While overall net government bond issuance is forecast to drop 13%, this is solely due to the U.S. When measured by duration (10-year Treasury equivalents), gross supply is actually projected to increase by 1% year-over-year. This presents a more challenging picture for markets than the headline number suggests.

Politicians will continue running large deficits as long as the bond market tolerates it by keeping interest rates low. The ultimate correcting mechanism for government spending isn't political discipline, but the bond market's impersonal decision to raise rates, forcing fiscal responsibility.

A proposed plan to shift the Fed’s holdings to short-term T-bills forces the government to refinance its massive debt stack every year at prevailing market rates. This creates enormous risk, making the U.S. government's financial position resemble a homeowner with a giant adjustable-rate mortgage, vulnerable to catastrophic payment shocks if rates rise.

With debt-to-GDP at 100% and rising deficits, the U.S. faces severe fiscal strain. An economist argues that political will for tax hikes and spending cuts is absent and will likely only materialize after a forcing event, such as a crisis in the bond market where interest rates spike.

Historically, surges in U.S. public debt have consistently led to periods of negative real interest rates. This suggests that the sheer weight of government debt creates a structural constraint, forcing markets to keep real rates capped, irrespective of short-term inflation or central bank policy.

The Treasury actively stimulates liquidity by altering its debt issuance strategy. By issuing more short-term T-bills (bought by banks) and fewer long-term bonds, it effectively monetizes fiscal spending. This 'Treasury QE' is a major, under-the-radar source of liquidity for markets.

Despite recent concerns about private credit quality, the most rapid and substantial growth in debt since the GFC has occurred in the government sector. This makes the government bond market, not private credit, the most likely source of a future systemic crisis, especially in a rising rate environment.

Lacking demand for long-term bonds, the Treasury issues massive short-term debt. This requires a larger cash balance (TGA) to avoid failed auctions, draining liquidity from the very markets needed to finance this debt, creating a self-reinforcing crisis dynamic.

Faced with high debt loads, developed markets like the UK are adopting policies typical of emerging markets. This "financial repression" involves treasury and central bank coordination to manage debt issuance—favoring short-term debt over long-term—to artificially suppress yields on 10- and 30-year bonds and avoid a sovereign debt crisis.
