Basel III and stress testing

by Guest Contributor 2 min read September 20, 2010

On September 12, 2010, the new Basel III rules were passed in Basel, Switzerland. These new rules aim to increase the liquidity of banks over the next decade, thereby mitigating the risk of bank failures and mergers that transpired during the recent financial crisis.

Currently, banks must maintain capital reserves of 4% on their balance sheet to account for enterprise risk. Starting January 1, 2013, banks will be required to progressively increase their capital reserves, known as tier 1 capital, to 4.5%. By the end of 2019, this reserve will need to be 6%.  Banks will also be required to keep an emergency reserve, or “conservation buffer,” of 2.5%.

What does this mean for banks? And, what are some tools that banks can use in assessing credit risk?

By increasing capital reserves, banks will be more stable in times of economic hardship. The conservation buffer is meant to help absorb losses during times of economic stress, which means banks will be in a better position to maintain economic progress in the most challenging economic circumstances.

The capital reserve designated by the Group of Governors and Heads of Supervision is the minimum requirement each bank will be held to. Each bank will need to assess their current risk levels, and run stress tests to ensure they are in a good financial position, and are able to sustain strong financial health during a failing economy. Stress tests should be run for different time intervals, which will allow lenders to assess future losses and to plan capital satisfactoriness accordingly.

This type of credit risk analysis is possible through applications such as Moody’s CreditCycle Plus, powered by Experian, that allow for stress testing, and profit and loss forecasting.  These applications will measure future performance of consumer credit portfolios under various economic scenarios, measured against industry benchmarks.

Used EV Growth Signals a New Phase of Consumer Purchasing Behavior

The electric vehicle (EV) revolution isn’t slowing down, it’s changing lanes. While recent conversations have seemingly focused on softening demand for new EVs, the used segment has been gaining momentum. According to Experian Automotive’s 2025 EV Year in Review Report, new retail individual EV registrations fell 35.9% year-over-year. Meanwhile, the used retail individual EV registrations grew 25.4% from a year ago. As affordability and growing model availability reshapes consumer behavior, buyers are increasingly turning to pre-owned EVs, which has shown an interesting market divergence that is redefining how consumers are adopting this segment and what it can mean for automakers, dealers, and the overall industry. Key players behind rising used EV demand Notably, Tesla accounted for over half (60.5%) of used retail individual EV registrations in 2025, followed by Chevrolet at 6.4% and Nissan (5.5%). Diving a bit deeper, Tesla made up the top three models of the used individual registrations last year, with the Model 3 coming in at 27.2%, Model Y at 21.7%, and Model S (6.6%). The Chevrolet Bolt EV followed at 4.8% and the Nissan Leaf was at 4%. Tesla’s position as the leading make in the used EV market is a natural extension of its long-standing dominance in new EV sales. The brand’s leadership over the years created a large fleet of vehicles that are now entering the pre-owned market. What the used EV boom means for automotive professionals The growing demand for used EVs can present more opportunities for automotive professionals. Dealers that provide a healthy supply of pre-owned EVs can increase accessibility and play a role in adoption for consumers who are actively looking to purchase, while marketers can emphasize value and ownership benefits. As the market continues to evolve, automotive professionals who understand and respond to these changing dynamics will be best positioned to capitalize on the expanding pool of used EV shoppers.
