Global markets entered September with a clear shift toward a risk-off and inflation-driven environment.

The main market chain is becoming increasingly important:

Oil prices ↑ → inflation expectations ↑ → bond yields ↑ → rate-hike expectations ↑ → equities ↓

This dynamic is now affecting equities, bonds, currencies and commodities across major markets.

Global Markets: Key Overview

Wall Street: Negative — Higher oil prices, Treasury yields and Fed expectations are pressuring equities.

Europe: Negative — Eurozone inflation rose to 3.3%, while higher energy prices are making monetary policy more difficult.

Japan: Cautious — The 10-year JGB yield reached around 3.00%, increasing concerns over global liquidity.

China: Relatively positive — Manufacturing activity improved, although geopolitical risks remain.

Oil: Strongly bullish — Brent moved toward the $95 area amid renewed Middle East and Hormuz-related supply concerns.

Gold: Short-term pressured — Higher yields and a stronger dollar are outweighing safe-haven demand.

Dollar: Strong — Risk aversion and expectations for tighter Fed policy are supporting the USD.

Bonds: Under pressure — Rising yields reflect growing inflation and rate-hike concerns.

1. Wall Street Faces Its First Major September Test

U.S. equities came under noticeable pressure, with the S&P 500 down around 0.7%, the Dow Jones 0.8% and the Nasdaq approximately 1%.

The key issue is not the decline itself, but the combination of higher oil prices, rising Treasury yields and increasing expectations for tighter Fed policy.

This environment is particularly negative for high-valuation technology and AI stocks.

The move does not yet confirm a broader bear-market trend, but the risk is becoming more significant than a normal seasonal September correction.

2. Oil Remains the Main Market Driver

Oil has become the most important variable across global markets.

Brent moved toward $95, while WTI reached around $90, supported by renewed geopolitical tensions and concerns over shipping activity through the Strait of Hormuz.

A sustained move above $90 could shift the market narrative from a temporary supply shock toward a broader inflation shock.

The key levels to watch are:

Brent $90 → $95 → $100

A move toward $100 would significantly increase concerns about inflation, interest rates and global growth.

3. Bond Markets Are Sending an Important Warning

U.S. 10-year Treasury yields moved toward 4.80%, while Japan’s 10-year yield reached approximately 3.00%, a level not seen since the 1990s.

Germany’s 10-year yield also moved higher toward approximately 3.34%.

Rising global yields may represent a more persistent risk for equities than oil prices alone, particularly if the trend continues.

4. Europe Faces an Inflation–Growth Dilemma

Eurozone inflation increased to 3.3% in August, with higher energy prices contributing to the increase.

This creates a difficult environment for the ECB:

Oil ↑ → Inflation ↑ → Rate cuts become harder

As a result, European equities remain under pressure and the STOXX 600 moved toward its lowest levels in roughly a month.

5. Japan Becomes Increasingly Important for Global Liquidity

The rise in Japanese government bond yields deserves close attention.

Higher domestic yields could reduce the incentive for Japanese investors to allocate capital abroad, potentially creating additional pressure on U.S. and European bonds and some emerging-market assets.

The 10-year Japanese yield is therefore becoming an increasingly important global liquidity indicator.

6. China Shows Some Improvement

China’s official manufacturing PMI improved from 49.2 to 49.8 in August, slightly exceeding expectations.

The private-sector PMI reached 51.5, pointing to improving industrial activity.

However, Chinese equities remain vulnerable to the broader deterioration in global risk appetite.

7. Gold Faces Short-Term Pressure

Gold declined by roughly 2% as higher Treasury yields and a stronger dollar outweighed geopolitical safe-haven demand.

The key mechanism is:

Oil ↑ → Inflation ↑ → Yields ↑ → Dollar ↑ → Gold ↓

Gold’s move below its 200-day average also creates a more cautious short-term technical picture.

However, the longer-term outlook remains supported by geopolitical risks, fiscal concerns and continued central-bank demand.

Short term: Negative / cautious
Medium to long term: Positive

The $4,300–$4,350 area is an important zone to monitor.

8. Commodity Markets Are Increasingly Diverging

Oil is clearly leading the commodity complex, while precious and industrial metals are facing short-term pressure from higher yields and a stronger dollar.

Brent / WTI: Strongly bullish

Wheat: Strongly positive, supported by Black Sea supply concerns.

Aluminum: Positive, supported by supply constraints and higher energy costs.

Soybeans: Positive, helped by improving Chinese demand.

Sugar: Positive, supported by supply concerns and biofuel dynamics.

Gold: Short-term pressured, medium-term positive.

Silver: More vulnerable than gold in the short term due to both monetary and industrial exposure.

Copper: Short-term pressured, but medium-term fundamentals remain positive due to electrification, AI infrastructure and energy-transition demand.

Platinum: Short-term pressured, medium-term constructive.

Palladium: More fragile due to automotive-demand concerns.

Coffee: Negative in the short term due to expectations of strong Brazilian production.

Cotton: Neutral to negative amid concerns over global growth and textile demand.

Cocoa: Short-term correction risk remains high, while medium-term fundamentals remain supportive.

9. The Fed Remains at the Center of Market Pricing

Markets are increasingly pricing a higher probability of a September rate hike, with expectations moving toward the 68% area.

The narrative has therefore shifted from:

“When will the Fed cut rates?”

to:

“Could the Fed raise rates again?”

The upcoming U.S. employment and inflation data will be crucial in determining whether this repricing continues.

10. The Most Important Market Combination

The four indicators currently moving in the same direction are:

Oil ↑
U.S. 10Y yields ↑
DXY ↑
Nasdaq ↓

This combination is generally negative for global risk appetite.

For now, our view is:

Short term: Negative
Medium term: Cautious

This does not yet confirm the beginning of a global bear market. However, sustained oil prices above $90 and Treasury yields around or above 4.80% could turn the September correction into a more significant global risk event.

What to Watch Next

1. Whether Brent remains above $90.

2. Whether U.S. 10-year yields remain above 4.80%.

3. Whether September Fed hike expectations move toward 70–80%.

4. The upcoming U.S. employment data.

5. Whether U.S. inflation reflects the renewed energy shock.

6. Whether the Nasdaq decline spreads beyond technology stocks.

7. Whether Japan’s 10-year yield remains above 3%.

Bottom Line

September 2026 is increasingly shaping up to be less about the traditional “September effect” and more about the interaction between oil, inflation, bond yields, monetary policy and high equity valuations.

The most important variable remains oil. If Brent stays above $90 and approaches $95–100, the resulting inflation and interest-rate pressures could increasingly weigh on global equities and industrial metals.

At the same time, if the oil shock becomes persistent enough to raise stagflation concerns, gold and silver could eventually regain strength as defensive assets.

For now, we view the market as short-term negative and medium-term cautious, rather than declaring the start of a new global bear market.
