I am not worried about US public debt

 The issue of high and rising US public debt is a subject matter of public discussion in Indian streets. Using a common Dalal Street phrase I can say that every paanwalla, taxi driver, and barber is now discussing how unsustainable US public debt is. For example, listen to this boy .

From top economists, analysts, and global strategists to a common man on the street, all are worried about an imminent US default and its impact on the global financial system, especially the developing and underdeveloped countries.

Currently, the US public debt is close to US$35trn (Appx 125% of annual GDP) and is projected to double in the next eight years. The current US government's annual interest payments are more than US$1trn (Appx 20% of annual federal revenue; 14% of annual federal spending and 4% of GDP). The average interest rate on the entire debt is less than 3% p.a.

As of June 2023, 43% of this debt was owned by the Federal Reserve System and State and Local Governments. 32% of the debt was owned by various domestic institutions (MF, Insurance, Pension, and Depositories, etc.) The balance 26% was owned by other institutions including foreign governments. Almost the entire debt is denominated in USD.

This debt level is a matter of concern but does not prima facie appear to be at a disaster level. The worrisome part is that about one-third of US public debt is short-term (12 months or less maturity). However, considering that a large part of this debt could be owned by the government institution and the Federal Reserve System, refinancing of this debt should not pose a significant problem. In my view, US debt could be sustained with 3-4% inflation, 20% USD devaluation, 5% revenue growth (higher taxes), and rationalization/reimbursement of various war funding expenses, this debt could be sustained, reduced, and serviced. It is of course going to be hard for US savers and middle classes for a decade or so. USD losing its reserve currency status may be collateral damage.

For context, as per the interim budget for FY25, India’s central government debt was ~Rs172trn as of 31^st March 2024. This is approximately 58% of GDP. 3% of this debt is held by foreign entities. However, using the standard IMF definition India’s Debt to GDP ratio is ~82%. Since most of this debt is INR-denominated and RBI is holding a strong US$650bn forex chest, servicing is not an issue.

However, as per FY24BE, interest expense would account for 25% of total government expenditure, after material cuts in subsidies. For a developing economy, this interest expense to government revenue expenditure is considered worrisome, as it hampers investments, keeps fiscal deficit high, makes interest rate cuts difficult, leads to lower social expenditure affecting the quality of life, and hampers further market borrowing capability of the government.

The small point is that investors in Indian securities should be more concerned about seemingly unsustainable public debt in India rather than the high debt levels of developed countries.

As a small investor with zero risk appetite, I keep a cushion for lower subsidies, late payments of government dues, higher effective taxes, small probability of higher rates in my investment strategy.
