Market Brief, 13 July 2026: Gulf Escalation Reignites the War Trade as Oil Spikes and Yields Surge on Inflation Fears

The session of Monday 13 July 2026 opens on a geopolitical shock that reshuffles everything. A direct military escalation between the United States and Iran has swept away the fragile optimism of the June truce and reignited the war trade across every asset class. Oil spikes, bond yields surge on inflation fears, the dollar reclaims its status as the ultimate safe haven, and Asian technology suffers a severe rout. In the background, a structural shift in capital flows is taking shape in Japan.

1. The geopolitical trigger: escalation in the Gulf

The dominant narrative across markets this Monday is the intensifying conflict between the United States and Iran. Over the weekend, the United States launched fresh missile strikes targeting Iranian infrastructure, aiming to degrade Tehran’s ability to attack international shipping. In retaliation, Iran launched counter-strikes against US allies. The situation is further muddied by conflicting official statements. Tehran claims the Strait of Hormuz is closed, while US Central Command insists shipping continues through the southern route. This confusion has shattered the fragile optimism of a ceasefire, with former President Trump explicitly declaring the truce over and rejecting the notion of continued talks.

2. Energy: the war trade returns

The immediate casualty of this escalation is energy prices. Brent crude futures surged roughly 4 to 5 percent, approaching the 80 dollar per barrel mark. While a steady, albeit clandestine, stream of ships continues to transit the strait, the observable flow remains severely constricted, roughly 20 ships in the past 24 hours compared with a pre-war average of 100 per day. Investors are now pivoting away from pricing in a rapid resolution and instead bracing for a prolonged period of low-level attrition, which threatens to keep supply tight and prices elevated for the foreseeable future.

3. Fixed income: yields spike on inflation bets

Sovereign bonds are bearing the brunt of the inflation scare. US Treasury yields surged across the curve, with the rate-sensitive 2-year note climbing to 4.23 percent, its highest level since February 2025. The 10-year yield rose to 4.58 percent. This selloff is driven by growing market conviction that the Federal Reserve will be forced to respond to higher energy costs. Swap markets now price in nearly 40 basis points of rate hikes by December, a significant leap from just 15 basis points in early June. The upcoming US Consumer Price Index and Fed Chair Kevin Warsh’s congressional testimony are viewed as critical catalysts that could solidify bets on a September rate hike.

4. Foreign exchange: dollar dominance and yen intervention

The US dollar has reasserted its role as the ultimate safe haven, strengthening against all G10 peers. The Bloomberg dollar index rose, with the greenback pushing USD/JPY above the 162 threshold and driving EUR/USD below 1.14. The pound remained subdued below 1.34. In a surprising policy shift, Japan’s finance minister announced measures to force the nation’s massive public pension fund, the 1.6 trillion dollar GPIF, to allocate more capital domestically. This move is aimed at arresting the relentless rise in Japanese government bond yields, which had outpaced even German bunds, and halting the yen’s record weakness. Analysts view this as a potential watershed moment that could reshape global capital flows and reinforce a broader trend of de-globalization that may eventually put downward pressure on US assets.

5. Equities: Asia bleeds, but global futures show resilience

Asian equities suffered a severe rout, led by the technology sector. South Korea’s Kospi tumbled over 8 percent, triggering a circuit breaker that, unusually, failed to mark an intraday low until Taiwan Semiconductor Manufacturing Company reported stellar June sales, helping to trim losses. SK Hynix shares plunged 13 percent in Seoul, with traders citing profit-taking following the firm’s US ADR debut. The Nikkei fell approximately 2 percent. However, a notable divergence has emerged: global equity futures outside the Nasdaq remain relatively resilient, with declines mostly under 1 percent. This suggests a decoupling, where aggregate tech valuations are not yet egregiously overextended, though specific pockets of exuberance remain.

6. Commodities: gold, silver and the fertilizer threat

Precious metals are under heavy pressure. Gold dropped toward 4,060 dollars per ounce, while silver fell nearly 3 percent. The primary driver is the surge in US real yields, which have risen to their highest level since April 2025, a level that historically correlates with gold prices closer to 3,000 than 4,000 dollars. Beyond traditional commodities, a critical hidden risk is emerging in the fertilizer market. The Strait of Hormuz is a vital conduit for urea. While prices have not yet returned to the peaks of 2022, thanks to stable natural gas prices, supply disruptions are hitting farmers just ahead of application season. Combined with the threat of El Niño reducing crop yields, this could lead to stubborn food inflation, a political headache that central banks are largely powerless to address.

7. Corporate and political developments

On the corporate front, Nippon Paint confirmed a 7.5 billion euro bid to acquire Akzo Nobel’s decorative paints business. Politically, the United Kingdom’s presumptive next prime minister, Andy Burnham, is weighing a bolstered budget featuring a land tax and public utility control, while Marine Le Pen has extended her lead in French presidential polls after a court ruling cleared her to run. Meanwhile, the growing rift between Saudi Arabia and the UAE is prompting contingency planning among Gulf executives.

The week ahead

As the dust settles on this volatile Monday, investors face a critical week ahead. The US earnings season will test whether corporate profits can justify the AI-fueled rally. Simultaneously, US inflation data and Fed Chair Warsh’s testimony will determine whether the narrative of higher-for-longer inflation becomes permanent. With central bank speakers also scheduled, including the ECB’s Isabel Schnabel and the BOE’s Huw Pill, markets are walking a tightrope between geopolitical risk, monetary tightening, and economic resilience.
