Rogue trading and misleading reporting, including the Barings case

 Rogue Trading

  • Leeson’s role expanded to conducting proprietary arbitrage trades exploiting perceived pricing differentials on futures contracts listed concurrently on the largest stock exchange in Japan (i.e., the Nikkei) and the second largest stock exchange in Japan (i.e., the Osaka Securities Exchange). 
  •  Leeson decided to take the rogue action of speculating in a directional move by only buying one asset without an offsetting short position.
  • Leeson also controlled the back-office accounting of his own trades, and he managed the reporting through a hidden reconciliation account that was never reported to the home office. What appeared to be a £102 million profit in 1994 was actually a £200 million loss. 
  • In late 1994, the risk managers at Barings Bank grew curious about the unusual gains that Leeson was producing relative to the types of trades he was making.
  • Risk managers continued their interest when, in January 1995, Leeson reported an unusual profit of £10 million in a single month. Once again, their concerns were dismissed.
  • The actual losses grew so large that the bank was forced to liquidate. A Dutch Bank, ING, acquired Barings Bank
  • If profits appear to be either outsized or strangely consistent, then scrutiny is needed to ensure that the books are being kept correctly. 
  • There should also be an independent verification mechanism, and the back-office should never be controlled by front-office (i.e., traders) influencers

Market Risk Problem 1 - Calculate VaR using Parametric approach

 Assume that the profit/loss distribution for XYZ is normally distributed with an annual mean of $15 million and a standard deviation of $10 million. Calculate the VaR at the 95% and 99% confidence levels using a parametric approach. Given Data Distribution : Normal. Mean ( μ \mu μ ) : $15 million (annual). Standard deviation ( σ \sigma σ ) : $10 million (annual). Confidence levels : 95% ( z = 1.645 z = 1.645 z = 1.645 ). 99% ( z = 2.33 z = 2.33 z = 2.33 ). Formula for VaR The parametric VaR formula is: VaR = ∣ z ∣ ⋅ σ − μ \text{VaR} = |z| \cdot \sigma - \mu VaR = ∣ z ∣ ⋅ σ − μ ∣ z ∣ |z| ∣ z ∣ : z-score corresponding to the confidence level. σ \sigma σ : Standard deviation (risk/volatility). μ \mu μ : Mean (expected gain/loss). Step-by-Step Calculations 1. VaR at 95% Confidence Level ( z = 1.645 z = 1.645 z = 1.645 ) VaR 95 = ∣ 1.645 ∣ ⋅ 10 − 15 \text{VaR}_{95} = |1.645| \cdot 10 - 15 VaR 95 ​ = ∣1.645∣ ⋅ 10 − 15 VaR 95 = 16.45 − 15 = 1.45  million . \text{VaR}_{95} = 16.45 -...

Market Risk : Estimate VaR using a historical simulation approach

  What is VaR? Value at Risk (VaR) measures the potential loss in value of a portfolio over a defined time period for a given confidence level. It answers the question: "How much could I lose with x % x\% x % confidence over t t t days?" Historical Simulation Approach This is a non-parametric method that uses actual historical returns to estimate potential future losses. It assumes that the past distribution of returns is representative of the future. Steps to Estimate VaR using Historical Simulation Collect Historical Data Gather historical price data for the assets in the portfolio. Calculate daily returns for each asset using: r t = P t − P t − 1 P t − 1 r_t = \frac{P_t - P_{t-1}}{P_{t-1}} r t ​ = P t − 1 ​ P t ​ − P t − 1 ​ ​ where P t P_t P t ​ is the price on day t t t . Simulate Portfolio Returns Compute the daily portfolio return for each historical period. For a portfolio with n n n assets: R t = ∑ i = 1 n w i ⋅ r i , t R_t = \sum_{i=1}^n w_i \cdot r_{i,t} R ...

CREDIT RISK TRANSFER MECHANISMS

 CREDIT RISK TRANSFER MECHANISMS Credit default swaps (CDSs) are financial derivatives that pay off when the issuer of a reference instrument (e.g., a corporate bond or a securitized fixed income instrument) defaults. This is a very direct way to measure and transfer credit risk. These derivatives function like an insurance contract in which a buyer makes regular (quarterly) premium payments, and in return, they receive a payment in the event of a default. Advantages of CDSs include: Spur innovation . This enables them to fund riskier opportunities  Cash-flow potential. CDS sellers create a stream of payments that could be a significant source of cash flow. Theoretically, they can diversify the CDS contracts  across industries and geographies such that defaults in one area should be offset by fees from CDSs that have not been triggered through default. Risk price discovery. The use of a CDS enables price discovery of a specific credit risk. A CDS is a pure play on ...
