Bitcoin gained on Friday, hovering near the $78,000 mark, helped by risk appetite that also lifted equities. The world’s largest cryptocurrency in the previous session notched its best monthly performance in a year.

Bitcoin was last up 2.2% to $77,949.0 by 17:15 ET (21:15 GMT), rebounding for a second straight day after hitting lows just below $75,000 on Wednesday. For the week, Bitcoin was set for an increase of 0.4%.

The U.S. dollar fell on Thursday, with its weakening against the Japanese yen in particular grabbing the spotlight after a report that the Asian nation had intervened in a bid to prop up its currency.

At 17:33 ET (21:33 GMT), the U.S. dollar index, which tracks the greenback against a basket of six major peers, was down 0.9% to 98.06.

Global oil prices eased after hitting a four-year high of more than $126 a barrel earlier on Thursday on concerns the U.S.-Iran war could lead to a protracted Middle East supply disruption that could inflict deeper damage on the global economy.

Oil prices jumped on Wednesday, after media reports about an extended U.S. naval blockade and a rejection of a peace proposal by Iran kept tensions elevated in the Middle East.

The critical Strait of Hormuz remained shut amid an impasse between the U.S. and Iran, keeping supply disrupted. Traders also digested the United Arab Emirates’ move to leave the OPEC cartel and a widely expected decision by the Federal Reserve to hold interest rates steady.
