Bitcoin Spot ETFs have experienced roller coaster inflows and outflows, primarily driven by investors who respond primarily to shifts in macroeconomic queues.
But following the US Federal Reserve’s decision not to change interest rates, a new wave of optimism wiped out the market. The move appears to have reassured investors and rekindled the institutional appetite for BTC-backed funds.
Bitcoin ETF bounces
The week started strong. Monday’s inflow totaled $425.45 million across the BTC spot ETF. However, the bullish momentum was suspended on Tuesday as institutional investors pulled capital from the market ahead of the Federal Open Market Committee (FOMC) meeting. The pullback brings net flow to $85.64 million.
However, the trend changed on Wednesday thanks to the Fed’s decision to hold interest rates. The announcement sparked a sharp rebound in investor confidence, driving a fresh inflow of $142.31 million into the BTC ETF.

No funds recorded net outflows on Wednesday, according to Sosovalue.
Options and futures control the Bitcoin Bulls
New optimism extends beyond the influx to ETFs. BTC has grown 2% over the past 24 hours and is currently trading at $98,888. This price surge is accompanied by a positive funding rate, indicating an increase in leveraged strengths.

However, it is important to note that despite this, open interest in BTC futures has declined by 0.18% over the past day. This suggests that traders are largely optimistic, but some leveraged positions may be closed to make a profit as BTC soars.
