This week has seen a change in the balance in West Asia, and New Delhi is observing this change in detail. In Saudi Arabia on Friday, King Salman, Crown Prince Mohammed bin Salman, Turkish President Recep Tayyip Erdogan and Pakistani Prime Minister Shahbaz Sharif signed what was dubbed the Makkah Joint Defence Agreement, which contains almost a verbatim copy of Article 5 of the NATO charter: “An attack against one of the Parties is considered an attack against all the Parties.” Its name was quickly attached to the "Islamic NATO," and that is a handy nickname given that the legal framework is more complex, but the idea is right on target. This bloc brings together Saudi financial strength, Turkey's battle-tested and NATO integrated army and Pakistan's nuclear arsenal, the sole nuclear capability in the Muslim world. It is not a symbolic cluster. It's a hard-power triangle that's been fashioned on the backdrop of a region that's still digesting the shock of the war with Iran, missile attacks on Saudi infrastructure and widespread skepticism in the Gulf capitals about the extent to which western security assurances can now be relied upon.

The development is not a theoretical one for India to simply file away. The ministry of external affairs has reacted, with spokesperson Randhir Jaiswal stating that New Delhi is ‘closely following the pact' and separately keeping a check on related security developments in the country involving Pakistan. Remove the diplomatic deference from that word and the anxiety that lurks in the background is hard to miss. Nuclear-armed Pakistan is now part of an official collective defence arrangement with two of the Islamic world's biggest military and economic powers, as India-Turkey ties are frosty because of Ankara's open backing for Islamabad during Operation Sindoor. Riyadh, of course, has still not severed ties with New Delhi and has been careful about how the deal is framed, as the agreement is defensive and not anti-Indian. However, "intent" and "structure" are two different things, and an agreement signed with diplomatic assurances ceases to exist once it has been signed. So far, India's response has been what analysts are calling “strategic patience” strengthen relations with countries in the Gulf not in this new triangle, beef up the relationship with Israel and Washington, and avoid public overreaction and overreach while making the phone calls.

This realignment is overlain by another security challenge, beyond Pakistan's control. The trilateral photo-op in Mecca may have left people with the impression that the border conflict with the Afghan Taliban, that flared again in October last year and turned violent in open combat by February, has been resolved. The United Nations has reported more than 370 Afghan civilian deaths in the first quarter of this year, including the controversial attack on a drug-treatment center in Kabul. Islamabad alleges that Kabul is hiding the Pakistani Taliban in the country, while Kabul alleges that Pakistan is infringing upon Afghan sovereignty and killing civilians. A Pakistan dealing with an insurgency on its western border, supporting a weak economy and now making a commitment for collective-defence with Saudi Arabia and Turkey is a Pakistan trying to do too much at once. This contradiction is seldom settled in an amicable fashion.

Then there is Iran, where the fog has indeed become thicker. Since he took over from his father as supreme leader after the latter was killed in the attack on February 28, which began this war, Mojtaba Khamenei has remained silent in any unscripted setting, according to various reports on various outlets, including IranWire and Israeli media. Rumors of the president's critical condition have reached the highest echelons of the regime, according to one source close to the government of Masoud Pezeshkian, who said the officials would not be surprised when news of the president's death is received soon. All of these are unconfirmed. Iranian officials have come out with a strong response publicly. But all the pattern – months of written statements read by anchors, no video, no audio, no public appearance even at his own father's funeral is enough to make even the most dubious analysts treat the health rumours with respect as opposed to dismissing them as little more than a form of information warfare. Whatever the reality is, Tehran's uncertainty is starting to influence decisions in the real world of Strait of Hormuz business as usual.

This is where geopolitics becomes economics in the case of Hormuz. That 34-kilometre channel carries about 20 million barrels of oil a day, about a fifth of the world's seaborne oil, in normal times. Iran and Oman are working on a framework in which inbound traffic would pass through Iranian-controlled waters and outbound traffic via an Omani lane, but the two sides are far from agreement on tolls, with Tehran demanding 5 to 7 percent of the cargo value, compared with Oman's offer of 3 percent, and Washington insisting on no tolls and no rights to approve the regime, dubbing any toll structure a "dangerous precedent. Brent crude has been rocketing on every single headline this week, ending the week around $83 a barrel following news of an Iran that has tightened its draft transit plan. Here traffic through the strait fell 1% on one day this week than on the previous day. For every 10 per cent increase in oil prices, the IMF estimated, the inflation rate rises by about 0.4 per cent and growth slows by 0.15 per cent which can be a significant number for India, an import-dependent economy.

There's an alliance management subplot going on in Washington, too. In a public standoff at Blair House, Vice President JD Vance has openly lashed out at “manipulation of American opinion to drag this Iran conflict out for as long as possible” by Netanyahu and his government, and the two sides have described their meeting in a measured, carefully-worded way as “just a frank discussion.” All these threads are not independent, the new Islamic bloc, Iran's leadership vacuum, the Hormuz standoff or Washington's Israel friction. Stated together, they point to an area where old assurances are being rewritten in real-time, and where India's calculating, careful, and invariably alert, calculations will only become more significant from this point.
