The 12 months have been very difficult for ASX lithium stocks once again.

Over the period, the likes of Core Lithium Ltd (ASX: CXO), IGO Ltd (ASX: IGO), Liontown Resources Ltd (ASX: LTR), Mineral Resources Ltd (ASX: MIN), and Pilbara Minerals Ltd (ASX: PLS) have crashed deep into the red.

Here's a summary of how these shares have performed:

• The Core Lithium share price is down over 60%
• The IGO share price is down approximately 50%
• The Liontown share price is down over 50%
• The Mineral Resources share price is down 67%
• The Pilbara Minerals share price is down 54%

The catalyst for this has been weak lithium prices caused by a combination of oversupply of the white metal, softer than expected demand, and the emergence of low cost lepidolite in China.

This has weighed heavily on the financial performance of lithium miners. So much so, some companies have had to shut mines to conserve cash.

But is the worst over and will lithium prices rebound soon?

Let's look at what analysts at Goldman Sachs are forecasting for three widely used lithium types (lithium carbonate, lithium spodumene, and lithium hydroxide) through to 2028.

Recent lithium prices

In order to give you an understanding of how far lithium prices have fallen, let's start by looking at what lithium prices averaged during 2023 and 2024:

• Lithium hydroxide – China: 2023 US$32,452 per tonne, 2024 US$10,083 per tonne
• Spodumene 6%: 2023 US$3,712 per tonne, 2024 US$974 per tonne

Current spot prices

Now let's have a quick look at the current spot prices of these metals. They are as follows:

• Lithium carbonate – China: US$9,147 per tonne
• Lithium hydroxide – China: US$8,560 per tonne
• Spodumene 6%: US$815 per tonne
