyman Minsky emphasized the tendency for financial stability to foster increasingly fragile financial structures, while Eugene Fama, agency theorists, and researchers in behavioral finance have each illuminated different aspects of market behavior, incentives, and decision-making. This paper builds on those insights while arguing that they have largely been developed in isolation. Its principal contribution is not the introduction of entirely new concepts, but rather their integration into a unified framework.
Yet the lack of synthesis is only part of the explanation. Speculative supply chains are inherently difficult to recognize because the forces that create them also tend to conceal them. Several characteristics make these systems unusually resistant to detection.
Unspoken Decision Drivers — Individual incentives often exert a powerful influence on investment decisions, yet they are rarely discussed explicitly before, during, or after a speculative episode. Participants typically justify their decisions by pointing to investment characteristics, prevailing narratives, or accepted analytical frameworks, while the personal incentives shaping those decisions remain largely invisible.
Biased Metrics — As speculative supply chains mature, the metrics used to evaluate investment quality increasingly become products of the capital flows they are intended to evaluate. Rising valuations, favorable historical returns, and strong performance statistics may therefore reflect the effects of sustained capital inflows rather than genuine improvements in underlying investment opportunities.
Narrative Reinforcement — The narratives supporting continued capital deployment are frequently created, disseminated, and reinforced by participants whose economic interests depend upon the expansion of the supply chain. As those narratives gain widespread acceptance, they become increasingly difficult to distinguish from objective analysis.
Suppression of Dissent — Mature speculative supply chains leave progressively fewer participants with both the incentive and the credibility to challenge the prevailing consensus. Those who raise concerns tend to face increasingly severe professional, financial, or reputational costs as supply chains mature, while those who remain supportive are rewarded. As a result, corrective feedback becomes scarcer precisely when it is most needed.
Collectively, these characteristics make speculative supply chains inherently self-concealing. The same incentive structure that fuels their growth also obscures their existence, making them most difficult to recognize precisely when they pose the greatest systemic risk.
Q6: What evidence suggests that a speculative supply chain is driving allocations to private markets?
The second case study in the paper focuses on private equity and private credit in the present day. But it is a test case. We do not yet know how this will end. Nevertheless, private credit and private equity markets already show clear signs that align with five phases of the speculative supply chain framework.
Disruptive Economic Events — Both private equity and private credit allocations accelerated after disruptive economic events. Private equity allocations accelerated after the extraordinary success of the Yale Endowment model, while private credit emerged from the temporary lending vacuum created after the Global Financial Crisis. In both cases, early participants generated exceptional returns under conditions that were difficult to replicate at scale, attracting waves of imitators.
Risk Segmentation — Capital deployment has become highly specialized. Fund managers, consultants, Outsourced CIOs (OCIOs), investment staff, trustees, wealth managers, and distribution platforms each evaluate only a portion of the investment process. Few participants assess how risks accumulate across the system as a whole.
Growth-Oriented Incentive Alignment — The economic interests of nearly every major participant increasingly benefit from continued capital deployment. Asset growth, fee revenue, compensation, professional advancement, market share, and product expansion all reinforce larger allocations rather than greater restraint.
Corrective Feedback Suppression — As allocations have expanded, skepticism has become increasingly costly. Trade media, conferences, professional organizations, academics, and many market participants have stronger incentives to reinforce prevailing narratives rather than to challenge them, reducing the influence of dissenting voices.
Narrative Detachment from Long-Standing Economic Principles — Despite record capital inflows, slowing exits, declining expected illiquidity premiums, and the rapid expansion of continuation vehicles and evergreen funds, narratives supporting continued allocations remain remarkably optimistic. These developments appear increasingly difficult to reconcile with long-standing principles of supply, demand, and expected returns.
Whether the current cycle ultimately produces a severe correction remains uncertain. The private markets case is, after all, a test. If a correction occurs, history suggests attention will again focus on the most visible participants rather than the underlying supply chain. Then, future reforms will likely target the institutions most closely associated with the eventual downturn. Unless the underlying speculative supply chain is recognized, incentives will migrate, and a new speculative supply chain will begin forming elsewhere in the financial system.
Recognizing the Next Speculative Supply Chain
A perennial debate in finance is whether speculative episodes can be identified and potentially mitigated before the most damaging consequences arrive. Thus far, neither academics nor practitioners have created a workable framework.
This paper argues that extreme speculative episodes are often not the result of widespread irrationality. Rather, they emerge when speculative supply chains create aligned incentives toward continuous capital deployment, while operating with highly segmented risk awareness across specialized participants.
The implications for investors, regulators, and policymakers are significant. Efforts to prevent future crises often focus on correcting the most visible vulnerabilities that contributed to the most recent speculative event. Yet financial history suggests that speculative supply chains tend to migrate to a new area of the market. Failure to identify and address the supply chain migration allows risk to reappear elsewhere, evolve through new intermediaries, and develop novel structures capable of attracting new sources of capital.
This framework suggests that the most effective means of identifying dangerous speculative conditions may be to focus less on the vulnerabilities of the previous crisis and more on the emergence and migration of speculative supply chains. By monitoring the formation of risk-segmented capital deployment systems and the incentives that increasingly favor their expansion, society may improve its ability to recognize dangerous speculative conditions and intervene before the most damaging consequences become unavoidable.
