MarsBit: 10-Day Ceasefire Proposal Emerges, But Risks to Energy, Shipping, and Capital Costs Persist

Huo Xing Finance reports: On July 21, a new diplomatic opening emerged in the U.S.-Iran conflict. Iran confirmed receipt of a proposed “10-day ceasefire” plan from mediators, with Qatar and Pakistan working to restore both sides to their pre-July 9 status in order to resume implementation of the previous memorandum of understanding. However, on the same day, U.S. forces launched their tenth consecutive airstrike on Iranian targets, and Trump publicly stated that if Iran causes further U.S. military casualties, it would pay “many times over,” indicating that military pressure and diplomatic engagement are proceeding simultaneously. Markets should note that such ceasefire proposals are more likely tactical arrangements to buy time for negotiations rather than signals that the conflict is about to end. The core disagreement between the U.S. and Iran remains centered on control of and security for shipping in the Strait of Hormuz. Iran has explicitly identified the Strait of Hormuz as vital to its national security, while the U.S. views restoring commercial shipping as one of the primary justifications for continuing military operations. Until substantive progress is made on this issue, energy supply chains will remain unable to normalize. A larger variable lies in the Red Sea. The Houthi rebels have announced a maritime embargo against Saudi Arabia, and Saudi Arabia has stated it will take necessary military action to secure the Bab el-Mandeb Strait. This means global markets are simultaneously facing risks to two critical energy arteries: the Strait of Hormuz, responsible for exporting Persian Gulf crude oil, and the Bab el-Mandeb Strait, through which approximately 4.9 million barrels per day of Saudi crude pass via the Red Sea. Even if the Houthis ultimately do not fully block these routes, merely the announcement is sufficient to raise insurance costs, alter vessel scheduling, and disrupt shipping expectations. Beyond energy risks, new supply shocks have emerged in the Black Sea. The Kazakh CPC oil terminal has been forced to halt operations after another tanker attack, while Ukrainian and Russian grain exports have also been disrupted simultaneously. This means markets are no longer merely concerned about Middle Eastern crude oil but are now facing a dual supply pressure: “energy + food.” As rising oil prices increase transportation and fertilizer costs, while Black Sea grain exports remain constrained, inflationary pressures in emerging markets and food-import-dependent nations will further intensify. This supply shock is resonating with renewed hawkish discussions within the Federal Reserve. Former New York Fed President Dudley argues that demand expansion driven by AI investment, rising energy prices, and still-easy financial conditions could force the Fed to face greater upward pressure on rates this fall. However, Morgan Stanley maintains its view that interest rates will remain unchanged for the full year, asserting that market-driven financial tightening is equivalent to several rate hikes. What truly matters is not which view prevails, but the Fed’s tolerance for “energy-driven inflation” versus “economic slowdown.” Wall Street capital has already adopted defensive strategies. U.S. money market funds managing over $8 trillion in assets have recently shortened duration, increasing holdings in overnight repos and floating-rate bonds—indicating that large investors are willing to sacrifice some yield in exchange for greater reinvestment flexibility. This reflects preparation for two possible scenarios: if oil prices continue rising, the Fed may be forced to maintain high rates for longer; if tensions suddenly ease, short-term rates could reprice rapidly. For risk assets, the greatest pressure under current conditions does not stem from any single event but from simultaneous unpredictability in policy and supply chains. Any new actual disruption at any of the three critical nodes—the Strait of Hormuz, the Bab el-Mandeb Strait, or the Black Sea—could quickly transmit to oil prices, grain prices, and bond yields; meanwhile, under Powell’s leadership, the Fed has deliberately reduced forward guidance, making it even harder for markets to anticipate policy trajectories. In the short term, markets will focus on three key indicators: whether the 10-day ceasefire proposal receives substantive responses from the U.S. and Iran; whether the Houthis take action against Saudi-associated vessels; and when the CPC terminal will resume loading operations. These three signals will determine whether energy risks remain confined to the “expectation level” or escalate into actual supply shortfalls.
