Surging US Real Yields Push Bitcoin Below $84,000

Bitcoin recorded an intraday low of $83,500 on September 23, coinciding with the US 10-year Treasury yield closing at 5.11%, a rise of 15 basis points in a single session. This move was driven by a hotter-than-expected business activity survey, which prompted investors to reprice interest rates.

Bitcoin is currently trading within the $84,000 to $85,000 zone, which Glassnode identifies as its nearest on-chain support level.>

Real yields drove the majority of the move

The 10-year real yield, which excludes expected inflation, climbed from 2.63% to 2.76% along the Treasury curve. This increase accounted for 13 of the 15 basis points added to the nominal yield. Implied 10-year inflation compensation, the gap between nominal and real yields, edged up from approximately 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 does not generate its own yield.

The catalyst was 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, marking the strongest expansion in the survey since July 2021.

An economy expanding at this pace leaves the Federal Reserve with less room to ease monetary policy, just one week after its September 16 rate hike to a target range of 3.75% to 4.00%. Intraday reports placed the 10-year yield near 5.058% within minutes of the PMI release, and Treasury’s end-of-day curve settled at 5.11%.

Bitcoin’s decline occurred during the same session, with approximately $280 million in long liquidations as the price broke below $84,000, according to CoinGlass.

Glassnode’s map identifies support at $84,000 to $85,000

Glassnode’s September 23 report places the largest cluster of long-term holder supply between $84,000 and $85,000. This is the price range where the largest block of patient holders acquired their coins.

Bitcoin is also trading above the short-term holder cost basis and above the True Market Mean at $77,000. Glassnode describes this level as the main downside reference if the market loses the $84,000 support.

On the upside, the report identifies 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 approximately 8.6% lower, while the $96,700 level is about 14.7% higher. Glassnode’s framework relies on sustained trading beneath the supply zone, meaning daily closes carry significant weight in interpreting the September 23 dip.

An intraday wick through $84,000 leaves the market structure intact, whereas a series of closes below that level would bring the $77,000 reference into play.

Buyers returned before the bond market move

Glassnode’s demand data indicates that spot Bitcoin ETFs absorbed approximately $1.3 billion over the five days following the recent squeeze, ending two weeks of outflows.

Over the same period, 24-hour spot volume across exchanges increased by 121% from its August trough. Figures from Farside Investors show $999 million in ETF inflows on September 21, $714.7 million on September 22, and $346.9 million on September 23. IBIT led on the second day with $350.3 million, followed by FBTC at $257.4 million and MSBT at $99 million.

Glassnode’s on-chain and ETF observations primarily cover data through September 21, with spot-volume data extending to September 22. Farside’s September 23 figures show that inflows persisted during Wednesday’s bond selloff, albeit at a slower pace than on Tuesday.

Friday brings approximately $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 assumes the 10-year real yield retraces below approximately 2.65% while ETF inflows remain positive and spot volume expands on up days. Bitcoin maintains daily closes within the $84,000 to $85,000 zone, and buyers who returned last week absorb the macroeconomic hit.

Under this path, attention shifts from defending support toward the $95,000 to $97,000 region, with Glassnode’s $96,700 resistance serving as the test that would confirm the recovery has room to run.

The bear case involves real yields extending toward 2.85% to 2.90% as markets price in a longer period of restrictive Federal Reserve 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 subsequent rebound.

Bitcoin’s next few daily closes and the 10-year real yield’s subsequent moves will determine which of Glassnode’s two reference points—the $77,000 or the $96,700—the market reaches first.
