Mainstreet Synergy Group – Global Market & Economic Weekly Report

Week Ending August 28, 2026

Global Market & Economic Overview

Global financial markets ended the final full week of August with investors focused on three major themes: U.S. Federal Reserve policy, persistent geopolitical risks surrounding the Middle East and Strait of Hormuz, and continued strength in artificial intelligence and technology-related equities.

The week began with strong investor interest surrounding NVIDIA's earnings and outlook for continued AI-related spending. NVIDIA's results helped fuel a broad technology rally, particularly in the United States and Asia. However, market sentiment became more cautious Friday following Federal Reserve Chair Kevin Warsh's address at the Jackson Hole Economic Symposium.

Warsh emphasized that the Federal Reserve remains committed to bringing inflation back toward its 2% target and indicated that additional policy tightening could be necessary if inflation does not demonstrate sufficient progress. Following the speech, market-implied odds of a September rate increase rose materially, while Treasury yields moved higher.

The result was a modest pullback in U.S. equities on Friday, although all three major U.S. indexes still finished the week higher. The S&P 500 gained approximately 0.5% for the week, the Dow gained approximately 0.5%, and the Nasdaq Composite gained approximately 0.8%.

Internationally, European equities finished the week on firmer footing, while Asian markets were mixed. Middle Eastern markets continued to trade against a backdrop of geopolitical uncertainty, particularly surrounding Iran and the Strait of Hormuz.

Headline Global & U.S. Economic News

United States

Federal Reserve Signals Continued Inflation Fight

Federal Reserve Chair Kevin Warsh used his first Jackson Hole address to reinforce the Fed's commitment to price stability. Warsh indicated that the central bank has more work to do if it cannot gain confidence that inflation is returning toward the Fed's 2% objective. The comments increased market expectations for a possible September rate hike.

Technology and Artificial Intelligence Remain Major Market Drivers

NVIDIA's latest earnings and forward guidance provided another boost to investor confidence in AI-related spending. The company's outlook helped technology stocks rally earlier in the week, although some of those gains reversed Friday as investors focused on higher interest-rate expectations.

U.S. Consumer Sentiment Improves

The final University of Michigan consumer sentiment reading for August increased to 51.7, compared with a preliminary reading of 51.0. The improvement provided a modest positive signal for the U.S. consumer heading into the fall.

Canada

Canada's economy showed stronger-than-expected growth, but Canadian equities were pressured Friday by weakness in mining and materials stocks as investors continued to monitor trade tensions with the United States.

The S&P/TSX Composite declined approximately 0.76% on Friday to close at 36,553.92, producing a second consecutive weekly decline.

Europe

European markets recovered Friday following a difficult session earlier in the week. The STOXX 600 gained approximately 0.5%, while France's CAC 40 rebounded nearly 1%.

France remained a significant area of concern for investors because of fiscal deficits, political uncertainty and rising borrowing costs. French preliminary harmonized inflation increased to 2.7% year-over-year in August, up from 2.4% in July, primarily because of higher energy prices.

Germany's DAX remained one of Europe's stronger major indexes, while investor attention continued to focus on the interaction between European inflation, fiscal policy and global interest rates.

United Arab Emirates & Middle East

Gulf markets remained highly sensitive to developments involving Iran, the United States and the Strait of Hormuz.

On Thursday, Dubai's benchmark index gained approximately 0.3%, while Qatar's index advanced 0.2%. Abu Dhabi was little changed, and Saudi Arabia's benchmark declined 0.2%, ending a seven-session winning streak.

A proposed temporary shipping corridor involving Iran and Oman remained an important development for energy and transportation markets. Any sustainable reopening of the Strait of Hormuz would potentially reduce risk premiums in oil and shipping markets.

However, Iran's Revolutionary Guards stated Friday that Iran maintains what it described as "full control" of the Strait, underscoring the continuing geopolitical uncertainty surrounding the world's critical energy corridor.

Asia-Pacific

Asian markets were mixed as investors balanced the technology rally generated by NVIDIA against concerns about U.S. interest rates and global economic conditions.

• Japan: The Nikkei 225 advanced approximately 0.4% Friday, continuing to trade near historically elevated levels. Investors remain focused on Japanese monetary policy, the yen and the potential spillover from U.S. interest-rate decisions.

• Hong Kong: The Hang Seng Index finished modestly higher as technology shares provided support.

• South Korea: The KOSPI declined approximately 1.8% Friday as technology-sector momentum cooled.

• Singapore: The Straits Times Index gained approximately 0.3%, demonstrating relative resilience compared with several other Asian markets.

• China: The Shanghai Composite slipped modestly as investors continued to assess China's economic outlook and technology-sector valuations.

