What is UK inflation July 2025 and how was it measured?

UK inflation July 2025 refers to the Consumer Prices Index (CPI) annual rate, which rose to 3.8%, the highest in 19 months. The Office for National Statistics measures CPI by tracking price changes for a basket of goods and services month-on-month and comparing year-on-year levels.

How will UK inflation affect cryptocurrencies like BTC and ETH?

The jump to 3.8% CPI increases the probability of tighter monetary policy over coming months, which historically pressures risk assets including cryptocurrencies. Higher real yields or a hawkish stance from the Bank of England can reduce liquidity and trigger short-term selloffs in BTC and ETH.

Market reaction typically includes:

• Increased intraday volatility for major crypto pairs.
• Rotation into cash or yield-bearing assets if rate expectations rise.
• Heightened sensitivity to macro data releases and central bank commentary.

COINOTAG analysis: “Investors should watch CPI revisions and Bank of England minutes for directional cues,” says a COINOTAG market strategist.
