Bitcoin registered an intraday low at $83,500 on Sept. 23, the same day the US 10-year Treasury yield closed at 5.11%, up 15 basis points in a single session, as a hotter-than-expected business activity survey pushed investors to reprice interest rates.
Bitcoin now sits inside the $84,000 to $85,000 zone Glassnode identifies as its nearest on-chain support.
Real yields carried most of the move
The 10-year real yield, which strips out expected inflation, climbed from 2.63% to 2.76% on Treasury's curve, accounting for 13 of the 15 basis points added to the nominal yield. Implied 10-year inflation compensation, the gap between the two, edged from about 2.33% to 2.35%.
| Metric | Sept. 22 | Sept. 23 | One-day move | Why it matters for Bitcoin |
|---|---|---|---|---|
| 10-year Treasury yield | 4.96% | 5.11% | +15 bps | Raises the benchmark return available in government debt |
| 10-year real yield | 2.63% | 2.76% | +13 bps | Increases the inflation-adjusted opportunity cost of holding BTC |
| Implied inflation compensation | 2.33% | 2.35% | +2 bps | Shows the move was mostly real-rate driven |
| S&P Global composite PMI | 56.0 | 58.4 | +2.4 pts | Triggered the repricing by showing stronger business activity |
Investors demanded a higher inflation-adjusted return on government debt, which raises the opportunity cost of holding Bitcoin, an asset that pays no yield of its own.
The trigger came from S&P Global's September Purchasing Managers' Index. The composite reading jumped to 58.4 from 56.0, with services at 58.7 and manufacturing at 57.0, the strongest expansion in the survey since July 2021.
An economy running that hot leaves the Federal Reserve less room to ease, one week on from its Sept. 16 hike to a 3.75% to 4.00% target range. Intraday reports put the 10-year near 5.058% within minutes of the PMI release, and Treasury's end-of-day curve settled at 5.11%.
Bitcoin's decline played out in the same session, with roughly $280 million in long liquidations as price broke below $84,000, according to CoinGlass.
Glassnode's map puts support at $84,000 to $85,000
Glassnode's Sept. 23 report places the largest cluster of long-term holder supply between $84,000 and $85,000, the price range where the biggest block of patient holders acquired their coins.
Bitcoin also trades above the short-term holder cost basis and above the True Market Mean at $77,000, which Glassnode describes as the main downside reference if the market loses $84,000.
On the upside, the report puts the next major resistance at $96,700, derived from the mean MVRV price.
| Level | Glassnode marker | Distance from ~$84,282 | Editorial meaning |
|---|---|---|---|
| $77,000 | True Market Mean | -8.6% | Main downside reference if $84K fails |
| $84,000–$85,000 | Long-term holder supply cluster | Current zone | Nearest support and key daily-close battleground |
| $96,700 | Mean MVRV resistance | +14.7% | Upside test if buyers absorb the macro shock |
From the current quote near $84,282, the $77,000 level sits about 8.6% lower and the $96,700 level about 14.7% higher. Glassnode's framework rests on sustained trading beneath the supply zone, so daily closes carry the weight in reading the Sept. 23 dip.
An intraday wick through $84,000 leaves the structure intact, while a run of closes below it would bring the $77,000 reference into play.
The buyers who returned before the bond move
Glassnode's demand data shows spot Bitcoin ETFs took in about $1.3 billion over the five days since the recent squeeze began, ending two weeks of outflows.
Over the same stretch, 24-hour spot volume across exchanges climbed 121% from its August trough. Farside Investors' figures show $999 million of ETF inflows on Sept. 21 and $714.7 million on Sept. 22 and $346.9 million on Sept. 23. IBIT led the second day with $350.3 million, with FBTC at $257.4 million and MSBT at $99 million.
Glassnode’s on-chain and ETF observations run mostly through Sept. 21, and its spot-volume data through Sept. 22. Farside’s Sept. 23 figures show inflows persisted during Wednesday’s bond selloff, though at a slower pace than Tuesday.
Friday brings roughly $16 billion in Bitcoin options expiring on Deribit, US durable goods and consumer sentiment data a few hours later, and CME's September Bitcoin futures settlement in the afternoon.
Whether $84,000 holds or $77,000 comes into view
The bull case has the 10-year real yield retracing below roughly 2.65% while ETF inflows stay positive and spot volume expands on up days. Bitcoin holds daily closes inside the $84,000 to $85,000 zone, and buyers who returned last week absorb the macro hit.
Under that path, attention moves from defending support toward the $95,000 to $97,000 region, with Glassnode's $96,700 resistance as the test that would confirm the recovery has room to run.
The bear case has real yields extending toward 2.85% to 2.90% as markets price a longer stretch of restrictive Fed policy. Bitcoin loses the $84,000 to $85,000 zone on sustained daily closes while ETF flows slow or turn negative.
| Scenario | Real-yield signal | BTC price signal | ETF / spot demand signal | Next level in focus |
|---|---|---|---|---|
| Bull case | 10-year real yield retraces below ~2.65% | Daily closes hold $84K–$85K | ETF inflows stay positive; spot volume rises on up days | $96,700 |
| Bear case | 10-year real yield extends toward 2.85%–2.90% | BTC loses $84K–$85K on sustained closes | ETF flows slow or turn negative; spot volume rises on selloffs | $77,000 |
In that scenario, the $77,000 True Market Mean becomes the active downside reference, and the long-term holders clustered at $84,000 turn into overhead supply for any rebound that follows.
Bitcoin's next few daily closes and the 10-year real yield's next moves will decide which of Glassnode's two reference points, $77,000 or $96,700, the market reaches first.
