The holder of a corridor option receives a coupon at maturity, the magnitude of which depends on the behaviour of a specified spot rate during the lifetime of the corridor. For each day on which the spot rate (typically an official fixing rate) remains within the chosen spot range (the accrual corridor), the holder accrues one day’s worth of coupon interest. A variation is the knock-out corridor option. In this structure, the holder ceases to accrue coupon interest as soon as the spot rate leaves the range. Even if the spot rate subsequently re-enters the range, the holder does not continue to accrue coupon interest.
A wall option is a special type of corridor option, where the accrual corridor is one-sided. Another relative is the range binary, a digital option that pays a fixed-coupon amount if the rate stays within the range, but pays nothing if the range is breached.

The Energy Risk Glossary, now in its eighth edition, provides an at-a-glance explanation of the myriad specialised terms and acronyms used in energy trading and risk management.
This year, the guide has been updated by Aviv Handler of ETR Advisory. Energy Risk would like to thank him for his input into this edition, which benefits greatly from his valuable experience and insight into energy markets.
The fast-changing nature of these markets means much has changed since our last edition – almost 200 new entries and revisions have been made this year. Reflecting the increasing importance of regulation, definitions of the Markets in Financial Instruments Directive (MiFid) and the Ljubljana-based Agency for the Cooperation of Energy Regulators (Acer) make it into the glossary for the first time. A focus on improving back-office infrastructure and mitigating counterparty risk is also apparent from the inclusion of terms such as ‘portfolio reconciliation’ and ‘portfolio compression’.
The glossary is extensively cross-referenced, making for easy and thorough searches. We hope you find it useful.
