Social Security's Trump Bump-Led 2027 COLA Is Doing Something That Hasn't Been Witnessed This Century

For a majority of retirees, Social Security represents more than just a monthly check. The income Social Security's roughly 55 million retired-worker beneficiaries receive monthly is often vital to making ends meet.

Given how important Social Security income is to the financial well-being of our nation's aging workforce, few announcements are more anticipated than the annual cost-of-living adjustment (COLA) reveal in October. Social Security's COLA is essentially the near-annual "raise" passed on to recipients that accounts for the inflation (rising prices) they've faced. If benefits didn't adjust for inflation, retirees' buying power would decline over time.

Social Security's 2027 COLA is particularly unique, courtesy of President Donald Trump. A couple of the president's policies are directly influencing consumer prices and, therefore, impacting Social Security's raise. This Trump bump-led 2027 COLA will do something that hasn't been witnessed in the 21st century.

This hasn't happened in three decades

Since the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) became Social Security's inflation-measuring yardstick in 1975, there have only been three years during which prices declined (deflation): 2010, 2011, and 2016. In other words, modestly rising prices are a common occurrence, which means beneficiaries are accustomed to receiving a benefit bump almost every year.

However, the prevailing inflation rate in 2026 is well above the norm, leading the Social Security Administration to announce a 3.6% cost-of-living adjustment on Oct. 14. This ties for the fifth-largest annual raise since 1993, surpassed only by COLAs of 4.1% (2006), 5.8% (2009), 5.9% (2022), and 8.7% (2023).

Two of President Trump's policies are the fuel responsible for lifting annualized inflation to a three-year high of 4.2% in May.

The president's tariff and trade policy is the first driver of above-average inflation. Trump unveiled his "Liberation Day" tariffs in April 2025, implementing sweeping global duties and higher reciprocal tariffs on dozens of countries deemed to have unfavorable trade deficits with the U.S. Even though these tariffs were invalidated by the U.S. Supreme Court in February 2026, the Trump administration used a different justification to reimpose sweeping tariffs in July.

New from the New York Fed: "By February 2026, tariffs had contributed 2.9 pp to goods price inflation, and without them goods prices would have fallen slightly." About one quarter of every point in higher tariff rates shows up in consumer prices within one year. • A 10% across-the-board tariff yields a 2.6% rise in consumer goods prices after one year. • About two thirds of the increase comes from pricier imports, which get passed through quickly. • Another third comes from U.S. made goods, as producers face higher input costs and less import competition. This takes longer, about 6-12 months, to filter through.

According to a new report from three New York Federal Reserve economists writing for Liberty Street Economics ("How Fast Do Tariffs Pass Through into Consumer Prices"), Trump's tariffs are estimated to have increased goods price inflation by 2.9 percentage points by February 2026. Without tariffs, the authors estimate that goods prices would have declined.

The second policy influencing consumer prices is the Trump-led Iran war. Shortly after military operations commenced on Feb. 28, Iran closed the Strait of Hormuz to most commercial vessels. This sparked the largest energy supply disruption in modern history, sending gas and diesel prices to the heavens and providing a tangible boost to Social Security's 2027 COLA.

But it's not just Social Security's outsize COLA for 2027 that makes this increase special. It's that beneficiaries will receive an above-average raise for a sixth year in a row, which is unique.

Since 2022, Social Security's annual raises have clocked in at 5.9% (2022), 8.7% (2023), 3.2% (2024), 2.5% (2025), 2.8% (2026), and the announced 3.6% (2027). You'd have to go back to the 20th century (1988-1997) to find the last time Social Security benefits increased by at least 2.5% for six consecutive years.

But wait -- there's more

While a first-of-this-century Social Security COLA is absolutely headline-worthy, it isn't the only history-making moment that looks to be on deck. For Social Security retirees who are also enrolled in traditional/original Medicare, a first-in-four-year silver lining likely awaits.

Though Social Security's annual cost-of-living adjustment is designed to keep pace with inflation, the CPI-W has its flaws. For example, it tracks the cost pressures faced by "urban wage earners and clerical workers," who are typically under the age of 62 and not currently collecting a Social Security benefit. In short, the CPI-W isn't necessarily tracking the costs that matter to the majority of its beneficiaries -- including rising Medicare expenses.

Original Medicare has three components:

• Part A: Inpatient hospital care
• Part B: Outpatient services
• Part D: Prescription drugs

Whereas Part A has no monthly premium for about 99% of workers, Parts B and D have standard monthly premiums. Part B's standard monthly premium is $202.90 in 2026, and it's usually deducted from a retiree's Social Security check.

72 million Social Security beneficiaries will see a 3.6% cost-of-living adjustment (COLA) beginning in January 2027. The 26% increase in benefits over the past 5 years is the biggest 5-year increase since 1982-1986. https://t.co/jMp13XUziC

Throughout most of this century, Part B premiums have been climbing at a considerably faster rate than Social Security's COLA. The aforementioned annual raises of 3.2%, 2.5%, and 2.8% between 2024 and 2026 were accompanied by respective Medicare Part B premium hikes of 5.9% (2024), 5.9% (2025), and 9.7% (2026). When the Part B premium rises considerably faster than Social Security's COLA, it can gobble up most or all of the upcoming year's raise.

But according to the 2026 Medicare Trustees Report, the Part B premium is estimated to rise by only 3.25% to $209.50 per month in 2027. If this estimate (keyword!) proves accurate, it would mark the first time since 2023 that Social Security's COLA is climbing at a faster rate than Part B.

For tens of millions of retirees, this dynamic should enable them to hang onto more of next year's raise, which is worth celebrating.
