Bitcoin falls under the weight of high inflation and interest rate hike expectations

Bitcoin fell sharply overnight following the release of US consumer price index data for September, which came in higher than expected.

The data also revealed a rise in the core inflation index, as the repercussions of higher energy costs spread to the wider economy.

Consumer price index data has fueled concerns that the Federal Reserve will raise interest rates again at least once before the end of the year, which is putting pressure on speculative assets such as cryptocurrencies.

Markets priced in a 70% probability that the Federal Reserve would raise interest rates by an additional 25 basis points in December, following a similar increase in September. CME FedWatch data indicated that expectations of a rate hold in October remained unchanged.

Consumer price index data triggered a sharp sell-off in global technology and artificial intelligence stocks, as investors lowered their estimates for the sector's future earnings amid rising interest rates.

This wave of selling led to a widespread wave of caution in the financial markets, the repercussions of which extended to the cryptocurrency market.
