The FRTB revisions address deficiencies relating to the existing [8] Standardised approach and Internal models approach [9] and particularly revisit the following: . The boundary between the "trading book" and the "banking book": [10] i.e. assets intended for active trading; as opposed to assets expected to be held to maturity, usually customer loans, and deposits from retail and corporate ...
Because of its two-step aggregation, capital allocation between trading desks (or even asset classes) is challenging; thus making it difficult to fairly calculate each desk's risk-adjusted return on capital. Various methods are then proposed here. [3]
Basel III requires banks to have a minimum CET1 ratio (Common Tier 1 capital divided by risk-weighted assets (RWAs)) at all times of: . 4.5%; Plus: A mandatory "capital conservation buffer" or "stress capital buffer requirement", equivalent to at least 2.5% of risk-weighted assets, but could be higher based on results from stress tests, as determined by national regulators.
These cases belong to (are a subset of) row 1 in the profit table, which have a profit of −100 (total loss of the 100 invested). The expected profit for these cases is −100. Now consider the calculation of , the expectation in the worst 20 out of 100 cases. These cases are as follows: 10 cases from row one, and 10 cases from row two (note ...
In mathematical finance, the SABR model is a stochastic volatility model, which attempts to capture the volatility smile in derivatives markets. The name stands for "stochastic alpha, beta, rho", referring to the parameters of the model.
Basel III: Finalising post-crisis reforms, sometimes called the Basel III Endgame in the United States, [1] [2] Basel 3.1 in the United Kingdom, [3] or CRR3 in the European Union, [4] are additional changes to international standards for bank capital requirements that were agreed by the Basel Committee on Banking Supervision (BCBS) in 2017 as part of Basel III, first published in 2010.

The aim is to protect the firms themselves, their customers, the government (which is liable for the cost of deposit insurance in the event of a bank failure) and the economy, by establishing rules to make sure that these institutions hold enough capital to ensure continuation of a safe ...
The simplest example given by Thimbleby of a possible problem when using an immediate-execution calculator is 4 × (−5). As a written formula the value of this is −20 because the minus sign is intended to indicate a negative number, rather than a subtraction, and this is the way that it would be interpreted by a formula calculator.
