Credit scoring is a technique used by financial institutions to assess the creditworthiness of potential borrowers. This involves evaluating a borrower's credit history to predict the likelihood of defaulting on a loan. This paper presents an ensemble of two Transformer based models within a framework for discriminating the default risk of loan applications in the field of credit scoring. The first model is FinBERT, a pretrained NLP model to analyze sentiment of financial text. The second model is FT-Transformer, a simple adaptation of the Transformer architecture for the tabular domain. Both models are trained on the same underlying data set, with the only difference being the representation of the data. This multi-modal approach allows us to leverage the unique capabilities of each model and potentially uncover insights that may not be apparent when using a single model alone. We compare our model with two famous ensemble-based models, Random Forest and Extreme Gradient Boosting.

International factoring is very useful to transfer credit risk, to promote cash flow, to collect debt and to reduce cost and expenses. However, International factoring system in china shows imperfection especially in gap of legal vacuum and its limit to be developed. Here I suggest a practical alternative for development of International factoring system in china as follow. First, legal environment in China for factoring system should be rearranged. Even law and contract law have relative clauses for factoring system there are many difficulty to be applied. It is necessary to prepare legal ground for factoring system. Second, without recourse for International factoring system should be fixed. Without recourse is the essential point for factoring system in international trade. In fact chinese factors are partially applied only for those big global companies. However International factoring system is especially useful for small-medium companies lacked of a good credit rating. It is necessary to promote special factors by combining financial organizations as it does in developed countries. Third, they need to make legal ground to prohibit unlicensed factoring companies. Forth, they need to educate usefulness of factoring system. The settlement system in China is to be developed by systematic researches and promotion for International factoring system.

Documentary letters of credit including standby letters of credit are governed by the independence or abstraction rule and the doctrine of strict compliance. Since the former rule requires the issuing bank to honor the drafts regardless of the defective performance of the underlying contract, the applicant(the customer) will be without a remedy if he is unable to make himself whole by litigation on the underlying contract. Therefore, the applicant is exposed to a risk much higher than in the commercial letters of credit. The Uniform Customs and Practice for Documentary Credit(UCP) has no provisions allowing legal relief for the applicant on the abuse of L/C by unscrupulous beneficiary, but UCC ${\S}5-114$ has provision allowing injunctive relief for the applicant. In this paper, I attempted to clarify certain standards of injunctive relief available for the customer in the credit. When there is fraud in the L/C transaction by any of the parties concerned, we must weigh the principle of independence or abstraction and the fraud rules. According to banking practice and judicial precedence, we need not keep the principle of independence and abstaction even in fraudulent transaction and the bona fide sufferer must be protected. The purpose of this paper is to review the studies of Fraud rule and the Injunction and to suggest the applicable standards for the Injunction therory under letters of credit. Specially this paper analysed the following ; (1) the guideline for the fraud (exception) rule to the autonomy principle, (2) the appilcable standards of the Injunction, and (3) the implications on parties concerned in letters of credit transaction. Conclusively, the Injunction should be granted if (1) there is clear proof of fraud (2) the fraud constitutes fraudulent abuse if the independent purpose of L/C (3) irreparble injury might follow if injunction is not granted or the recovery of damages would be seriously endangered.

In the case of Banque Paribas V. Banco Santander in England for the reimbursement request of deferred payment credit by the nominated bank, the L/C-issuing bank refused to pay the proceeds at maturity because of a fraudulent transaction. The reason of refusal was that the nominated bank, Banco Santander, had no right of payment in deferred credit before its maturity if it made payment of proceeds without notice to the issuing bank, that is, payment not based upon a credit transaction but on its own account. However, in the case of ADIB V. Fortis Bank in America, the New York court made the decision that the deferred payment bank could not refuse to reimburse to the nominated bank, Fortis Bank, because of fraud. Its decision was based on the UCP600. We have analyzed and investigated the above two cases-one was an English court's decision and the other an American's. The English court's decision was made under UCP500, but the American court's was made under UCP600, which was revised in 2007. As a result, we can expect that from now on in deferred payment credit transactions, the power of the nominated bank will be greater than before, but the issuing bank will bear the risk of the beneficiary's fraud, so the issuing bank will be hesitant to issue deferred payment credit. Notwithstanding, we thought that the New York court decision would come into effect in the activation of deferred payment credit in practical trade transactions.

