Gas Price Spike Threatens Holiday Supply Chains

Executive Signal Summary

Modern Retail's Supply Chain Weekly newsletter reports on rising gasoline prices, driven by drone attacks on Saudi Arabia's oil pipeline and the Iran War, which could squeeze holiday supply chains. While most holiday inventory has already arrived in the U.S., carriers like UPS and FedEx are imposing high fuel surcharges (FedEx at 32.25%). The bigger risk is to consumer demand, as higher gas prices may reduce holiday budgets and shift shopping online. Retailers may increase promotions to counter softer demand. The newsletter also covers peak season surcharges from FedEx, UPS, and USPS, including USPS's new dimensional weight calculation and its transportation surcharge through January 2027. It highlights advice from logistics experts on negotiating surcharges and using multiple carriers. The issue also includes separate articles on Beyond Yoga's pop-up and The Laundress's Target expansion.

California Law Penalizes Robotaxis Blocking First Responders

California Governor Gavin Newsom signed Senate Bill 1246, establishing new regulations for autonomous vehicles (AVs) to improve safety and response times when robotaxis impede traffic or interfere with emergency responders. Companies like Tesla, Waymo, and Zoox must provide on-ground support to first responders and face penalties for blocking them for more than 30 minutes. The law also mandates that remote drivers be based in the U.S. and hold U.S. driver's licenses, and requires notification to local jurisdictions during system-wide failures. The legislation, effective July 2028, follows incidents where robotaxis disrupted emergency operations. Additionally, the newsletter reports various deals and news: Harbinger received $300M from FedEx, HyperGuest raised $25M, REGENT Craft extended its U.S. Marine Corps contract, Quartermaster raised $140M, Voltaback raised €2.8M, Aurora plans 30,000 autonomous trucks by 2030, BMW unveiled an EV cheaper than gas, DoorDash launched drone delivery, Kodiak partnered with Ikea, Lyft settled a lawsuit, and Tesla secured $30B in credit lines.
