The key term here is تعثر, which in financial language means to "default" and not just "struggle," as it would in other contexts.

The other parts of the phrase can be translated in multiple ways and still be correct. For example, اضطربات could be difficulties, turmoil, etc.

Also, trying to force the يخشى معها into the translation leads to the awkward phrasing "that it is feared will...." If we want more idiomatic English, we can say "financial disruptions that could cause him to default."
