The atmosphere of international finance changes when oil begins to approach $120 per barrel. It’s more akin to the general tension in a room when someone discreetly brings up a number that everyone was hoping not to hear aloud than panic. After carefully planning a soft landing for the majority of 2024 and 2025, central banks now find that their instruments are pointing in the wrong direction.
The Strait of Hormuz is a single, catastrophic choke point that is responsible for the current spike in crude prices. Shipping through the waterway, which transports about one-fifth of the world’s oil, gas, and liquefied natural gas, came to a complete stop after Iran threatened to shoot at passing ships. It wasn’t subtle what came next. Brent crude futures continued to move, rising toward $93.

In a research note that carried the weight of a warning, Barclays stated that if hostilities continue for a few more weeks, the $120 level is completely attainable. Before the end of the month, their tail scenario, or the unsettling 10% possibility, places Brent at $150.
Pausing on that number is worthwhile. Each barrel costs $150. The last time something similar occurred, entire continents’ energy policies were altered.
Almost immediately, bond markets began to tremble. The yield on 10-year US Treasury bonds increased by more than seven basis points during Asian trading on an exceptionally heavy Monday, marking the biggest single-day increase since January 2026.
The three-year yield for Australia reached its highest level since 2011. Futures on German government bonds fell to levels not seen in fifteen years. Japan’s 10-year yield saw a sharp increase of about 11.5 basis points. These are not tiny motions. This is like raising your voice in a quiet library in the world of sovereign debt.
Stagflation, that ugly term from the 1970s that economists spent decades hoping they would never have to use seriously again, is the fear that runs through all of this. The situation is simple and dire: growth is stifled, oil prices rise, inflation reappears, and central banks are compelled to maintain or even raise interest rates.
According to estimates from the International Monetary Fund, a 10% steady increase in energy prices can reduce economic growth by up to 0.2 percentage points while increasing global inflation by about 0.4 percentage points. The math is not helping anyone, as prices have increased by 80% since the start of the conflict.
Asia was especially uncomfortable because of Morgan Stanley analysts. A persistent $10 increase in oil prices could directly cost Asian economies 20 to 30 basis points of GDP growth, according to a research note. Asia’s oil and gas expenditures would account for 6.3% of the region’s GDP at $120 per barrel. It’s not a rounding error. Oversea-Chinese Banking Corp.
analyst Sim Moh Siong put it succinctly: a one-week halt to Hormuz shipments sets off an intensifying energy shock that drives up prices, strengthens the dollar, raises global yields, and upends the trading consensus that markets had built their 2026 strategies around.
By late Q3 or Q4, central banks in the Philippines, Indonesia, India, and South Korea are now being discreetly discussed as possible rate hikers rather than cutters. In an area that had been holding its breath for financial relief, that is an incredible change.
Not that the Federal Reserve is in a much better position. From July to September, investors’ expectations for the first rate cut have decreased, and some traders no longer anticipate a cut this year. It’s difficult not to notice that the carefully crafted narrative of “easing inflation, gradual recovery” is eroding as you watch this play out.
Production shutdowns have already appeared in Kuwait and Iraq, according to Barclays, and they may eventually spread to the United Arab Emirates and Saudi Arabia. Currently, tankers carrying an estimated 85 million barrels of oil are stuck in the Middle East Gulf, unable to move.
An additional piece of information from Bloomberg Intelligence that offers little consolation is that oil demand usually begins to decline around $133 per barrel, indicating that markets have not yet reached the natural ceiling. A lot of economic harm is done covertly between $120 and $133.
The bond selloffs, the updated rate-cut timelines, and the meticulously worded research notes all give the impression that the global financial establishment is facing a situation that it had anticipated but hoped would remain theoretical. Every institution that fought inflation for three years before changing course to support growth must pause and consider which issue it is truly resolving when oil reaches $120.
The solution is not immediately apparent. And for those in charge of international monetary policy, this uncertainty is more unsettling than any particular piece of information.
