Oil prices moved lower on Thursday, 29 October, as renewed diplomatic efforts involving the United States and Iran encouraged some investors to reassess the geopolitical risk premium embedded in crude prices.

Brent crude fell approximately 1.1% to $114.10 per barrel, while US West Texas Intermediate (WTI) declined around 1.3% to $101.45. The pullback reversed part of the previous session’s gains, although prices remained elevated amid continuing concerns about potential supply disruptions in the Middle East.

According to Reuters, US Vice President JD Vance reportedly sent a letter to Iran’s security council chief seeking to revive negotiations. Qatari mediators also presented Tehran with a draft proposal aimed at ending the conflict involving the United States and Israel. Iran indicated that diplomacy remained possible, although a senior official rejected the proposal in its current form.

The latest developments show how quickly crude prices can react to changing diplomatic expectations. When markets anticipate a possible reduction in conflict risk, traders may unwind some of the premium built into oil prices. However, a decline based on negotiation prospects does not necessarily mean that physical supply conditions have improved.

Supply Disruptions Remain a Major Market Risk

Despite the price retreat, the outlook for crude remains sensitive to events across the region. Concerns about intensifying Houthi attacks and possible threats to energy infrastructure and shipping routes continue to support prices. Reports of attacks targeting Saudi Arabia and Yemen have reinforced uncertainty about the security of regional supply chains.

Oil markets must balance two opposing forces. On one side, successful negotiations could reduce the probability of further disruptions and encourage prices to fall. On the other, an escalation in hostilities could threaten production, transport or export flows, potentially sending prices higher again.

This creates a market in which headlines can trigger sharp intraday moves without establishing a sustained trend. Traders may react to reports of negotiations, military developments and changes in supply expectations before the actual effect on production or exports becomes clear.

Other supply-side factors can also influence prices. Reuters reported that expectations of recovering Russian refinery activity and higher crude production weighed on prices, while US data showed crude inventories fell by 1.9 million barrels and gasoline inventories rose by 3.9 million barrels. These mixed signals underline the importance of assessing both geopolitical developments and underlying supply-demand data.

How Oil Prices Could Influence Inflation and Monetary Policy

Elevated oil prices can increase transportation, manufacturing and energy costs, potentially feeding into broader inflation. If energy costs remain high for an extended period, central banks may find it more difficult to bring inflation back to target without putting additional pressure on economic activity.

The Federal Reserve’s latest decision illustrates this challenge. The Fed held its benchmark interest rate at 3.75%–4.00% on Wednesday, while stating that inflation remained elevated. Two policymakers dissented in favour of raising rates, and the central bank upgraded its assessment of economic activity.

For markets, sustained energy-price pressure could complicate the outlook for future rate decisions. If oil rises further and contributes to persistent inflation, expectations for tighter monetary policy could strengthen. That may support the US dollar through interest-rate expectations, although the actual reaction will depend on broader economic data and how investors assess growth risks.

If oil prices decline meaningfully and remain lower, some inflation concerns may ease. However, a short-lived pullback driven by diplomatic optimism may not be sufficient to change central-bank expectations, particularly while supply disruptions remain possible.

Potential Impact Across Key Trading Instruments

• Crude oil — UKOIL and USOIL: Oil prices may remain highly sensitive to diplomatic headlines and evidence of actual supply disruption. Progress toward a credible agreement could reduce the risk premium, while renewed hostilities or threats to major shipping routes could push prices higher.
• Gold — XAUUSD: Gold may respond to the combined effects of geopolitical uncertainty, inflation expectations, Treasury yields and the US dollar. A reduction in immediate geopolitical risk could weigh on safe-haven demand, but persistent inflation concerns or fresh conflict escalation may provide support.
• US dollar — major USD pairs: The dollar’s response could depend on whether investors prioritise safe-haven demand or the interest-rate implications of higher energy prices. A renewed oil-price surge could strengthen expectations for tighter US monetary policy, while improving risk sentiment might reduce demand for the dollar as a defensive asset.
• US and global equity indices: Lower oil prices could ease cost pressures for transport, manufacturing and other energy-intensive businesses. Conversely, another sharp increase could weigh on margins and raise concerns about consumer purchasing power.

Key Catalysts to Watch

• US–Iran negotiations and any progress or breakdown in talks
• Regional security developments affecting energy infrastructure and shipping routes
• US crude and refined-product inventory data
• Production and refinery activity in major producing regions
• Inflation releases and central-bank signals on interest rates

Market Outlook: Volatility May Persist Until Supply Risks Become Clearer

The near-term outlook for crude oil remains dependent on the balance between diplomatic progress and the risk of further supply disruption. A credible agreement that reduces regional tensions could encourage prices to ease further. However, negotiations remain uncertain, and the threat of attacks or disruption continues to limit confidence in a sustained decline.

For traders, the distinction between headline-driven price movements and changes in actual supply conditions is particularly important. Diplomatic announcements can move prices quickly, but the durability of those moves will depend on whether they lead to measurable changes in production, transport and export flows.

Oil prices will also remain relevant to the broader market outlook because of their potential influence on inflation, monetary policy and investor sentiment. A sustained reduction in crude prices could ease some inflation pressure, while a renewed supply shock could complicate the policy outlook for central banks.

Market takeaway: The decline in oil prices reflects renewed hopes for diplomacy, but it does not eliminate the risk of supply disruption. Until negotiations and regional security conditions become clearer, crude markets may remain vulnerable to sharp moves in both directions.
