Global markets enter Friday, September 18, with a cautiously positive tone as investors digest the Bank of Japan’s latest rate hike, the Federal Reserve’s recent policy decision, easing oil prices and strong performance across US equities.

The Bank of Japan raised its policy rate by 25 basis points from 1.00% to 1.25%, bringing rates to their highest level in 31 years. However, the move had already been largely priced in and did not trigger a major risk-off reaction. Instead, the yen initially weakened, suggesting that investors did not interpret the decision as significantly more hawkish than expected.

At the same time, Brent crude has retreated from recent highs and the US 10-year Treasury yield remains below the psychologically important 5% threshold.

This combination continues to provide support for global risk assets, although volatility remains elevated.

US Markets: Equities Rebound Despite Fed Tightening

US equities staged a strong recovery on September 17 despite the Federal Reserve’s latest 25-basis-point rate increase.

The major indices recorded solid gains:

Dow Jones: approximately +0.64%
S&P 500: approximately +1.10%
Nasdaq: approximately +1.60%

Meanwhile, the US 10-year Treasury yield remained around 4.95%, below the critical 5% threshold.

This is particularly important for technology stocks.

As long as the 10-year Treasury yield remains below 5%, valuation pressure on technology and growth companies could remain relatively contained.

The short-term outlook for September 18 therefore remains constructive:

Nasdaq → Positive
S&P 500 → Positive
Dow Jones → Sideways / Positive

However, following the strong September 17 rally, some intraday profit-taking should not be ruled out.

Japan: BoJ Raises Rates to 1.25%

The Bank of Japan raised its policy rate from 1.00% to 1.25%, with the decision approved by a 7–2 vote.

The rate increase itself was largely expected.

The more important question for markets is now:

How quickly will the BoJ continue tightening monetary policy?

Market expectations suggest that the policy rate could reach approximately 1.50% by March 2027, with the possibility of additional tightening later.

This makes USD/JPY one of the most important indicators to monitor.

A more hawkish BoJ could create the following market mechanism:

BoJ Tightening → Yen ↑ → USD/JPY ↓ → Carry Trade Pressure ↑ → Global Volatility ↑

However, the yen’s initial weakness following the decision indicates that markets interpreted the BoJ’s message as relatively measured rather than aggressively hawkish.

For now, the probability of a major yen-driven carry-trade shock appears limited.

Oil: Lower Prices Provide Relief for Global Markets

Oil prices remain one of the most important indicators for global risk sentiment.

Brent fell approximately 1% on September 17 to around $104.82, while prices were near $103.77 on the morning of September 18.

Saudi Arabia’s efforts to maintain supply through alternative routes have reduced some of the market’s concerns over potential disruptions.

This creates an important positive mechanism for global markets:

Oil ↓ → Inflation Expectations ↓ → Bond Yields ↓ → Fed Pressure ↓ → Equities ↑

However, geopolitical risks have not disappeared.

Oil remains above $100, and renewed tensions involving Iran, Saudi Arabia, Yemen or the Houthis could quickly push prices higher again.

The critical thresholds remain:

Below $100 → Strongly positive for global markets

$100–$106 → Elevated but manageable

Above $110 → Significant inflation and risk-off concerns

Gold & Silver: Precious Metals Remain Strong

Precious metals continue to show remarkable resilience despite tighter monetary policy.

Spot gold rose approximately 2.07% on September 17, reaching around $4,350.

This is particularly notable because the move occurred while:

The Fed is tightening monetary policy
The BoJ is raising rates
The BoE continues to signal restrictive policy

Despite these headwinds, gold remains strong. This suggests that geopolitical uncertainty, central-bank demand and inflation concerns continue to provide significant support.

For September 18:

Gold → Positive

Silver → Strongly Positive

However, after the sharp gains recorded on September 17, investors should remain alert to potential short-term profit-taking.

US Dollar: Momentum Begins to Ease

The US dollar faces conflicting forces.

The Federal Reserve’s hawkish stance is supportive for the dollar, while the BoJ’s rate increase theoretically supports the Japanese yen.

However, because the BoJ decision was largely in line with expectations, the yen failed to strengthen significantly in the immediate aftermath.

Meanwhile, the dollar retreated from a seven-week high on September 17 as the US 10-year Treasury yield moved back below 5%.

The short-term outlook for the DXY remains sideways to slightly negative.

Global Market Outlook – September 18

The base scenario remains cautiously constructive.

Positive / Sideways-Positive Scenario

The report’s main scenario is supported by several factors:

US equities recovered strongly on September 17.

The US 10-year Treasury yield moved below 5%.

Oil retreated below $105.

The BoJ delivered the expected 25-basis-point rate increase.

The yen did not appreciate sharply following the decision.

Gold and precious metals remain strong.

Together, these factors create a relatively supportive environment for risk assets.

However, volatility could remain elevated because of BoJ-related yen movements, carry-trade concerns and expectations surrounding further Fed tightening.

Key Levels to Watch

Brent – $100

A move below $100 would provide significant relief for global markets by reducing energy-driven inflation concerns.

US 10-Year Treasury – 5%

As long as the yield remains below 5%, conditions remain more supportive for equities, particularly technology stocks.

