In a sudden geopolitical shift that caught markets off guard, the US and Iran have agreed to reopen the Strait of Hormuz to commercial shipping. Dozens of vessels, many of them oil tankers, are now transiting the crucial waterway. Yet British shipping firms remain cautious, and with good reason: the cost of insurance remains elevated, and the memory of seized tankers lingers like a bad debt.
For those of us who track the financial currents, this is a classic case of 'buy the rumour, sell the news'. The price of Brent crude had already priced in a disruption premium of some $5 per barrel over the past fortnight. When the first ships cleared the strait, oil futures dropped 2%. That's the market's way of saying 'we've already paid for this outcome'.
But the real story lies in the risk premiums that have not yet washed away. London underwriters are quoting war risk insurance at double the pre-crisis level. That is a tax on every barrel of oil and every ton of liquefied natural gas that passes through the Gulf. It is a cost that will show up on corporate balance sheets and eventually on household bills.
The British government, ever eager to dip into the public purse, is reportedly considering a subsidy for domestic fuel costs. This would be a mistake. It would reward the very speculative behaviour that amplifies these crises. The proper response is to let prices adjust, let consumers conserve, and let the market allocate scarce resources. That, after all, is the mechanism that has kept the lights on in Britain through far worse shocks.
We should not be fooled by the fleeting relief in the oil markets. The underlying tensions between Tehran and Washington remain as fraught as ever. The US has agreed to unfreeze $6 billion in Iranian assets in exchange for the release of hostages; Iran gets hard currency at a time of crippling inflation. This is a liquidity injection into an economy that funds proxies across the Middle East. It will not end well.
For British tanker operators, the calculus is simple: the headline risk is down, but the tail risk remains. One errant speedboat, one miscalculated drone strike, and the Strait could be slammed shut again. The insurance market, which never forgot the 2019 attacks on Saudi Aramco facilities, is pricing that risk with a hefty margin.
Meanwhile, the Bank of England sits on the sidelines, watching inflation expectations tick up. The bond market, that great oracle of fiscal discipline, is beginning to demand higher yields on gilts. If the government responds to this crisis by borrowing more, it will find investors less accommodating. The era of cheap money is ending; the era of geopolitical risk premiums is just beginning.
The reopening of the Strait of Hormuz is a welcome development for global trade, but it is not a reason for complacency. The market's verdict is clear: we have bought time, not safety. British shipping should navigate with caution, and the Treasury should keep its hands off the fuel subsidy lever. The bottom line, as always, is that there is no free lunch, especially not in the Persian Gulf.
