Yesterday, $4.7 trillion in derivatives expired during the March 2026 quadruple witching. Stock index futures, stock index options, stock options, and single stock futures — all settling simultaneously on the third Friday of the quarter. Bitcoin held ~$69,800 through the event itself, barely flinching while equity desks scrambled to manage the largest notional expiration of the year.
But here is what most families watching Bitcoin miss: the witching day isn't the event. The 1–3 weeks after witching are the event.
In September 2025, Bitcoin was near $177,000 on quadruple witching day. Over the following three weeks, it dropped to $108,000 — a 39% drawdown that coincided with dealers unwinding gamma exposure and institutional portfolios rebalancing without hedging cover. In June 2025, Bitcoin drifted to its local cycle bottom just two days after witching. The pattern is consistent: witching day holds, post-witching drifts.
Now add the second shoe: on March 27 — next Thursday — approximately $13.5 billion in crypto-specific derivatives expire on Deribit, the dominant crypto options exchange. This is not a generic equity event. This is direct crypto exposure unwinding one week after the equity witching. Two sequential expiration waves in eight days.
Bitcoin currently sits around $70,000. The Fear & Greed Index reads 25. And for families with significant Bitcoin positions, the next two weeks represent what may be the best estate planning transfer window of 2026.
This article lays out the mechanics — why post-witching weakness happens, how the March 27 Deribit expiry extends the window, and exactly what estate planning moves the math supports over the next 14 days.
What Quadruple Witching Is and Why It Creates a Post-Event Drift
Quadruple witching occurs four times a year — the third Friday of March, June, September, and December — when four classes of derivatives expire simultaneously: stock index futures, stock index options, individual stock options, and single stock futures. The March 20, 2026 event saw approximately $4.7 trillion in notional value expire, making it one of the largest single-day derivative settlements in market history.
The mechanics of witching day itself are actually stabilizing. Market makers who sold options must maintain delta-neutral positions as contracts approach expiration. They buy when prices fall and sell when prices rise — providing a dampening effect that keeps volatility compressed on the actual day. This is why Bitcoin held $69,800 relatively calmly through Friday's session.
Why the Real Move Comes After
The post-witching drift happens because of what disappears after expiration, not what happens during it:
- Gamma exposure evaporates. On witching day, billions of dollars in options gamma force market makers to hedge actively — buying dips, selling rips. The moment those contracts expire, that mechanical buying support vanishes. Price can move more freely, and typically does.
- Portfolio rebalancing creates directional flow. Institutional portfolios that were hedged through witching suddenly need to rebalance without the options overlay. This creates sustained directional selling (or buying) over the 1–3 weeks following expiration as managers adjust positions to their target allocations.
- New options cycle takes time to establish. The fresh quarterly options that begin trading after witching need 1–2 weeks to build meaningful open interest. During this transition, the stabilizing effect of deep options markets is diminished.
- Dealer hedging flows reverse. Market makers who accumulated positions to hedge the expiring contracts unwind those hedges over the following days. For assets correlated with equity volatility — including Bitcoin — this unwind can create selling pressure that has nothing to do with fundamentals.
The result: a predictable window of elevated volatility and downward price drift that typically peaks 1–2 weeks after witching day and resolves as the new options cycle matures.
Bitcoin is not part of the equity derivatives complex. But since 2024, the correlation between Bitcoin and equity market structure events has strengthened as institutional capital — pension funds, family offices, RIAs — holds Bitcoin alongside equities in multi-asset portfolios. When these portfolios rebalance after witching, the Bitcoin allocation rebalances too. Additionally, macro-sensitive hedge funds that trade Bitcoin alongside equity index futures adjust both positions simultaneously. The result: Bitcoin experiences post-witching drift even though no Bitcoin-specific derivatives expired on March 20.
The Historical Post-Witching Bitcoin Pattern
Theory is useful. Data is better. Here is what actually happened to Bitcoin after the last several quadruple witching events:
September 2025: The Sharpest Post-Witching Drawdown
On September 19, 2025 — quadruple witching day — Bitcoin was trading near $177,000. The day itself was unremarkable: price held within a 3% range as gamma hedging compressed volatility. Then the unwind began.
