Macro & Institutional News
Treasury yields reach multi-year highs
The U.S. bond market experienced another sharp repricing during the final days of September.
The benchmark 10-year Treasury yield climbed to 5.293% on September 29, its highest level since June 2007. The 30-year yield reached 5.6206%, its highest since June 2002.
Two-year U.S. yields have risen almost 60 bp during September and are heading toward their largest monthly increase since early 2023. Rising energy costs and persistent inflation concerns have reinforced expectations that interest rates may remain elevated for longer.
Higher long-term yields have become an important headwind for Bitcoin and other risk assets entering October.
Fed officials cool expectations for an immediate second hike
New York Fed President John Williams said on September 29 that policymakers have time to evaluate incoming economic data before raising rates again.
Williams said one additional increase may be appropriate later this year. Following his comments, traders reduced expectations for an October hike from almost 70% to around 50%. Markets shifted toward a single additional rate increase by year-end.
The next major signals will come from U.S. PCE inflation and employment data.
Energy and inflation remain central macro risks
Global sovereign bond markets are heading toward one of their weakest months in years as elevated energy costs continue feeding inflation expectations.
Oil prices retreated on September 29 following recent gains, providing some relief to shorter-term rate expectations. Long-duration yields remained close to multi-decade highs.
Market Trends & Institutional Flows
Bitcoin ETF inflows remain positive as daily momentum slows
U.S. spot Bitcoin ETFs continued attracting capital during the latest reporting period.
Reported net flows included:
- September 23: +$346.9M
- September 24: +$190.7M
- September 25: +$134.5M
- September 28: +$31.07M
Combined inflows reached approximately $703M.
The September 28 session extended the ETF inflow streak to eight consecutive trading days. The daily figure was also the weakest of the streak, indicating that institutional buying remained positive with a slower pace into month-end.
Over the previous 30 days, U.S. spot Bitcoin ETFs accumulated approximately $2.95B.
Bitcoin consolidates after the September breakout
Bitcoin traded around $83.6K–$83.9K on September 29 after reaching above $87K earlier in the month.
BTC is still on track for a quarterly gain exceeding 40%, its strongest quarterly performance since the final quarter of 2024.
The recent pullback has developed alongside rising Treasury yields and renewed macro uncertainty. The $84K–$85K region has also emerged as an important resistance area following the September rally.
Strategy adds another 1,665 BTC
Strategy disclosed another Bitcoin purchase during the week.
The company acquired 1,665 BTC for approximately $142.7M at an average price of $85,681 per Bitcoin. The transaction marked its second consecutive week of BTC purchases.
Its total Bitcoin position has subsequently increased to more than 847,000 BTC, reinforcing continued corporate demand even as BTC consolidates below its September high.
Options & Volatility Spotlight
October becomes the center of Coincall positioning
Coincall recorded $235.32M in total options trading volume during September 21–27.
RFQ contributed $74.63M, representing 31.71% of total options activity.
The October 30 expiry led the curve with $47.53M in volume, followed closely by October 9 with $45.70M. Together, the two October expiries generated more than $93M and accounted for almost 40% of weekly activity.
The 86K BTC strike leads
The 86K BTC strike generated $22.40M in trading volume and became the most active strike of the week.
The 83K strike followed with $15.73M, and 88K generated $14.62M. Activity therefore formed a clear concentration around the 83K–88K region.
The 73K and 75K strikes also generated substantial volume, showing continued positioning across lower BTC levels.
Options selling takes a narrow lead
Call-side taker flow accounted for 51.61% of weekly activity.
Sell calls were the largest individual category at 27.32%, followed by sell puts at 24.93%, buy calls at 24.29% and buy puts at 23.46%.
The close distribution across the four categories points to broad participation as traders reposition from September contracts into October and November maturities.

Upcoming Catalysts to Watch
U.S. PCE inflation
Markets are waiting for the next PCE inflation reading following September's sharp repricing in Treasury yields.
A stronger inflation reading could revive expectations for an October rate increase. Softer data could reinforce John Williams' message that the Fed has time before taking additional action.
U.S. employment data
The monthly U.S. jobs report arrives later this week and will provide another major input into the Fed's next decision.
Employment resilience combined with persistent inflation would strengthen the case for another hike later in 2026.
Bitcoin is in $84K–$88K region
Bitcoin has pulled back from its September high above $87K and is consolidating around $84K.
Coincall options activity is concentrated around 83K, 86K and 88K, making the same region particularly relevant for derivatives positioning entering October.
ETF flow durability
Bitcoin ETFs have extended their positive sequence to eight trading sessions, though daily inflows fell to only $31.07M on September 28.
A renewed acceleration would strengthen institutional support beneath BTC. Continued deceleration would remove one of the major forces behind September's recovery.
Looking Ahead — Bitcoin Enters October With $84K in Focus
Bitcoin finishes September in a stronger position than it started the quarter.
BTC remains on course for a quarterly gain exceeding 40%, supported by renewed institutional ETF demand and a recovery that briefly carried the market above $87K.
The immediate environment is becoming more challenging. Long-term Treasury yields have reached levels unseen in almost two decades, energy-driven inflation remains a concern and markets are preparing for another round of important U.S. inflation and employment data.
ETF demand remains positive, with approximately $703M entering Bitcoin funds across September 23–28. The latest daily inflow slowed to $31.07M, making flow momentum an important indicator entering October.
Bitcoin's ability to reclaim the upper-$80K region, ETF flow persistence and the next round of U.S. macro data will define the opening stage of October.
