  • The Interest Rate Parity (IRP) Is a Theory Regarding the Relationship
    What is the Interest Rate Parity (IRP)? The interest rate parity (IRP) is a theory regarding the relationship between the spot exchange rate and the expected spot rate or forward exchange rate of two currencies, based on interest rates. The theory holds that the forward exchange rate should be equal to the spot currency exchange rate times the interest rate of the home country, divided by the interest rate of the foreign country. Uncovered Interest Rate Parity vs Covered Interest Rate Parity The uncovered and covered interest rate parities are very similar. The difference is that the uncovered IRP refers to the state in which no-arbitrage is satisfied without the use of a forward contract. In the uncovered IRP, the expected exchange rate adjusts so that IRP holds. This concept is a part of the expected spot exchange rate determination. The covered interest rate parity refers to the state in which no-arbitrage is satisfied with the use of a forward contract. In the covered IRP, investors would be indifferent as to whether to invest in their home country interest rate or the foreign country interest rate since the forward exchange rate is holding the currencies in equilibrium. This concept is part of the forward exchange rate determination. What is the Interest Rate Parity (IRP) Equation? The covered and uncovered IRP equations are very similar, with the only difference being the substitution of the forward exchange rate for the expected spot exchange rate. The following shows the equation for the uncovered interest rate parity: The following

  • Interest Rate Risk and Market Risk Lr024
    INTEREST RATE RISK AND MARKET RISK LR024 Basis of Factors The interest rate risk is the risk of losses due to changes in interest rate levels. The factors chosen represent the surplus necessary to provide for a lack of synchronization of asset and liability cash flows. The impact of interest rate changes will be greatest on those products where the guarantees are most in favor of the policyholder and where the policyholder is most likely to be responsive to changes in interest rates. Therefore, risk categories vary by withdrawal provision. Factors for each risk category were developed based on the assumption of well matched asset and liability durations. A loading of 50 percent was then added on to represent the extra risk of less well-matched portfolios. Companies must submit an unqualified actuarial opinion based on asset adequacy testing to be eligible for a credit of one-third of the RBC otherwise needed. Consideration is needed for products with credited rates tied to an index, as the risk of synchronization of asset and liability cash flows is tied not only to changes in interest rates but also to changes in the underlying index. In particular, equity-indexed products have recently grown in popularity with many new product variations evolving. The same C-3 factors are to be applied for equity-indexed products as for their non-indexed counterparts; i.e., based on guaranteed values ignoring those related to the index. In addition, some companies may choose to or be required to calculate part of the RBC on Certain Annuities under a method using cash flow testing techniques.

Major Index-based financial instruments bring transparency and efficiency to both sides of risk transfer, to investor and hedger alike. Unfortunately, to the extent that an index is anonymous and commoditized, it cannot correlate perfectly with a specific portfolio. Thus, hedging with index-based financial instruments brings with it basis risk. The result is “significant practical and philosophical barriers” to the financing of propertykasualty catastrophe risks by means of catastrophe derivatives (Foppert 1993).

  • Factors That Shape an Organisation‟S Risk Appetite: Insights from the International Hotel Industry
    Oxford Brookes University FACTORS THAT SHAPE AN ORGANISATION‟S RISK APPETITE: INSIGHTS FROM THE INTERNATIONAL HOTEL INDUSTRY Xiaolei Zhang Thesis submitted in partial fulfilment of the requirements of the award of Doctor of Philosophy December 2016 ABSTRACT Since the 2008 global financial crisis, a major challenge for the Board of Directors (BoD) and risk managers of large, public corporations has been to clearly define and articulate their company‟s risk appetite. Considered as a business imperative to ensure successful enterprise risk management, risk appetite has been widely discussed among practitioners and, more recently, academics. Whilst much emphasis has been placed upon defining risk appetite and identifying the ways in which an organisation‟s risk appetite statement can be articulated, the literature has largely ignored the critical idea that risk appetite is not a „static picture‟, but changes over time according to a variety of factors residing in the organisation‟s internal and external contexts. Using the international hotel industry as research context, this study explores the underlying factors that shape an organisation‟s risk appetite. Building on the „living organisation‟ thinking and employing the „living composition‟ model as a conceptual lens, this thesis integrated several strands of literature related to risk appetite, organisational risk taking and individual risk taking, and developed a conceptual framework of factors that shape an organisation‟s risk appetite. Given the scarcity of risk appetite research, an exploratory, qualitative approach was adopted and the fieldwork was conducted in two stages: stage one served to gain a generic-business perspective of the main factors that shape an organisation‟s risk appetite.