Over the following three weeks, Bitcoin dropped to approximately $108,000. That's a 39% decline — $69,000 per coin of drawdown that occurred entirely in the post-witching window. The drivers were a combination of equity portfolio rebalancing (the S&P 500 also dropped 8% in the same window), dealer gamma unwind, and a cascading liquidation of leveraged long positions in the crypto futures market that amplified the move.
For a family that held 100 BTC and was considering an irrevocable trust transfer, the difference between acting on September 19 at $177,000 and acting on October 8 at $108,000 was enormous: at $108,000, the same $15 million lifetime exemption bought 138.9 BTC instead of 84.7 BTC — 54 additional Bitcoin transferred outside the estate using identical exemption dollars.
June 2025: The Quick Drift
The June 20, 2025 quadruple witching was more contained. Bitcoin held roughly flat on the day, then drifted to its local cycle bottom just two days later on June 22. The total decline was approximately 7% — less dramatic than September, but still a meaningful window for families executing annual exclusion gifts or Crummey trust contributions.
March 2025 and December 2024: Consistent Pattern
Both the March 2025 and December 2024 witching events showed variations of the same pattern: relative stability on witching day followed by 1–3 weeks of post-event drift. The magnitude varied (5–15% declines), but the directionality was consistent — Bitcoin weakened in the weeks following every quadruple witching over the past 18 months.
| Witching Date | BTC on Day | BTC Low (1-3 Weeks After) | Post-Witching Decline |
|---|---|---|---|
| Dec 20, 2024 | ~$97,000 | ~$89,000 | -8.2% |
| Mar 21, 2025 | ~$84,000 | ~$76,000 | -9.5% |
| Jun 20, 2025 | ~$142,000 | ~$132,000 | -7.0% |
| Sep 19, 2025 | ~$177,000 | ~$108,000 | -39.0% |
| Mar 20, 2026 | ~$69,800 | In progress | Window open now |
The March 27 Deribit $13.5B Second Wave: Why the Setup Runs Through End of Month
The March 20 equity witching would be significant on its own. But this cycle has an amplifier: on March 27, approximately $13.5 billion in crypto-specific derivatives expire on Deribit.
Deribit is the dominant crypto options exchange, handling over 85% of all Bitcoin and Ethereum options volume globally. Unlike equity witching — which affects Bitcoin only through correlation and portfolio rebalancing — the Deribit expiry directly involves Bitcoin options contracts. When these expire, the delta hedges that Deribit market makers hold in spot Bitcoin unwind. That unwinding creates real selling pressure on actual Bitcoin, not just correlated flow.
The Two-Wave Setup
Here is why the combination matters for estate planning timing:
- Wave 1 (March 20–26): Post-equity-witching drift. Dealers unwind gamma, institutional portfolios rebalance, Bitcoin experiences correlated selling. This is happening now.
- Wave 2 (March 27 – April 3): Deribit crypto derivatives expire. Market makers unwind delta hedges in spot Bitcoin. Open interest resets. A second period of elevated volatility and potential weakness begins before the new monthly cycle establishes.
The practical implication: the post-witching estate planning window doesn't close on March 27 — it potentially extends through end of month or early April as the Deribit expiry creates a second wave of the same structural dynamics.
For families considering GRAT resets, irrevocable trust transfers, or accelerated annual exclusion gifting, this two-wave structure provides a 14-day window — March 21 through approximately April 3 — during which the math may be at its most favorable.
March 2026 Derivatives Expiry Calendar
- March 20: Quadruple witching — $4.7T equity derivatives expire. Bitcoin holds ~$69,800.
- March 21–26: Post-equity-witching drift window. Gamma unwind, portfolio rebalancing.
- March 27: $13.5B Deribit crypto derivatives expire. Direct Bitcoin options settlement.
- March 28 – April 3: Post-Deribit unwind. Delta hedge reversal in spot BTC.
- Key insight: Two sequential expiry events create an extended weakness window vs. typical single-witching quarters.
GRAT Reset: The Math for Resetting at $70K vs. $80K vs. $90K
A Grantor Retained Annuity Trust is the premier vehicle for transferring Bitcoin appreciation to the next generation at zero gift tax cost. The mechanics are explained in detail in our comprehensive Bitcoin GRAT guide — here, we focus specifically on why the post-witching window makes a GRAT reset unusually attractive.
