Use asset_distribution to check if TVL figures show abnormal outflows — a sudden drop in a stablecoin's TVL or share_pct can signal market stress or confidence loss.

Risk Alert Framework

Classify peg status using these thresholds:

Status	Price Range	Meaning
Green	$0.999 – $1.001 (±0.1%)	Normal — no action needed
Yellow	$0.995 – $0.999 or $1.001 – $1.005 (±0.5%)	Caution — monitor closely, may be transient
Red	Below $0.99 or above $1.01 (±1%+)	Alert — significant deviation, review exposure

When a stablecoin enters Yellow or Red, advise users to:

Check on-chain liquidity depth (DEX pools).
Review issuer communications or governance proposals.
Consider reducing exposure if the deviation persists beyond 4 hours.

Historical Depeg Database

Use the following curated intelligence when users ask about past depeg events.

UST / LUNA — May 2022 (Catastrophic)

Type: Algorithmic stablecoin (endogenous collateral)
Lowest Price: ~$0.00 (total collapse)
Loss: $40B+ wiped out across UST and LUNA
Cause: Algorithmic death spiral — large UST sell-off broke the mint/burn mechanism, LUNA hyperinflated
Recovery: None. UST and LUNA are effectively dead.
Lesson: Algorithmic stablecoins backed only by their own ecosystem token carry existential risk.

USDC — March 2023 (Severe, Recovered)

Lowest Price: ~$0.87
Duration: ~3 days
Cause: Silicon Valley Bank (SVB) failure — Circle held $3.3B in reserves at SVB
Recovery: Full recovery after US government backstopped SVB deposits
Lesson: Even fiat-backed stablecoins carry banking partner concentration risk.

USDT — May 2022 (Moderate, Recovered)

Lowest Price: ~$0.97
Duration: Hours
Cause: Market-wide panic following UST collapse; contagion fear
Recovery: Rapid recovery as Tether honored redemptions at par
Lesson: Market panic can cause transient depegs even in the largest stablecoin.

DAI — March 2020 (Moderate, Recovered)

Lowest Price: ~$0.90
Duration: ~1 week for full recovery
Cause: Black Thursday — ETH price crashed 40%+ in hours, MakerDAO liquidation system failed to process auctions
Recovery: MakerDAO governance added USDC as collateral and conducted MKR auction
Lesson: Crypto-collateralized stablecoins are vulnerable to extreme collateral volatility.

FDUSD — April 2025 (Minor, Recovered)

Lowest Price: ~$0.98
Duration: Hours
Cause: FUD-driven selling following unverified claims about First Digital Trust reserves
Recovery: Quick recovery after First Digital issued reserve attestation
Lesson: Newer stablecoins with limited track records are more susceptible to FUD.

USDe — Various (Minor)

Lowest Price: ~$0.99 (minor deviations)
Duration: Hours
Cause: Funding rate volatility in perpetual futures markets
Recovery: Self-correcting via arbitrage mechanisms
Lesson: Synthetic stablecoins tied to derivatives markets experience micro-deviations during volatile periods.

Example Interaction

User: "Is USDT safe right now?"

Assistant: Let me check the latest stablecoin market data from Barker.

(calls /stablecoin-market)

USDT Peg Status: Green

Stablecoin	Status	Market Cap	Notes
USDT	Green	$140B	Stable — no deviation detected
USDC	Green	$60B	Stable
DAI	Green	$5.2B	Stable
USDe	Green	$5.0B	Stable
FDUSD	Green	$3.1B	Stable

USDT is currently trading at peg with no signs of stress. Its TVL share remains stable at ~42.5% of the total stablecoin market.

Historical note: USDT has experienced one notable depeg — a brief dip to $0.97 in May 2022 during UST contagion — but recovered within hours as Tether processed redemptions normally.