USD/JPY

A sharp decline following the BoJ decision could signal increasing carry-trade unwinding risk.

Gold – $4,350–$4,400

Sustained trading around or above this region would indicate that safe-haven and precious-metal demand remains strong.

Nasdaq

Following the strong September 17 rally, Nasdaq will be an important indicator of whether global risk appetite can maintain its positive momentum.

Commodities Outlook

Commodity markets enter September 18 with a clear divergence between precious and industrial metals, which remain relatively strong, and several energy and agricultural markets facing greater short-term pressure.

The main commodity theme is:

Lower Oil Supply Risk + Strong Precious Metals + Diverging Agricultural Fundamentals

Oil: Mildly Negative / High Volatility

Oil faces short-term selling pressure as concerns over supply disruptions begin to ease.

Reports that part of the Saudi pipeline capacity affected by drone attacks could return within days have reduced some of the geopolitical supply premium.

The short-term bias therefore remains mildly negative, although geopolitical risk could limit the downside.

Any new attack or additional disruption could quickly reverse the move.

WTI

Support: $81–82
Upside: $83 → $84
Downside: $80 → $79

Brent

Support: $87–88
Upside: $89 → $90
Downside: $86 → $85

The near-term focus is therefore more likely to remain on price stabilization following the recent pullback rather than an immediate renewed rally.

Natural Gas: Neutral / Slightly Positive

Natural gas markets are awaiting the latest storage data.

The reaction will largely depend on how inventories compare with expectations:

Lower-than-expected storage build → Positive

Higher-than-expected storage build → Negative

Supportive weather conditions could also maintain upside momentum.

Key technical levels:

2.735–2.770 → Critical support / buying area

2.800 → Initial resistance

2.830 → Secondary target

Below 2.700 → 2.660 becomes possible

A sustained move above 2.770 would strengthen the near-term outlook.

Gold: Positive

Gold remains one of the strongest areas within the commodity complex.

The continuation of the precious-metals rally following the Fed decision suggests that gold continues to receive support despite tighter monetary conditions.

The fact that profit-taking in oil has not translated into significant weakness in gold is also notable.

Key levels:

$4,435–$4,450 → Important support / buying area

$4,525–$4,540 → First upside target

$4,580–$4,595 → Second upside target

A sustained break above $4,595 could open the door to another move toward record highs.

Silver: Strong Momentum Continues

Silver remains supported by three major factors:

Precious-metal demand

Post-Fed interest-rate expectations

Strength across industrial metals

Key levels:

$66.35–$66.85 → Support

$68.93 → Main short-term target

A high-volume break above $68.93 could strengthen upside momentum further.

Silver is likely to remain more volatile than gold, meaning that upside potential may also be accompanied by sharper corrections.

Copper: Supply Risks Support Prices

Copper remains supported by a combination of supply-side risks and broader strength across metals.

Although lower oil prices can reduce production-cost pressure for industrial commodities, supply concerns currently appear to be the stronger driver.

The underlying direction remains constructive, although profit-taking remains possible after recent gains.

Platinum, Palladium & Aluminium

Platinum continues to benefit from strength across precious metals following the Fed decision.

Key platinum levels include:

1,687.5 → Support

1,806.7 → 1,887.5 → 1,967.8 → 2,047.5 → Upside targets

A sustained move above 1,806.7 would strengthen the medium-term technical picture.

Palladium also remains supported by the broader metals rally, although volatility is high.

1,302.55 → Critical support

1,374.35 → First target

1,423.05 → Second target

1,480.10 → Strong upside target

Aluminium remains supported by supply-side concerns. Lower oil prices may provide some relief on production costs, but supply constraints remain the dominant factor.

Agricultural Commodities

Agricultural markets continue to show significant divergence.

Soybeans: Chinese demand remains the primary catalyst. Continued strong demand could support further upside.

Wheat: Black Sea trade uncertainty remains supportive, although comfortable global supply conditions and lower oil prices could limit gains.

Coffee: Brazilian production reaching the market more rapidly is increasing supply pressure, leaving the short-term outlook negative.

Cotton: Remains under pressure, with the near-term outlook negative.

Sugar: Slightly negative as weaker oil prices reduce the relative attractiveness of ethanol production.

Cocoa: Neutral, with no major directional catalyst currently dominating the market.

Corn: Slightly positive as Black Sea risks provide support, although lower oil prices may limit upside.

Bottom Line

Global markets enter September 18 with a cautiously constructive backdrop, supported by the strong recovery in US equities, the US 10-year Treasury yield remaining below 5%, easing oil prices and the absence of a major negative reaction to the Bank of Japan’s rate increase.

The BoJ’s move to 1.25% has not, so far, triggered the type of sharp yen appreciation or carry-trade unwind that could destabilize global risk assets.

At the same time, precious metals remain notably strong, while lower oil prices are helping reduce some of the immediate inflation pressure facing global markets.

The three most important indicators for the session are:

Oil remaining controlled around the $100–$105 region

US 10-year Treasury yields remaining below 5%

USD/JPY avoiding a sharp post-BoJ decline

If these conditions persist, the external backdrop should remain relatively supportive for US and European equities.

However, geopolitical developments, further BoJ guidance, oil-price volatility and potential profit-taking following the latest equity rally remain the main short-term risks.