The Reset Mechanics
A GRAT reset involves unwinding an existing GRAT (returning the annuity stream to the grantor) and funding a new GRAT at the current, lower Bitcoin price. The new trust starts the wealth-transfer clock from a lower baseline. Any appreciation above the new funding price plus the §7520 hurdle rate passes to beneficiaries gift-tax-free.
With the March 2026 §7520 rate at approximately 5.0%, here's how the math differs depending on when you reset:
| Metric | Reset at $90K | Reset at $80K | Reset at $70K |
|---|---|---|---|
| Funding price per BTC | $90,000 | $80,000 | $70,000 |
| 2-year hurdle (~5.0% §7520) | ~$99,225 | ~$88,200 | ~$77,175 |
| Surplus if BTC hits $120K | $20,775/coin | $31,800/coin | $42,825/coin |
| Surplus on 50 BTC GRAT at $120K | $1.04M | $1.59M | $2.14M |
| Surplus if BTC hits $150K | $50,775/coin | $61,800/coin | $72,825/coin |
| Surplus on 50 BTC GRAT at $150K | $2.54M | $3.09M | $3.64M |
| Gift tax cost (zeroed-out GRAT) | $0 | $0 | $0 |
The difference between resetting at $90K and $70K on a 50-BTC GRAT with Bitcoin recovering to $150K is $1.1 million in additional tax-free wealth transfer. Scale to a 200-BTC position and the difference is $4.4 million. These are not marginal improvements — they are the kind of numbers that compound across generations.
When NOT to Reset
A GRAT reset isn't universally optimal. It creates legal and administrative costs. The new GRAT restarts the term clock, meaning you need a full new term for Bitcoin to clear the hurdle. If you're near the end of an existing GRAT term and Bitcoin is above the original hurdle, unwinding sacrifices the surplus you've already earned. The reset is most attractive when:
- The original GRAT was funded at a price 20%+ above current price
- Substantial term remains on the existing GRAT
- You have conviction Bitcoin will recover above the new hurdle within the new term
- The administrative cost of reset is small relative to the surplus improvement
The post-witching period is particularly attractive for GRAT resets because the weakness is structurally driven — not fundamentally driven. Bitcoin isn't declining because of protocol failure or regulatory action. It's declining because of derivatives mechanics and portfolio rebalancing flows that are, by definition, temporary. This means the probability of recovery above the new hurdle is supported by the structural nature of the drawdown. Consult your estate planning attorney to model the specific reset math for your GRAT — the §7520 rate applicable at funding locks in for the entire term.
Irrevocable Trust Transfers: Why the Next 14 Days Are the Window
Beyond GRATs, the post-witching window applies to all irrevocable trust transfers — dynasty trusts, spousal lifetime access trusts (SLATs), intentionally defective grantor trusts (IDGTs), and any completed gift to an irrevocable vehicle. The principle is identical: lower price means more Bitcoin per dollar of exemption consumed.
For comprehensive guidance on irrevocable trust structures, see our Bitcoin irrevocable trust guide.
Why 14 Days, Specifically
The two-week framing isn't arbitrary. It's driven by the structural calendar:
- Week 1 (March 21–27): Post-equity-witching drift is at its most intense during the first week. Dealer gamma unwind, forced rebalancing, and the approach of the March 27 Deribit expiry keep selling pressure elevated.
- Week 2 (March 28 – April 3): Post-Deribit unwind creates a second pressure wave. But by mid-week 2, the new options cycles begin establishing meaningful open interest, gamma stabilization returns, and the structural drivers of weakness begin to fade.
- After April 3: The window likely closes. New quarterly options build depth, hedging flows normalize, and the market settles into its new post-expiry regime. Historically, the post-witching drift resolves within 2–3 weeks of the witching date.
This means the optimal transfer window is right now through approximately April 3. Families that wait until "things settle down" will likely be making transfers at prices 10–30% higher, based on the historical pattern of post-witching recovery.
