The Looming Market Crash: Tech Bubble, Geopolitical Shocks, and the Fed’s June Dilemma
By Damir Tokic, Professor of Finance and Seeking Alpha Analyst
The S&P 500, propelled by an exuberant tech sector, is rapidly approaching historical valuation extremes, signaling the formation of a colossal bubble. Simultaneously, an escalating Iran war threatens to unleash a devastating inflation shock, driving oil prices skyward and bond yields higher. This escalating geopolitical tension significantly amplifies the probability of a grim market outlook. While the Federal Reserve officially maintains a dovish stance, market participants are already pricing in interest rate hikes. This divergence suggests that a hawkish pivot by the Fed in June could be the decisive spark that finally pricks this burgeoning bubble.

Is the Tech Rally a Mirage?
A closer look at the S&P 500’s (SPY) performance over the past three months, since the onset of the Iran war, reveals a stark disparity:
- The S&P 500 has climbed 10% since February 27th.
- Technology stocks (XLK) have surged by over 37%.
- The second-highest performer, Consumer Discretionary (XLY), gained a modest 3%. However, this figure is skewed by Amazon (AMZN), which accounts for 27% of XLY and rose 28%, and Tesla (TSLA), making up 20% of XLY with an 8% gain. Both are fundamentally technology companies and integral members of the “Magnificent Seven.”
This leads to a critical question: Did the perceived ceasefire in the Iran war disproportionately benefit only the tech sector, particularly semiconductors (SMH)?
From my perspective, the answer is unequivocally no. The market’s initial, almost blind, assumption that the war was over — and, more importantly, that we would miraculously evade an inflation shock and the ensuing demand-destroying recession — served as a green light for rampant speculation, reinflating the bubble.
However, this current bubble differs significantly from the dot-com era of 2000. That earlier bubble was purely driven by speculative expectations and an uncontrolled expansion of price-to-earnings (P/E) multiples. The 2026 bubble, by contrast, is far more insidious. It’s built on “backward-looking” vested profits and a naive expectation that these profits will continue indefinitely. Specifically, the staggering $770 billion in AI capital expenditure by hyperscale enterprises is concentrated among core beneficiaries, primarily semiconductor companies like Micron Technology (MU).
Yet, the Shiller P/E (Cyclically Adjusted P/E Ratio) for both 2000 and 2026 hovers above 40x, indicating a comparable level of market exuberance and overvaluation.
The profitability of these tech giants, however, is unsustainable. The growth in AI capital expenditure is likely to decelerate and eventually decline. When might this inflection point occur?
In my assessment, this $770 billion AI capital expenditure can be traced back to a meeting between President Trump and tech executives early in his second term. During this meeting, Trump, seated next to Mark Zuckerberg, inquired about Meta’s planned AI capex, to which Zuckerberg responded, “Sorry, I’m not ready yet… I’m not sure what number you want.”
I believe this $770 billion AI capital expenditure is, in essence, a “Trump stimulus” imposed upon private enterprise, and it is fundamentally unsustainable. Should the Democratic Party secure victory in the upcoming midterm elections, this trend is highly likely to reverse.
Therefore, the market’s euphoric reaction to the Iran war ceasefire is merely an extension of this “Trump stimulus,” and quite possibly a final, frenzied surge. The pressing questions now are: Where is the peak of this rally, and what will ultimately trigger the inevitable crash?

Iran War Escalation and the Impending Inflation Shock
Let us now turn our attention back to the Iran war. This is a critically important variable, as it possesses the potential to ignite a classic systemic shock that could irrevocably burst the bubble.
A typical bubble collapse generally unfolds in three stages: 1) escalating inflation, 2) Federal Reserve interest rate hikes, and 3) a recession leading to a bear market.
First, let’s examine inflation. Inflation can be either demand-driven or supply-driven.
Demand-driven inflation is initially favorable for markets, as companies possess pricing power, often accompanied by an “overheating” economy where early revenue and profit growth are realized. The Fed then intervenes with rate hikes to suppress demand, which ultimately leads to higher unemployment and a recession.
In contrast, supply-driven inflation is profoundly negative for markets from the outset, as companies lose their pricing power — a scenario typically observed in weak economic or stagflationary environments. The Fed is then compelled to raise interest rates amidst an already struggling economy, which inevitably precipitates a deeper recession.
