Morgan Stanley: $40 Trillion U.S. Debt Constrains Economy but Won't Trigger Collapse
Nashnova编辑部
U.S. federal debt has crossed $40 trillion. Morgan Stanley's global head of fixed-income research, Andrew Sheets, argues high government debt will slow growth — but corporate and household balance sheets have improved in tandem, leaving the conditions for a systemic collapse unmet.
$40 trillion — who actually borrowed all that money?
U.S. federal debt added roughly $20 trillion over the past decade and over $1 trillion in just the last three months.
This means → the borrower is overwhelmingly the government, not the private sector. Corporate debt-to-GDP has been flat for a decade; household debt-to-GDP has actually fallen from 74% in 2019 to about 67% today.
In plain terms = the public ledger is deteriorating, but the private ledger is improving — the two are moving in opposite directions.
Companies are issuing record debt — should we worry?
Corporate bond issuance is hitting all-time highs, driven by surging tech spending and a revival in M&A. Morgan Stanley expects full-year volume to set another record.
Sheets sees the risk as contained: mega-cap tech firms carry low leverage, and the high returns on AI investment justify borrowing even at elevated rates.
This means → companies are borrowing more, but their earnings power is growing too — leverage ratios have not worsened. The report expects credit spreads (the extra yield corporate bonds pay over Treasuries) to widen only modestly.
Can households handle high interest rates?
U.S. household debt-to-GDP stands at roughly 67%, below the 70% of 2000 and down about 6 percentage points from 2019.
The key: a large share of mortgages were locked in during historically low-rate years, while household asset values have risen sharply.
This reflects the deeper reason consumer spending has stayed resilient under dual pressure from high rates and rising energy costs — families' "old loans" carry low rates, and their "new wealth" keeps growing.
Sheets adds a caveat: rate-sensitive sectors such as housing are already subdued, and the speed of households' response to rate changes should not be overestimated.
Is this a uniquely American story — or a global pattern?
In Europe, government debt-to-GDP has risen, but corporate and household deleveraging has been even more pronounced. In Japan, public borrowing has climbed while private-sector leverage has stayed flat.
Sheets attributes this to policy choices: the U.S., France, Japan and others all cut tax rates over the past decade.
In plain terms = governments deliberately chose a "public sector borrows more, private sector carries less" path — the deterioration in public debt is a policy outcome, not a loss of control.
What is the real risk to watch?
The report argues the real pressure point is not companies halting issuance or consumers cutting spending — it is whether investors start to view bonds as offering better risk-reward than equities.
The U.S. 30-year Treasury yield now exceeds expected inflation by roughly 300 basis points; long-duration investment-grade bonds yield 6.2%.
This means → bond attractiveness is already high, yet fund flows and stock-bond correlations show no clear sign of reallocation — equities and bonds have recently moved in the same direction, inconsistent with money migrating from stocks to bonds.
Where does Morgan Stanley see opportunity?
UK inflation-linked bonds (bonds whose returns track inflation) — the UK is one of the few major economies where the fiscal deficit is expected to narrow.
The Australian dollar — Australian government debt-to-GDP is just 49%, paired with an attractive yield differential.
A cautious stance on the U.S. dollar: if the Treasury intervenes more aggressively at the long end of the curve, that would weigh on the greenback.
The firm expects the 7-to-30-year segment of the U.S. Treasury yield curve to re-steepen. This means → long-term bond rates may rise faster than short-term ones, exposing holders of long-dated debt to greater price volatility.