The Exemption Math at Current Prices
Under the One Big Beautiful Budget Act (OBBBA), the current lifetime gift and estate tax exemption is approximately $15 million per individual ($30 million per married couple). Here is how the current post-witching price compares to likely recovery levels:
| Metric | BTC at $70K (Now) | BTC at $85K (Recovery) | BTC at $100K |
|---|---|---|---|
| BTC per $1M exemption | 14.29 BTC | 11.76 BTC | 10.00 BTC |
| BTC per $15M (individual) | 214.3 BTC | 176.5 BTC | 150.0 BTC |
| BTC per $30M (couple) | 428.6 BTC | 352.9 BTC | 300.0 BTC |
| Advantage vs. $100K | +128.6 BTC (couple) | +52.9 BTC (couple) | — |
| Value of advantage at $250K/BTC | +$32.1M | +$13.2M | — |
A married couple that transfers Bitcoin into an irrevocable trust during the post-witching window at $70,000 instead of waiting for $100,000 moves an additional 128.6 BTC outside the taxable estate. At a future Bitcoin price of $250,000, that's $32.1 million in additional generational wealth — using the same exemption dollars.
The irrevocable nature of the transfer is the point, not the risk. Once Bitcoin is in the irrevocable trust, all future appreciation occurs outside your taxable estate. You want to make the transfer when the starting value is lowest — because that maximizes the appreciation that escapes estate tax. The post-witching window, by suppressing price through structural mechanics, creates exactly that opportunity.
Annual Exclusion Gifting: $19K Individual / $38K Married — How Lower Price Amplifies This
Annual exclusion gifts are the most accessible estate planning tool, and they become significantly more powerful during post-witching weakness. In 2026, each individual can gift up to $19,000 per recipient without consuming any lifetime exemption. Married couples using gift splitting double this to $38,000 per recipient.
The Post-Witching Annual Exclusion Advantage
| Metric | BTC at $100K | BTC at $70K (Now) | Advantage |
|---|---|---|---|
| BTC per $19K gift (individual) | 0.190 BTC | 0.271 BTC | +42.6% |
| BTC per $38K gift (couple) | 0.380 BTC | 0.543 BTC | +42.6% |
| 10 recipients (couple), annual | 3.80 BTC | 5.43 BTC | +1.63 BTC |
| Value at $250K/BTC | $950K | $1.36M | +$407K |
A married couple with 10 beneficiaries (children, grandchildren, their spouses) who makes annual exclusion gifts during the post-witching window at $70K instead of during a normal market at $100K transfers 1.63 additional BTC per year. Over five years of disciplined witching-window gifting, that's 8.15 additional BTC — worth over $2 million at $250K/BTC. All without touching a single dollar of lifetime exemption.
Timing the Contribution Within the Window
Annual exclusion gifts don't have to happen in December. They can happen any time during the calendar year. The most tax-efficient approach is to make contributions during periods of maximum price weakness — which is exactly what the post-witching window provides. If you have Crummey trusts for your children or grandchildren, fund them now. Send the Crummey notices immediately after contribution. The $19,000 buys 42.6% more Bitcoin today than it will when the window closes.
The convention of making annual exclusion gifts at year-end is a habit, not a strategy. There is zero tax advantage to waiting until December. The advantage goes to the family that contributes during the post-witching weakness window in March — buying more satoshis per exclusion dollar — rather than in December when prices have likely recovered. If your Crummey trust is already established, the contribution can happen this week. If it isn't, start the drafting process now — attorney drafting plus Crummey notice cycle takes 3–6 weeks.
What NOT to Do: Panic-Selling Inside a Trust, Breaking Multi-Sig Under Duress
Post-witching weakness creates planning opportunities. It also creates emotional pressure that leads to the most destructive mistakes in Bitcoin estate planning. Here is what to avoid — emphatically.
1. Do Not Panic-Sell Bitcoin Inside an Irrevocable Trust
If you already hold Bitcoin inside an irrevocable trust, the estate planning benefit is locked. The Bitcoin was transferred at a specific gift tax valuation. Selling inside the trust crystallizes a loss but does not improve the estate planning math — the exemption was already consumed at the transfer date valuation. Worse, selling eliminates the trust's exposure to the recovery that follows post-witching weakness, which defeats the entire purpose of holding Bitcoin in a generational vehicle.
A trustee's job during post-witching weakness is to hold, not to trade. The Investment Policy Statement should govern trustee action — not the Fear & Greed Index.
2. Do Not Break Multi-Signature Custody Under Emotional Duress
Multi-signature custody structures (2-of-3, 3-of-5) exist precisely for periods like this. They introduce friction between the impulse to act and the execution of that action. During post-witching weakness, the temptation to "consolidate keys" or "simplify custody" in order to sell faster is a red flag. If you're feeling urgency to reduce your custody security, that urgency is almost certainly emotional, not rational.
