US inflation rises in March, energy costs surge amid Iran conflict

US inflation hit 3.3% for March 2026, up from 2.4% in February, driven primarily by energy costs tied to the US-Iran conflict. Bitcoin’s odds of being above $66,000 on April 21 sit at 99.9% YES on Polymarket, but a 15% expected move suggests potential volatility ahead.

## Market reaction

The Bitcoin above $66K on April 21 contract is near certainty at 99.9% YES, yet the inflation spike introduces pullback risk. Volume over the last 24 hours is $1,438,192 in USDC. A higher inflation rate typically points toward tighter monetary policy, which could push traders into risk-off positioning and weigh on Bitcoin.

The ECB market for a 50+ bps rate decrease is also under pressure, though its direct effect on Bitcoin pricing is limited. Cross-Atlantic economic spillover remains possible but indirect.

## Why it matters

Traders should treat the inflationary jump as a structural shift rather than a one-month anomaly. At 99.9% YES for Bitcoin above $66,000, the market is pricing in stability, but the 15% expected move shows traders are hedging. A YES share priced at 99.9¢ barely offers a 1.00x return, making the risk/reward asymmetric on the downside.

## What to watch

Watch for Fed statements or comments from Michael Saylor. If inflation fears translate into monetary tightening, Bitcoin’s current odds could shift. The Bureau of Labor Statistics’ next release is the key data point that could swing positioning.