The Iran war is currently triggering a destructive form of supply-side inflation. It has created a global energy shortage due to the closure of the Strait of Hormuz, in addition to a food shortage stemming from fertilizer scarcity and deficits in numerous other derivative products and chemicals.
Fundamentally, Iran has maintained its closure of the Strait of Hormuz for three months. Throughout this period, the global economy has been drawing down strategic petroleum reserves to compensate for the lost oil supply. These reserves are projected to reach critical operational levels in June.
If Iran does not immediately reopen the Strait of Hormuz, the global economy faces the most severe energy shock in history. Due to a genuine physical shortage, crude oil prices could soar to over $200 per barrel until demand is utterly decimated, causing prices to recede. The destruction of demand, in turn, directly correlates with a recession.
It is precisely for this reason that President Trump is acutely aware of the gravity of the situation. For the past two months, he has been attempting to negotiate with Iran to reopen the Strait of Hormuz, but all efforts have proven unsuccessful.
As it stands, reaching an agreement with Iran appears almost impossible for three key reasons:
- Firstly, Iran insists on retaining control over the Strait of Hormuz even after its reopening, which constitutes a red line for the United States.
- Secondly, Iran refuses to negotiate on nuclear issues and is highly unlikely to agree to any nuclear deal, representing another red line for the U.S.
- Thirdly, even if Trump were to compromise on Iran’s conditions to reopen the Strait and reach some form of agreement, Israel would intervene to prevent it, viewing a nuclear-armed Iran as an existential threat.
So, what is the true state of affairs now?
My previous assessment was that Trump’s chances of striking a last-minute deal with Iran to avert an inflation shock were increasing. However, Israel would vehemently oppose such an agreement. Part of any Iran deal would necessitate a ceasefire on all fronts, including Lebanon. Israel could easily veto this agreement by directly attacking Lebanon. For Israel, this is also an existential matter, given the very real threat posed by its “neighbor,” Hezbollah.
Currently, we are facing a potentially significant escalation.
Reports indicate that Iran has now canceled all contact with the United States, signifying a complete halt to negotiations. Moreover, Iran has fully blockaded the Strait of Hormuz and is threatening to further close the Bab el-Mandeb Strait. Should this occur, over 30% of global energy supply would effectively vanish — an outcome nothing short of a true disaster.
Despite President Trump’s claims of ongoing dialogue with Israel and Hezbollah, and even assertions that negotiations with Iran are continuing, these statements alone have been sufficient to push the tech sector to new record highs. However, as of now, these claims remain unconfirmed by any official sources.
The June Reckoning
Consequently, the probability of a market crash erupting in June is rapidly escalating. Global oil inventories are set to reach critical levels in June. Once they fall below this threshold, crude oil (CL1:COM) prices will surge dramatically due to a genuine supply shortage, at which point mere rhetoric will be insufficient to “talk down” oil prices.
As a result, bond yields will also skyrocket, driven by rising inflation expectations and fiscal concerns pushing real interest rates higher. Furthermore, when inflation surges, verbal intervention to “dissuade” a bond market sell-off will prove utterly futile.
Crucially, the Federal Reserve must respond at its June FOMC meeting. This is highly likely to become the ultimate trigger for the bubble’s collapse. Specifically, the Fed’s official Quarterly Economic Projections (SEP) still signal that the next policy move will be a rate cut, maintaining a dovish bias.
However, the federal funds futures market has already priced in a tightening bias. Current market predictions indicate a greater than 50% chance of at least one rate hike by December 2026, with the possibility of two.
The Federal Reserve will then be compelled to align with market expectations, making an official hawkish shift at its June meeting. This action alone would be sufficient to cause the bubble to burst instantaneously. Even if the Fed defiantly maintains a dovish stance, its complete loss of market credibility would likely trigger a dramatic surge in 10-year Treasury yields, leading to an even more profound systemic shock.
Investment Outlook: Brace for Impact
The S&P 500’s cyclically adjusted P/E ratio is currently nearing new historical highs, well above 40x, signaling the formation of a super bubble. An inflation shock triggered by the Iran war could prick it at any moment, and the Federal Reserve’s official hawkish pivot in June may well be the fatal blow. Investors should prepare for a major market correction, the severity of which could be comparable to the bear markets of 2000 and 2008. Remember, all bubbles, eventually, burst.
