Bitcoin (CRYPTO: $BTC ) is struggling to remain above $75,000 U.S. as Treasury yields continue to rise, pressuring risk assets such as cryptocurrencies and stocks.

Both 10-year and 30-year U.S. Treasurys have been steadily rising over the past week, with the 30-year government bond reaching 5.13%, its highest level since 2007.

Government bonds are climbing higher after the U.S. inflation rate reached an annualized 3.8% in April, raising the prospect of higher interest rates later this year.

The upswing in U.S. Treasury yields is putting downward pressure on stocks and cryptocurrencies such as Bitcoin.

As a result, the price of BTC has fallen from a peak of $82,000 U.S. to as low as $76,000 U.S. over the past week.

Bitcoin is currently treading water at just over $77,000 U.S. Other leading cryptocurrencies have also been sinking in recent trading sessions.

Ethereum (CRYPTO: $ETH ) has dropped from near $2,500 U.S. to $2,100 U.S. as investors move away from risk assets.

Despite the price slump, Bitcoin's implied volatility remains low.

Bitcoin's 30-day implied volatility index, BVIV, has held steady at around 42% in recent days, just above its year-to-date low of 40%, according to data from TradingView.

Crypto analysts say the low volatility is a positive sign that could imply a quick rebound in prices for digital assets should Treasury yields peak and then move lower.

Some analysts are warning that "volatility bulls" could step in and bet on wild swings in the price of Bitcoin via the options market.

BTC hit an all-time high of just over $126,000 U.S. last October.