  
  

Asian equities were broadly cautious Friday ahead of and following Warsh's Jackson Hole remarks, with investors particularly sensitive to U.S. Treasury yields and currency movements.

Cryptocurrency Market

Cryptocurrency markets experienced increased volatility as investors reassessed risk following the week's strong rally and the Federal Reserve's more hawkish tone.

Current Cryptocurrency Prices – August 29, 2026

• Bitcoin (BTC): approximately $77,686

• Ethereum (ETH): approximately $2,437

• XRP: approximately $1.39

Bitcoin fell below $78,000 over the weekend after reaching above $81,000 earlier in the week. The recent decline has occurred alongside a notable increase in Bitcoin's correlation with gold.

Ethereum also experienced significant volatility after a strong August rally. Meanwhile, XRP attracted substantial institutional interest, with spot XRP ETFs recording approximately $110.5 million in net inflows during the week ending August 28, the strongest weekly inflow of 2026.

Commodity Markets

Crude Oil

• WTI Crude Oil – October 2026: $83.40 per barrel

• Friday change: -0.16%

• Weekly performance: approximately -4%

• Brent Crude: $89.31 per barrel

• Weekly performance: approximately -5%

Oil prices declined for the week despite continued geopolitical risk surrounding the Middle East. Investors focused on the possibility of improved shipping conditions through the Strait of Hormuz, while also assessing the implications of potentially higher U.S. interest rates.

The Strait of Hormuz remains particularly important to global energy markets because approximately one-fifth of global oil supplies historically moved through the waterway.

Gold

• Gold Futures – December 2026: $4,529.90 per troy ounce

• Friday change: -2.88%

Gold experienced a sharp decline Friday as higher Treasury yields and a stronger U.S. dollar reduced some of the appeal of non-yielding assets. Despite the weekly volatility, gold remains significantly higher over the longer term.

Agriculture & Agricultural Commodities

Agricultural markets received several important signals during the week.

The USDA reported strong demand for U.S. soybeans heading into the 2026/27 marketing year. Weekly soybean sales totaled approximately 2.48 million metric tons, compared with 1.72 million metric tons the previous week. China accounted for approximately 1.1 million metric tons of the purchases.

Earlier in the week, USDA crop-condition data showed some deterioration in U.S. corn and soybean conditions:

• U.S. corn rated good/excellent: 57%, down from 60% the previous week.

• U.S. soybeans rated good/excellent: 60%, down from 61% the previous week.

• Corn maturity and soybean pod development continued to advance as the growing season moved toward harvest.

The combination of strong export demand and changing crop conditions will remain important for agricultural commodity prices heading into the fall harvest season.

U.S. Bond Market

The U.S. Treasury market was one of the week's most important indicators as investors reassessed the probability of a September Federal Reserve rate increase.

Friday, August 28, 2026

• U.S. 10-Year Treasury Yield: 4.72%

• Daily change: approximately +4 basis points

• U.S. 30-Year Treasury Yield: 5.21%

• Daily change: approximately +2 basis points

Yahoo Finance reported the 10-year Treasury yield at 4.72% and the 30-year yield at 5.21% at Friday's close.

The increase in yields followed Warsh's Jackson Hole remarks and reflected greater expectations that the Federal Reserve could maintain or increase restrictive monetary policy if inflation remains elevated. Market-implied expectations for a September rate hike rose to approximately 57% following the speech.

The elevated 30-year Treasury yield remains particularly important for businesses, commercial real estate, mortgages and long-term capital allocation because it represents a significant component of long-term borrowing costs.

Closing Statement & Looking Ahead

As August comes to a close, financial markets enter September facing several competing forces.

The U.S. economy continues to demonstrate resilience, while inflation remains above the Federal Reserve's 2% objective. At the same time, corporate earnings—particularly within technology and artificial intelligence—continue to support equity valuations.

The key issues for investors heading into September include:

• The upcoming U.S. employment report and inflation data.

• The probability of a Federal Reserve rate hike at the September meeting.

• The direction of U.S. Treasury yields.

• Continued investment in artificial intelligence infrastructure.

• Developments surrounding the Strait of Hormuz and Middle Eastern energy markets.

• U.S.-China and U.S.-Canada trade relations.

• European fiscal and political developments, particularly in France.

• Agricultural harvest conditions and global grain demand.

• Continued institutional participation in cryptocurrency markets.

  
  

The combination of elevated equity valuations, persistent inflation, higher long-term interest rates and geopolitical uncertainty suggests that volatility may remain elevated as investors enter the final months of 2026.

For businesses, families and investors, the current environment reinforces the importance of maintaining adequate liquidity, diversification and a disciplined long-term financial strategy.
