Oil Jumps, Futures Drop On Fresh Iran Strikes, Hormuz Confusion

Oil jumped and US equity futures fell after the US launched another round of strikes against Iran, while conflicting claims over the status of the Strait of Hormuz heightened uncertainty.

S&P 500 futures dropped 0.2% in early trading Monday after the cash index closed 0.4% higher on Friday.

WTI crude climbed 3% at the open, trading around $74, while the dollar rose against most major peers. 

Risk crept in after the US military launched several rounds of strikes in recent days, culminating with the latest barrage around 5pmET on Sunday aimed at further weakening Iran’s ability to strike civilian vessels transiting the Strait of Hormuz, the US Central Command said. The latest action followed Iranian drone and missile attacks on US allies including Kuwait, Jordan and Qatar in response to earlier US strikes. 

At 5 p.m. ET today, U.S. Central Command forces began launching more strikes against Iran to continue degrading their ability to attack civilian mariners and commercial ships freely transiting the Strait of Hormuz. The Commander in Chief has directed the strikes to hold Iranian…

Confusion over the status of the Strait of Hormuz only added to the uncertainty, after Iran said it had closed the waterway while the US military and maritime authorities said shipping continued through its southern route. According to Axios, a US official said "around 20 commercial vessels transited through the Strait of Hormuz in coordination with the US military over the last 24 hours, in addition to several vessels without US coordination."

“The latest developments over the weekend suggest markets may face a volatile start to trading which could test the glass half full mentality we have seen recently,” Nick Twidale, chief market analyst at AT Global Markets, wrote in a note to clients.

Besides a return to hostilities, investors are also bracing for a pivotal earnings season, with results from JPMorgan, BofA, Citi, Goldman and Wells all due Tuesday. According to Bloomberg, S&P 500 companies are expected to post a 24% jump in second-quarter profits, though the benchmark’s rally has become increasingly reliant on gains outside the technology megacaps that have driven markets in recent years.

In Europe, Deutsche Bank expects Stoxx 600 firms to report a 12% jump in second-quarter earnings, following a 7% rise in the first quarter. Profits for MSCI Asia Pacific constituents are estimated to rise 39%, up from 6.9% in the previous three months, largely driven by chip-exporting powerhouses such as Korea and Japan. 

The outlook is being tested by persistent inflation, higher energy prices and growing expectations the Federal Reserve may resume raising interest rates, threatening corporate margins. Just last week, several Fed officials warned that surging memory prices are rising core inflation, with Goldman calculating that the impact on core PCE by year-end will be +0.5% due to surging chip costs.

With US and global equities trading near record highs and valuations elevated, investors see little room for disappointing results.

Investors will also keep a close eye on this week's US CPI data, after oil’s biggest weekly gain since mid-May revived concerns that higher energy costs could further complicate the disinflation story. Consumer and producer price reports - the last inflation readings before the Fed meets later this month - will offer fresh clues on the path of interest rates.

Traders have ramped up bets on further tightening, with swaps pricing almost 40 basis points of Fed hikes by December, up from about 15 basis points in early June. Economists surveyed by Bloomberg expect both headline and core inflation to have eased slightly in June, though both are forecast to remain well above the Fed’s 2% target.  

Fed Chair Kevin Warsh will also make his first congressional appearance since taking the helm after pledging to scale back forward guidance on the rate outlook.
