Iran, Stagflation, and a Frozen Fed: The Triple Threat Driving the S&P 500’s Worst Streak in a Year

The S&P 500 is closing out its third consecutive losing week — the longest such streak in nearly a year — and the forces behind the selloff are not the kind that resolve quickly. A geopolitical shock, deteriorating economic data, and a Federal Reserve with no room to maneuver have converged into a triple threat that is reshaping how investors should be positioning right now.

The index hit an all-time high of 7,002 on January 27, 2026. It has since fallen approximately 4.5%, trading near 6,684 as of Thursday’s close — its lowest level since mid-December. The Dow Jones Industrial Average is tracking for a 1.8% weekly loss, and the Nasdaq Composite has declined roughly 0.9% week-to-date. The S&P 500 is now down 1.54% on the year.

Threat #1: Iran and the Oil Shock

The U.S.-Israeli military conflict with Iran has disrupted Persian Gulf shipping lanes, sending Brent crude above $100 per barrel for the first time since August 2022 and pushing WTI crude near $96. With Iran’s new Supreme Leader signaling the Strait of Hormuz closure should continue as leverage against the West, there is no near-term resolution in sight. Energy costs at these levels feed directly into consumer prices, complicating an inflation fight the Fed had not yet won.

Threat #2: Stagflation Is No Longer a Tail Risk

This morning’s Q4 2025 GDP revision delivered a gut punch to the soft-landing narrative. Economic growth came in at just 0.7% annualized — down sharply from the prior estimate of 1.4% and well below the consensus forecast of 1.5%. That is the weakest quarterly growth reading in years, outside of the pandemic. Meanwhile, core PCE rose 0.4% month-over-month and February CPI held at 2.4% year-over-year. Slow growth paired with rising prices is the textbook definition of stagflation — historically one of the most punishing environments for equity markets. The 1973 OPEC oil crisis offers an uncomfortable parallel, when the S&P 500 fell more than 40% as recession and energy shock collided.

Threat #3: The Fed Has No Good Options

The Federal Open Market Committee meets March 17–18, and futures markets are pricing in just a 4.7% probability of a rate cut, according to CME FedWatch data. The Fed cannot cut into rising inflation driven by an oil shock, and it cannot hike into slowing growth. The result is policy paralysis — and markets hate uncertainty more than bad news. Rate-sensitive equities, particularly high-multiple tech names, are absorbing the most damage.

What the Headline Number Isn’t Telling You

While the cap-weighted S&P 500 is down 1.54% year-to-date, the S&P 500 Equal Weight Index is up 3.16% over the same period. That divergence reveals the selloff for what it is — a concentrated repricing of mega-cap technology, not a broad market collapse. The Russell 2000 small cap index outperformed Thursday, climbing over 1% on a day the Nasdaq posted losses. Energy, defense, financials, and domestically focused small cap names are holding ground while Big Tech reprices.

The macro environment is undeniably difficult. But for investors willing to look past the headline index, the rotation already underway may prove to be one of 2026’s most important opportunities.

The Great Rotation: Why Small Caps May Outshine Tech Giants in an Era of Debt Anxiety

As the Trump administration’s second term progresses, we’re witnessing a potential regime change in market dynamics. After years dominated by tech giants and trade war concerns, America’s mounting debt burden is now taking center stage.

From Tariff Wars to Debt Anxiety

Market sentiment is pivoting from U.S.-China trade tensions toward debt sustainability. With CBO projections showing U.S. debt potentially exceeding 120% of GDP by the mid-2030s and persistent budget deficits around 6% of GDP, investor psychology appears primed for a significant shift.

This isn’t merely academic—it has real implications for capital flows. As global reserve managers begin questioning the “risk-free” status of U.S. Treasuries, we could see demands for higher real yields or diversification into alternative sovereigns, keeping the long end of the U.S. yield curve stubbornly high.

The Magnificent Seven Losing Momentum

The market’s recent run has been fueled by a handful of technology giants. However, structural factors suggest these mega-cap stars may be losing steam, creating opportunities in the previously overlooked small-cap sector.

The mathematics of valuation makes this shift compelling: Big Tech stocks trade on multi-decade cash flow projections. When the term premium rises 100 basis points, these long-duration assets can see their DCF values erode by 10-15%. By contrast, small-cap earnings are front-loaded, making their valuations less sensitive to rate shocks.

Refinancing Reality

Companies that previously benefited from ultra-low borrowing costs now face a sobering reality. Many companies that recently refinanced debt must contend with significantly higher servicing costs.

This challenge extends to the federal level. U.S. government debt that once carried interest rates near zero is now being rolled over at 4-4.5%—representing a 50-60% increase in servicing costs and potentially accelerating debt anxiety.

The Small-Cap Advantage

Four structural factors suggest quality small-cap stocks could outperform:

  • Valuation Metrics: The Russell 2000 (ex-negative earners) has a forward P/E of approximately 14x versus the S&P 500’s 20x—a discount in the 15th percentile of the past 25 years.
  • Tax Policy: Large multinationals have historically benefited from profit-shifting strategies. As corporate tax policies adjust, domestic small firms—already paying close to statutory rates—may feel less relative impact.
  • Capital Allocation: Higher yields raise the hurdle for debt-funded buybacks that have powered S&P 500 EPS growth. Small caps, which tend to focus more on reinvestment, may gain a relative advantage.
  • Dollar Dynamics: The Russell 2000 derives approximately 80% of its revenue domestically. If debt concerns lead to dollar weakness, these companies may experience less FX pressure than multinational exporters.