The multi-sig stays intact. The custody architecture was designed for this moment.
3. Do Not Make Irrevocable Decisions Without Running the Numbers
Post-witching weakness is a transfer opportunity — not an emergency. The math should drive the decision, not the sentiment. Before making any irrevocable trust transfer, GRAT reset, or significant gift, calculate the specific exemption efficiency gain at current prices versus your expected recovery price. If the gain is material (20%+ more BTC per exemption dollar), act. If the gain is marginal, the administrative costs of restructuring may outweigh the benefit.
4. Do Not Assume the Window Is Permanent
Equally dangerous: assuming that because post-witching weakness has occurred before, it will continue indefinitely. The structural window is approximately two weeks — through the Deribit expiry unwind — not two months. Families who decide to "wait for an even lower price" may find the window has closed and prices have recovered before they act. The goal is not to time the exact bottom. The goal is to act when the math is favorable, which it is right now.
The test for every action during post-witching weakness: Would I be comfortable explaining this decision to my heirs in 20 years? Panic-selling fails that test. Breaking multi-sig fails that test. Making a disciplined irrevocable transfer at depressed prices passes it every time.
IPS Discipline: The 4 Triggers That Should Govern Trustee Action During Post-Witching Periods
Every Bitcoin trust should have an Investment Policy Statement (IPS) that governs trustee behavior during volatility events. Post-witching weakness is exactly the scenario the IPS exists for. Here are the four triggers that should — and should not — prompt trustee action:
Trigger 1: Price-Based Transfer Thresholds
The IPS should define specific price levels at which additional Bitcoin transfers into the trust become optimal. Example: "When BTC drops 15%+ below the 90-day moving average, evaluate irrevocable trust contribution at current price. If exemption efficiency gain exceeds 20% versus recent high, execute." This converts the emotional question ("Should we do something?") into a mechanical one ("Did the threshold trigger? Yes/no.").
Trigger 2: Structural Event Calendar
The IPS should include known structural volatility events — including quadruple witching dates — as pre-scheduled evaluation triggers. Not action triggers. Evaluation triggers. When witching occurs, the trustee reviews the post-witching pattern, checks current price against transfer thresholds, and either executes or documents why no action was taken. The March 20 equity witching and March 27 Deribit expiry are both structural events that warrant IPS evaluation.
Trigger 3: Fear & Greed Threshold
A Fear & Greed reading below 25 should trigger an IPS review of all pending estate planning actions — annual exclusion contributions, GRAT resets, trust funding. The current reading of 25 is at the threshold. The IPS should specify: "When Fear & Greed drops below 25, trustee and grantor will confer within 48 hours to evaluate accelerated transfer actions."
Trigger 4: Time-Based Rebalancing
The IPS should include quarterly reviews timed to coincide with post-witching windows — because these are the quarters when transfer math is most likely to be favorable. The March quarterly review should be happening this week, not in April when prices may have recovered.
The IPS prevents both bad actions (panic-selling, custody changes under duress) and bad inaction (failing to make transfers when the math is favorable because "it doesn't feel right"). A well-drafted IPS removes the trustee's subjective judgment from the equation and replaces it with pre-defined rules that were designed during calm conditions. If your trust doesn't have an IPS that addresses volatility events and transfer windows, draft one now — before the next witching cycle. Your estate planning attorney and a Bitcoin-literate financial advisor should collaborate on the document.
The 7-Day Action Checklist
The post-witching window is open. The Deribit expiry is six days away. Here is exactly what to do over the next seven days.
Post-Witching Estate Planning Action Plan — March 21–28, 2026
- Day 1 (Today, March 21): Call your estate planning attorney. Explain the post-witching window and the March 27 Deribit expiry. Request an emergency review of your existing trust structures and transfer capacity. If your attorney isn't Bitcoin-literate, this call will reveal that — and you'll know you need a specialist. Do not delay this call.
- Day 2 (March 22): Run the exemption efficiency comparison. With your CPA or attorney, calculate how many additional BTC you can transfer at $70K versus $85K and $100K. Use your actual remaining lifetime exemption, not the theoretical maximum. Calculate the projected future value of the additional coins at $150K, $250K, and $500K. When you see the numbers, the decision becomes mathematical.
