President Trump's Iran war is having a decisive impact on U.S. inflation, which is used to determine how much Social Security benefits increase from one year to the next.
One independent Social Security and Medicare policy analyst nearly doubled their cost-of-living adjustment (COLA) forecast following the release of the March inflation report.
However, a higher Social Security COLA doesn't necessarily mean beneficiaries are better off.
History-making moments were aplenty for America's leading retirement program, Social Security, in 2025. The average monthly retired-worker benefit surpassed $2,000 for the first time, while Social Security's cost-of-living adjustment (COLA) tipped the scales at 2.8% -- the first time in nearly three decades that Social Security payouts have increased by at least 2.5% for five consecutive years.
Another history-filled year looks to be on tap, but for an entirely different reason. Following the latest inflation update from the Federal Reserve, a big change in Social Security's COLA may await recipients come 2027.

Between the 10th and 15th of every month, the U.S. Bureau of Labor Statistics (BLS) releases the prior month's inflation data, allowing anyone to peruse how prices are changing, compared to the previous year. Although the Fed has been targeting a 2% long-term inflation rate since 2012, trailing 12-month inflation (TTM) has spent the last five years above this mark.
What makes inflation data so noteworthy at the moment is that we're beginning to see the effects of the Iran war showing up in economic data.
At the end of February, Trump gave the green light for U.S. military forces to commence attacks against Iran. Subsequent to these actions, Iran closed the Strait of Hormuz to most commercial shipping vessels, thereby tying up 20 million barrels of petroleum liquids per day (representing 20% of global crude oil demand).
The largest energy supply disruption in modern history has sent crude oil prices soaring and begun pinching consumers at the fuel pump. We've witnessed gas prices rise at their fastest pace in more than 30 years.
⛽ Average U.S. gas prices per gallon on May 6, per AAA:
-- NBC News (@NBCNews) May 6, 2026
• Regular: $4.54 (⬆️ $1.56 since war in Iran began on Feb. 28)
• Premium: $5.39 (⬆️ $1.85 since war began)
• Diesel: $5.67 (⬆️ $1.81 since war began)
Additionally, the inflationary effects of energy supply shocks often lag for businesses by a few months. Once economic data begins to reflect higher transportation and production costs for businesses, the U.S. inflation rate can jump further.
On Monday, May 11, the Federal Reserve Bank of Cleveland's Inflation Nowcasting tool provided its newest inflation forecast for May. Taking into account newly released economic data, the Cleveland Fed's forecasting tool projects that TTM inflation will climb to 3.89% in May.
To put this into perspective, U.S. TTM inflation was just 2.4% in February. The effects of President Trump's Iran war are expected to increase TTM inflation by almost 150 basis points over three months. This is a worrisome pace of acceleration, with potentially significant implications for Social Security payouts in 2027.
Social Security's cost-of-living adjustment is effectively a "raise" passed along each year that accounts for the inflationary pressures beneficiaries face. If the cost of goods and services regularly bought by seniors continued to rise and Social Security benefits remained static, buying power would steadily decline over time. Social Security's COLA attempts to perfectly offset this potential loss of purchasing power.
Since 1975, the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) has served as Social Security's inflation-measuring yardstick.
Even though the CPI-W is reported monthly by the BLS, only TTM readings ending in July, August, and September (i.e., the third quarter) are used to calculate Social Security's COLA. Thus, if these inflationary pressures from the Iran war persist into the third quarter, beneficiaries can expect a larger raise in 2027.
Following the release of the March inflation report, independent Social Security and Medicare policy analyst Mary Johnson nearly doubled her 2027 COLA forecast to 3.2% from 1.7%. While the Consumer Price Index for All Urban Consumers (CPI-U) (the number typically used for inflation-reporting purposes) differs slightly from the CPI-W, the CPI-W's year-over-year increase in May is likely to be similar to the Cleveland Fed's 3.89% inflation forecast.

Hypothetically, if this inflation trajectory were to persist and Social Security's 2027 COLA came in at/around 3.9%, it would mark the fifth-highest year-over-year percentage increase in 35 years!
But don't mistake a historically high cost-of-living adjustment for Social Security beneficiaries being better off. Throughout much of the 21st century, retired-worker beneficiaries have received the short end of the stick -- and that's unlikely to change in 2027.
According to a July 2024-published analysis by nonpartisan senior advocacy group The Senior Citizens League, the purchasing power of Social Security income has declined by 20% for retirees since 2010. This decline in buying power reflects the inherent flaws of the CPI-W.
For example, 87% of Social Security beneficiaries were 62 or older as of December 2024, per Social Security's 2025 Fast Facts and Figures report. Despite aged beneficiaries making up seven out of eight recipients, the CPI-W is tracking pricing pressures for "urban wage earners and clerical workers." These are individuals who are typically under age 62 and not receiving a Social Security retired-worker benefit. Put another way, the costs that matter most to seniors aren't being accurately reflected in the inflationary index that determines the annual COLA.
Additionally, Medicare's monthly Part B premium has been consistently offsetting Social Security COLAs. Part B is the segment of traditional Medicare that's responsible for outpatient services.
This year, the standard Part B premium jumped 9.7%, or $17.90 per month, to $202.90. Annual increases ranging from 6% to 16% have been common for most of the century, and they can mostly or fully offset Social Security's COLA for lifetime low-income beneficiaries.
Although the Social Security's 2027 COLA could be a history-maker, it's not going to reverse a quarter-century of structural issues with the CPI-W or offset a breathtaking climb in the Medicare Part B premium.

