Robert Kaplan, the former president of the Federal Reserve Bank of Dallas and current vice chairman of Goldman Sachs, is sounding the alarm on inflation. His message is straightforward: if inflation prints don’t cool over the summer, the Fed will face mounting pressure to double down on price stability, even if that means keeping rates elevated longer than markets want.

The case for continued restraint

Kaplan’s argument centers on a simple premise. The Fed won’t consider cutting rates until there are noticeable improvements in inflation data.

Kaplan isn’t just some retired central banker musing from a beach chair. He joined Goldman Sachs in 1983, made partner by 1990, and has occupied the vice chairman seat since January 2021. When he speaks about Fed dynamics, he’s drawing on both sides of the fence: years running a regional Fed bank from 2015 to 2021, and years navigating markets at one of Wall Street’s most influential firms.

His current read on the economy points to strong GDP growth expectations, which sounds great until you remember that robust growth can be inflationary. A hot economy gives the Fed less room to ease, not more.

One element Kaplan is watching closely is an unprecedented capital spending boom in artificial intelligence infrastructure. The flood of investment into AI and computing represents a structural shift in how corporations allocate resources. Whether that spending ultimately proves deflationary, by boosting productivity, or inflationary, by competing for scarce resources, remains one of the most consequential economic questions of the moment.

Energy prices and geopolitical wildcards

Softening oil prices, Kaplan noted, might provide the Fed with some flexibility. But geopolitical tensions, particularly in the Middle East, have contributed to increased variability in energy price projections.

Stronger-than-expected inflation reports have consistently led to diminished expectations for rate cuts. At various points in 2026, markets have priced in fewer or even zero rate cuts for the year, driven largely by stubborn inflation readings and energy price fluctuations.

What this means for crypto and risk assets

When risk-free yields remain elevated, the opportunity cost of holding non-yielding assets like Bitcoin or Ethereum goes up. Institutional allocators have less incentive to chase returns in volatile markets when Treasury yields are doing the heavy lifting.

Kaplan’s comments didn’t explicitly address cryptocurrencies. The transmission mechanism is well-established at this point. A Fed that remains resolute on inflation control suppresses the liquidity conditions that digital assets thrive on.

The AI capital expenditure boom Kaplan highlighted adds another layer of complexity. Billions flowing into data centers, chip manufacturing, and computing infrastructure represent capital that might otherwise find its way into financial markets.

Ethereum and the broader altcoin market face even steeper headwinds. These assets tend to amplify Bitcoin’s moves in both directions, and a liquidity-constrained environment historically compresses altcoin valuations more aggressively than it does Bitcoin’s.
