Despite muted ETF flows and neutral derivatives sentiment, ETH’s dominance remains unshaken—boasting $64B in TVL, dwarfing Solana, BNB Chain, and Tron combined. With fresh momentum from the recent pectra upgrades and Trump distancing from rival altcoins, all eyes are now on a potential push toward $2,700. 

BTC spot ETFs saw $920.9M in net inflows this week, driven by $1.09B into non-GBTC funds despite $171.5M outflows from GBTC. Since inception, total net inflows stand at $41.1B.

Ethereum outperforms with a 20% rally as fresh capital flows in and undervaluation signals flash

Our monthly report delves into insights from options volatility to inspire your next crypto move.

: April 2025 saw BTC's implied volatility surge above 75% due to tariff chaos, but it collapsed to 35% within a week, indicating a surprising short-term drop in volatility expectations despite ongoing macro uncertainty.

: BTC's return above $100K was met with muted enthusiasm in the derivatives market, suggesting that 

traders no longer view this level as a significant psychological barrier, and the rally isn’t likely to be sustained.

: ETH significantly outperformed BTC with a 23% rally, leading to increased demand for short-dated calls and a positive shift in the options market, highlighting renewed bullish sentiment.

: Historical trends suggest a potential summer lull in volatility in store for BTC, raising questions about whether this pattern will repeat in 2025 amidst ongoing macroeconomic challenges.

Bitcoin’s volatility plunges in late April

April 2025 witnessed significant volatility in the cryptocurrency market, particularly influenced by US trade policies. As President Trump announced steep reciprocal tariffs, the crypto landscape experienced sharp fluctuations. Bitcoin (BTC) initially demonstrated resilience, despite widespread sell-offs in equities and the US dollar, only to succumb to a decline from $88K to $75K by early April. This period was characterized by a dramatic rise in implied volatility that peaked above 75% as traders sought protection through short-dated puts. However, as the tariffs faced moderation, implied volatility plummeted to 35% by mid-April, marking the lowest level since early March.

Interestingly, while short-tenor volatility collapsed, 

the back end of BTC's term structure remained elevated, signaling that market participants expect heightened volatility in the mid-term

. Amidst this backdrop, realized volatility fell below the five-year seasonal average, paralleling similar trends in previous years and suggesting a 

. The historical pattern contrasts that BTC often experiences a rebound in volatility heading into May, raising questions about whether this trend will persist.

Subdued derivative response suggests Bitcoin rally might not endure

The market's reaction to BTC's resurgence above the $100K threshold was notably subdued compared to previous instances. While BTC rallied 20% following the initial tariff sell-off, the derivatives market displayed a muted response. The 25-delta put/call skew, a measure of market sentiment, indicated only a slight bias toward out-of-the-money calls, contrasting sharply with sentiment previously when BTC first breached the $100K mark in December 2024. This lack of exuberance suggests that traders no longer view $100K as a significant inflection point, raising concerns about the sustainability of the rally. 

Meanwhile, funding rates and implied volatility — though still bullish — didn’t reach the extremes observed in earlier months, indicating more cautious market sentiment. The relationship between BTC's spot price and implied volatility suggests that although traders are optimistic, they’re waiting for BTC to approach previous all-time highs before adjusting their volatility expectations.

Ethereum's option data points to further rally

In stark contrast to BTC, Ethereum (ETH) displayed remarkable resilience and outperformed major cryptocurrencies, gaining 23% overnight following favorable trade news. This rally catalyzed a surge in demand for short-dated calls, pushing front-end volatility expectations significantly higher. The response from the derivatives market was robust, inverting the term structure and indicating renewed bullish sentiment toward ETH, even as it’s trading well below its all-time high.

The ETH options market exhibited a shift from neutral to slightly negative skew, to a 10% bias favoring out-of-the-money calls, reflecting the market's confidence in ETH's potential to regain lost ground. Despite overall macroeconomic uncertainty, the demand for ETH options suggests that traders are optimistic about Ether’s future price movements.

In conclusion, April 2025 highlighted the complex interplay between macroeconomic factors and cryptocurrency market dynamics. While BTC faced challenges in eliciting strong responses from derivatives markets upon recrossing the $100K threshold, ETH's performance indicated a divergence in market sentiment. As traders navigate the evolving landscape, the potential for seasonal volatility patterns and the influence of macroeconomic developments will remain critical factors in shaping future market expectations.

