US Fed Raises Rates Amid AI Overheating Concerns

The US Federal Reserve raised its benchmark rate by 0.25 percentage points, bringing it to a range of 3.75%-4.00%. This is the first increase since 2023. While the magnitude of the hike may not be disruptive, the key shift lies in the Fed's changed policy direction. Previously, markets expected rate cuts after temporary pauses, but this decision leaves open the possibility of further increases.

Fed Chair Kevin Warsh stated that inflation remains too high and has persisted for too long, with the US economy and labor market stronger than anticipated and financial conditions not sufficiently tight. The Fed prioritizes bringing down prices as the economy can handle rate hikes. Of 18 Fed officials, 12 believe at least one more increase is needed this year, while four advocate two additional hikes. The median projection for the year-end benchmark rate rose from 3.8% in June to 4.1%, with next year's forecast also increasing from 3.6% to 4.1%.

The AI boom has been fueled by low-rate expectations, but market valuations must distinguish between technological potential and corporate fundamentals. Similar to the dot-com bubble, internet technology transformed society, but stock prices outpaced actual growth. Today's AI sector faces comparable concerns as global firms invest heavily in AI chips, data centers, and power infrastructure without clear profits yet. Companies with unproven revenue still receive high valuations based on future potential alone.

Lower rates encourage such investments by allowing cheap capital access for companies and enabling investors to pay premium prices for distant growth. However, rising rates change the calculus: corporate interest burdens increase, new investment costs rise, and discounted future profits decrease. Higher yields on safer assets like US Treasuries reduce incentives to hold overvalued tech stocks.

AI-related equities could decline even as the industry grows if earnings don't meet expectations or investment costs exceed projections. The market's high valuations aren't justified by the industry's bright future alone. Stronger-than-expected US economic growth also complicates the picture, with the Fed projecting 2.3% GDP growth and a 4.1% unemployment rate alongside a 3.7% PCE inflation rate—well above its 2% target.

Crypto markets are similarly affected. Bitcoin maintains unique value through scarcity and decentralization, but short-term prices remain closely tied to global liquidity. Falling rates and increased market liquidity typically draw capital into risk assets, while rising rates and a stronger dollar may drive funds away. Altcoins lacking real users or revenue face greater pressure, especially those relying on high staking rewards and token price appreciation for user acquisition.

As the Fed's 0.25 percentage point hike signals longer-lasting elevated rates with potential further increases this year, AI stocks and crypto that have relied on low rates and abundant liquidity now face a new environment. Markets will increasingly weigh actual performance over expectations, distinguishing between genuine growth and excessive speculation in both sectors.
