Notable indictors such as wholesale values and conversion rates show that auction landscape is “very stable” after the first month of the year, according to Black Book’s newest installment of Market Insights released on Tuesday.

But changes could be arriving soon.

“The market continued to be very stable last week with depreciation following a normal seasonal pattern,” Black Book said in the report. “However, the main focus is now on the effects of tariffs on the automotive industry. We will be closely monitoring the impact this week on the used-car market.”

Implications from President Trump’s tariff decisions will arrive as overall wholesale prices softened by 0.34%, according to Black Book tracking.

Analysts also noticed last week’s auction conversion rate was 58%, pushing the average auction conversion rate for January to 57%.

Black Book said the recent conversion rate reading marked, “a strong start to the year. All indicators suggest that this trend will continue in the coming months.”

Analysts noticed that the depreciation of subcompact cars accelerated, with values sliding by 0.87%. That’s up from the previous week’s decline of 0.34%.

Black Book indicated subcompact cars have averaged a weekly decline of 0.86% since the beginning of the year.

Analysts watched trends for premium sporty cars moved in varied directions depending on the unit’s age. Black Book spotted a value decline of 0.77% for units less than 2 years old, while prices for these units between 2 and 8 years old increased 0.26%.

And prices for premium sporty cars more than 8 years old ticked 0.13% lower, according to Black Book.

In the truck department, analysts mentioned a couple of other segment movements that might be of interest to dealers and consignors.

After eight weeks of averaging a weekly decline of 0.89%, Black Book said minivans demonstrated signs of slowing depreciation last week, dropping by 0.47% and marking the segment’s lowest weekly decline since late November.

And analysts said full-size truck depreciation is stabilizing. Black Book said last week’s value decline of 0.18% for full-size trucks represented the smallest weekly decrease since the final week of October.

Whether it’s tariffs, trucks, cars or SUVs, Black Book reiterated, “As always, our team of analysts are focused on keeping their eyes on the market for developing trends and gathering insight.”
