OSFI STRESS TESTING

4 PURPOSES of stress testing program

(1) RISK IDENTIFICATION and CONTROL
-consider concentrations and interactions between risks in stress environments that could be overlooked-

(2) COMPLEMENTARY PERSPECTIVE to RM tool
-provide insights about validity of statistical models-

(3) support CAPITAL management
-identify severe events that could adversely impact the company

(4) improve LIQUIDITY management

2

OSFI STRESS TESTING

3 general considerations for stress testing programs

1) ACCOUNT FOR VIEWS FROM EXPERTS ACROSS THE ORGANIZATION

2) DOCUMENTED appropriately in a PROCEDURE governing the stress testing program

3) ROBUST INFRASTRUCTURE, but FLEXIBLE ENOUGH for evolving stress test.

4) Regularly UPDATE STRESS TESTING FRAMEWORK. Effectiveness assessed REGULARLY AND INDEPENDENTLY.

3

OSFI STRESS TESTING

3 relevant risks that may be included in stress testing

1) CREDIT RISK
eg. counterparty, reinsurance

2) MARKET RISK
eg. interest rate, foreign exchange

3) INSURANCE RISK
eg. freq/sev, liquidity, legal, concentration, regulatory, reputation)

4

OSFI STRESS TESTING

4 measures used to evaluate the impact of stress tests

1) A/L values

2) regulatory capital (available and required)

3) economic capital

4) liquidity

5

OSFI STRESS TESTING

3 features of methodology and scenario selection for stress testing

1) cover a range of TYPE OF RISKS and BUSINESS AREAS
eg. credit, market, insurance

2) cover a range of SCENARIOS (incl. NON-HISTORICAL SCENARIOS)
must be imaginative!

3) cover a range of SEVERITIES (incl. events capable of generating the most damages)

6

OSFI STRESS TESTING

Contrast :
STRESS TEST
and
REVERSE STRESS TEST

--stress test--
test outcome arising from changes in circumstances.

--reverse stress test--
-START WITH OUTCOME OF BUSINESS FAILURE
-BACKWARDS, FIND WHAT SCENARIOS could bring that outcome
-determine if the scenario is PLAUSIBLE

7

OSFI STRESS TESTING

When reverse stress test prove to be useful

to uncover HIDDEN RISK and INTERACTIONS among risks

8

OSFI STRESS TESTING

4 specific risks requiring attention in light of experience of financial market turmoil

1) Risk MITIGATION (reinsurance)

2) risk to REPUTATION

3) risk of CONCENTRATION
(in regions,in a single risk factor, in off-balance sheet exposure)
4) COUNTERPARTY CREDIT risk

9

OSFI STRESS TESTING

3 elements OSFI may want to assess in cie's stress testing programs (as per of the Supervisory Review Process)

1) whether chosen scenarios are consistent with risk appetite

2) whether chosen scenarios are appropriate to portfolio of cie and if they include severe shock factors

3) whether frequency of stress testing is sufficient to support timely management action.

3) assess future capital RESSOURSES and capital REQUIREMENTS under adverse scenarios

10

OSFI STRESS TESTING

2 responsibilities
of BOARD
with STRESS TESTING program

1) ULTIMATELY RESPONSIBLE for overall stress test program

2) be AWARE OF KEY FINDINGS
----
3) that Sr. Mngmnt has a stress test program that is ENTERPRISE WIDE and "FIT FOR PURPOSE"

4) ensure that policies requiring the use of stress testing as a management tool are in place

11

OSFI STRESS TESTING

2 responsibilities of
SENIOR MANAGEMENT
with STRESS TESTING program

1) its IMPLEMENTATION, MANAGEMENT and OVERSIGHT

2) ensure that cie has PLAN TO DEAL WITH RARE BUT PLAUSIBLE STRESS SCENARIOS
---
3) able to ARTICULATE RISK APPETITE

4) UNDERSTAND IMPACT OF STRESS EVENTS ON RISK PROFILE

5) identify POTENTIAL STRESS SCENARIOS and IMPLEMENT MITIGATION STRATEGIES

5) Document the use of severe scenarios.

12

OSFI STRESS TESTING

Define Stress testing

RM technique to evaluate the POTENTIAL EFFECT OF FINANCIAL CONDITION of a set of changes in risk factors from EXCEPTIONAL BUT PLAUSIBLE EVENTS

13

OSFI STRESS TESTING

2 types of stress testing

Sensitivity testing

Scenario testing

14

OSFI STRESS TESTING

Contrast
SCENARIO TESTING
and
SENSITIVITY TESTING

--scenario testing--
-HYPOTHETICAL FUTURE STATE OF THE WORLD
-involves changes in a number of risk factors (as well as ripple effects)
-conducted over the appropriate time horizon
-more complex

--sensitivity testing--
INCREMENTAL CHG IN A RISK FACTOR
-conducted over a SHORTER TIME HORIZON
-needs FEWER RESSOURCES than scenario testing
-simpler technique for assessing the impact of a change in risks when a quick response is needed

15

OSFI STRESS TESTING

How a stress testing program can provide a different risk perspective than other RM tools

-provide insight on validity of other stat models at high confidence intervals (VaR)

-assess robustness of models to changes in financial environment

-detect hidden concentrations and interactions overlooked by other models

16

OSFI STRESS TESTING

2 possible outcomes of failure of imagination when performing stress tests

1) underestimation of likelihood and severity of extreme events

2) false sense of security

17

OSFI STRESS TESTING

2 times when stress testing proves to be especially important

AFTER LONG PERIOD OF CALM FINANCIAL CONDITION
where memory of negative position starts to fade, leading to complacency and underpricing

DURING PERIOD OF EXPANSION
when innovation leads to new products, rapid growth, and no historical experience is available
