Nasdaq Today Live: The Nasdaq Composite came under renewed pressure on Tuesday, August 18, as rising Treasury yields, elevated oil prices and growing uncertainty surrounding the U.S.-Iran conflict weighed on technology and other rate-sensitive stocks.
According to Reuters, the Nasdaq Composite fell 1.06%, while the Dow Jones Industrial Average declined 0.12% and the S&P 500 dropped 0.49%. The three major U.S. indexes moved to roughly two-week lows during the session. The market weakness came as investors reassessed the outlook for inflation, borrowing costs and Federal Reserve policy amid renewed geopolitical risks.
Why Is The Nasdaq Falling Today?
A key factor behind Tuesday’s decline was a sharp move higher in longer-dated U.S. Treasury yields. Reuters reported that the 30-year Treasury yield touched 5.3371%, its highest level since 2007, before easing slightly. The benchmark 10-year Treasury yield also climbed to 4.7478%, its highest level since January 2025, before retreating. Higher yields can put pressure on growth and technology stocks because they increase borrowing costs and reduce the relative attractiveness of future earnings.Â
Oil Prices Add To Inflation Concerns
Oil prices remained another major concern for investors. Reuters reported that Brent crude reached its highest level since late July, while U.S. crude was trading around $84.75 a barrel.
The increase followed renewed uncertainty over the U.S.-Iran conflict and reduced expectations for an immediate diplomatic resolution. Higher energy prices can add to inflation pressures and complicate the Federal Reserve’s interest-rate outlook.Â
Federal Reserve Rate Outlook In Focus
Despite the rise in Treasury yields, recent softer U.S. economic data have reduced expectations for an immediate Federal Reserve rate increase.
Reuters reported that Fed funds futures were pricing a 31% probability of a September rate hike, while the odds of an increase by December stood at about 68%.
However, a renewed acceleration in inflation caused by higher energy prices could change those expectations. Investors are therefore closely watching oil prices, economic data and upcoming Fed signals for clues about the path of interest rates. Â
Treasury Yields Put Pressure On Technology Stocks
Technology shares were particularly vulnerable to the rise in bond yields. Reuters noted that heavyweight technology stocks helped pull Wall Street lower as investors became increasingly concerned about a tighter financial environment.
Higher yields can be especially significant for companies investing heavily in artificial intelligence infrastructure because those investments require substantial capital and may take time to generate returns.
The increase in borrowing costs therefore adds another layer of uncertainty for investors already assessing elevated valuations across parts of the technology sector. Â
Middle East Tensions Remain A Major Market Risk
The U.S.-Iran conflict has become an important driver of financial-market sentiment as investors assess the possibility of prolonged disruption to energy supplies.
Reuters reported that renewed tensions have pushed oil higher and increased concerns about inflation and the U.S. fiscal outlook. The strategic importance of the Strait of Hormuz has also kept energy-market risks firmly in focus.Â
Nasdaq Today Live: What Investors Should Watch Next
Investors tracking the Nasdaq are likely to focus on several key factors:
-
U.S. Treasury yields: Further increases could continue to pressure technology and growth stocks.
-
Oil prices: A sustained rise could revive inflation concerns.
-
Federal Reserve expectations: Markets will watch for changes in expectations surrounding September and December policy decisions.
-
U.S. economic data: Fresh figures could influence expectations for interest rates and economic growth.
-
Middle East developments: Any escalation or progress toward a U.S.-Iran agreement could quickly affect oil prices and broader risk sentiment.
-
Technology and AI stocks: Investors will continue assessing whether elevated valuations can withstand higher financing costs.

The Nasdaq’s decline on Tuesday highlights how quickly geopolitical developments and bond-market moves can affect technology-heavy indexes.
For now, investors are balancing softer U.S. economic data, which could support the case for lower rates, against higher oil prices and Treasury yields, which could keep inflation risks elevated.
The direction of the Nasdaq in the near term is therefore likely to remain closely tied to Treasury yields, oil prices, Federal Reserve expectations and developments in the U.S.-Iran conflict.
