A new defense pact between Saudi Arabia, Turkey, and Pakistan could rattle NATO and send oil prices sharply higher — bad news for drivers, the middle class, and stocks.

• Saudi Arabia, Turkey, and Pakistan signed the Mecca Agreement on August 7th, a mutual defense pact where an attack on one is treated as an attack on all three.
• The danger is Turkey: it's a key NATO member, so a clash with Israel could drag NATO and the U.S. into a crisis over how to respond.
• A wider Middle East conflict would spike oil and gas prices, squeezing household budgets already stretched thin.
• The pact is seen as fallout from the failed effort to weaken Iran, pushing these countries to build their own security bloc away from U.S. protection.
• More such regional alliances are expected, part of a broader splintering that also threatens Europe's unity and the euro.

Outlook: No immediate war is expected, but rising tensions in the region could keep oil and fuel prices elevated and pressure markets in the months ahead.