Bybit X Block Scholes options volatility report (April 2025): Data suggests Bitcoin rally might not endure, but Ether sees further upside

Our weekly crypto derivatives analytics report delves into macro events; the current state of crypto and trading signals from spot trading volume; and futures, options and perpetual contracts.

After mostly trading sideways at the end of April 2025, a US-UK trade deal sparked a crypto rally. BTC surged past $100K for the first time since February, but it’s ETH's performance that captured the derivatives market's attention. 

A 23% increase in ETH's spot price led to an inverted term structure and a spike in front-end volatility. The put/call skew for ETH shifted from a bearish bias to a nearly 10% skew toward OTM calls. Other sentiment indicators, such as perp funding rates and futures yield, also supported the rally. In contrast, while BTC's funding rates and skew have increased, its implied volatility remains low at 40%, over 30 points below ETH's 7-day implied volatility.

Please check out the report’s highlights.

ETH’s record performance since 2021 was propelled by positive term structure

ETH has significantly outperformed BTC and the top 10 cryptocurrencies, marking its largest single-day gain since May 2021. The options market has reflected this enthusiasm, with implied volatility for short tenors rising sharply and inverting ETH’s term structure, thus contrasting with BTC's muted, positively sloped structure. The 7-day tenor for ETH is now trading at a 33-point premium over that for BTC. 

While puts dominate BTC's open interest, ETH is seeing the opposite trend. On May 8, 2025, options volumes surged over $120M, more than double the typical monthly volume, with $60M more in calls than puts. ETH now boasts a positive futures curve and funding rates, as well as a strong skew toward OTM calls.

ETH sees exceptionally bullish put/call skew

ETH's substantial outperformance in the current crypto rally has led to bullish sentiment in its derivatives markets. Funding rates have surged, futures yields are strongly positive and the put/call skew has shifted significantly toward OTM calls, now close to 10%. This starkly contrasts with early April, when the skew was 20% toward OTM puts. Although ETH has underperformed (relative to BTC and other "ETH killers"), it has rebounded in this rally, with the ETH/BTC ratio rising after spending most of the year declining.

Open interest for Bitcoin options increased, with implied volatility remaining suppressed

The announcement of the new US administration's first trade deal, nearly 30 days into Trump's 90-day tariff pause, jolted crypto markets, pushing BTC back up above $100K. Surprisingly, implied volatility has remained suppressed, failing to invert BTC's term structure, with front-end volatility trading at around an 18-month low of 35-40%. On May 8, 2025, options volumes surged, with call volume reaching $189M, reversing last week's trend of higher put volumes. Meanwhile, open interest rose steadily to exceed $300M, the highest level this month, but remains significantly larger for puts than for calls despite the price increase.

Portfolio margin benefits traders to trade larger positions with less margin required. But is it sustainable and truly beneficial for traders? Learn more. 

Investing in financial markets can be a high-stakes game, with a thin line between success and failure. Traders need to be strategic, agile and smart in managing their positions, especially when trading on margin. That's where Portfolio Margin comes in. 

By taking a holistic approach to margin requirements, traders can potentially reduce their margin requirements, increase their buying power, reduce their costs and add more flexibility to their trading strategies. 

In this article, we'll explore how Portfolio Margin can benefit crypto traders and help them stay ahead.

Sometimes, traders need to borrow funds from their brokers to trade securities or crypto assets, a practice known as trading on margin or 

. “Margin” also refers to the difference between the value of an investment and the amount borrowed. Margin requirements are the minimum amount of funds that traders must deposit with their broker as collateral to open a margin account and trade on margin.

The concept of margin is closely related to 

, which is the use of borrowed capital to magnify your return on investment (ROI). When margin trading, you use funds borrowed from your broker to boost your purchasing power and add leverage.

However, margin trading also comes with additional risks. If the market goes against you, it may trigger a margin call, and you’ll need to deposit additional funds to meet the margin requirements. If you fail to make up the shortfall in margin, the broker can liquidate your position in order to cover the outstanding debt.

Margin requirements can vary depending on the type of asset traded, market conditions and the broker's policies. Understanding margin requirements and the scenarios that may trigger a margin call is essential for successful margin trading.