Four leading AI models discuss this article
"The projected 2027 COLA increase is a lagging indicator that will be immediately neutralized by rising Medicare Part B premiums and persistent energy-driven cost-of-living increases."
The article's premise relies on a specific geopolitical scenario—an ongoing Iran war—that is already priced into energy futures. While the Cleveland Fed’s 3.89% inflation projection suggests a higher 2027 COLA, the real story is the erosion of real purchasing power via the CPI-W mismatch. Investors should focus on the 'hidden' tax of rising Medicare Part B premiums, which act as a drag on consumer discretionary spending for the 65+ demographic. If energy prices stabilize, the inflationary shock will prove transitory, rendering the 2027 COLA projections overly aggressive. The structural deficit in Social Security remains the primary, long-term systemic risk, not the temporary volatility in energy-driven CPI-W adjustments.
If the Strait of Hormuz closure persists, energy-driven inflation could trigger a wage-price spiral that forces the Fed to keep rates higher for longer, crushing equity valuations regardless of COLA adjustments.

"A historically high 2027 COLA driven by transient energy inflation will be largely or entirely offset by Medicare Part B premium increases, leaving retirees with flat or negative real purchasing power gains."
The article conflates two separate issues: a near-term inflation spike (real, energy-driven, likely temporary) with a structural COLA forecast for 2027 (speculative). The Cleveland Fed's 3.89% TTM projection is a single-month nowcast, not a Q3 average — the actual metric that matters for COLA. Energy shocks typically fade within 6-9 months; crude has already retreated from February peaks. The article assumes persistence through July-September 2027, which is a heroic assumption. Meanwhile, the CPI-W vs. beneficiary-basket mismatch is valid but not new — this has been true for decades. The real risk: if inflation normalizes by Q3 2027, beneficiaries get a modest 2-2.5% COLA while Medicare Part B premiums likely rise 6-8%, leaving them worse off in real terms.
If the Iran conflict escalates further or geopolitical fragmentation persists, energy costs could remain elevated through 2027, making the 3.9% COLA forecast less speculative than dismissing it. Additionally, wage-price spiral dynamics from tight labor markets could sustain inflation beyond the initial energy shock.
"Headline 2027 COLA could be higher, but net real benefits for retirees are likely limited by Medicare premium growth and the true inflation path, not just a one-off spike."
The article ties a war-driven energy shock to a potentially higher 2027 Social Security COLA, which is plausible but not guaranteed. Inflation persistence depends on energy prices, policy actions, and the timing of CPI-W data. Remember, COLA is calculated from CPI-W averages (Jul-Sep) and applied the following year, while seniors face offsetting Medicare Part B premium increases that can erode real gains. A softer inflation path or cooling energy costs could push 2027 COLA back toward 2–3%, even if near-term signals look hot. The missing nuance is how much of the rise is transitory versus structural and how the broader policy mix interacts with seniors’ actual cost baskets.
If energy prices remain elevated or energy shocks persist, a higher COLA could materialize; but the article leans too heavily on a single inflation narrative without quantifying the confidence interval or the odds of a quick reversion.
"Higher COLAs funded by deficit spending create a pro-cyclical inflationary feedback loop that forces the Fed to maintain higher rates for longer."
Claude, you correctly identified the CPI-W/Medicare premium squeeze, but both you and Gemini are glossing over the fiscal multiplier effect. If the 2027 COLA lands near 4% due to energy-driven inflation, the Treasury must fund that payout via higher deficit spending. This creates a feedback loop: more deficit-driven liquidity sustains the very inflation the Fed is trying to crush. We aren't just looking at a purchasing power mismatch; we are looking at a pro-cyclical fiscal policy error.

"Higher COLA doesn't automatically trigger deficit spending; the real risk is whether persistent energy inflation forces the Fed into a rate-growth tradeoff."
Gemini's fiscal multiplier argument assumes the Treasury *must* fund higher COLA via deficit spending—but that's not automatic. COLA is an obligation, yes, but it's pre-funded through payroll taxes and trust fund drawdowns. The real squeeze is trust fund depletion accelerating, not immediate deficit monetization. That said, if energy inflation persists AND wage growth stays elevated, the Fed faces a genuine policy bind: raising rates kills equities and housing, but holding steady risks wage-price spiral. The article doesn't quantify how likely that bind actually is.
"COLA increases tied to energy shocks risk trust fund depletion and policy fixes, not automatic deficit monetization."
Gemini’s 'fiscal multiplier' claim assumes higher COLA automatically bleeds into bigger deficits. In reality, Social Security is funded via dedicated payroll taxes and trust fund reserves, with any COLA-induced shortfall typically addressed by legislative tinkering (tax tweaks, reserves, or benefit tweaks) rather than instant Treasury monetization. The real risk is trust fund depletion accelerating under higher benefits, forcing policy tweaks that could surprise markets. The linkage to broad liquidity via deficits is overstated.
Panelists generally agree that energy-driven inflation may temporarily boost the 2027 COLA but caution that this could be offset by rising Medicare Part B premiums, potentially leaving seniors worse off in real terms. They also highlight the risk of trust fund depletion accelerating under higher benefits, which may require policy tweaks.
