Japan yields rise, USDe drops

Today, we break down the BTC move during Asia hours and the renewed pressure from Japan’s carry unwind. We then look at China’s latest crypto FUD and track the continued USDe deleveraging cycle ahead of Pendle expiries, mapping what needs to shift for Ethena yields to recover.

BTC dropped about 5% in early Asia hours, trading near $86K. The move hit thin late-weekend liquidity and flushed several hundred million of long leverage.
On the rates side, Japan is again reactivating the yen-carry unwind. Two-year Japanese Government Bonds (JGBs) trade near 1%, 10-year yields are around 1.9%, both the highest since 2008. Overnight Interest Swaps now price about 80% odds of a December hike from the BOJ.

The last surprise move in mid-2024, when the BOJ lifted rates to 0.25%, drove a sharp USDJPY reversal and contributed to a near 30% BTC drawdown to roughly 49K as macro books de-grossed risk. A similar pattern appeared today, with BTC tracking the Nikkei lower during Asia hours.

The underlying mechanism is unchanged. Global macro funds and institutions borrow yen or short JGBs to fund higher yielding USD and EUR assets. As JGB yields rise, the yen funding leg becomes more volatile and more expensive. Investors reduce carry books and cut the highest beta exposures first, so BTC sits at the front of the liquidation stack.
The September 2024 BIS Quarterly Review quantified the size and opacity of this ecosystem:
Notional FX swaps and forwards with JPY on one side reached $14.2 trillion dollars (about 1,994 trillion yen). These positions sit off balance sheet and do not appear in conventional debt metrics.
Visible on balance sheet yen loans to foreign non-banks totaled only $271 billion dollars, confirming that most yen borrowing happens through derivatives rather than loans.
About $1.7 trillion dollars of yen liquidity is provided by non-bank financial institutions like trustee accounts. These allocators are volatility sensitive and are prone to withdraw liquidity quickly under stress.
As yen becomes more expensive, positions need to be unwound. This forces both de-risking in high beta assets and mechanical JPY buying, which can feed a reinforcing loop as yen strengthens.
Adding fuel to the fire, China added another catalyst. The PBoC reiterated that all virtual currency trading remains illegal and explicitly categorized stablecoins under AML and capital flight restrictions. Hong Kong crypto-linked equities reacted immediately: Yunfeng Financial fell more than 10%, Bright Smart dropped about 7%, and OSL Group declined over 5%.
The substance of the policy is not new, and it seems this is the hundredth time China is banning crypto. However, the price reaction is significant, and shows we are still in a highly skittish regime.

On last week's podcast, we went live with Figment Capital’s Jim Parillo to discuss DeFi infrastructure, Hyperliquid’s ecosystem and the movement of intellectual capital toward perpetual markets. We:
analyzed the architectural distinction of Hyperliquid’s ecosystem, noting that unlike general-purpose EVM chains, Hyperliquid features a central flagship application (HyperCore) which necessitates a "pyramid" builder strategy focused on complementary infrastructure like prime brokerages rather than generic forks of lending protocols or NFT marketplaces.
detailed the significant friction currently involved in bridging assets between HyperEVM and HyperCore, outlining a complex multi-step process involving depositing LSTs to borrow HYPE, utilizing platforms like Felix to borrow USDT, and executing swaps to finally acquire usable USDC for trading.
discussed the value proposition of rebalancing leveraged tokens through the lens of Figment Capital's investment in Bounce, highlighting how these products mitigate liquidation risk during volatility wicks — a persistent issue for retail traders managing high-leverage perpetual positions.
explored the retail psychology regarding onchain derivatives, contrasting the dominance of perpetuals against the lack of adoption for options, and examined how Euphoria is attempting to capture retail flow by simplifying short-duration options into a gamified "squares" interface.
evaluated the structural challenges of pre-IPO and pre-market assets, observing that market makers cannot effectively maintain delta-neutral positions for isolated assets lacking deep spot markets, which results in prohibitively high premiums compared to liquid traditional finance markets.
noted the potential impact of listed options on spot crypto ETFs (such as IBIT), suggesting that the arrival of deep institutional liquidity in these venues could eventually help normalize pricing models for onchain derivatives that currently suffer from fragmentation.

Charts of the week
The Oct. 11, 2025, liquidation episode was the largest in crypto’s history. A Trump tariff tweet sent BTC from about $120K to roughly $102K and wiped out about $19 billion dollars of open positions in 24 hours. USDe traded as low as $0.65 on Binance and about $0.92 on Bybit. Despite this, Ethena processed $1.9 billion of redemptions, maintained full backing and contained systemic contagion. Combined with Bybit’s February $1.5 billion exploit, this was a second major stress event that USDe passed with flying colors. However, despite that resilience, USDe supply has fallen almost 50% from the $14 billion dollar peak to about $7 billion.
The driver behind this is unattractive carry. Following October's OI wipeout, funding rates for BTC and ETH are muted to negative, with Ethena’s dashboard showing negative funding across majors. Since November, the sUSDe spread has been below three-month Treasury yields.

With core delta-neutral strategy being unprofitable or returning low yields, 63.3% of the system is now held in liquid stables rather than deployed in delta neutral carry.

The unwind also shows up in Aave and Pendle TVL.
sUSDe looping became unattractive as sUSDe yields fell below USDC borrow rates (4.87% USDC borrow vs 4.77% sUSDe APY).
The November Pendle sUSDe PT expiry removed most of the size from Aave, and exposure fell from more than $5.4 billion to about $340 million.
Going forward, the market needs to assess whether new expiries will attract significant utilization. The February 2026 PT implies a yield of only 5.8%, the lowest of any previous expiry, and at current levels, looping against Aave borrow rates is not profitable, so Aave PT utilization should remain low. Secondly, sUSDe rates must climb back above USDC borrow rates to continue to see demand on Aave.

Therefore, until funding turns frothy, Ethena’s core engine remains impaired. And as crypto becomes more institutionalized, with larger market makers and deeper derivatives liquidity, our base case is that funding rates trend structurally lower. For yields to recover, directional appetite must return so perp basis widens, and ETH vol needs to rise so positive funding can re-establish itself.
