• Bank of America (BAC)'s Michael Hartnett expects investors to reduce risk over the next 3–4 weeks, citing 3% real yields, persistent inflation, AI valuation concerns, and U.S. midterm election uncertainty.
  • Hartnett forecasts an October Fed rate hike, despite markets increasingly pricing in a pause, and favors small caps, REITs, and consumer discretionary while avoiding additional technology exposure.
  • The warning comes as September's hotter-than-expected inflation report strengthens the case for further tightening, though an October hike remains a forecast, not a certainty.

A Defensive Stance

Bank of America's chief investment strategist, Michael Hartnett, is urging investors to brace for a risk-off period over the next three to four weeks, pointing to a confluence of pressures: real yields hovering around 3%, stubborn inflation, stretched AI valuations, and uncertainty surrounding the upcoming U.S. midterm elections. Hartnett also expects the Federal Reserve to raise rates again in October, even as market pricing has shifted toward a pause.

"What institutional investors like us are really focused on is regulatory stability," Hartnett said in a recent note, though his broader message was far from reassuring. He recommends rotating into small caps, REITs, and consumer discretionary names—sectors that could benefit if yields eventually peak—while steering clear of adding to technology exposure, where positioning remains crowded.

Inflation Reignites Rate Fears

The most immediate catalyst for Hartnett's caution is September's consumer price index, released on October 14. CPI rose 0.6% month over month and 3.7% year over year, up from 3.4% annually in August. Core CPI, which excludes food and energy, increased 0.3% monthly and 2.6% annually. Both annual readings exceeded expectations, sending stock futures lower and bond yields higher.

Following the release, futures markets briefly priced a 54% probability of an October hike, up from roughly 22% previously, though that figure has since drifted to around 30%. The Fed's next meeting is scheduled for October 27–28, and minutes from September showed policymakers unanimously raising the federal-funds target range to 3.75%–4%, with most participants favoring another increase by year-end. They stopped short of committing to October.

Cash on the Sidelines

Hartnett's defensive posture predates the latest inflation data. As of October 9, his team was already positioned cautiously ahead of the midterms, with Bank of America's Bull & Bear Indicator stuck in "sell" territory. Money-market funds attracted $166.4 billion in the week through October 7, pushing total assets to approximately $8 trillion—a clear sign of strong demand for cash. Hartnett's team estimates these funds are generating roughly $330 billion in annual interest income, which helps explain why investors may remain reluctant to shift into riskier assets without sustained easing.

The Fed's September minutes also highlight uneven effects from higher rates. Financing conditions remain generally accommodative for large companies but have turned somewhat restrictive for mortgage borrowers and small businesses. That dynamic helps explain both the vulnerability of smaller companies today and Hartnett's interest in them if yields eventually peak. Meanwhile, heavy AI-related debt issuance has contributed to higher Treasury yields and term premiums, even as AI investment continues to support business spending.

Political and Global Crosscurrents

Hartnett has explicitly linked the midterms to taxes, regulation, and the AI investment cycle. In an October 9 note, he outlined sharply different scenarios: more than 10% equity downside after a Democratic sweep of Congress, versus more than 5% upside if Republicans retain the Senate while losing the House. Those are his conditional market scenarios, not consensus forecasts. He also suggested international equities could outperform under some election outcomes.

The pressure is not confined to the U.S. The Fed reported above-target inflation across many foreign economies, and the European Central Bank recently raised rates, citing inflationary effects from the Middle East conflict. This is a broader tightening environment, not solely a U.S. election trade.

Bank of America's Own Mixed Quarter

While Hartnett's warning concerns market strategy rather than corporate results, Bank of America's latest earnings illustrate the mixed effects of higher rates. Third-quarter revenue came in at approximately $30 billion, up 3% year over year, with net income of $6.93 billion, or $0.91 per share. Excluding a roughly $1.2 billion regulatory penalty for failures in money-laundering safeguards, earnings were $1.08 per share, below the roughly $1.10 consensus estimate. Net interest income rose 8% to $16.4 billion, but fixed-income trading revenue fell 17%, which management attributed partly to sharply higher rates. BofA shares fell about 4.7% on October 14 following the results and penalty—a move tied to company-specific issues, not Hartnett's outlook.

What to Watch

The coming weeks will test Hartnett's call. The October 27–28 Fed decision, evolving bond yields, credit conditions, earnings, and the midterm election all loom large. If inflation moderates and yields peak, the rate-sensitive assets Hartnett is selectively buying could benefit. If inflation persists, further tightening could prolong pressure on borrowing-sensitive businesses and investments. The Fed's September staff outlook still projects solid growth and eventual inflation convergence to 2% by 2029, but explicitly judges inflation risks to be tilted upward. AI productivity gains could help over time, though policymakers stress uncertainty about their timing and magnitude.

For now, Hartnett's message is clear: the near-term path for risk assets looks rocky.

Correction: An earlier version of this article misstated the date of the September CPI release. It was October 14. Additionally, the probability of an October rate hike has fluctuated since the inflation report; the 54% figure was a snapshot immediately following the release.
