Wall Street is bracing for a leadership shift at the Federal Reserve as Jerome Powell's term nears its end, with Kevin Warsh widely seen as a potential successor. Historically, such transitions have rattled markets. Research tracking Fed handovers over the past five decades shows equities underperforming by roughly 7.7 percentage points in the year following a leadership change. Yet, once macro factors like inflation, rates, and recession risk are accounted for, that impact shrinks sharply, suggesting markets are reacting less to the individual and more to the economic backdrop.

ETF Flows Signal Calm, Not Panic

This time, the ETF market is reinforcing that shift. Despite rising uncertainty, there is little evidence of a classic "risk-off" rotation. The SPDR S&P 500 ETF Trust (SPY) continues to anchor flows, indicating investors are maintaining core equity exposure rather than pulling back. Over the past month, SPY has seen inflows of nearly $18 billion, including $3.2 billion on May 1, per ETFDb.

Meanwhile, growth-heavy vehicles like Invesco QQQ Trust (QQQ) remain firmly in portfolios, pointing to a sustained appetite for megacap and AI-linked names even as policy transition risks build. The fund saw $8.6 billion in inflows in the past month.

The Missing Piece: Where Are The Bond Inflows?

What stands out is where money is not going. Traditional hedges like broad bond exposure via funds like iShares Core U.S. Aggregate Bond ETF (AGG), have seen notable outflows (over $3 billion) in the past 30 days, including a sharp pullback of almost $1 billion at the start of May, per ETFDb. In earlier cycles, Fed uncertainty would have triggered strong inflows into such core fixed-income ETFs. That playbook now appears to be breaking down.

Why This Time Is Different

What's fundamentally changed is the macro regime. For nearly two decades before the pandemic, markets operated in a low-inflation, falling-rate environment, where bonds reliably cushioned equity drawdowns. That relationship broke down in 2022, when both asset classes fell simultaneously for the first time since 1977, driven by aggressive rate hikes and persistent inflation.

When inflation becomes the dominant shock, it hits both sides of the portfolio at once, pushing bond yields higher while compressing equity valuations. As a result, in 2022, the traditional negative correlation flipped, weakening bonds' role as a dependable hedge.

That shift reflects a deeper structural change. Inflation and interest-rate volatility are now acting as common drivers across asset classes, meaning stocks and bonds can move in tandem during tightening cycles. With macro uncertainty, including supply disruptions and fiscal expansion, expected to persist, this correlation may remain unstable.

In such an environment, broad bond exposure is no longer a clean hedge but a source of its own risk, helping explain why investors are moving toward more targeted, strategy-driven positioning.

Historical patterns still suggest potential turbulence—drawdowns of around 9% within six months of a new Fed chair are not uncommon. But ETF flows indicate investors may already be braced for that scenario.
