About Helious

Helious is a live US market news service for people who trade rates. It watches the wires, the Treasury, the statistical agencies and the Fed, and publishes the number the moment it lands: the economic release with its surprise against consensus, the auction with its tail and bidder split, the yield curve with a named regime. Reading it is free.

Every US economic release, scored against forecast

When CPI, nonfarm payrolls or GDP crosses, Helious does not just repeat the number. It compares the print to consensus, sizes the surprise against how far that series normally misses, and puts the market reaction beside the headline. Every indicator keeps a permanent page with its release schedule, forecast, prior, the recent prints and a sample CSV download; the full history comes through the API. Start with the next CPI release date, nonfarm payrolls, US GDP release dates, or every indicator we track.

Treasury auction results in seconds

Helious posts the result of every US Treasury auction within seconds of the wire: the tail or stop-through in basis points, bid-to-cover against its own twelve-auction average, the indirect, direct and dealer split, and a one-word verdict of strong, in line or weak. Each tenor keeps a permanent page with years of history and a CSV. See 10-year Treasury note auction results, 30-year bond auction results, 13-week bill auction results, 4-week Treasury bill auction results, or read what an auction tail and bid-to-cover actually tell you.

The same result either way you read it. An assistant asks for it directly, no scraping.

The auction schedule and the week ahead

Every tenor page carries the date of its next auction, so the schedule is not a PDF you have to hunt down. The calendar shows the coming week of US releases and auctions with the time in ET, the forecast, the prior and the live result as it lands, and past weeks stay online at a permanent URL. See the Treasury auction schedule, this week's US economic calendar and the next FOMC meeting.

Yields, the curve regime and Fed speakers

The rates board carries the whole US Treasury curve with the day's move in basis points, the 2s10s and 3m10y spreads, and a named regime: bull steepener, bear flattener and the other two, with a deadband so a rounding error is never called a trend. Fed speakers are tracked hawkish to dovish as they talk. See Treasury yields and the curve, the 2s10s spread and Fed speakers.

How the desk works

Helious is machine-captured and methodology-governed. Data pages are generated by the capture pipeline from primary official releases and market records, not rewritten from other outlets. Every number on an indexable page traces to a primary record, and every scored read follows the published rules on our methodology page. Nothing here is investment advice.
