The vehicle depreciation rate will reach 17.8% in 2017 on 17 million new-vehicle sales, slightly higher than the 17.3% mark recorded in 2016, according to latest forecast from Black Book and Fitch Ratings. Prior to the Great recession, annual depreciation trended between 16% and 18%.

Between 2011 and 2016, average annual depreciation fell between 8.3% and 13.2%, driven mostly by low supply of in-demand pre-owned vehicle segments like trucks, crossovers and sport utility vehicles. Black Book added that it believes must of the pent-up demand that drove new- and used-vehicle sales has been spent, resulting in a rising level of vehicle depreciation expected in 2017.

“What’s more, a continued increase in lease activity along with higher incentives that began in 2016 spell more pressure on residual values, which are also expected to continue falling in 2017,” the firm stated.

The Black Book Wholesale Value Index, which is designed to provide an accurate view of the strength of used-vehicle wholesale market values, is expected to continue its slow decline in 2017 as the used-vehicle market loses strength, the firm said. In 2016, the index fell 6%.

Black Book forecasts a continual and gradual decline in residuals in the coming years. Currently, a two-year-old vehicle is averaging 52% of its original MSRP, and this is expected to decline to 48% by 2020. Black Book expects the market to reach a gradual normalization over the next three years. The biggest concerns include continuously increasing lease penetration leading to residual losses on the returns due to excess supply, higher levels of incentives on new vehicles pushing down used values, and longer loan terms leading to sustained negative equity.

“As we continue to move into the new year, several trends will continue to evolve and reshape the landscape for used vehicles,” said Anil Goyal, senior vice president of automotive valuation and analytics at Black Book. “Increased supplies from trade-ins and lease returns, coupled with a plateau in new sales activity will bring changes that can affect inventory strategies and profit potential.”

Fitch also offered its take on U.S. auto loan asset-back securities (ABS), noting that it doesn’t have major concerns despite expected weaker asset performance. “Fitch continues to have a positive rating outlook for prime auto loan asset-backed securities in 2017, despite higher losses expected this year,” said Hylton Heard, senior director of Fitch Ratings. “Auto ABS asset performance will continue to slow in 2017 as losses slowly rise to normalized levels similar to 2004-2006. Additionally, depreciation rates will creep up and recovery rates dip, which will drive loss severity and contribute to rising losses.

Fitch expects prime auto ABS annualized loss rates to move up to the 1% late in the year, but remain well within historical levels despite these negative trends. The historical average for the index is 0.91% going back to 2000, so current levels in early 2017 (December 2016: 0.73%) are comfortably tracking within our expectations.

Subprime auto ABS performance is pressured in 2017 due to softer performance in the 2013-2015 vintage securitizations, which have weaker credit quality pools. Fitch’s outlook for subprime asset performance is “weakening/stable” for 2017. “Our subprime annualized net loss index is predicted to range between 10%-12% during 2017, and could rise to peak levels recorded back in 2008-2009 of approximately 13%.”

Through January 2017, the ANL index stood at 10.3%.
