From $3trn to $5trn: Private Credit's Growth Is Now a Banking Question
The comfortable story about private credit is that it moved risk out of the banking system. Loans that once sat on bank balance sheets now sit in closed-end funds financed by long-term institutional capital. No deposits, no runs, no taxpayer.
That story is getting harder to tell.
Private credit stands at roughly $3 trillion globally as of early 2025 and is projected to reach approximately $5 trillion by 2029. Growth of that magnitude does not happen in isolation — and the connections back to banks are thickening as it goes.
Three channels back to the banking system
- Warehouse lines. Funds finance origination with bank credit facilities. The loan may leave the bank balance sheet, but the leverage behind it often does not.
- Derivatives hedging. Currency and rate hedges on cross-border exposures are bank-intermediated. The counterparty is a bank.
- Formal partnerships. Banks originate and distribute into private credit vehicles, retaining relationships, sometimes retaining risk, and frequently retaining reputational exposure.
Risk that travels through these channels has not been eliminated. It has been relocated and made harder to see — which is a different thing, and arguably a worse one for anyone trying to measure system-wide exposure.
Why definitional vagueness is a supervisory problem
"Private credit" has no universally accepted meaning. The boundary with leveraged lending, direct lending, speciality finance and structured credit is drawn differently by different institutions.
That sounds like taxonomy. It is actually measurement. If the perimeter is ambiguous, then:
- Aggregate exposure figures are not comparable across sources.
- Bank interconnection cannot be summed reliably.
- Concentration — already extreme, with the top 10 corridors carrying 68% of cross-border volume — is measured against a denominator nobody agrees on.
You cannot supervise a perimeter you cannot define.
What the numbers say about resilience
Our research on 13,317 transactions worth $11.8 trillion offers three findings that bear directly on the "risk moved somewhere safer" claim:
- Cross-border deals default at 6.46% versus 2.56% domestically — a 3.91pp premium with a 2.86 hazard ratio. The growth has been disproportionately cross-border.
- Concentration is extreme, so losses correlate through common corridors rather than diversifying.
- Under severe stress, capital adequacy falls from 4.9% to 3.5-3.6% — approaching regulatory minima.
None of that says private credit is unsound. Its closed-end structure genuinely removes run risk, and its maturity wall imposes borrower discipline banks often cannot. But "structurally different" is not the same as "structurally safer", and the interconnection channels mean the two systems are not separable in a downturn.
The question worth asking now
Not "is private credit risky?" — every credit market is. The better question:
If the projected $2 trillion of growth arrives, how much of it lands back on bank balance sheets through warehouse lines, hedges and partnerships — and does anyone measure that in one place?
For banks with private credit interconnection, the practical implication is that it belongs in ICAAP as an explicit exposure with its own stress narrative, not as an assumed diversification benefit.
If you need that quantified for your own book — corridor concentration, cross-border adjustment, stressed capital impact — that is what our economic capital assessment is built to do.
