Markets climb wall of inflation worry as AI rally shrugs off the heat

The latest inflation report landed hotter than the central bank's comfort zone, yet equity markets ended the session firmly higher. The S&P 500 climbed, the Nasdaq outperformed, and the dollar index surrendered an early spike. The simple read – that sticky price pressures would force a hawkish repricing and crush risk assets – held for roughly an hour. The better read is that the AI capex cycle is creating an earnings stream that is less sensitive to the discount rate, and that transmission is now overriding the traditional rate-to-equity channel.

Inflation Data Rekindles Hawkish Repricing

The data showed core inflation running above the level that would justify imminent rate cuts. In the first 60 minutes, the 10-year Treasury yield jumped, rate futures pushed the first full cut further into the future, and the dollar index rallied. The naive macro transmission worked exactly as textbooks describe: higher inflation reduces the probability of near-term easing, lifts real yields, and attracts capital to the currency. USD/JPY briefly tested higher ground, and rate-sensitive equity sectors sold off.

That initial move, however, did not survive the New York morning. The dollar began to fade as equity futures reversed, and the yen weakened across the board. The transmission broke because the inflation impulse was absorbed by a separate force: the AI earnings trajectory.

AI Earnings Blunt the Rate Shock

While the bond market repriced the policy path, the equity market was already trading a different narrative. Semiconductor stocks and cloud-infrastructure names ripped higher, dragging the Nasdaq 100 to a gain that erased the early macro-driven dip. The mechanism is not that inflation is good for AI; it is that the capex commitments from hyperscalers are so large, and the revenue acceleration so tangible, that the sector's discounted cash flows are being recalculated with a lower equity risk premium – even as the risk-free rate ticks up.

This is the transmission that matters for positioning. When AI stocks rally hard enough to lift the entire index, the volatility surface compresses, and the carry trade re-engages. The dollar's rate advantage becomes less relevant when equities are screaming risk-on. The DXY reversal was not a dovish reinterpretation of the inflation data; it was a flow-driven unwind of the safe-haven bid that had built up in the prior week. DXY Rally Stalls After CPI; May Seasonality Keeps 99 in Play describes a similar pattern where the dollar's momentum faded once equity sentiment turned.

Dollar Reversal and the Carry Trade Reset

The dollar index finished the session lower, giving back all of its post-data gains. USD/JPY climbed as the yen weakened, a classic signal that the carry trade is back online. The Australian dollar and the New Zealand dollar caught bids, while the euro stabilized above a key support level. The transmission chain ran from AI stocks to lower implied volatility to a weaker dollar and a stronger appetite for high-beta currencies.

This sequence matters because it resets the forex market analysis framework. The dollar's direction is no longer a simple function of the rate differential implied by the inflation print. It is now a tug-of-war between the Fed's reaction function and the equity market's risk appetite. When the AI sector can shrug off a 10-basis-point rise in the 10-year yield, the dollar's safe-haven premium evaporates. The yen crosses become the cleanest expression of this dynamic: a hot inflation number that would normally send USD/JPY lower on haven demand instead sent it higher because the equity rally overwhelmed the rate move.

For traders, the practical takeaway is that the correlation between yields and the dollar has weakened when the equity move is driven by secular growth stories rather than cyclical reflation. The next data point will test whether this decoupling can persist. The upcoming personal consumption expenditures price index – the Fed's preferred inflation gauge – will land in an environment where the market has already priced out multiple cuts. If the PCE print confirms sticky inflation, the AI rally will face a sterner examination. A failure to hold the equity bid would quickly restore the traditional transmission, sending the dollar higher and punishing the carry trade. That is the next decision point, and it will determine whether the wall of inflation worry has truly been climbed or merely postponed.
