The Internal Ratings Based (IRB) approach for capital determination is one of the cornerstones in the proposed revision of the Basel Committee rules for bank regulation. We evaluate the IRB approach using historical business loan portfolio data from a major Swedish bank for the period 1994 to...

A drawback of available portfolio credit risk models is that they fail to allow for default risk dependency across loans other than through common risk factors. Thereby, thesemodels ignore that close ties can exist between companies due to legal, financial and business relations. In this paper,...

In 2015, 70% of newly-issued leveraged loans had weaker enforcement features, called covenant-light or "cov-lite;" this is nearly a three-time increase in cov-lite issuance compared to a previous peak in 2007. We evaluate whether this development can be attributed to market overheating, increased...

A string of theoretical papers shows that the non-exclusivity of credit contracts generates important negative contractual externalities. Employing a unique dataset, we identify how these externalities affect the supply of credit. Using internal information on a creditor's willingness to lend,...

On December 16th of 2015, the Fed initiated "liftoff," raising the federal funds rate range by 25 basis points and ending a 7-year regime of near-zero rates. We use a unique dataset of 640,000 loan-hour observations to measure the impact of liftoff on interest rates in the peer-to-peer lending...

On December 16th of 2015, the Fed initiated "liftoff", a critical step in the monetary normalization process. We use a unique panel dataset of 640,000 loan-hour observations to measure the impact of liftoff on interest rates, demand, and supply in the online primary market for uncollateralized...

Commercial-paper backup lines account for a substantial share of undrawn loan commitments in the corporate sector, but have despite this received scant attention in the credit-line literature. In this paper, I study the liquidity-insurance properties of backup lines using a comprehensive loan-...

Counterpart risk rating is at the heart of the banking business. In the new Basel II regulation, internal ratings have been given a central role. Although much research has been done on external ratings, much less is known about banks´ internal ratings. This paper presents new quantitative...

Does the Church Tower Principle, i.e. geographical proximity between borrowing firm and lending bank, matter in credit risk management? If so, the bank might expose itself to a greater risk by lending to distant firms and should therefore respond by rationing them harder. In this paper we...
