  7. Key Findings

  8. 三、Optimal CRM Strategy • Passive vs. Positive • Buying-Holding, absorbing total risk • Strict discerning • Continuous monitoring and powerful collecting • Positive • Partially hedging • Outright sales

  9. Passive • the advantage for banks of maximizing their incentive to engage in costly underwriting and monitoring. • The disadvantage is that the bank is fully exposed to any remaining risks in the loan and bears any related costs.

  10. selling or fully hedging • Advantage bank is able to profit from any comparative advantage that it has in finding borrowers without incurring any risks. • A drawback of sales is that doing so may reduce the lender’s incentive to engage in costly evaluation and monitoring of loans. • Hedging • An advantage of hedging is that it reduces risk exposure but not the incentive to undertake costly underwriting and monitoring.

  11. General conclusions • Increase in the riskiness of loans should make loan sales more valuable relative to hedging. • A recession may be associated with an increase in the sale of loans. an increase in interest rates should increase the value of selling loans relative to hedging. • An increase in the returns to monitoring should increase the use of hedging relative to loan sales. • The development of new hedging instruments that reduce basis risk should increase the proportion of loans hedged relative to the loans held in portfolio but not unhedged. • The incentive to hedge should also increase if banks’ capital requirements more accurately reflect the risk reduction associated with hedging.

  12. loan originators • One intuitive finding is that banks that are better monitors are more likely to hedge than sell the credit risk of a loan. • banks operating in areas that are likely to have low default rates would be more likely to sale. • banks with higher tax rates are more likely to sell credit risk than to hedge credit risk using credit derivatives.

  13. across loan types • When applied to the existing market for loan sales and securitization, this implies that banks should sell those loans where the gains from monitoring are low relative to the cost. • more hedging should be done where hedging derivatives for loans are available without large amounts of basis risk.

  15. 1。SMFG's Risk Management System

  16. the manual entitled Regulations on Risk Management. • Risk categories are constantly reviewed, and new categories may be added in response to changes in the operating environment. • The Corporate Risk Management Department works with the Corporate Planning Department to comprehensively and systematically manage all these categories of risk across the entire Group.

  17. The system works as follows: The basic policies for risk management are determined by the Management Committee before being authorized by the Board. The Management Committee, the designated Board members, and the relevant risk management departments perform risk management according to the basic policies.

  18. 2。Credit Risk Management System

  19. The Credit Planning Department within the Corporate Staff Unit is responsible for the comprehensive management of credit risk. This department drafts and administers credit policies, the internal rating system, credit authority guidelines, credit application guidelines, and manages NPLs, and other aspects of credit portfolio management.

  20. The Corporate Research Department within the Corporate Services Unit performs research on industries as well as investigates the business situations of borrower enterprises to detect early signs of problems or growth potential. The Credit Administration Department is responsible for handling NPLs of borrowers classified as potentially bankrupt or lower, and draws up plans for their workouts, including write-offs, and corporate rehabilitation.

  21. The credit departments within each business unit conduct credit risk management for loans handled by their units and manage their units' portfolios. The credit limits they use are based on the baseline amounts established for each grading category, with particular attention paid to evaluating and managing customers or loans perceived to have particularly high credit risk.

  22. The Credit Review Department, operating independently of the business units, audits asset quality, accuracy of gradings, self-assessment, and state of credit risk management, and reports the results directly to the Board of Directors and the Management Committee. SMBC has established the Credit Risk Committee, a new consultative body, to round out its oversight system for undertaking flexible and efficient control of credit risk, and ensuring the overall soundness of the bank's loan operations.

  23. 2。Relationship between Risk Management Framework and Risk Category at SMBC

  24. risk capital-based management method allocates capital effectively to each department according to its role in business strategies to keep total exposure to credit, market, and operational risks within the scope of assigned capital. • Liquidity risk is managed within the context of maximum limits set for asset liability management (ALM) and the funding gap. • The purpose of credit risk management is to keep credit risk exposure to a permissible level relative to capital, to maintain the soundness of assets, and to ensure returns commensurate with risk.

  25. 3。Credit Risk Assessment and Quantification • Internal Rating System • two indicators: the obligor grading, which indicates the creditworthiness of a borrower; and the facility grading, which shows the probability of collecting for each facility. • Facility gradings are assigned based on the borrower's obligor grading and transaction terms such as guarantee, tenure, and collateral • Overseas credits are subjected to a further analysis that takes into account country ranking, an indicator derived from analyses of each country's political and economic situation, international balance of payments, and external debt burden

  26. Quantification of Credit Risk • probability of default • concentration of risk on a specific customer or industry • fluctuations in the value of collateral, such as real estate and securities • probability of grade migration • loss given default • credit quality correlation among obligors • a simulation of 10,000 iterations of simultaneous default using the Monte Carlo method to calculate our maximum loss exposure

  27. 4。Framework for Managing Individual Loans • Credit Assessment • a variety of financial analyses, including cash flow, to predict an enterprise's capability of loan repayment and its growth prospects • qualitative analyses of industrial trends, the enterprise's R&D capabilities, the competitiveness of its products or services, and its management caliber • To respond proactively and promptly to customers' funding needs-particularly those of small and medium-sized enterprises (SMEs)we employ a standardized credit risk assessment process for SMEs that uses a credit-scoring model.

  28. mortgage loans for individuals, we employ a credit assessment model based on credit data amassed and analyzed by SMBC over many years. This model enables our loan officers to efficiently make rational decisions on mortgage loan applications, and to reply to the customers without delay. It also facilitates the effective management of credit risk, as well as the flexible setting of interest rates.

  29. Credit Monitoring System

  30. 5。Framework for Credit Portfolio Management • management of credit portfolio to maintain and improve its soundness and profitability over the medium to long term. • Risk-Taking within the Scope of Capital • To keep credit risk exposure to a permissible level relative to capital, SMBC sets credit risk capital limits for internal control purposes. Under these limits, separate guidelines are issued for each business unit and marketing unit. Also issued are specialized guidelines for each business unit and business type, such as real estate finance, fund investment, and investment in securitization products. Regular monitoring is conducted to check that these guidelines are being followed, thus ensuring appropriate overall management of credit risk.

  31. Controlling Concentration Risk • Because concentration of credit risk in an industry or corporate group has the potential to substantially impair capital, SMBC implements measures to prevent excessive concentration of loans in an industry and to control large exposure to individual companies or corporate groups by setting guidelines for maximum loan amounts. To manage country risk, SMBC also has credit limit guidelines based on each country's creditworthiness.

  32. New Type of Unsecured Loans, and Balancing Risk and Returns • Against the background of increasing sophistication in methods of managing credit risk, SMBC actively engages in a new type of unsecured loans. Meanwhile, the bank runs credit operations on the basic principle of earning returns that are commensurate with the credit risk involved, and makes every effort to reduce capital and credit costs as well as general and administrative expenses

  33. Reduction and Prevention of Non-Performing Loans • On non-performing loans (NPLs) and potential NPLs, SMBC carries out regular loan reviews to clarify handling policies and action plans, enabling it to swiftly implement measures to prevent deterioration of borrowers' business situations, support business recoveries, collect on loans, and enhance loan security. • Toward Active Portfolio Management • SMBC makes active use of credit derivatives, loan securitization, and other instruments to proactively manage its portfolio
