Debt, Buybacks, and Your TSP

What “debt to GDP” actually means

GDP, or Gross Domestic Product, is the total value of everything the US economy produces in a year. Debt to GDP compares what the government owes to that yearly output. Think of it like comparing a mortgage balance to annual household income. A bigger number means a heavier load relative to what is coming in.

Debt held by the public sits at roughly 99 to 101% of GDP. The Congressional Budget Office projects that ratio climbing past the post-World War Two record by 2030 and reaching 120% by 2036 if nothing changes.

The government now pays more each year in interest on its debt than it spends on national defense. Interest costs have crossed roughly $1.1 to $1.2 trillion a year, up from $352 billion five years ago. CBO expects that figure to roughly double again by 2036.

A federal pay freeze proposal does not happen in isolation. It happens inside a budget under this kind of pressure.

Treasury buybacks, in plain English

A bond is a loan you give to a borrower, in this case the US government, in exchange for regular interest payments and your money back at the end. When the Treasury Department does a buyback, it repurchases some of its own older bonds before they mature, using cash raised from newer debt sales.

This is not the same as the Federal Reserve’s stimulus programs. The Fed controls short-term interest rates and its own balance sheet. Treasury buybacks are a debt management tool aimed at keeping the bond market functioning smoothly. Think of it as tidying an overcrowded shelf, not printing new money.

On August 19, 2026, Treasury doubled the size of its long-term buyback operations, from $2 billion to at least $4 billion per operation, focused on bonds maturing in 10 to 30 years. Bond yields fell right after the announcement, with the 10-year dropping to about 4.65% and the 30-year to about 5.2%.

One analyst called the buybacks a rearrangement of the maturity schedule, not a debt reduction. It eases pressure. It does not erase the underlying problem.

Where inflation fits

July’s inflation report showed prices up 3.4% over the year, with the core rate at 2.5%. Both remain above the Federal Reserve’s 2% target.

When inflation runs hot, the Fed keeps rates higher for longer. Higher rates mean the government pays more to borrow and refinance. More interest expense adds to the deficit, which means more bonds get issued, which is the pressure the buybacks are trying to manage. It is a loop.

What this means for you

FERS employees and USPS workers with money in the G Fund. This backdrop is part of why the G Fund rate sat at 4.875% for August. The G Fund pays a rate based on the average yield of longer-term Treasury securities, and it resets monthly.

Retirees drawing Social Security, a FERS pension, and TSP income. Sticky inflation is why the cost of living adjustment estimate sat at 3.6% rather than near zero. Inflation above target is not good news generally, but it does real work protecting buying power through the COLA formula.

S Corp owners and high earners carrying debt. A higher-for-longer rate environment means borrowing costs stay elevated longer than they would in a calmer fiscal picture.

Risks and trade-offs worth naming

Treasury buybacks can ease short-term stress without solving the underlying debt trajectory. CBO projections assume no policy changes, and policy changes constantly. G Fund rates move every month. Inflation readings can surprise in either direction. Nothing here is a guarantee about where rates, inflation, or the debt path actually go.
