Americas Chart Pack: May
Introduction
The May 2026 Americas Chart Pack shows US refined product inventories 11,900 mbbl below seasonal norms, locking in the USGC as the world's barrel of last resort. The RBOB/HO spread is narrowing as summer gasoline demand accelerates, diesel is approaching minimum workable levels, and USGC arbs to NWE, MED, WAF, and LATAM remain open. But a US export ban on refined products looms as the summer's defining tail risk.
"US total refined product inventories sit approximately 11,900 mbbl below seasonal norms year-on-year, as the US continues to serve as the global 'barrel of last resort.'"
