Markets Pause After Nvidia Rally as Warsh Warns on Inflation and Investors Reassess the Fed

Markets

Global markets entered Friday with a more cautious tone after the powerful technology rally triggered by Nvidia's results.

European equities remained relatively firm, while U.S. futures were broadly mixed as investors waited for Federal Reserve Chair Kevin Warsh's keynote speech at Jackson Hole. The MSCI global equity index remains close to record levels and is heading toward a modest weekly gain, supported by technology stocks and falling oil prices.

The main question for markets is now whether the strength of the AI-driven economy can continue to offset persistent inflation and the possibility of tighter monetary policy.

Stocks & Earnings

Technology stocks remained the main driver of markets following Nvidia's exceptionally strong results. Nvidia shares surged sharply on Thursday, reinforcing investor confidence in the continuing AI investment cycle.

However, the enthusiasm has started to moderate. Marvell Technology fell despite beating earnings expectations, highlighting how demanding investors have become regarding valuations and future growth.

The market is increasingly separating companies that are genuinely benefiting from AI spending from those whose valuations have simply risen alongside the broader technology rally.

Nvidia remains the sector's most important reference point, but investors are now looking for evidence that the enormous investment in AI infrastructure will continue generating sustainable revenue and profits.

Business & Macro

Federal Reserve policy is the central macroeconomic story today.

Kevin Warsh delivered his highly anticipated Jackson Hole speech, emphasizing the importance of bringing inflation back toward the Federal Reserve's 2% target while also highlighting the need to respond to developments in the labor market.

The comments increased expectations of a possible rate hike. Markets moved from pricing roughly a 35% probability of a September increase to around 46% after the speech.

The two-year Treasury yield also moved higher, reflecting the increased probability of tighter monetary policy. Investors are now paying particularly close attention to upcoming employment and inflation data because the Fed appears increasingly determined to let economic data—not forward guidance—determine its next move.

Crypto & ETFs

Cryptocurrency markets remained relatively resilient despite the more cautious interpretation of the Fed's message. Bitcoin traded around the $79,000-$80,000 area, while Ethereum and other major digital assets remained sensitive to Treasury yields and the dollar.

Institutional demand remains an important support for the crypto market. Spot Bitcoin ETFs have attracted substantial inflows recently, reinforcing the idea that institutional investors continue to treat Bitcoin as an alternative asset alongside gold.

Technology and semiconductor ETFs also remain heavily influenced by Nvidia's results. A continued AI rally could support these products, although higher bond yields could create renewed pressure on growth-oriented funds.

Geopolitics

Oil prices continued to fall as markets assessed the possibility of increased flows through the Strait of Hormuz.

Brent crude traded around $89-$90 per barrel and is heading toward a weekly decline of roughly 5%. The decline reflects expectations that diplomatic progress involving Iran and Oman could gradually improve navigation through the strategic waterway.

Lower oil prices are an important positive for markets because they reduce the risk of another major inflationary shock.

However, the geopolitical situation remains fragile. Any breakdown in negotiations or renewed disruption to shipping could quickly push crude prices higher again and complicate the Federal Reserve's inflation fight.

What to Watch Today

Investors will closely monitor the market reaction to Kevin Warsh's Jackson Hole speech, along with shifting September Federal Reserve rate expectations and moves in U.S. Treasury yields, particularly the 2-year and 10-year bonds. Nvidia and semiconductor stocks will remain in focus after this week's rally, while oil prices and any developments surrounding the Strait of Hormuz could reshape inflation assumptions. Bitcoin's ability to remain close to the $80,000 level, institutional flows into Bitcoin and technology ETFs, and upcoming U.S. employment and inflation data will also be watched closely.

Bottom Line

Friday marks an important change in the market narrative. Nvidia has delivered the earnings strength investors wanted, but the Federal Reserve is now reminding markets that inflation remains the main obstacle to easier monetary policy.

The result is a more complicated environment for investors: strong AI growth is supporting equities, while higher rate expectations are putting pressure on valuations.

The decline in oil prices is helping by reducing inflationary pressure, and any further reopening of the Strait of Hormuz would provide an additional boost.

The market is therefore entering the final days of August with two competing forces: extraordinary AI-driven growth on one side, and a potentially more restrictive Federal Reserve on the other.