  • Banking on Deposits: Maturity Transformation Without Interest Rate Risk
    THE JOURNAL OF FINANCE • VOL. LXXVI, NO. 3 • JUNE 2021 Banking on Deposits: Maturity Transformation without Interest Rate Risk ITAMAR DRECHSLER, ALEXI SAVOV, and PHILIPP SCHNABL ABSTRACT We show that maturity transformation does not expose banks to interest rate risk— it hedges it. The reason is the deposit franchise, which allows banks to pay deposit rates that are low and insensitive to market interest rates. Hedging the deposit fran- chise requires banks to earn income that is also insensitive, that is, to lend long term at fixed rates. As predicted by this theory, we show that banks closely match the interest rate sensitivities of their interest income and expense, and that this insu- lates their equity from interest rate shocks. Our results explain why banks supply long-term credit. A DEFINING FUNCTION OF BANKS is maturity transformation—borrowing short term and lending long term. This function is important because it sup- plies firms with long-term credit and households with short-term liquid de- posits. In textbook models, banks engage in maturity transformation to earn the average difference between long-term and short-term rates, that is, to earn the term premium. However, doing so exposes them to interest rate risk: an unexpected increase in the short rate increases banks’ interest expense Itamar Drechsler is at the Wharton School, University of Pennsylvania.

The ICAAP is reviewed by the Financial Conduct Authority (‘FCA’) through a Supervisory Review and Evaluation Process (‘SREP’); and • Pillar 3 requires a firm to disclose specific information concerning its risk management policies and procedures as well as the firm’s regulatory capital position. From 1 January 2014, Marex Spectron Group Limited (‘the Group’) was required to comply with Basel III requirements, which are implemented through the Directive and the Capital Requirement Regulation (‘CRR’), collectively referred to as CRD IV. These regulations are also implemented in the UK through the Prudential Sourcebook for Investment firms (IFPRU) and Prudential Sourcebook for Banks, Building Societies and Investment firms (BIPRU). This document contains the disclosures outlined in Part Eight of the CRR and FCA BIPRU 11, fulfilling the disclosure requirements under these regimes and making them accessible to clients and market participants.

Appendix 2 SEABURY CAPITAL Best's Enterprise Risk Model Based on Value-at-Risk methodology, A.M. Best and Seabury jointly created A.M. Best’s Enterprise Risk Model (ERM) which should assess insurance companies’ risks more accurately. Our objectives for ERM are: • Consistent with state of art risk management concepts - Value at Risk (VaR). • Simple and transparent methodology. • Risk parameters are based on current market data. • Risk parameters can be easily updated annually. • Minimum burden imposed on insurance companies to produce inputs. • Explicitly models country risk. • Explicitly calculates the covariance between all of a company’s assets and liabilities globally. • Aggregates all of an insurance company’s risks into a composite risk measure for the whole insurance company. 3 SEABURY CAPITAL Best's Enterprise Risk Model will improve the rating process, but it will also generate some additional costs Advantages: ■ Based on historical market data ■ Most data are publicly available ■ Data is easily updated ■ The model can be easily expanded to include more risk factors Disadvantages: ■ Extra information request for the companies ■ Rating analysts need to verify that the companies understand the information specifications ■ Yearly update of the Variance-Covariance matrix 4 SEABURY CAPITAL Definition of Risk ■ Risk is measured in standard deviations.