In the past, when the credit card was delivered to the customer, the postal agreement and receipt were signed by customer. The repossessed documents were sent back to the card company through the reorganization process. The card company checks the error by scanning and keeps it in the document storage room. This process is inefficient in cost and personnel due to delivery time, document print out, document sorting, image scanning, inspection work, and storage. Also, the risk of personal data spill is very high in the process of providing personal information. The proposed system is a service that receives a postal agreement and a receipt to a recipient when signing a credit card, signing the mobile image instead of paper, and automatically sending it to the card company server. We have designed a system that can protect the cost of paper documents, complicated work procedures, delivery times and personal information. In this study, we developed 'u-paperless' and secure credit card delivery system applying electronic document and security system.

The study aimed to study the effect of the inflation rate, the real domestic product, the interbank lending interest rate, and the total deposits on credit facilities in Jordan for 2012-2021 through quarterly data. The study adopted the ARDL model. The study used the time series analysis method, as the study tests the stationarity of the time series. The results showed that the impact of inflation on the total credit facilities was negative. In contrast, the impact of each of the total deposits, real GDP, and the interest rate of interbank loans on the total credit facilities was positive and significant. The study recommended the need for the banking sector in Jordan to develop risk management mechanisms in a way that allows it to adapt to economic cycles and crises by conducting stress tests and developing scenarios that ensure the formation of sufficient provisions to meet emergencies. The study also recommended that the macroeconomic policy should be based on creating a stable macroeconomic environment that allows the efficient employment of resources in all economic sectors in a way that achieves high economic growth rates, which contributes to the promotion of economic recovery and is reflected in income. Hence, individuals have a greater ability to repay loans.

This study aims to identify the role of organizational behavior and intellectual capital on risk management implementation and Village Credit Institutions (called LPD) performance. The LPD population is 1,256 units spread across nine districts/cities in Bali. This research was conducted at the LPD as the only microfinance institution based on local wisdom in traditional villages in Bali Province, Indonesia. Based on sampling using the Slovin method, there were 139 LPD as sampled in this study. The respondent in this study was the Head of the LPD. LPD performance measurement is using the balanced scorecard method that combines financial and non-financial aspects. This study also investigates risk management's role as a mediator in the relationship between organizational behavior and intellectual capital on the LPD performance. Methods of data collection using a survey. The questionnaire was given to 139 LPD chairman who was respondents in this survey. The data analysis technique used SEM-PLS. This study succeeded in confirming Resource-Based View Theory that organizational behavior and intellectual capital affect risk management and organization performance. These results also prove risk management's role as a mediation for the relationship between organizational behavior and intellectual capital on organizational performance.

This study focuses on the risk management of "Digital Goods" appeared with the progress of information technology(IT) in international transaction. As a result of that digital goods have a lot of uncertainty between the general goods or service which have been deal with object of international transaction broadly because digital goods hold uniqueness. In this study, the author give a definition of "Digital Goods" and make an examination of uniqueness of that in international transaction. Next, six risks are defined base on risk theory and risk analysis matrix applying risk mapping model is made. Conclusionally, risk transfer as insurance is adequate to manage business risk, security risk, credit risk and legal risk. Meanwhile, risk avoidance is adequate to manage reputation risk and market risk. But, this study have following three limits. Firstly, concerning definition of the risk, real case is not applied owing to lack of transaction data. Secondly, measuring of the risk is not based on absolute data but relative data. Lastly, suggesting way of risk management is not concrete and practical to international trader of digital goods.

Commercial banks and other related areas have developed internal models to better quantify their financial risks. Since an appropriate credit risk model plays a very important role in the risk management at financial institutions, it needs more accurate model which forecasts the credit losses, and statistical inference on that model is required. In this paper, we propose a new method for estimating a default rate. It is a Bayesian approach using the power prior which allows for incorporating of historical data to estimate the default rate. Inference on current data could be more reliable if there exist similar data based on previous studies. Ibrahim and Chen (2000) utilize these data to characterize the power prior. It allows for incorporating of historical data to estimate the parameters in the models. We demonstrate our methodologies with a real data set regarding SOHO data and also perform a simulation study.

We investigate interconnectedness and the contagion effect of default risk in Asian sovereign CDS markets since the global financial crisis. Using dynamic conditional correlation analysis, we find that there are significant co-movements in Asian sovereign CDS markets; that such co-movements tend to be larger between developing countries than between developed and developing countries; and that in the co-movements intra-regional nature is stronger than inter-regional nature. With the Spillover Index model, we measure contagion probabilities of sovereign default risk in CDS markets of seven Asian countries and find evidence of contagion effects among six of them; Japan is the exception. In addition, we find that these six countries are affected more by cross-market spillovers than by their own-market spillovers. Furthermore, a rolling-sample analysis reveals that contagion in the Asian sovereign CDS markets expands during episodes of extreme economic and financial distress, such as the Lehman Brothers bankruptcy, the European financial crisis, and the US-credit downgrade.
