Bitcoin holds near $66,300 as yen hits 40-year low past 163

Bitcoin rose nearly 1% to $66,300 on Wednesday, consolidating a two-week high, as the yen weakened past 163 per dollar for the first time since 1986.

"The direct trigger of the yen's break below 163 may have been developments in the Middle East. But another big factor was the blueprint, which failed to dispel concern over Japan's fiscal policy," Takahide Kiuchi, executive economist at Nomura Research Institute, said.

The yen touched 163.24 per dollar in New York trade on Tuesday, its weakest since late 1986, before steadying near 163.12 in Asian trading. The slide came as Brent crude futures touched a six-week peak of $91.99 a barrel and US 10-year yields rose to 4.64%, their highest since May. Japan spent 11.73 trillion yen ($92.9 billion) intervening in April and May after the dollar-yen crossed above 160, but the impact has faded.

The yen's persistent weakness reinforces the long-run case for bitcoin as a fixed-supply asset, even if the correlation remains closer to risk assets in the near term. Bitcoin's next test sits at $68,000 resistance, a level analysts say will determine whether the current rally has legs through the summer.

The latest leg higher in bitcoin appeared tied more to a powerful global semiconductor rally than to any crypto-specific catalyst. MSCI's Asia Pacific equities gauge rose 1%, extending Tuesday's biggest one-day gain in a month, with South Korea's Kospi jumping 5% as a leveraged-position unwind that had pulled the benchmark nearly 30% off its peak appeared to be ending. Samsung and SK Hynix led the advance, following a more than 5% jump in a US semiconductor gauge on Tuesday that clawed the index back out of technical bear-market territory.

Ether traded near $1,935, up 3% on the week, while XRP added 2% to $1.14. Hyperliquid's HYPE was the day's laggard, down 4% to $60 and off 10% over seven sessions. Bitcoin's dominance and the muted daily moves across major tokens pointed to a market drifting higher on macro rather than any crypto-native catalyst.

Yen Weakness and the Bitcoin Thesis

A major currency losing a tenth of its value against the dollar, with its central bank unable to stop the slide despite tens of billions spent, is the scenario bitcoin proponents have long argued plays in their favor. The Bank of Japan raised rates to a 31-year high of 1% in June, yet the yen continues to weaken as the Federal Reserve's rate stance and Middle East tensions support the dollar.

Whether that thesis is driving any real flows remains unclear. Bitcoin has tracked chip stocks far more closely than the yen in recent months. But the currency stress is the sort of macro pressure that has historically strengthened the argument for holding a fixed-supply asset, particularly as Japanese authorities' jawboning has done little to reverse the yen's downtrend.
