Given market volatility and rising interest rates, is now a good time to invest in stocks?
President Donald Trump signed the Lindsey O. Graham Sanctioning Russia and Iran Act on September 18, 2026. The new law permits tariffs as high as 100% on products originating from countries that bypass sanctions or import Russian energy.
Why it matters
The legislation introduces significant trade pressure on major economies that continue to purchase Russian oil, such as China and India. This shift adds to global market volatility currently driven by elevated bond yields and tensions in the Middle East.
The 10-year Treasury yield is currently above 5%, while August consumer prices rose 3.4% year-over-year. These figures come alongside a producer price increase of 5.4% during the same month.

Macro View
The signing of the Lindsey O. Graham Sanctioning Russia and Iran Act marks a significant departure from previous trade policies by authorizing duties of up to 100%. This expansion of executive authority mirrors historical protectionist cycles that have previously influenced global supply chains.
The combination of high producer prices and rising interest rates may increase borrowing costs for businesses and consumers worldwide. Readers should monitor how these trade duties affect the retail pricing of imported goods in the coming months.
The takeaway
Investors should watch for shifts in semiconductor stock performance as a bellwether for index stability following the recent rebound. Heightened geopolitical tensions suggest that market volatility related to oil prices and international sanctions will remain a primary focus for the near future.
What happens next
President Xi Jinping is expected to visit Washington on September 24, 2026, where potential removal of a 15% tariff on liquefied natural gas may be discussed. Additionally, the Federal Reserve may deliberate on a further interest rate hike in October 2026.
