When Economic Stimulus Hits Diminishing Returns: The Fed Rate Cut Paradox Nobody Wants to Discuss

The Federal Reserve’s potential September rate cuts have ignited fresh optimism across markets, with Bitcoin and Ethereum surging on the news. Yet beneath this bullish sentiment lies a more complex reality that deserves scrutiny. The real question isn’t whether rate cuts will happen—it’s whether they’ll actually move the needle in an economy already saturated with stimulus.

Powell Signals the Path, But the Landscape Has Shifted

During his Jackson Hole speech, Fed Chair Jerome Powell telegraphed openness to rate adjustments, noting that “downside risks to employment are rising” and suggesting that “with policy in restrictive territory, the baseline outlook and the shifting balance of risks may warrant adjusting our policy stance.” The market took this as a green light, sending equities and digital assets higher in anticipation.

But here’s the disconnect: this rate-cut cycle is arriving at a moment when the economic stimulus dial is already cranked to maximum. Record fiscal spending persists near 23-25% of GDP—levels maintained well above pre-pandemic norms. Global M2 money supply remains elevated. Stock and cryptocurrency valuations sit at historic peaks. Volatility across assets has compressed to minimal levels.

The founders of LondonCryptoClub captured the tension perfectly: “Rate cuts will have incremental impact, but the real drivers are global monetary easing and massive fiscal stimulus. The U.S. continues running wartime-level deficits exceeding 6% of GDP. Meanwhile, Treasury QE—where debt issuance front-loads short maturities to artificially suppress yields—keeps the system awash in liquidity.”

In essence, the U.S. Treasury has been strategically concentrating debt issuance into short-term securities, maintaining artificially depressed short-duration yields. It’s a form of monetary engineering that props up asset prices without building genuine economic foundation.

Five Years Without a Reset: The Economy on Permanent Overdrive

Consider the U.S. economy as a system in a state of continuous artificial enhancement. For over five years, policymakers have cycled between monetary steroids and fiscal steroids without meaningful intermission. When the Federal Reserve paused rate hikes in 2022-23, fiscal policy accelerated dramatically. Now, with rate cuts potentially incoming, the combined stimulus cocktail threatens to intensify further.

Real economies, like biological systems, have natural feedback mechanisms. Prolonged stimulus produces diminishing returns—what economists call the law of diminishing marginal utility in action. Each successive dose of monetary or fiscal stimulus generates less economic benefit than the previous one, while systemic side effects—asset bubbles, debt accumulation, inflation persistence—compound.

The pattern mirrors what happens in overextended systems: initial interventions work powerfully. The second wave of stimulus provides noticeably less lift. By the fifth or sixth consecutive year, you’re operating in diminishing marginal utility territory where growth barely budges while risks multiply exponentially.

The Saturation Point Nobody Wants to Acknowledge

Economists from JPMorgan to Bianco Research have repeatedly warned of “stimulus fatigue.” David Kelly described the 2020 COVID recovery as “a steroid kind of recovery”—potent in the moment but destined to decelerate as artificial support wears off. Yet the support never truly wore off. Instead, it evolved: pausing one form of stimulus while unleashing another.

The Congressional Budget Office forecasts elevated fiscal spending will persist for years. Planned tax cuts and infrastructure spending threaten to add trillions more to deficits. Meanwhile, the Fed stands ready to add rate cuts back into circulation.

This creates a peculiar paradox: when you’re already operating in a diminishing marginal utility environment, adding more of the same medicine doesn’t restore vitality—it merely postpones the inevitable adjustment while accumulating collateral damage.

Why Traders Should Stay Alert

The real risk isn’t that rate cuts fail to materialize. It’s that they arrive precisely when their effectiveness has already diminished to marginal levels. Price action may spike initially on the announcement, but the underlying economic mechanics remain constrained. Assets already priced at record valuations leave limited room for fresh incremental gains from cheaper borrowing costs alone.

Traders watching price behavior relative to short-term moving averages would be wise to brace for volatility spikes followed by potential sell-offs, as the market grapples with the reality that stimulus—no matter how aggressively deployed—eventually hits a wall. The law of diminishing marginal utility doesn’t exempt central banks or treasury departments from its logic.

The question haunting markets isn’t whether the Fed will cut rates. It’s whether rate cuts in an already hyper-stimulated economy will deliver the expected uplift—or whether we’re witnessing the tail end of a very long stimulus cycle reaching its natural saturation point.
