Public feeds

NY Fed Reverse Repo (RRP) daily take-up

newyorkfed.org/markets/omo/dmm/temp.html or FRED series RRPONTSYD

RRP balance draining vs rising signals system liquidity/excess cash sloshing toward bills, front-running QT/QE turning points and bill supply absorption capacity → SOFR, T-bill yields, front-end rates, USD liquidity regime

FREEdailyban:nonetA

Treasury General Account (TGA) daily balance

Treasury Daily Statement (fiscaldata.treasury.gov API, dataset 'Daily Treasury Statement')

TGA rebuild/drawdown mechanically adds or drains bank reserves, a direct plumbing input to repo rates and risk-asset liquidity → bank reserves, SOFR spikes, risk-on/off liquidity proxy

FREEdailyban:nonetA

SOFR vs IORB vs EFFR spread

newyorkfed.org/markets/reference-rates (SOFR), federalreserve.gov (IORB), FRED (EFFR, SOFR)

Widening SOFR-IORB spread is the classic 'reserves are getting scarce' early warning used before 2019 repo blowup and Sept 2019-style events → repo stress, front-end rate vol, bank reserve adequacy

FREEdailyban:nonetA

Treasury bill net issuance / auction calendar

treasurydirect.gov auction results API + fiscaldata.treasury.gov

Heavy bill supply drains RRP and money-fund cash, a mechanical predictor of front-end rate pressure independent of Fed policy → bill yields, RRP balances, MMF allocation shifts

FREEweeklyban:nonetA

Treasury coupon auction internals (bid-to-cover, indirect/direct bidder %, tail)

treasurydirect.gov/TA_WS/securities/auctioned (public JSON API)

Weak indirect bidder share / large tails on 10s/30s auctions are the cleanest real-time gauge of foreign demand fatigue for US debt, ahead of yield selloffs → UST 10y/30y yields, term premium, USD demand

FREEweeklyban:nonetA

USDT (Tether) supply changes across chains

Etherscan/Tronscan address for Tether Treasury (public, well-known wallets) + whale-alert.io RSS

Large fresh USDT mints to exchanges historically precede risk-on crypto buying pressure within 24-72h as it's typically pre-funding for purchases → BTC/ETH spot demand, crypto risk appetite

FREEdailyban:lowtB

USDC supply & Circle reserve composition

circle.com/en/usdc (transparency page) + Etherscan USDC contract totalSupply()

USDC mint/redeem is the cleanest institutional-flow proxy since Circle only mints on verified fiat wire receipt (unlike opaque offshore Tether issuance) → institutional crypto demand, stablecoin market share war (vs USDT)

FREEdailyban:nonetA

Exchange BTC/ETH net flow (onchain, self-computed)

blockchain.info/blockchain.com API + Etherscan API against a self-maintained labeled exchange-address list

Net inflows to exchanges precede sell pressure (coins moving to liquidate), net outflows signal accumulation/cold storage — classic onchain leading indicator → BTC/ETH spot price direction, short-term supply/demand

FREEdailyban:lowtB

Perp funding rates across exchanges (BTC/ETH)

Binance Futures public API (fapi.binance.com/fapi/v1/fundingRate), Bybit v5 API, OKX public API

Persistently positive/extreme funding = crowded leveraged longs vulnerable to long-squeeze; negative funding flags short crowding — mean-reverting positioning signal → BTC/ETH perp basis trades, liquidation cascade risk

LOCKEDintradayban:lowtA

Perp/futures open interest by exchange

Binance/Bybit/OKX/Deribit public REST APIs (openInterest endpoints), aggregated

OI rising with flat/falling price = building leverage divergence, historically precedes violent liquidation cascades in either direction → crypto volatility regime, liquidation risk

LOCKEDdailyban:lowtA

Spot Bitcoin/Ether ETF daily creation/redemption flows

Farside Investors (farside.co.uk/btc/ — free daily table) cross-checked against issuer daily holdings pages (blackrock.com, fidelity.com)

ETF flows are now a primary marginal-buyer proxy for BTC/ETH spot demand from TradFi allocators, directly moving price on large flow days → BTC/ETH spot price, GBTC-arb basis trades

PREMIUMdailyban:lowtB

Grayscale GBTC/ETHE premium/discount to NAV

ycharts free page or self-computed (GBTC price from any free quote API vs BTC spot × shares outstanding from grayscale.com holdings disclosure)

Discount/premium reflects arb-fund positioning and redemption pressure post-conversion-to-ETF; sharp moves flag basis-trade unwinds that spill into spot BTC selling → BTC spot basis, arb-fund flows

PREMIUMdailyban:lowtB

DeFi TVL by chain and protocol

DeFiLlama public API (api.llama.fi/charts, no key needed)

Chain-level TVL rotation (e.g. Solana share rising vs Ethereum) leads narrative-driven token rallies for that chain's ecosystem tokens before retail catches on → L1/L2 token relative performance, DeFi blue-chip tokens

FREEdailyban:nonetA

SPDR Gold/Silver Trust (GLD/SLV) daily share creation/redemption & bar list changes

spdrgoldshares.com (daily holdings XLS) and slvetf.com

GLD/SLV creation baskets require physical bar delivery to the trust; redemption spikes vs COMEX registered stock tightness flag physical-delivery stress (esp. relevant to any COMEX squeeze narrative) → gold/silver spot, COMEX futures basis, physical delivery squeezes

PREMIUMdailyban:nonetA

Whale Alert large stablecoin/BTC transaction feed

whale-alert.io public Twitter/RSS-style feed (also has a free-tier API)

Single large pre-exchange-deposit transactions from known cold-storage/whale wallets are a direct short-horizon sell-pressure tell, especially from dormant wallets waking up → BTC/ETH short-term price moves, whale distribution phases

FREEintradayban:lowtB

Treasury quarterly refunding announcement (QRA) coupon/bill mix

home.treasury.gov/policy-issues/financing-the-government/quarterly-refunding (press release + charts, quarterly)

Yellen/Bessent-style skew toward bills vs coupons is a direct, telegraphed supply signal that moves term premium and duration positioning before the auctions even happen → UST 10y/30y term premium, duration-sensitive trades
