The 1950s started poorly as the club reached 2nd place behind Råå IF; several injuries to key players disturbed the season, and in 1951 the club board decided to rejuvenate the squad and which led to a 7th place. In 1952 the club yet again ended up in 2nd place, the club also went on a trip, first to Germany, where they played a series of matches, and then to the French Riviera, where the club played a game and enjoyed the weather and beach, they then returned home and played a game against Brazilian team Corinthians with a mixed team of Halmstads BK and IS Halmia players, the Brazilians won with 10–1, Sylve Bengtsson returned from the 1952 Summer Olympics with a bronze medal. 1953 saw a change in the league system and Halmstads BK was lucky as the club was able to stay only because of better goal difference as 6 teams was relegated. Things changed in 1954 as Halmstads BK dominated the new league and won promotion with 12 points ahead of IK Sleipner in second place, then made yet again a trip south, this time to North Africa and Spain, bowling was added to the club. Halmstads BK reached their best position so far in 1954–55 season as the club ended up in 2nd place, winning "Stora Silvret" (eng: The Big Silver), then during 1955–56 season, Halmstads BK biggest victory was recorded as they club crushed Västerås SK with 9–0, Östen Ståhl scored 6 goals in the match, Sylve Bengtsson also became the league's top goal scorer with 22 goals, Halmstads BK ended in 7th position. Just as in the beginning of the decade the end was far from good, the club ended up in 8th place both in 1957 and 1958, during 1958 Sweden hosted FIFA World Cup and 2 matches, Northern Ireland against Czechoslovakia (1–0) and Argentina against Northern Ireland (3–1) were played at Örjans Vall, and in 1959 the club was relegated back to Division 2 after ending up second to last.
