Bitcoin (BTC) continues to weaken, sliding to the $82,000 range. Rather than any idiosyncratic bad news within the crypto market, the downturn is being driven by a combination of rising international oil prices, surging U.S. Treasury yields, and the possibility of additional tightening by the Federal Reserve (Fed), all pressuring risk assets simultaneously.

■ Altcoins fall as well On the 28th (local time), Bitcoin briefly dropped below $83,000. That day, not only Bitcoin but also major altcoins such as Dogecoin (DOGE) and Solana (SOL) declined together, showing risk-averse movements across the crypto market.

■ Oil in the $107 range stokes inflation fears The first factor to note in this decline is international oil prices. Brent crude rose to $107.29 per barrel on the 28th, up about 2.84% from the previous trading day ($104.32). With tensions surrounding the United States and Iran continuing and uncertainty over the reopening of the Strait of Hormuz unresolved, geopolitical risk is once again being priced into the oil market.

While rising oil prices may seem unrelated to the crypto market, they can affect Bitcoin through prices and interest rates in financial markets. If energy price increases persist, inflationary pressure in the U.S. could strengthen again, which would reduce the likelihood of monetary easing by the Fed.

■ Fed may still hike further this year Indeed, at its Federal Open Market Committee (FOMC) meeting on the 16th, the Fed raised its benchmark rate by 0.25 percentage points to a range of 3.75–4.00%. The Fed said at the time that U.S. economic activity was expanding at a solid pace while inflation remained elevated.

The possibility of further rate hikes remains. The Fed officials' projections indicated expectations of one more hike this year, and St. Louis Fed President Alberto Musalem also suggested that additional rate increases may be needed to contain persistent inflation.

■ Treasury yields top 5%, denting Bitcoin's relative appeal In this process, rising U.S. Treasury yields pose another burden for Bitcoin. When yields on interest-bearing assets like Treasuries exceed 5%, the relative investment appeal of Bitcoin—which pays no interest and is highly volatile—can diminish. In particular, high rates worsen funding conditions for market participants using leverage.

The recent trend should be understood as a chain: rising oil prices → inflation fears → possibility of additional Fed tightening → rising Treasury yields → pressure on risk assets. The fact that selling pressure emerged across crypto assets as oil prices and Treasury yields rose simultaneously shows that Bitcoin is behaving more like a high-risk asset than a traditional safe-haven asset like gold.

■ Spot ETF inflows act as a buffer However, there are factors that could partially cushion Bitcoin's downside. Money has recently flowed back into U.S. spot Bitcoin ETFs. According to aggregated data, these ETFs saw net inflows of about $2.84 billion over six consecutive trading days from September 17 to 24. Although cumulative net outflows had exceeded $5 billion at one point this year, the recent inflows turned the annual cumulative flow back to positive.

■ Key indicators to watch Ultimately, judging Bitcoin's next direction cannot be based solely on the $82,000 price level. Key variables include: whether international oil prices remain high above $100; whether U.S. Treasury yields rise further from around 5%; and whether upcoming U.S. inflation and employment data strengthen or weaken expectations of additional Fed rate hikes. In addition, crypto-specific supply and demand factors—such as spot Bitcoin ETF flows, open interest in the futures market, and funding rates—should also be monitored.

The core issue in the current market is not Bitcoin alone, but changes in the macro environment. If high oil prices and elevated Treasury yields persist simultaneously, pressure on risk assets is likely to continue. Conversely, if inflationary pressure eases and Treasury yields stabilize, the impact of recently inflowed ETF money on Bitcoin's supply and demand could once again become important.
