Cryptocurrency prices declined during trading on Tuesday, as geopolitical tensions in the Middle East continued, pushing Brent crude prices closer to $100 a barrel and reinforcing fears of renewed inflationary pressures, which could prompt central banks to maintain high interest rates or tighten monetary policy to curb rising prices.

Investors are focused on the US inflation data due on Friday, which could play a pivotal role in determining the Federal Reserve's monetary policy path during September, especially given the markets' sensitivity to any signs of continued inflation.

Meanwhile, markets are heavily pricing in the likelihood of interest rate hikes by the European Central Bank and the Bank of Japan in September, which is putting further pressure on high-risk assets, especially cryptocurrencies.

Cryptocurrencies are typically affected by changes in global interest rate expectations and liquidity, as higher borrowing costs and reduced available liquidity decrease investors' appetite for more volatile assets, while these assets typically benefit from a more accommodative financial environment and lower interest rates.

Despite the decline, Bitcoin is still trading above $78,000, but it has lost more than 10% of its value since the beginning of this year, reflecting continued pressure on the cryptocurrency market despite maintaining relatively high price levels.

In trading, Bitcoin fell by 1.28% to trade at $78,311.25, down by about $1,018.75.

As for the other currencies, Ethereum fell 0.92% to $2,471, a loss of $23.42, while Ripple dropped 0.90% to $1.3858, a decline of about $0.0126.
