This is good news for Hawaii, where another 90-day exemption from the Jones Act should help keep fuel flowing and prices from spiking.

• Trump extended a waiver of the Jones Act, the law that normally requires goods shipped between U.S. ports to travel on American ships.
• The waiver lets Hawaii bring in fuel and supplies on more types of ships, not just the limited U.S. fleet.
• Hawaii depends heavily on ocean shipping for fuel and daily goods, so more shipping options directly affects prices and supply reliability.
• Congressman Ed Case supports the move, saying Hawaii has already needed the waiver to get fuel delivered from the mainland.

Outlook: As long as the waiver stays in place, Hawaii's fuel supply should stay more secure, but the underlying reliance on the Jones Act's limited shipping options remains a recurring risk every time the waiver comes up for renewal.
