🗞️ Why in News The Philippines became the first country to declare a national energy emergency on March 25, 2026, as fuel supplies run critically low following the effective closure of the Strait of Hormuz after the US-Israel-Iran conflict. Simultaneously, the Persian Gulf is witnessing the largest documented GPS jamming event in maritime history.

Philippines Energy Emergency

President Ferdinand Marcos Jr declared the state of emergency, with Energy Secretary Sharon Garin revealing alarming fuel supply data:

Fuel Type Days of Supply Remaining
Gasoline 53 days
Diesel 46 days
Jet Fuel 39 days
LPG 24 days
Kerosene ~100 days
Average across all fuels ~45 days

Economic Impact

Pump prices have surged nearly 200%:

  • Petrol: above 90 pesos/litre (~$1.50)
  • Diesel: near 130 pesos/litre
  • Kerosene: close to 145 pesos/litre

The government is working to procure 1 million barrels of oil from countries within and outside ASEAN to build buffer stock.

Root Cause — Strait of Hormuz Closure

Following Operation Epic Fury (US-Israel strikes on Iran beginning February 28, 2026), Iran effectively blocked the Strait of Hormuz. The Strait is the only sea connection between the Persian Gulf and the Indian Ocean.

Hormuz — Why It Matters

Parameter Data
Width ~33 km
Navigable lane 3 km each way
Daily crude oil flow (pre-crisis) ~20 million barrels
Share of global traded oil ~20%
Share of global LNG trade ~25-30%
Key exporters via Hormuz Saudi Arabia, Iraq, UAE, Kuwait, Qatar, Iran

Asian countries are especially vulnerable — the Middle East accounts for about 60% of Asia’s oil supply.

GNSS Disruption — Largest GPS Jamming Event in Maritime History

The conflict has produced unprecedented electronic warfare in the maritime domain.

Scale of Disruption

Date Vessels Affected
February 28 (Day 1 of strikes) 1,100+
March 7 1,650+ (55% increase in 2 weeks)

Maritime analytics firm Windward identified at least 30 distinct jamming clusters across the waters of Saudi Arabia, Kuwait, UAE, Qatar, Oman, and Iran.

How GNSS Jamming Works

Jamming involves broadcasting powerful radio signals on the same frequencies as GPS satellites (L1: 1575.42 MHz), drowning out the legitimate satellite signal. Spoofing involves transmitting fake GPS signals that receivers accept as authentic, causing vessels to display incorrect positions.

Impact on Navigation

Spoofed or jammed positions propagate into:

  • ECDIS (Electronic Chart Display and Information Systems)
  • AIS (Automatic Identification System)

This creates false compliance alerts, potential regulatory violations from apparent territorial incursions, and critically impairs collision avoidance in congested waters. By March 7, maritime traffic through the Strait fell to near-zero levels — only three vessel crossings recorded in a single day.

India’s Vulnerability

India is among the most exposed countries:

  • 85-88% crude oil import dependence
  • ~9 million Indians in Gulf countries
  • ~$40 billion annual remittances from the Gulf
  • SPR capacity: only 9.5 days (vs IEA-recommended 90 days)
  • 60-65% of crude imports transit through Hormuz

Lessons for Global Energy Governance

The crisis exposes structural vulnerabilities in global energy architecture:

  1. Chokepoint dependence — Hormuz, Malacca, Suez, Bab el-Mandeb
  2. Inadequate strategic reserves — most Asian nations hold far less than IEA’s 90-day standard
  3. Electronic warfare and maritime security — GPS-dependent navigation is a single point of failure
  4. Transition energy security — renewables reduce oil dependence but LNG (also transiting Hormuz) is a transition fuel
