Why Bitcoin consistently rebounds to $70k — and the $13B options influence driving it

Bitcoin’s recovery on March 4 appeared unusual when viewed solely through the typical lens of “risk assets are faltering.” Oil prices were surging, shipping insurers were adjusting war risk assessments, and traders were treating the Strait of Hormuz as a volatile zone. The headlines suggested a significant crisis was unfolding.

Nevertheless, Bitcoin managed to return to the $70,000 range it has been hovering around for several weeks, despite experiencing a significant decline the previous weekend.

Two key factors account for this movement.

The first is a rather clear macroeconomic influence. When the Middle East experiences oil shocks, markets swiftly adjust to account for increased energy costs, disrupted supply chains, and a variety of other adverse outcomes. Joint military actions by the US and Israel against Iran, along with retaliatory strikes throughout the Gulf, caused disturbances in the Strait of Hormuz, resulting in a substantial energy shock.

As tensions in the Strait escalated, war risk insurance and freight rates surged, leading to a rapid increase in oil and gas prices.

The second factor involves derivatives. While it is not the sole reason for the recovery, it clarifies why Bitcoin can decline sharply and then rebound into a familiar price range, even as market anxiety persists. The most significant impact arises from options, where hedging flows can draw the price toward crowded strike zones.

The macroeconomic shock ignited the initial movement, but the options market provided the necessary conditions already established around $70,000.

The initial shock affecting everything: oil, Hormuz, and fuel transportation costs

The Strait of Hormuz serves as a vital transit chokepoint in the global oil and gas market. Data from 2024 indicated that approximately 20 million barrels traversed the Strait daily, accounting for about 20% of total global petroleum liquid consumption. (eia.gov)

When circumstances in this narrow passage deteriorate, the market rapidly adjusts logistics, insurance, and the practical capacity to export.

From February 28 to March 4, the conflict in Iran sent the oil market into one of its most significant shocks in decades. The subsequent strikes and retaliations jeopardized exports from the world’s most crucial oil-producing region.

As traffic through the strait diminished, shipping expenses soared, and insurers began withdrawing coverage and expanding risk zones, with some shipping companies even rerouting around the Cape of Good Hope.

Oil is essential to the global economy, and fluctuations in oil prices impact a wide range of sectors. It influences everything from transportation costs and airline operations to heating expenses, food logistics, and inflation expectations.

Thus, when oil prices rise due to threats to the world’s most critical transit route, investors across markets pose similar questions: where does the risk shift now?

Why Bitcoin initially declined, then recovered while anxiety remained high

Bitcoin’s initial reaction to a macroeconomic shock often resembles a straightforward series of liquidations. Attributing it to liquidations is not unexpected, considering that Bitcoin trades continuously, in substantial volumes, and with fewer friction points than many other assets. Consequently, when traders seek to reduce exposure quickly, they sell what they can liquidate promptly.

Indeed, part of this is accurate. Bitcoin fell following the weekend strikes, with nearly $1 billion liquidated between February 28 and March 1.

This forms the macro narrative: when a shock occurs, BTC sells off rapidly and in large quantities.

However, the missing element is why it rebounded more swiftly than other assets and continued gravitating toward the same price range that has been significant for weeks. This is where the options market becomes relevant.

The $70,000 range is a busy intersection in options

Options come with complex terminology and various Greek letters, often causing them to be overlooked during macroeconomic shocks. However, crypto options, particularly Bitcoin options, have grown so substantial that they exert their own gravitational influence.

Large institutions now hold options positions so significant that even minor daily price fluctuations compel them to hedge.

Gamma indicates how quickly an option’s sensitivity changes as the price fluctuates. When gamma is elevated, small movements in Bitcoin can necessitate larger hedge adjustments. This type of trading can accelerate and amplify short-term price swings.

The peak gamma area for options expiring on March 5 and March 6 was approximately $71,000, with a heightened range from about $70,500 to $73,000. This is the zone where hedging sensitivity reaches its peak.

Within this area, the market can feel primed for movement, and both dips and rallies tend to occur more rapidly due to the scaling up of the hedging response.

