The price sign at gas stations is the fastest way for ordinary Americans to understand inflation.

In March, the average retail gasoline price in the United States exceeded $4 per gallon for the first time in nearly four years. Not because of OPEC production cuts, not because of declining shale oil output, but because of a war. A war fought in the Persian Gulf, more than ten thousand kilometers away from the U.S. mainland.

The recent breakdown in negotiations means we will continue to bear the impact of the war, such as the possibility that interest rates may not be cut this year.

Could a War Push Inflation Back to 2022 Levels?

On February 28, the United States and Israel jointly launched a military strike against Iran. This is a timeline that redefines the trajectory of the U.S. economy in 2026.

Brent crude oil surged from about $70 per barrel before the conflict erupted to $118 per barrel by the end of March. Although oil prices have since retreated, they remain high at around $96 per barrel recently. The more than 50% increase in oil prices is tied to a crucial waterway: the Strait of Hormuz.

Iran has effectively blockaded shipping traffic through the Strait of Hormuz, which transports about one-fifth of the world's oil supply. Reports indicate that even during negotiations, the blockade largely remained in place.

This is not just an oil price issue. The gasoline price index accounted for almost three-quarters of the increase in all items in the monthly CPI, with a month-on-month surge of 21.2% and a year-on-year increase of 18.9%. Every refueling, every bill, punishes ordinary American families in specific and detailed ways. Starting last week, the average retail gasoline price in the U.S. exceeded $4 per gallon for the first time in nearly four years.

The energy shock is also spreading throughout the entire economy.

Rising diesel prices are pushing up food transportation costs; fertilizers, another key export commodity shipped through the Strait of Hormuz, face supply disruptions that could increase costs for farmers and consumers. CPI data show food prices rose 2.7% year-on-year.

It's not just food. Amazon will impose a 3.5% fuel and logistics surcharge on third-party sellers in the U.S. and Canada, while delivery companies like UPS and FedEx have also raised fuel surcharges since the Iran conflict began. The tentacles of inflation are reaching into every corner.

Based on the correlation between year-on-year oil price changes and U.S. CPI inflation rates from 2020 to 2025, if Brent crude prices remain between $85 and $100 per barrel throughout 2026, the year-on-year increase in oil prices could reach 30% to 50%, potentially raising the U.S. CPI inflation rate by 1 to 2 percentage points.

And this is just the beginning. Even if a ceasefire holds, considering the damage to energy infrastructure and supply chain disruptions that are difficult to repair quickly, oil prices, although down from their peak, may remain above pre-conflict levels in the medium term, potentially boosting the year-on-year CPI for several months.

Ryan, an economist at Capital Economics, stated that some inflationary effects from energy prices may take months to filter through supply chains to the consumer end, with an impact that "could be very broad."

A war pushed U.S. inflation from 2.4% in February directly back to 3.3% in March, meaning the month-on-month CPI increase was 0.9%, the "largest single-month increase since June 2022."

The Door to Rate Cuts is Half Shut

Before the war, the market assumed the Trump administration had a carefully crafted political script:

On January 30, 2026, Trump formally nominated former Federal Reserve Governor Kevin Warsh as the next Fed Chair. Powell's era came to an end. The market quickly began pricing in: a new chairman taking office, a clear path to rate cuts. After Warsh's nomination, most market futures traders expected two rate cuts this year.

There was a fairly clear political interpretation of this personnel arrangement. Wilkes, Director of U.S. Economic Research at Bloomberg Economics, stated that whoever ultimately gets nominated will face external skepticism upon taking office, with people believing he must have promised to carry out the U.S. President's directives at the Fed, the first and most important being to aggressively push for a significant cut in the federal funds rate regardless of inflationary consequences.

Therefore, in almost all economic analyses and macro forecasts at the beginning of the year, the actual pace of Fed monetary policy easing in 2026 was expected to be faster than market expectations, with 2 to 3 rate cuts totaling 50 to 75 basis points for the year.

But after the war, the data changed dramatically.

Polymarket currently gives a 44% probability of zero rate cuts for the entire year of 2026. Before the war erupted, the probability of zero cuts this year was only 4%. But since the war began, the probability of no rate cuts this year has been rising steadily, and from the end of March onwards, the probability of zero cuts has consistently been the highest forecast on that market. Additionally, the probability of a single 25-basis-point cut is currently 26%. Another prediction platform, Kalshi, sets the probability of a zero-cut scenario at 38.5%. The trading volumes on these platforms reflect real money bets.

