When Inflation Cooling Becomes a Trap: Why the Devil Is Reversed This Time

The markets erupted on August 13, 2025, as the U.S. July CPI report dropped like a bombshell at 8:30 PM Beijing time. S&P 500 surged over 1%, Nasdaq soared past 1.23%, and both indices hit fresh records. Bitcoin and Ethereum jumped alongside equities. Everyone cheered—inflation is cooling, rate cuts are coming, prosperity awaits! But before you celebrate, ask yourself: have you really understood what the data is telling us? The devil, as they say, lives in the details. More troublingly, the devil is reversed—what looks like good news on the surface carries hidden dangers underneath.

The Data Paradox: Two Sides of the Same Coin

Let’s break down the July 2025 CPI numbers that sparked this market frenzy:

The headline CPI tells one story:

• Month-over-month: +0.2% (in line with expectations)
• Year-over-year: +2.7% (actually beating the 2.8% forecast)

This is the number Wall Street seized upon. Inflation cooling below 3%? Perfect ammunition for the Fed to start cutting rates. The market’s narrative wrote itself: soft landing achieved, economic troubles averted, bull market incoming.

But core CPI—the measure the Federal Reserve actually cares about—tells a completely different tale:

• Month-over-month: +0.3% (climbing, not cooling)
• Year-over-year: +3.1% (exceeding the 3.0% expectation)

Here’s where the devil reversed. When you strip away volatile food and energy prices, the stubborn underlying inflation remains elevated and sticky. The 3.1% core reading suggests that despite headline inflation appearing tame, the economic foundation still carries significant inflationary pressure. This is the devil in the details—the one traders initially ignored in their rush to chase risk assets.

Asset Markets React: The Schizophrenic Dance

The divergence in market reactions perfectly captures this tension. U.S. stock futures ripped higher on the “cooling inflation” headline, with traders choosing to believe the dovish narrative. The dollar index crumbled, fueling additional risk appetite across equities.

Yet bond markets displayed a distinctly nervous energy. The 10-year Treasury yield executed a dramatic V-shaped reversal. Initially plunging as traders bet on tame inflation supporting lower rates, the yield soon rebounded sharply as the 3.1% core CPI sank in. By session close, the yield settled around 4.29%, up on the day—a clear signal that bond traders remained unconvinced by the easing narrative.

This contradiction exposes a critical market risk: while stocks and crypto are pricing in rate cuts with ~94% confidence in September, they’re potentially dismissing the very real possibility that sticky core inflation could force the Federal Reserve’s hand into maintaining a higher-for-longer stance. The reversed devil scenario—where good news turns into bad news—lurks closer than most realize.

The Federal Reserve’s Hidden Dilemma

Inside Powell’s decision-making room, hawks and doves are locked in precisely the kind of debate this split CPI report was designed to amplify.

The dovish case seems compelling: Headline inflation has been subdued for months. The economy shows signs of cooling without cratering. Continuing to hold rates steady risks unnecessary economic pain. The urgency to cut rates before labor markets deteriorate is real and growing.

But hawks have legitimate ammunition too: That 3.1% core reading isn’t noise. It reflects genuine underlying inflation that hasn’t been conquered yet. Cutting rates prematurely could reignite exactly the kind of sticky inflation that took years to wrangle. One or two disappointments in future economic data, and the entire rate-cut narrative could evaporate overnight.

The market has chosen to believe the doves, with Wall Street banks from JPMorgan to Goldman Sachs now pricing September as the start of the cutting cycle. But here’s the dangerous assumption: they’re betting that future data cooperates. If August or September employment numbers come in hot, or if inflation ticks back up, the reversal could be swift and brutal.

Crypto’s Complicated Inheritance

Bitcoin and Ethereum participated in yesterday’s rally, but their participation lacked conviction compared to equities. This asymmetry has sparked intense debate across crypto communities:

The optimist camp believes September rate cuts represent the “lifeline” that will restore liquidity to risk assets, with crypto as the highest-beta beneficiary. Their conviction rests on the faith that once central banks shift to easing, the rising tide lifts all boats—and crypto boats have the most upside potential.

The realist camp sounds a more cautious note. They acknowledge that the 3.1% core CPI presents a genuine risk to the rate-cut thesis. If inflation surprises to the upside again, the market’s rate-cut expectations could reverse just as quickly as they formed. More importantly, they notice that crypto lags traditional markets in responding to macro positives, suggesting that liquidity transmission remains impaired. Until we see actual rate cuts executed, not just priced in, the crypto bull case remains speculative.

Altcoin speculators are already gaming the scenario. With Bitcoin’s near-term upside seemingly capped by macro uncertainty, they’re asking whether renewed optimism will cascade into smaller tokens and ecosystem plays. The search for the next outsized move has begun, fueled more by hope than fundamentals.

The Tactical Reality: Devil Reversed, Indeed

Here’s what the July CPI actually revealed: the devil reversed. What appeared to be unambiguously bullish data—inflation cooling—actually contains the seeds of a completely different outcome. If core inflation remains sticky and the Fed’s next move disappoints, the entire narrative flips.

For crypto investors, the lesson is sharp and simple:

Strategically, the long-term case for higher inflation and accommodative policy cycles remains intact. Central banks worldwide are trending toward easing, and that fundamental shift favors risk assets and alternative investments like crypto. This underlying conviction should anchor your conviction.

Tactically, treat this current rally as the beginning of a volatile and uncertain period, not as a foregone bullish conclusion. Macro data surprises are inevitable. Position sizing matters more than ever. The market has already priced in extraordinary optimism—September rate cuts, multiple expansion, liquidity restoration. Any deviation from this script will trigger sharp reversals.

The devil in this case isn’t just in the details of the CPI report. It’s in the reversal of expectations. Today’s ceiling of hope becomes tomorrow’s floor of disappointment. Stay strategic, stay patient, and most importantly, stay protected.