What Does Portfolio Margin Mean for Traders?

Portfolio margin is a method of calculating margin requirements. It considers the overall risk of a portfolio rather than each position in isolation. By reviewing portfolio-level risk, brokers or exchanges can potentially reduce their margin requirements, which translates into increased buying power and trading flexibility.

Portfolio margin benefits traders by allowing them to trade larger positions with less margin required. This can increase buying power and capital efficiency, potentially opening the door to more trading opportunities.

 margin rules that govern the amount of credit broker-dealers can offer for the purchase of traditional securities. Under Reg T, each position is evaluated separately, with the margin required for each position based on its individual risk. This creates a situation that can lead to higher margin requirements for traders with diversified portfolios, even if their overall portfolio risk is relatively low.

With Portfolio Margin, however, the overall risk of a trader's portfolio is taken into account when calculating margin requirements. The lender nets off the unrealized profits on long and short positions held in different assets against each other. Typically, a diversified portfolio produces lower margin requirements because the net risk of the portfolio is lower than the sum of risk exposures on individual positions.

Portfolio margin is often available to traders who meet specific criteria, such as having a minimum account balance and meeting certain experience requirements. Traders eligible for Portfolio Margin should carefully consider whether it suits their trading style and risk tolerance. One needs to be prepared to manage the potential risks associated with increased leverage.

How Does Bybit UTA Portfolio Margin Mode Help Traders to Maintain a Balanced Portfolio?

 (Unified Trading Account) Portfolio Margin mode is a risk-based margin policy designed to help reduce margin requirements on a balanced portfolio. It offers enhanced capital efficiency and increased leverage. 

When active, Portfolio Margin mode uses financial models to derive the overall risk of your USDC derivatives portfolio by offsetting long and short positions in perpetual and options contracts. It evaluates the range, changes in the mark price, and market volatility of the underlying asset. 

Here’s how Bybit UTA Portfolio Margin mode can help traders maintain a balanced portfolio:

Once the Bybit UTA Portfolio Margin mode is enabled, eligible Bybit users can unlock greater capital efficiency and potentially generate higher returns. 

Portfolio Margin calculates margin requirements based on the overall risk of an investor's entire portfolio, rather than individual positions. This approach offers a few benefits.

For example, suppose a trader has a diversified portfolio of stocks, options and futures contracts. A Portfolio Margin account can allow them to hold their positions with fewer margin requirements than a standard margin account, resulting in lower costs to maintain their positions. In contrast, a standard margin account may require higher margin requirements, making it more expensive to hold the same positions. 

Remember that Portfolio Margining involves unique and significant risks, including increased leverage, which increases the potential loss. There may also be stricter time frames for meeting deficiencies in margin, which raises the risk of involuntary liquidation.

Who Qualifies for Portfolio Margin on Bybit?

Bybit is a leading crypto exchange that offers its Portfolio Margin mode feature to eligible users to help them unlock greater capital efficiency and earn higher returns. Anyone with a Bybit account can qualify for Portfolio Margin. 

To get started with Portfolio Margin mode, users must first meet the following criteria:

Note that Bybit has two margin systems: Isolated margin and cross margin. By default, cross margin is the mode used on Bybit, which uses a trader's available balance to prevent liquidation. However, if the equity of a trading pair is lower than the maintenance margin, the position will be liquidated.

Things to Note When Using Portfolio Margin

Traders using Portfolio Margin should be aware of the risks involved, as well as the potential benefits. They should also monitor their positions carefully, and be prepared to meet margin calls if necessary. 

Overall, Portfolio Margin can be valuable for traders looking to increase their buying power, exercise more flexibility in their trading strategies and potentially save on margin costs. However, traders should also be aware of the risks involved and closely monitor their positions. Be sure to maintain a solid understanding of Portfolio Margin requirements and a clear risk-management plan.

Portfolio Margin may not be suitable for all accounts or trading styles. For example, traders who have a significant amount of unhedged risk, such as a highly concentrated single asset position, may not benefit as much from Portfolio Margin. However, Portfolio Margining offers better flexibility for adding more positions. 

As with any trading strategy, do your own research, seek advice from experienced traders or financial professionals, and carefully consider your risk tolerance and financial goals before using Portfolio Margin.
