Greg Fleming, President and Chief Executive Officer of Rockefeller Capital Management, said the rapidly growing U.S. national debt poses a greater long-term threat to the American economy than inflation, while arguing that artificial intelligence could ultimately help reduce inflation by boosting productivity. His remarks were published by Bloomberg on Tuesday, July 14, from an interview recorded on May 13, 2026.

Fleming’s comments come as government inflation reports have begun showing signs of easing price pressures, shifting attention back toward Washington’s mounting fiscal challenges.

A Veteran Wall Street Voice

Fleming has spent decades leading some of the nation’s largest financial institutions.

Before becoming the founding President and CEO of Rockefeller Capital Management in 2017, he served as President and Chief Operating Officer of Merrill Lynch and previously led Morgan Stanley’s investment management and wealth management businesses.

He also serves on the board of directors of BlackRock and teaches ethics and financial markets at Yale Law School.

In October 2025, Rockefeller Capital completed a recapitalization that valued the firm at approximately $6.6 billion.

The Numbers Behind the Concern

The United States now carries approximately $39.4 trillion in national debt.

During the first nine months of Fiscal Year 2026, the federal government recorded nearly $1.4 trillion in budget deficits—already exceeding the same period a year earlier.

That equates to roughly:

• $155 billion in new borrowing each month.
• Nearly $39 billion in additional debt every week.

Interest payments alone have become one of the federal government’s fastest-growing expenses.

According to the Congressional Budget Office (CBO), net interest on the national debt is projected to total approximately $857 billion during Fiscal Year 2026.

Interest costs reached approximately $970 billion during Fiscal Year 2025 and are projected to climb to roughly $2.1 trillion annually by 2036, totaling $16.2 trillion over the next decade.

The CBO projects interest expenses will equal approximately 3.2% of Gross Domestic Product this year—the highest level on record.

Net interest now exceeds annual federal spending on either Medicare or Medicaid, trailing only Social Security among the government’s largest expenditures.

Not Just Wall Street

Fleming is far from alone in expressing concern.

Maya MacGuineas, President of the Committee for a Responsible Federal Budget, recently warned that federal borrowing could exceed $2 trillion during the current fiscal year despite continued economic growth and relatively low unemployment.

She also noted that both the Social Security and Medicare trust funds are projected to face depletion within the next several years absent congressional action.

Meanwhile, the Congressional Budget Office projects federal debt held by the public will climb to approximately 120% of GDP by 2036.

The Bipartisan Policy Center estimates the United States could once again reach its statutory debt limit sometime between late winter and mid-summer of 2027, depending upon federal revenues and spending.

Why the Timing Matters

Fleming’s warning arrives just as inflation data have begun improving.

This week, the Producer Price Index declined 0.3% in June while the Consumer Price Index fell 0.4%, easing concerns that inflation was accelerating.

Federal Reserve Chairman Kevin Warsh told Congress the latest reports represent encouraging progress but cautioned policymakers against assuming inflation has been permanently defeated.

For Fleming, that distinction is critical.

Inflation tends to rise and fall with economic cycles, energy markets and geopolitical events.

Federal debt, however, continues to grow regardless of monthly inflation reports.

Earlier this year, several Treasury auctions attracted weaker-than-usual investor demand, increasing attention on how financial markets will absorb continued large-scale federal borrowing.

What It Means for Main Street

Growing federal interest costs eventually affect households and businesses alike.

As Treasury borrowing expands, upward pressure on long-term interest rates can increase mortgage costs, commercial real estate financing expenses and borrowing costs for small businesses.

Fleming has repeatedly argued that investors should pay closer attention to federal deficits than short-term inflation data.

At the same time, he remains optimistic that advances in artificial intelligence could improve productivity enough to help moderate future inflation.

Whether those productivity gains arrive quickly enough to offset a national debt approaching $40 trillion remains one of the central economic questions facing policymakers and financial markets.