The recently released minutes of the Fed's FOMC meeting on March 17-18 showed that most officials were concerned the war could harm the labor market, necessitating rate cuts; simultaneously, many policymakers emphasized inflation risks, which might ultimately require rate hikes. The Fed kept rates unchanged in the 3.5% to 3.75% range at its March meeting.

One set of minutes contained the possibility of both rate cuts and hikes. This might be one of the most awkward situations in Fed history.

Persistently strong inflation has led some economists to believe the Fed will not cut rates this year. Federal funds rate futures pricing indicates a probability of over 70% for rates remaining unchanged within the year.

Chris Zaccarelli of Northlight Asset Management pointed out that the duration of the war and the situation in the Strait of Hormuz are crucial. If the supply shock is temporary, the economy can withstand it, and the Fed has a chance to cut rates within the year. But if the inflation shock is more persistent, they may have to hold steady all year.

Gregory Daco, Chief Economist at EY-Parthenon, cautiously predicted that looking ahead to the fourth quarter and year-end of 2026, there might be factors prompting the Fed to ease monetary policy, but that would be for the wrong reasons. He also raised a realistic possibility: the Fed's next move could be a rate hike.

This is no longer a question of "rate cuts being a few months late." This is a policy crisis where the script has been completely disrupted.

The Republican Party's Situation is Quite Grim

Trump's governing logic has always been highly pragmatic. Rate cuts are never just monetary policy; they are a pillar of Trump's political agenda.

The reasoning is simple. Rate cuts lower borrowing costs, stimulate consumption, push up the stock market, and make ordinary people feel that money is easier to earn. And this feeling is reflected in votes. With the reality of midterm elections at the end of the year, as of the time of writing, Polymarket data shows the probability of Democrats winning the House of Representatives is as high as 86%, and the probability of winning the Senate has reversed from a disadvantaged 36% before the war to a leading 56%.

The Republican Party's situation is already quite severe.

The problem is that the political fundamentals of the midterm elections are largely locked in by June. From now on, the time window is running out.

To focus on preparing for the upcoming midterm elections, Trump needs to quickly achieve de-escalation of the conflict to stabilize capital markets and secure political achievements.

Otherwise, the inflation caused by rising oil costs will eventually become clearly evident in the U.S. economy and in American consumers' spending, which would be a blow to Trump's midterm elections and his popular support.

This is precisely why Trump is so eager to seek negotiations with Iran.

Iran Uses Delaying Tactics

And Iran sees this clearly.

Negotiations that began in Islamabad on April 10 broke down just two days later. On April 12, U.S. Vice President Vance announced in Islamabad that the talks had broken down over Iran's nuclear weapons issue, and the U.S. delegation left Pakistan to return to Washington.

The failure of the talks was no accident.

The gap in conditions was on the table even before the talks began. According to analysis, U.S. demands include: Iran must unconditionally open the Strait of Hormuz, must stop all nuclear activities, the quantity and variety of Iranian missiles must be restricted (with no missiles capable of reaching Israel in the future), and must cut off all ties with proxy groups. Iran's conditions for the U.S. were equally high: demanding the complete withdrawal of all U.S. troops from the entire Middle East, the cessation of all U.S. and Israeli military actions in the Middle East, the lifting of all economic sanctions imposed on Iran over the past 47 years, and war reparations from the U.S. to Iran.

These are not two close proposals. These are demands from two parallel universes.

Some U.S. think tanks believe Iran may choose a "protracted game," using the midterm elections as a "pressure point" against the U.S.

Understanding this requires understanding a fundamental asymmetry between the U.S. and Iran: Trump has a term limit; Iran does not. As an authoritarian state, the Islamic Republic has existed for nearly half a century, with no pressure from electoral changes. Iran does not need to accomplish anything by the end of 2026. It only needs to wait. Wait for Trump's midterm election window to close, wait for the Republican Party to feel pressure in the House, wait for the political cost in Washington to become high enough, wait for the U.S. to find its own reason to back down.

If Trump continues the war effort and sends ground troops into Iran, it means the U.S. is once again entangled in this war, potentially getting bogged down long-term with Iran. This does not align with U.S. national security strategy and would also impact many of Trump's own domestic and foreign policy agendas.

Trump himself acknowledged the difficulties in the negotiations. He stated that the negotiations were going well, with agreement reached on most issues, but the one truly important point—the nuclear issue—was not settled. The nuclear issue is precisely the bottom line Iran will not concede in the short term.

The entire situation now is this: Trump holds the demands for rate cuts, the pressure of midterm elections, and the military burden of war with Iran, all pressing on a clock that is accelerating towards November. Iran doesn't need to win. It only needs to hold on, to let these negotiations continue to drag out.
