Rate and refinancing stress
Higher rates and tighter credit are applied to each holding’s debt stack and maturity profile, with sponsor and lender actions stated, to show where liquidity and covenants fail first.

Stress testing private portfolios
Scenario design and stress testing ask how portfolio companies, funds and investors would fare under severe but plausible conditions: rate shocks, closed exit markets, physical disasters, supply failures or technology substitution. In private markets, where history is short and prices are estimated, scenarios often carry more information than statistical models.

02Serlêdan
What scenario design and stress testing does here.
Scenario design and stress testing construct plausible, severe future conditions to examine how pergalan and institutions would perform. They complement probabilistic analysis where data are scarce or futures are deeply uncertain. In capital markets and investment and industry and robotics, stress tests reveal vulnerabilities that arise when several risks materialise together. They inform capital, contingency and coordination plans across sectors. The canonical description is on the STEM Commons.
Physical event across a portfolio
A flood or heat scenario is applied to geocoded sites and key suppliers of every holding, tracing damage and downtime into earnings, insurance recoveries and covenant headroom.
Exit freeze and investor liquidity
Exits are slowed for a stated period while capital calls continue, showing how distributions, secondary sales and fund-level borrowing interact at limited partners.
03Scenario model
Transition and physical risk on a portfolio.
Three scenario families after the NGFS framework move a sector portfolio through carbon costs and warming damages; the transmission view follows the losses to lenders, investors, public finances and households. Scenario: named assumptions about the future, not a forecast.

05Exposure, loss and capital
What stress testing private portfolios means for exposure, loss and capital.
The exposure, loss, scenario and capital views a risk officer, supervisor or ministry of finance would ask for, with the frameworks they report against. Structures follow supervisory and actuarial practice. Values are illustrative: never prices, ratings or advice.
Scenario pathways
How stress testing private portfolios could be stressed under the scenario families central banks and supervisors use.
| Scenario family | Transition risk | Physical risk | What a stress test asks |
|---|---|---|---|
| Orderly | Early, gradual policy | Kêmtir | Can the book absorb a steady repricing? |
| Disorderly | Late, abrupt policy | Lower to medium | What breaks under a sudden repricing and credit migration? |
| Hot house world | Limited policy | High and rising | Where do physical losses concentrate in collateral and insurance? |

How results are checked.
Scenarios are reviewed for plausibility, internal consistency and severity relative to history. Exercise outcomes are compared with actual events when they occur.
| Kontrol bikin | How it is done |
|---|---|
| Severity against history | Each scenario is compared with past episodes and its relative severity stated |
| Internal consistency | Rates, spreads, valuations and exits move together in ways the scenario narrative explains |
| Stated management actions | Sponsor, lender and investor responses are listed and tested with and without them |
| Reverse stress testing | The conditions that would breach a stated tolerance are identified, not only the outcome of a chosen scenario |
Scenario choice can reflect prevailing assumptions and miss novel combinations. Results depend on how participants and models represent responses.
