Why This Comparison Matters
Bitcoin closed at $78,126 on April 24, 2026, down 38 percent from its $126,198 October 2025 peak. TLT closed at $86.71 on April 22, with the 30-day SEC yield at 4.86 percent reflecting elevated long-end rates. The pair connects two assets with opposite-seeming characteristics: bitcoin is non-yielding, scarce, and inflation-hedging; TLT yields nominal coupons and gets crushed by inflation. Both share interest-rate sensitivity through different channels: TLT through nominal long yields, bitcoin through real rates and liquidity. The April 2026 configuration shows bitcoin compressed from peak while TLT has held a tight $83 to $92 range, a divergence reflecting Iran-driven risk-off plus stable rate expectations.
What TLT and Bitcoin Capture
TLT is the iShares 20+ Year Treasury Bond ETF, holding US Treasury securities with remaining maturities greater than 20 years. April 2026 price $86.71, 30-day SEC yield 4.86 percent, 12-month trailing yield 4.51 percent. The fund has $42.75 billion AUM, expense ratio 0.15 percent, and modified duration of approximately 17 years. A 100 basis point rise in 20-year yields would compress TLT by approximately 17 percent; a 100 basis point fall would expand it by similar amount. TLT is the deepest, most liquid US-listed long-duration Treasury ETF.
Bitcoin is the original cryptocurrency with hard-capped supply of 21 million coins (about 19.85 million already mined as of April 2026). Total market capitalization in April 2026 is approximately $1.55 trillion. Bitcoin pays no yield. Its valuation is driven by future adoption growth, store-of-value demand, and macro liquidity dynamics. The two assets sit at opposite ends of the yield-and-duration spectrum but share underlying rate sensitivity through different transmission channels.
The Real Rate Connection
Both bitcoin and TLT respond to real interest rates (nominal yields minus inflation expectations), but in different ways. TLT directly tracks long nominal yields: when 20-year yields rise, TLT falls; when they fall, TLT rises. Bitcoin responds to real rates and the broader liquidity regime: low real rates make non-yielding assets more attractive (bitcoin gains relative value), high real rates make them less attractive.
The 90-day rolling correlation between BTC and TLT has averaged 0.30 over 2024 to 2026, lower than BTC-SPY (0.45) or BTC-QQQ (0.55). The lower correlation reflects the different transmission mechanisms: TLT is mechanically tied to nominal yields; bitcoin is tied to broader macro conditions including real rates, dollar strength, and global liquidity. The two are positively correlated during pure rate cycles (both rally when Fed cuts; both fall when Fed hikes) but can diverge during episodes where inflation expectations shift independently of nominal yields.

Frequently Asked Questions
What is the BTC-TLT correlation?+
The 90-day rolling correlation between bitcoin and TLT has averaged 0.30 over 2024 to 2026, lower than BTC-SPY (0.45) or BTC-QQQ (0.55). The correlation has varied substantially by regime: 2020 to 2021 saw negative correlation as bitcoin rallied while TLT fell on inflation expectations, 2022 saw positive correlation at 0.55 as both fell together during Fed hiking, 2024 to 2025 returned to a more neutral pattern. The 30-day rolling correlation in April 2026 is 0.2, low by historical standards, reflecting the unusual environment of bitcoin compressed from peak with TLT range-bound on stable rate expectations.
What does TLT hold and yield?+
TLT (iShares 20+ Year Treasury Bond ETF) holds US Treasury securities with remaining maturities greater than 20 years. April 2026 price $86.71, 30-day SEC yield 4.86 percent, 12-month trailing yield 4.51 percent. Modified duration is approximately 17 years, meaning a 100 basis point rise in 20-year yields would compress TLT by approximately 17 percent. Fund AUM is $42.75 billion, expense ratio 0.15 percent. TLT is the deepest, most liquid US-listed long-duration Treasury ETF and the standard benchmark for long-duration rate exposure.
Is bitcoin really an inflation hedge?+
Empirically, mixed. The 2022 inflation cycle saw bitcoin fall 78 percent peak to trough while CPI peaked at 9.1 percent. If BTC was a pure inflation hedge, it should have rallied. Bitcoin's rate sensitivity (compressed by Fed hiking) overwhelmed its inflation-hedge property when both operated simultaneously. By contrast, gold rose 30 percent from 2021 to 2022 during the same inflation episode. The "digital gold" thesis for bitcoin remains contested, with the asset functioning more like a high-beta tech proxy than a pure inflation hedge in current regimes. For investors seeking inflation protection, gold has been substantially more reliable through the 2022 to 2026 cycle.
