Goldman Sachs has revised its USD/JPY forecast sharply higher, projecting the Japanese yen at 162 per dollar in three months, 163 in six months, and 165 within a year — up from a prior 12-month target of 155. The bank declared the yen carry trade structurally durable, describing current conditions as the most favorable for carry trades in over two decades.

This assessment arrives as yen-funded leverage has become a measurable liquidity source for Bitcoin and other risk assets, establishing a direct transmission channel between Japanese monetary policy and crypto market pricing.

The Dual Implication for Bitcoin

Sustained carry trade activity creates a persistent flow of cheap capital seeking yield in higher-returning assets, with a portion flowing into crypto markets. However, the same structural dynamic that provides this tailwind can reverse with extraordinary speed — as demonstrated in August 2024, when an unexpected Bank of Japan (BOJ) move triggered a cross-asset deleveraging event that sent Bitcoin sharply lower within hours.

Goldman Sachs recently reported that carry trades are facing the best conditions in over two decades due to sustained yen weakness, fueling risk asset inflows and benefiting crypto markets. Meanwhile, Bitwise Asset Management named the CLARITY Act as a potential catalyst for…

The central question the market now faces is whether the carry trade's liquidity tailwind can sustain Bitcoin's risk-on bid, or whether the approaching intervention threshold will turn yen weakness into a trigger for the next cross-asset deleveraging event.

The Carry Trade Mechanism Explained

A yen carry trade is mechanically straightforward: a trader borrows in Japanese yen at near-zero interest rates, converts the proceeds into a higher-yielding currency or asset, and captures the spread between the funding cost and the return. The wider the interest rate differential between Japan and the rest of the world, the more attractive the trade becomes. That differential remains stubbornly wide, with the BOJ adjusting its monetary policy at what the primary source describes as a glacial pace — a caution rooted in Japan's decades-long battle with deflation, which has made the central bank historically reluctant to tighten even as peers like the Federal Reserve raised rates aggressively through 2022 and 2023.

The bullish transmission path into Bitcoin operates as follows: cheap yen funding expands the pool of available global leverage, which traders deploy into higher-yielding assets across equities, emerging market debt, credit, and increasingly crypto markets. Elevated risk appetite lifts Bitcoin as institutional positioning grows more aggressive, and sustained USD/JPY weakness extending toward 165 could prolong this dynamic well into 2027 if the rate differential holds.

Goldman's updated forecast implicitly assumes the BOJ continues its unhurried approach to normalization, keeping the funding cost side of the equation anchored near zero.

The Bear Case: Intervention Risk and Forced Unwinds

The bearish transmission path is the mirror image of the bullish one, and it activates fast. Japanese authorities have a documented history of stepping in at psychologically significant USD/JPY levels — spending an estimated $65 billion defending the yen in 2022 when the pair first breached 150, and intervening again in 2024 near 160. Between April and May 2026, authorities intervened to the tune of over 11 trillion yen in an attempt to arrest the yen's slide, with limited lasting effect on the broader depreciation trend. However, the intervention activity signals a clear pain threshold.

As USD/JPY approaches the 163–164 zone and pushes toward Goldman's 165 target, the probability of another intervention event — or more critically, a surprise BOJ rate hike — rises with every yen gained. When the BOJ moved to hike rates in August 2024, Bitcoin and equities sold off sharply in tandem as leveraged positions were rapidly closed, according to supplementary research citing Cointelegraph. Bitcoin fell approximately 18%, Ethereum dropped roughly 26%, and crypto net open interest shed around $13 billion as yen-denominated leverage was rapidly unwound. The episode unfolded over a weekend when crypto markets were the only major venue fully open for continuous trading, concentrating the deleveraging impact before traditional FX and equity markets could absorb and distribute the shock.

JUST IN: Hedge funds are now the most bearish on the Japanese yen since 2007, with nearly 138,000 net short contracts. The yen is trading near its weakest level in decades, and Goldman Sachs now targets 165 per dollar. The trade is becoming extremely crowded. Everyone is… pic.twitter.com/ONwJyqfWjO

Hedge funds currently hold their largest net short yen positions in eight years — near levels last seen in 2007, just before the global financial crisis exposed the fragility of crowded currency bets. An increasing number of market participants now view the short-yen trade as one of the most crowded positions in global currency markets. The more crowded the trade, the more violent any forced unwind becomes — because every participant attempting to exit simultaneously amplifies the yen rally and the margin calls cascading through leveraged books. Bitcoin, trading 24 hours a day with concentrated derivatives exposure, is precisely the asset that absorbs the first wave of that forced selling.
