Fed minutes and the October 14 CPI: how an arbitrage trader can get through a week of macro data

Fed minutes and the October 14 CPI: how an arbitrage trader can get through a week of macro data

The minutes of the Fed's September meeting came out more hawkish than expected. Most participants felt the rate will likely have to be raised once more before year-end, though they didn't name a specific meeting.

In September the rate was already raised by 25 basis points, to a range of 3.75 to 4 percent, and the decision was unanimous. Fed economists don't expect inflation to return to 2% before 2029.

What the market has priced in

Governor Christopher Waller sharpened the picture: 16 of 18 projections assume at least one more hike this year, and four assume two. Futures put the odds of a December hike at about 85%.

The next fork in the road is the consumer price index on October 14. Soft numbers could push hike odds below half and turn sentiment around, while hot ones would add pressure on risk.

What happens to spreads in the minute of release

Around macro releases the market behaves predictably. A few minutes before the data, market makers pull their orders, order books thin out, and in the first minute after the numbers the price moves at different speeds on different exchanges.

From what we see, the widest gaps last only seconds, and catching them by hand is almost impossible. They do, however, easily hurt anyone holding a leveraged trade.

How to get through the week calmly

Know the calendar. CPI comes out on October 14 at 8:30 New York time, and on October 27-28 the Fed will decide on rates, so during those hours it's better not to hold a trade on a thin margin buffer.

In our view, it makes more sense not to open new positions in the half hour before a release and not to move coins between exchanges during those minutes. We believe that after the numbers are out and order books recover, funding and basis windows often open cleaner and calmer.

Our tools

Sharp gaps in the minute of a release are only visible if you keep all exchanges in one window. Our arbitrage screener keeps dozens of venues in one window, refreshes quotes every second and shows each gap together with the volume actually behind it. The spread calculator helps you check what survives fees, network costs and slippage at your size. The bot is fully manual. It never connects to your exchange API keys.

Conclusion

The Fed minutes were hawkish: most officials are ready for one more hike, and the market prices it for December at about 85%. The next fork is CPI on October 14.

For arbitrage, a macro week means patchy order books and short spread spikes in the minute of release. It's calmer to sit out the release itself with a margin buffer and work once order books recover.