Historical Patterns

Looking at previous episodes (1974-1979, 1999-2002, 2002-2006), we find a consistent pattern: periods of fiscal stress and rising term premiums have coincided with small-cap outperformance ranging from 22 to 70 percentage points over their large-cap counterparts.

Fixed Income Competition

As interest rates climb, bonds become increasingly attractive alternatives to stocks. This dynamic could particularly pressure tech giants’ lofty valuations, while reasonably valued small caps with strong fundamentals may hold up better in this competitive landscape.

A Stock Picker’s Market

We’re likely entering a “stock picker’s market” where the era of rising-tide-lifts-all-boats index investing is waning. If economic growth stagnates under the weight of debt concerns and higher interest rates, broad market indexes will struggle to deliver the returns investors have grown accustomed to over the past decade.

In this environment, the ability to identify individual companies with unique advantages becomes paramount. Those capable of spotting opportunities—particularly in the small-cap space where market inefficiencies are more common—stand to realize potentially outsized returns compared to passive index holders. As alpha generation becomes more challenging in mega-caps, skilled fundamental analysis and security selection will likely differentiate performance outcomes.

Risk of Market Consolidation

A significant risk in the current climate is prolonged sideways movement or consolidation in the broader market. This economic phenomenon occurs when asset prices increase even as the real economy shrinks—creating a disconnect between market valuations and underlying fundamentals. Such periods can be particularly challenging for index investors who rely on general market appreciation rather than specific security selection.

This environment of stagnant indexes coupled with pockets of opportunity may drive increased speculative interest in small-cap stocks. As investors search for growth in a growth-starved market, smaller companies with unique value propositions or disruptive potential could attract disproportionate attention and capital flows, creating both opportunities and volatility in this segment.

Investment Implications

For portfolio construction, this evolving landscape strengthens the case for quality small caps versus indexes dominated by duration-sensitive technology giants. Investors should focus on small companies with strong balance sheets, sustainable competitive advantages, and predominantly domestic revenue exposure.

As the market narrative shifts from tariffs to debt sustainability and broad index returns become more challenging, positioning ahead of this potential rotation and developing robust security selection capabilities could prove a prescient move for forward-thinking investors.

Why the Bullish Behavior of the Past May Return

Analyst Team Point Out Asset Classes that Slingshotted in the 1970s

While the traditional fine print usually says, “past performance is no guarantee of future results,’ we all know trading decisions, whether the stocks are to be held for seconds, or decades, are based on probabilities. And market probabilities are rooted in past performance. What does past performance tell us about the chances that the markets can survive high inflation and low growth? Well, if the stagflation of the 70s repeats, there may be a small section of the markets to keep a solid footing.

Michael Hartnett is the chief investment strategist at Bank of America/Merrill Lynch. Hartnett sees in our current economy the ingredients in the macroeconomic picture that lead to the difficult economic combination of high inflation and low growth. His team, in their Flow Show note on Friday, wrote:  “Inflation and stagnation was ‘unanticipated in 2022…hence $35 trillion collapse in asset valuations; but relative returns in 2022 have very much mirrored asset returns in 1973/74, and the 70s remain our asset allocation analog for 2020s.”

 If the conditions of the 1970s are being mirrored and we are creating a foundation similar to 1973/74, Hartnett and team have a list of assets that could springboard off the stagflation cycle.

The assets with potential include taking long positions in small-caps, value, commodities, resources, volatility, and emerging markets. The group also highlights the short positions that worked well in the 1970s, the note indicates these are larger stocks, bonds, growth, and technology.

Why Small-Caps

As it applies to the smaller companies, the note points out that stagflation persisted through the late 1970s, but the inflation shock had ended by 1973/74, when the small-cap asset class “entered one of the great bull markets of all-time.” The Hartnett team sees small-caps set to keep outperforming in the “coming years of stagflation.”

The current year-to-date status has the Russell 2000 small-cap stock market index (measured by iShares ETF) down 19.8% in 2022. At the same time, the Dow Industrials are down 11%, S&P 500 lost 21%, and the Nasdaq Composite gave back 33%.

The current state of the Fed and Chairman Powell is they continue to be adamant about tightening, Powell said he’d prefer to overdo withdrawing stimulus than do too little. He also knows that until the market believes this, his tightening efforts will have a lower impact.

The BofA team isn’t helping market expectations as they noted, despite Powell’s clear signal that the Fed isn’t ready to declare even a slight victory from its raising rates; the analyst team says, don’t give up on that pivot.

After tightening interest rates through 1973/74 amid inflation and oil shocks, the central bank first cut in July 1975 as growth turned negative, Hartnett points out. A sustained pivot began in December of that year, and importantly, the unemployment rate surged from 5.6% and 6.6% that same month.

The “following 12 months, the S&P 500 rose 31%. The note suggests the lesson learned is that job losses when they occur, will be the catalyst for a 2023 pivot,” said Hartnett and the team.

We’re not there yet. Today’s economic release on jobs showed the U.S. added a stronger-than-expected 261,000 jobs during October. This is a slower pace than the prior month’s 315,000 job gains but still shows the Fed can comfortably notch rates up more and continue reducing its balance sheet.

Take Away              

The team of analysts at BofA/Merrill Lynch, reporting to Michael Hartnett, drew conclusions from the stagflation and financial markets’ performance of the 1970s. They shared their thoughts in a research note with investors. Looking at past performance, their expectation is that the Fed will pivot away from aggressively raising rates when it begins to negatively impact job creation. At this point, many markets will have already reacted to inflation expectations and would then react to a more accommodative monetary policy.

The asset sectors to avoid or short are larger stocks, bonds, growth, and technology. The preferred sectors that, in past situations, have done well are small-caps, value, commodities, resources, volatility, and emerging markets.
