Bitcoin closes above $80,000 as US inflation data and yen interventions draw attention

Bitcoin closes above $80,000 amid US inflation and yen moves

Bitcoin recorded its first weekly close above $80,000 since early May. The price rise happened while investors waited for U.S. inflation numbers and as Japan announced a record intervention in the yen.

Key facts

• U.S. Consumer Price Index (CPI) and Producer Price Index (PPI) are due Thursday and Friday.
• Markets price a 0.25% Federal Reserve rate hike on Sept. 16 with 58.4% odds.
• Japan’s Ministry of Finance said foreign reserves fell $79.57 billion after a large yen intervention that lifted the yen to 155 per dollar.
• Analysts believe Japan likely sold U.S. Treasury securities to fund the intervention.
• Bitcoin’s supertrend indicator gave its first “buy” signal since late 2025.
• Derivatives open interest rose $2.3 billion on Sept. 3, while spot‑market demand stayed weak.

Japan ministry data

The Ministry of Finance reported that its foreign‑reserve assets dropped by $79.57 billion at the end of July. The yen strengthened to about 155 per U.S. dollar during Asian trading.

Market analysis

Fed officials said the CPI and PPI numbers alone do not justify a policy change. The Fed’s “preferred” inflation gauge, the Personal Consumption Expenditures index, still shows modest progress.

Bloomberg quoted Itochu Research chief economist Atsushi Takeda, who said Japan most likely sold U.S. Treasuries to finance the yen support.

CryptoQuant noted that the recent price rise was driven mainly by futures traders. Open interest on derivatives rose 9.2% in a single session, but spot‑chain participation lagged.

Confirmed details

• Bitcoin closed the week above $80,000.
• U.S. CPI for August was 0.1% month‑on‑month and 3.4% year‑on‑year.
• Japan’s foreign reserves fell $79.57 billion after the yen intervention.
• Derivatives open interest increased by $2.3 billion on Sept. 3.

Uncertainties

• It is not confirmed how much of the yen support was financed by selling U.S. Treasuries.
• Future spot‑market demand for Bitcoin remains unclear.
• The exact impact of the upcoming CPI/PPI releases on Bitcoin price is uncertain.

Implications

US inflation data and the Fed’s rate decision influence borrowing costs, which affect risk assets like Bitcoin. A large yen intervention can shift capital flows and affect the yen‑carry trade, which also moves Bitcoin.

Upcoming events

• U.S. CPI data on Thursday.
• U.S. PPI data on Friday.
• Federal Reserve policy meeting on Sept. 16.
• Potential Bank of Japan rate hike, with markets pricing a 0.25% increase.
