Crypto investors woke today to the realisation that so-called stablecoins are not so stable at all.
This comes as TerraUSD (CRYPTO: UST) – intended to be pegged to the US dollar – plunged to an all-time low of 30 US cents overnight.
In a sign of the ongoing volatility in crypto markets, including within the stablecoin subsector, UST has rebounded from those lows and is currently worth 81 US cents.
Whether it will hold there, return to its intended peg of US$1, or plunge back to new lows is anyone's guess at this stage.
'Stabilising' crypto loses 97% of its value
The even bigger carnage happened to the crypto that's intended to keep UST in line with the US dollar. Or stable, in other words.
Terra (CRYPTO: LUNA) plunged 97% overnight, dropping to US$1.04. LUNA traded for as high as $19.17 over the course of the day. At the time of writing, LUNA has edged higher to US$1.05, down 94% from this time yesterday.
So, what's going on?
Why the massive sell-off?
If you're not familiar with LUNA, CoinMarketCap explains that: "Terra's native token, LUNA, is used to stabilise the price of the protocol's stablecoins."
Those stablecoins are UST.
Some stablecoins are backed by the asset they're pegged to, like US dollars. Some are backed by other cryptos like Bitcoin (CRYPTO: BTC) and Ethereum (CRYPTO: ETH).
Still others, like Terra's UST, use algorithms to maintain their pegs. UST attempted to do this by enabling crypto investors holding its stablecoin to swap it for US$1 worth of LUNA at any stage.
That was meant to keep UST trading within a close range of the US dollar, as any dip below that could be regained by moving into LUNA.
However, the system ultimately relies on crypto investor confidence. And that confidence looks to have gone missing.
According to analysts at Coinbase (quoted by Markets Insider): "The exact reason UST became untethered from the dollar remains unclear, but on Saturday, hundreds of millions of dollars' worth of both UST and LUNA were rapidly sold across exchanges, pushing UST to around 98 cents." Not long after that, they said, "panic set in".
Commenting on the meltdown at Terra, Nikita Fadeev, head of crypto fund Fasanara Digital, said (courtesy of Bloomberg):
Many people were caught off guard. Everything broke there. It is full capitulation … It will get worse before it will get better. Way too much UST is looking to exit, and the death spiral is very reflexive at these levels. It's a long road ahead.
"Once liquidity evaporated, this perpetuated the collapse of the stablecoin," Clara Medalie, research director at Kaiko, added.
Do Kwon, the billionaire crypto investor whose Terraform Labs developed UST and LUNA, tried to stem the sell-off by issuing US$1.5 billion of loans in UST and Bitcoin.
But Bryn Solomon from crypto trading platform Mgnr.io doesn't believe there will be many takers.
"At this stage, I don't think these firms will have the risk appetite to support it," he said. "Algorithmic stables are a confidence game. Once confidence is lost, it's game over."
