Oil Prices Plunge Over 7%: Why Is the US Dollar Under Pressure?​

APEX Market Structure Association | Forex Market Insights | November 3, 2026

Introduction: Oil Falls Sharply as Currency Markets Reassess Rate Expectations​

Global financial markets are experiencing a significant shift in sentiment as crude oil prices decline sharply.

On November 3, Brent crude fell more than 7% amid growing expectations of a possible diplomatic breakthrough between the United States and Iran.

The decline in energy prices has helped ease some inflation concerns, contributing to lower long-term US Treasury yields.

Meanwhile, the US Dollar Index traded around 101.76 during the Asian session.

EUR/USD edged higher toward 1.1185, while USD/JPY remained near 157.915.

This creates an interesting question for currency traders:

Why can falling oil prices put pressure on the US dollar instead of supporting it?

The answer involves inflation expectations, interest rate differentials and changes in global capital flows.

1. How Do Falling Oil Prices Affect the Dollar?​

Crude oil is a major component of global energy costs.

When oil prices rise, businesses may face higher transportation and production expenses.

These costs can eventually influence consumer prices and inflation expectations.

Conversely, a sharp decline in oil prices may reduce expectations of future energy-related inflation.

For currency markets, this matters because central banks consider inflation when setting monetary policy.

If inflationary pressure eases, investors may reduce expectations of further interest rate increases.

This can influence Treasury yields and the relative attractiveness of dollar-denominated assets.

However, the relationship between oil prices and the dollar is not always straightforward.

Currency movements also depend on economic growth, risk sentiment, market positioning and monetary policy expectations in other countries.

The key is understanding how energy prices influence broader expectations rather than assuming a fixed relationship between oil and currencies.

2. Why Are US Treasury Yields Important?​

US Treasury yields are an important reference point for international investors.

Higher yields can make certain dollar-denominated assets more attractive relative to assets offering lower returns.

When yields decline, that relative advantage may weaken.

Following the sharp decline in oil prices, longer-term Treasury yields came under pressure as investors reassessed inflation expectations.

However, falling yields do not guarantee sustained dollar weakness.

During periods of financial uncertainty, the US dollar can still attract safe-haven demand.

This creates a situation in which two competing forces influence the currency.

Lower yields may reduce demand associated with interest rate advantages, while risk aversion can support demand for liquid dollar assets.

For traders, identifying which factor dominates becomes an important part of market analysis.

3. EUR/USD and USD/JPY: What Should Traders Watch?​

EUR/USD: Can the Recovery Continue?​

EUR/USD moved slightly higher toward 1.1185 as the dollar softened.

However, a short-term recovery does not automatically confirm a bullish trend.

The euro remains sensitive to European economic conditions and European Central Bank policy expectations.

From a technical perspective, traders may monitor whether price can break a meaningful swing high and establish a sequence of higher highs and higher lows.

A failed breakout, followed by a return to the previous range, could suggest that buying momentum is weakening.

USD/JPY: Interest Rate Differentials Still Matter​

USD/JPY remained near 157.915 during early Asian trading.

The currency pair continues to reflect differences between US and Japanese interest rate expectations.

If US Treasury yields continue declining, the dollar's relative yield advantage could narrow.

This may provide some support for the Japanese yen.

However, safe-haven demand for the dollar and changing Japanese policy expectations could produce a different outcome.

Rather than assuming a particular direction, traders should monitor how USD/JPY reacts around recent structural highs and lows.

4. Reserve Bank of Australia: Another Important Event​

The Australian dollar is also in focus ahead of the Reserve Bank of Australia's monetary policy announcement.

Markets broadly expect the central bank to increase its cash rate by 25 basis points to 4.85%.

However, an anticipated rate increase does not necessarily guarantee Australian dollar appreciation.

If the expected outcome is already reflected in market prices, attention may quickly shift toward the central bank's future guidance.

A more hawkish policy message could support the Australian dollar.

Conversely, a rate increase accompanied by relatively cautious guidance could disappoint traders who had anticipated further tightening.

For AUD/USD, it is important to consider both the Reserve Bank of Australia's outlook and changes in US dollar expectations.

5. APEX Market Structure Analysis: Reading Price After Major News​

Sharp changes in oil prices and central bank expectations can generate substantial volatility in currency markets.

However, the first move following a major announcement does not always represent a sustained directional trend.

Three observations are particularly useful.

First: Has Price Broken a Meaningful Structural Level?​

A move beyond a previous swing high or swing low can indicate a potential change in market conditions.

However, traders should monitor whether price remains outside the previous range.

A quick return inside the range may suggest a false breakout or liquidity sweep.

Second: Is the Breakout Supported by Continued Pressure?​

A strong bullish or bearish candle does not always confirm sustained momentum.

Price may encounter opposing orders around important liquidity areas.

Order flow observations can offer additional context, but aggressive trading activity does not guarantee further price movement.

Third: Has a New Swing Structure Developed?​

A sequence of higher highs and higher lows can indicate improving bullish structure.

Lower highs and lower lows may suggest continued bearish pressure.

Because spot forex is decentralized, order flow information can vary between venues and data providers.

These observations should therefore be considered alongside broader price action and macroeconomic developments.

6. Two Possible Scenarios for the Dollar​

Scenario One: Dollar Weakness Continues

If oil prices remain under pressure, inflation expectations decline and Treasury yields continue falling, the dollar could experience further weakness.

A sustained technical breakdown in the Dollar Index would provide additional evidence of declining momentum.

Scenario Two: Safe-Haven Demand Supports the Dollar

If financial market volatility increases, investors may seek the relative liquidity and perceived safety of dollar assets.

This could support the currency even if Treasury yields remain lower.

Neither scenario is guaranteed.

The important question is which factor market participants begin to prioritize.

APEX Market Insight: Markets Trade Changing Expectations​

The latest oil price decline demonstrates how interconnected global financial markets have become.

Lower energy prices can influence inflation expectations.

Inflation expectations can affect future monetary policy assumptions.

Those assumptions can influence bond yields, currency valuations and investor positioning.

However, these relationships are dynamic rather than mechanical.

For forex traders, the challenge is to identify whether new information is producing a genuine change in market expectations.

A disciplined approach combines three perspectives:

1. Macroeconomic context: How are inflation and interest rate expectations changing?
2. Capital flows: What are bond yields and broader risk sentiment indicating?
3. Market structure: Does subsequent price action confirm a sustainable directional move?

Understanding the reason behind a market reaction is often more valuable than reacting immediately to the headline.

Conclusion​

The sharp decline in crude oil prices on November 3 has introduced another important variable into global currency markets.

The dollar remains sensitive to inflation expectations, Treasury yields and safe-haven demand.

At the same time, upcoming central bank decisions may create additional volatility in major currency pairs.

For traders, combining fundamental awareness with market structure analysis and disciplined risk management remains essential.

Do you expect lower oil prices to keep the dollar under pressure, or could renewed safe-haven demand support a recovery?