- Day 3 (March 23): Evaluate GRAT reset. If you have an existing GRAT funded at a higher Bitcoin price, model the surplus at current price versus the original funding price. If the reset generates $500K+ in additional surplus at your target recovery price, proceed with reset paperwork. Your GRAT attorney can prepare the reset documentation in 2–3 business days.
- Day 4 (March 24): Execute annual exclusion contributions. If you have Crummey trusts or direct gift vehicles, fund them at current prices. Send Crummey notices immediately. Each $19,000 buys 0.271 BTC today — 42.6% more than at $100K. For a couple with 10 beneficiaries, that's $380,000 in Bitcoin transferred this week at maximum efficiency.
- Day 5 (March 25): Prepare irrevocable trust transfers. If the exemption math supports a large irrevocable transfer, prepare the transfer documentation. Coordinate with your custodian on the Bitcoin movement logistics. Multi-sig signing ceremonies should be scheduled for this week if possible. The goal is execution before the Deribit expiry on March 27.
- Day 6 (March 26): Pre-Deribit positioning. The $13.5B Deribit expiry hits tomorrow. If Bitcoin weakens further into the expiry, the transfer math improves. If you haven't executed yet, tomorrow may offer even better pricing. Have all documentation ready for immediate execution — sign-ready, custodian-coordinated, Crummey notices prepared.
- Day 7 (March 27–28): Execute or document. The Deribit expiry creates the second wave. If you execute transfers on or immediately after March 27, you're acting at the potential maximum weakness point. If you've already executed, document everything: contemporaneous valuations, timestamps, transaction records. If you decide not to transfer, document why in the IPS review — this creates the record that the trustee evaluated the opportunity and made a reasoned decision.

Bitcoin Mining: The Tax Strategy That Complements Every Estate Planning Move
If you're transferring Bitcoin into trusts during post-witching weakness, you should also know how to generate new Bitcoin tax-efficiently. Bitcoin mining creates deductible expenses — depreciation, electricity, hosting — that offset ordinary income, while producing an asset that benefits from long-term capital gains treatment after 12 months. For families already making estate planning moves, mining is the complementary strategy.

Frequently Asked Questions
What is quadruple witching and how does it affect Bitcoin?
Quadruple witching is the simultaneous expiration of stock index futures, stock index options, stock options, and single stock futures — occurring quarterly on the third Friday of March, June, September, and December. The March 20, 2026 event expired approximately $4.7 trillion in derivatives. While Bitcoin isn't part of equity derivatives, institutional portfolios that hold both equities and Bitcoin rebalance after witching, creating correlated selling pressure. Historically, Bitcoin has weakened 1–3 weeks after every quadruple witching over the past 18 months.
Why is the post-witching period better for estate planning than witching day?
On witching day, market makers actively hedge, providing stability. The real weakness comes after — when gamma exposure evaporates, portfolios rebalance without hedging cover, and the new options cycle hasn't built depth. Bitcoin typically holds on witching day then drifts lower in subsequent weeks. September 2025: BTC dropped from $177K to $108K in the three weeks after witching. The post-event drift is the transfer window.
Should I reset my GRAT during post-witching weakness?
If your GRAT was funded at a price 20%+ above current price, a reset can significantly increase tax-free surplus. Resetting at $70K versus $90K means the new GRAT captures $20,000 more per coin in surplus on any recovery above $90K. On a 50 BTC GRAT, that's $1 million in additional wealth transfer at zero gift tax cost. The reset is most attractive when substantial recovery is expected within the new GRAT term.
What is the March 27 Deribit expiry and why does it extend the window?
On March 27, approximately $13.5 billion in crypto derivatives expire on Deribit. Unlike equity witching, this directly involves Bitcoin options — and their unwinding creates real selling pressure in spot Bitcoin. Combined with the March 20 equity witching, this creates two sequential expiry waves that extend the weakness window through end of March or early April.
What should I avoid during post-witching weakness?
Never panic-sell Bitcoin inside an irrevocable trust — the estate planning benefit is already locked. Don't break multi-signature custody under emotional duress. Don't make irrevocable decisions without running the exemption efficiency math. And don't assume the window is permanent — the structural drivers resolve within 2–3 weeks. Act with discipline, not emotion.
