Under common zero-to-one hedge-ratio mandates, many emerging-market exposures are already clipped to a full hedge, leaving little room for estimator choice to improve the implemented position. Developed markets provide more active partial-hedge decisions. A Bayesian rule combining rolling return information with trade orientation, carry, and momentum improves implementation by reducing turnover where the hedge remains active. The rule also produces smoother hedge paths and posterior intervals that convert estimation uncertainty into a governance input for currency-hedging policy.<\/jats:p>","DOI":"10.2139\/ssrn.7095878","type":"posted-content","created":{"date-parts":[[2026,7,14]],"date-time":"2026-07-14T08:21:02Z","timestamp":1784017262000},"source":"Crossref","is-referenced-by-count":0,"title":["Managing
