Price Action

In last weeks update we stated we were bullish BTC and that we expected it to rally off the 128-day moving average. That is exactly what has happened over the past week with BTC up +4.83%.

BTC price has continued to push away from the 128 day moving average, a critical moving average in Bitcoin bull markets and is making its way back up towards $120,000.

In addition, price has also bounced off the Short Term Holder Realized price, another key area of support in Bitcoin bull markets.

The STH Realized Price acts as a broad area of support for BTC price in bull markets. It appears to be doing the same again right now. You can learn more about this important onchain metric here.

We expect initial resistance for BTC to appear ahead of the previous all-time-highs at around $120,000.

The Big Story: Big Week For Bitcoin ETFs

U.S. spot Bitcoin ETFs are seeing their strongest inflows in months as traders position ahead of the Federal Reserve’s September 17 meeting. The major Bitcoin ETF funds pulled in more than $2.3 billion over the past week, marking five straight days of positive flows.

Daily inflows have been striking: $741 million on September 10, $552 million on September 11, and $642 million on September 12. 

Fidelity’s FBTC and BlackRock’s IBIT remain the top magnets for capital, with Fidelity alone drawing $315 million on Friday last week.

Bitcoin’s price has rebounded above $115,000, boosted by expectations that the Fed will ease policy. A Reuters survey showed nearly all economists expect a 25 basis point rate cut, with more reductions likely before year-end. Recent soft inflation data, including an unexpected drop in producer prices, has strengthened the case for looser monetary conditions.

Lower rates typically benefit risk assets, and ETFs are increasingly seen as the easiest on-ramp for pensions, hedge funds, and asset managers to gain exposure to Bitcoin. The strong inflows suggest Bitcoin is becoming a mainstream portfolio allocation, not just a speculative trade.

This can be seen in the cumulative inflows into the Bitcoin ETFs since their inception with BlackRock’s IBIT (yellow section of the chart) dominating the cumulative inflows.

With liquidity set to improve and institutions stepping up allocations, we see this latest wave as a foundation for potential new highs in Bitcoin later this year.

Buckle up, and we’ll be back with more insights as the Fed decision unfolds.
