Key Takeaways
- Iran has officially rejected a 10-day ceasefire proposal aimed at opening negotiations over the Strait of Hormuz, effectively blocking current diplomatic tracks.

- U.S. 10-Year TIPS yields surged to 2.438% in a $20.8 billion auction, reflecting heightened inflation fears as regional conflict drives oil prices toward $90 per barrel.
- Kuwait’s largest power and water desalination plant was struck by a fire following Iranian attacks, threatening 90% of the nation's drinking water supply.
- The U.S. House of Representatives passed a separate war powers measure (214-208), highlighting a deepening partisan divide over the ongoing military campaign.
Diplomatic Gridlock and Escalating Hostilities
Diplomatic efforts to de-escalate the conflict between the United States and Iran reached a standstill on Thursday. Sources report that Tehran has refused to "improve" or accept a 10-day ceasefire proposal originally intended to facilitate discussions regarding the Strait of Hormuz. This rejection has led U.S. officials to conclude that the diplomatic track is currently blocked, even as U.S. Central Command (CENTCOM) continues its 12th consecutive day of airstrikes against Iranian targets.
The regional fallout has expanded beyond the immediate combatants, with Kuwait reporting a significant fire at its primary power generation and water desalination facility. The Kuwaiti Ministry of Electricity, Water and Renewable Energy confirmed the incident followed Iranian strikes, prompting the activation of emergency plans. This attack on critical infrastructure has raised alarms over water security, as the facility is responsible for nearly 90% of Kuwait's drinking water.
Congressional Divide Over War Powers
In Washington, lawmakers remain sharply divided over the executive branch's authority to continue the war. The U.S. Senate narrowly killed a joint resolution under the War Powers Act in a 47-49 vote, failing to reach the threshold needed to force an end to hostilities. While Senator Susan Collins joined Democrats in support of the measure, the effort was stymied by the absence of other key Republicans and the opposition of Senator John Fetterman (/stock/POLITICS).
Conversely, the House of Representatives successfully passed its own version of the resolution in a 214-208 vote. Led by Representative Pramila Jayapal, the measure saw four Republicans defect from their party to support the withdrawal of U.S. forces. Despite the House victory, the conflicting results in the Senate ensure that President Donald Trump maintains his current military trajectory without immediate legislative restraint.
Market Impact and Inflationary Pressure
Financial markets are reacting to the prolonged instability with increasing volatility. The U.S. Treasury auctioned $20.8 billion in 10-year Treasury Inflation-Protected Securities (TIPS) at a high yield of 2.438%, significantly higher than the previous 2.169%. The bid-to-cover ratio dropped to 2.30, signaling softer demand as investors grapple with real yields reaching their highest levels in nearly two decades.
The surge in TIPS yields is closely tied to energy markets, where WTI Crude has topped $90 per barrel due to the restricted traffic in the Strait of Hormuz. Market analysts suggest that the 94% drop in shipping traffic through the strait is fueling global inflation expectations. In the tech sector, investors are also monitoring Intel (INTC), which is scheduled to report Q2 2026 earnings today amid the broader macroeconomic uncertainty.
