Bitcoin holds $63,000 as Japan's yen collapse threatens carry trade unwind

Bitcoin traded near $63,000 on Aug. 18 as Japan's yen slid toward 160 per dollar, reviving carry trade unwind fears after an $88 billion intervention faded.

"Japanese economy is generating nominal growth for the first time in decades," David Lebovitz, global strategist at JPMorgan Asset Management, said in a televised interview. "However, growth brought inflation, and inflation crushed the yen."

The yen touched 159.39 per dollar on Aug. 11, approaching the 160 level that previously triggered coordinated intervention. Japan and the US spent $88 billion propping up the currency in late July after it hit a 40-year low near 164. The relief lasted two weeks. Markets now price another BOJ rate hike by October, Japan's third in 12 months, with policy rates at 1 percent versus 3.50-3.75 percent in the US.

The last carry trade unwind in July 2024 sent Bitcoin down about 25 percent in one week to near $49,000 and triggered Japan's worst stock market day since 1987. With the yen back at intervention levels and Japan's biggest insurers nursing $96 billion in bond losses, traders are positioning for a repeat.

Yen's Slide Erases Intervention Gains

The yen's decline has been relentless since the rescue faded. The currency is back near 159.5 per dollar, having given back roughly half of the gains from the late-July intervention. US Treasury Secretary Scott Bessent has said the real fix is higher Japanese rates, and voters are pushing the same way — 71 percent disapprove of Prime Minister Sanae Takaichi's handling of living costs, according to analyst account Bull Theory.

Higher rates already sting at home. Japanese rates sit at their highest since 1995, and the country's biggest insurers are nursing $96 billion in bond losses. Every additional hike makes the cheap yen less cheap, tightening the conditions that have funded risk assets globally for decades.

Bitcoin Stagnates While Gold Rallies

Bitcoin has been notably flat through this period. The asset traded around $63,000-$64,000 through mid-August, essentially unchanged from a week earlier. Meanwhile, gold hit record highs above $4,400 per ounce, suggesting emergency funds are flowing to traditional safe havens rather than crypto assets.

The Bank for International Settlements documented the July 2024 shock in a bulletin, showing how a surprise BOJ hike cascaded through global markets. Bitcoin fell about 25 percent in one week to near $49,000. Japan's Nikkei had its worst day since 1987.

The carry trade survives because the rate gap remains wide. US rates sit at 3.50-3.75 percent while Japan's are at 1 percent. But with the yen back at intervention levels and another BOJ hike priced for October, the conditions for a repeat of the 2024 unwind are building.

For Bitcoin, the risk is asymmetric. A yen shock would likely trigger broad risk-off selling across crypto assets as liquidity tightens. The $60,000 level represents the nearest major support, with $55,000 as the next line if the carry trade unwinds.
