Could a Royal Navy exercise have deterred escalation?

What effect would a major Royal Navy exercise in the North Sea during mid-July have had?

It would have demonstrated British readiness and could have reinforced financial pressure for de-escalation.

A fleet demonstration does not guarantee peace, but it removes ambiguity about Britain's willingness and ability to act. The idea follows the combined economic and naval pressure used during the Agadir Crisis, where a financial shock and visible fleet readiness reinforced each other.
