Why Are Rising Oil Prices Making Investors Nervous?

Global equities started the week under pressure as investors confronted a combination of higher energy prices, escalating Middle East tensions and growing political uncertainty in Europe. Brent crude climbed 0.6% to around $97 a barrel, its highest level in seven weeks, after gaining almost 8% last week. The benchmark is now roughly 35% above its late-February level, before the conflict began.

The energy shock is extending beyond crude. Diesel, a critical input for transportation, shipping, agriculture and manufacturing, reached record levels last week and is now about 90% above its prewar price. That creates a potentially broader inflation problem because elevated fuel costs can feed into the prices of goods and services across the economy.

The latest geopolitical escalation added to those concerns. Iran said it plans to announce a restricted zone outside the Strait of Hormuz after US forces struck Iranian tankers and Iran launched ballistic missiles at two US Navy vessels.

Could Inflation Force Central Banks to Keep Raising Rates?

The combination of energy and food inflation is complicating the outlook for monetary policy. Investors are turning their attention to US consumer-price data later this week for evidence of whether the renewed energy shock is beginning to translate into broader price pressures.

Markets are increasingly anticipating rate increases from several major central banks. The European Central Bank is expected to raise rates to 2.75% Thursday, while derivatives imply a roughly 75% probability of another move to 3% by December. In Japan, markets are pricing approximately a 75% chance that the Bank of Japan raises rates by 25 basis points on September 18, with another move also seen as possible before year-end.

The Federal Reserve is facing similar pressure. August payrolls increased by 162,000, exceeding expectations, and markets now price a 58% probability of a rate increase at the September 16 meeting and around 70% for October.

As JPMorgan economist Bruce Kasman noted, central-bank patience had previously supported asset prices and the credit cycle. The growing energy shock, however, is forcing policymakers toward a more restrictive stance.

Why Is Europe’s Political Landscape Becoming a Market Risk?

Currency markets are also reflecting rising political uncertainty. The euro traded near $1.1625 but has struggled to maintain momentum after reaching three-month highs in August. The currency is down 1.1% against the dollar this year, making it the weakest-performing major currency, while the yen has gained 0.7% and the pound 0.4%.

Political developments are adding to the pressure. Germany’s Alternative for Germany surged into first place in Saxony-Anhalt’s state election, while French polls indicate Marine Le Pen remains a significant contender ahead of next year’s presidential election. Both developments raise questions about the future direction of European economic and currency policy.

For investors, the risks are becoming increasingly interconnected. Higher oil prices can reinforce inflation, inflation can delay monetary easing or trigger further rate increases, and political instability can weaken confidence in European assets. With European stocks already down around 0.1% and US futures showing limited movement amid a holiday-thinned session, markets appear to be waiting for confirmation from inflation data before making a stronger directional move.
