Bond Field Guide is an educational and research tool only. It is not
investment, financial, legal, or tax advice, and nothing on this site is a recommendation, offer, or
solicitation to buy or sell any security.
Every price and yield is an indicative model estimate computed from a public Treasury
curve. It is not a quote, an executable price or a last-traded value. Figures may be inaccurate,
delayed or incomplete, and come with no warranty of any kind.
The data and identifiers are not ours. CUSIP numbers, credit ratings, company names,
logos and financial figures are the property of their respective owners (including CUSIP Global
Services, the rating agencies and the issuers). We do not own, sell, license or guarantee them. We point
you to the official public sources, such as SEC filings, where the real numbers are published.
Always verify before acting. Confirm any bond's real terms, CUSIP, and price in the
official prospectus and with your broker, and consult a licensed professional before making any
decision. We are not a broker-dealer, investment adviser, or fiduciary.
Use at your own risk. To the fullest extent permitted by law, Bond Field Guide and its operators
accept no liability for any loss, damage, or decision arising from information shown on, or linked from,
this site.

Where this comes from.
Portugal's 10-year and 3-month rates here are the OECD's latest monthly figures. For a live curve
and the actual tradeable bonds, consult Portugal's national debt-management office or central bank.
10-year: OECD (monthly) (monthly), as of Sep 2026.
3-month: OECD (monthly), Sep 2026.
Values are taken from official government publications where available, or from the OECD's Long-term interest
rates dataset, which reproduces official national statistics and is licensed
CC BY 4.0.
Benchmark methodologies differ between countries, so yields are broad reference levels, not perfectly comparable
market quotes. All are indicative and for research only; none is a live, executable or last-traded price.
