Forex Markets Rush to Buy USD Call Options After Fed's Hawkish Decision
0xBroomberg
After new Fed Chair Kevin Warsh struck a hawkish tone, hedge funds rushed into dollar call options, pushing the Bloomberg Dollar Spot Index up 1% over two days — markets have now fully priced in a 25-basis-point hike before October, a sign that rate expectations are being rewritten.
Who is buying, and what exactly?
Leveraged accounts — primarily hedge funds — began snapping up dollar call options (contracts that pay off if the dollar keeps rising) on Wednesday, with demand carrying into Thursday.
Tobias Jungmann, Bank of America's Americas head of FX options, said "we are seeing significant dollar call buying," concentrated in G10 currency pairs.
This means → this is institutional-scale directional betting, not retail follow-through — unusual in both size and concentration.
How extreme are the numbers?
Dollar call volume against sterling jumped to more than five times put volume, per CME Group data.
EUR/USD options volume hit its highest since March 3; large-notional call contracts (≥€200 million, roughly $229 million) traded at roughly twice the rate of equivalent-sized puts, per DTCC data.
In plain terms = big money is not just "leaning bullish on the dollar" — it is placing outsized bets through large-ticket contracts.
Why use options instead of buying dollars outright?
Jungmann noted that implied volatility — the market's gauge of expected price swings — sits at low levels, making option-based dollar longs "quite attractive."
Barclays senior FX options trader James Swindell added that demand is expressed through vanilla options (no special conditions) and digital options (which pay a fixed amount if the pair hits a preset level at expiry).
This means → low volatility = cheap options. Institutions are using relatively low premiums to lever up large directional positions.
Why is the yen the exception?
On USD/JPY, the bull-bear split is notably balanced — clients betting on further dollar/yen strength are offset by those betting on a sharp reversal after Japanese authorities intervene.
The yen has weakened to its lowest against the dollar since July 2024; Finance Minister Satsuki Katayama said Friday that the government "can take bold action" against speculative moves.
This reflects a market that is not blindly long the dollar — on the yen leg, intervention risk is actively capping one-way bets.
What is the core logic behind this wave of bets?
Treasury futures saw record-breaking volume at the same time, pointing to the same conclusion as the FX options market: Warsh's hawkish stance is reshaping rate expectations.
Markets have now fully priced in a 25-basis-point Fed hike before October.
In plain terms = two markets are shouting the same thing — "rates are going up." Whether the dollar rally can last ultimately depends on whether incoming inflation data support the hike actually happening.