The strike data supports this observation. CoinGlass data reveals significant exposure between $70,000 and $75,000, indicating that these two strikes are primarily responsible for the activity.

At $70,000, open interest stands at approximately 9.3k puts and 9.25k calls, equating to around $1.32 billion in notional exposure. At $75,000, open interest comprises about 17.36k calls and 9.41k puts, roughly $1.9 billion in notional. These figures create a corridor where a significant amount of risk is tied to a narrow range of prices.

This can be likened to traffic patterns. A city has numerous roads, but congestion occurs at chokepoints where many routes converge. The chokepoint exists because the layout directs activity through it, and strike clusters function similarly: they channel hedging flows through a limited price range.

March 27 is significant due to concentrated behavior around deadlines

Examining expirations reveals one date that stands out: March 27.

This expiration encompasses approximately 111.7k calls and 74.97k puts, totaling around $13.27 billion in notional exposure.

The total BTC options open interest also increased from about $32 billion in late February to approximately $36 to $37 billion in early March, enhancing the impact of options-related flows during a volatile period.

Large expirations concentrate trading behavior as time compresses, prompting traders to roll positions forward and compelling dealers to manage risk more closely. Hedging can become more intense as the calendar approaches a significant expiration.

This is why the magnetic influence of specific price points often intensifies as expiration windows approach.

As the calendar inches closer to March 27, the strike corridor around $70,000 and $75,000 can function like a rail. Prices continue to fluctuate, and headlines remain relevant, while the market consistently encounters the same concentrations of risk.

The connection between oil and options

The oil shock generated the volatility, and the options market determined the trajectory of the price as the recovery took shape.

A clear sequence aligns with the timeline from February 28 to March 4.

Initially, oil and shipping markets rapidly adjusted risk as conditions in Hormuz worsened and export logistics tightened.

Next, Bitcoin experienced a sell-off in the initial wave due to its liquidity and continuous trading, as investors broadly reduce exposure during periods of heightened volatility. (fortune.com)

Subsequently, as the selling subsided and prices began to recover, Bitcoin encountered a corridor where options exposure is dense between $70,000 and $75,000, with peak gamma around $71,000, where hedging sensitivity is at its highest. A rebound that enters this band can become more responsive because hedgers must adjust more frequently.

Lastly, funding dynamics contribute additional momentum. CoinGlass data indicated repeated negative funding spikes from late February into early March, each followed by price rallies. This aligns with a market that is leaning short, as rising prices prompt short covering, adding buying pressure. Such buying can propel prices into the strike corridor more rapidly, and the high gamma band can amplify the movement once prices reach that level.

Why the $70,000 corridor may continue to emerge into late March

A $13.27 billion expiration acts as an anchor. Significant expirations draw trading activity toward strikes with substantial open interest, as that is where rolling and hedging are most concentrated. Strike data indicates $70,000 and $75,000 as key nodes within that corridor.

Simultaneously, the macroeconomic environment remains tense. Ongoing volatility keeps Bitcoin functioning as a liquid release valve. It tends to sell off early during shocks and then rebounds into the areas where derivatives positioning concentrates flows.

This is why the $70,000 level may persist as a target, even when news headlines are unrelated to crypto. The market consistently returns to this area because that is where the current risk resides.

Three factors to monitor moving forward

There is no need to analyze an options chain to determine if the $70,000 corridor narrative remains valid.

Observe where the largest strike concentrations are located. If open interest increases, the corridor will shift accordingly, and if it decreases, the corridor will adjust downward.

Keep an eye on the calendar. March 27 represents the largest expiration we have seen in some time, and significant expirations often reshape positioning as traders roll or close their risk.

Monitor the macro volatility linked to oil and shipping. The situation in Hormuz has driven up crude and shipping costs. (reuters.com) If this trend continues, Bitcoin is likely to maintain its status as a fast, liquid asset that sells off quickly and then rebounds into the derivatives zones that concentrate hedging.

An oil shock unsettled markets, causing Bitcoin to initially drop sharply due to its liquidity. The subsequent rebound then flowed into a corridor between $70,000 and $75,000, where options positioning, hedging sensitivity, and a significant late-March expiration make price movements more reactive around the same set of levels.
