In his book, Mass Confusion
, Jimmy Akin says the following:
“The Holy See has not ruled directly on this issue. In a response to a query, however, the Holy See stated that holding hands “is a liturgical gesture introduced spontaneously but on personal initiative; it is not in the rubrics” (Notitiae 11  226, DOL 1502 n. R29). For this reason, no one can be required to hold hands during the Our Father.”
(Nor is the orans posture in the rubrics.)
The U.S. Status:
People hold hands during the Our Father (p. 161)—Discouraged
Appendix Three pg. 234)
In the new General Instruction of the Roman Missal the only posture specified during the Our Father is standing.
(paragraphs 43 and 160)
Before the reading of the Gospel, the faithful should make the sign of the cross on the forehead, mouth, and breast.
