Bitcoin rose 5% to $80,000 on Sept. 3 as the dollar index fell on suspected Bank of Japan intervention in the yen market.
The yen jumped to a one-month high as traders weighed the possibility of further intervention, though Bank of Japan accounts released Wednesday suggested no major currency action occurred that day, according to Bloomberg calculations. The yen's strength against the greenback pressured the dollar index, which tracks the US currency against six major peers including the yen, euro and pound.
A weaker dollar typically provides tailwinds for risk assets including Bitcoin, as it reduces the effective cost of dollar-denominated holdings for non-US investors and shifts capital toward higher-yielding assets. The move pushed Bitcoin back above the psychologically significant $80,000 threshold, a level that has served as both support and resistance in recent sessions. The rally extended across the broader crypto market as traders interpreted the dollar weakness as a macro tailwind for digital assets.
Traders and analysts remain divided on whether the yen intervention's impact on the dollar will be sustained or fade. If the greenback stabilizes after the initial intervention shock, Bitcoin's rally above $80,000 could face renewed selling pressure. Conversely, continued yen strength that keeps the dollar index under pressure could extend the crypto rally, with traders watching whether $80,000 holds as support in the sessions ahead. The uncertainty around the durability of the intervention's effect introduces volatility risk, and a pullback remains possible if the dollar regains its footing.
