Bitcoin dropped below $83,000 on Thursday, a level that FxPro had flagged as a key support point for the cryptocurrency. The firm had warned that a break below the threshold could put BTC on a “quick path to $80,000.”

Bitcoin fell 1.6% to just under $82,800 during Asian morning trading. The decline came as Brent crude moved above $102 a barrel after a report said the White House had asked the Pentagon to develop strike options involving Iran. Treasury yields also climbed toward their highest levels since 2002.

XRP led losses among major cryptocurrencies, falling nearly 4% to around $1.42. DOGE declined 3% to just below 9 cents, while ether dropped 3% to approximately $2,570. HYPE and SOL each fell more than 2%, and ZEC slipped less than 1%. BNB and TRX were the only gainers, rising less than 1% each, according to CoinDesk data.

The move below $83,000 broke bitcoin’s recent low. FxPro said Tuesday that a break of the level would confirm that sellers had gained control. It also warned that such a move could send BTC toward $80,000 “fairly quickly.”

The sell-off followed roughly $550 million in leveraged crypto positions being liquidated a day earlier. Most of the wiped-out positions belonged to traders betting on higher prices, according to CoinGlass data.

Brent crude advanced 2% to above $102 a barrel. The Iran-related report added to other supply concerns, including a storm that disrupted some U.S. oil production. Iran-backed Houthi rebels also attacked two airports in Saudi Arabia, killing three people.

The rise in oil prices pushed the 10-year U.S. Treasury yield 2 basis points higher to 5.31%, bringing it closer to its highest level since 2002.

Global equities also moved lower after recent records. Wall Street benchmarks declined Wednesday after closing at all-time highs the previous day, while Asian shares fell 1%. MSCI’s All Country World Index lost 0.2% and moved farther from the record high it had approached earlier in the week, when it came within 1.5% of the peak.
