The West German economy did not grow as fast or as consistently in the 1960s as it had during the 1950s, in part because such a torrid pace could not be sustained, in part because the supply of fresh labor from East Germany was cut off by the Berlin Wall, built in 1961, and in part because the Bundesbank became disturbed about potential overheating and moved several times to slow the pace of growth.
Den vesttyske økonomi voksede ikke så hurtigt og stabilt i 1960'erne som den havde i 1950'erne, til dels fordi en sådan udvikling ikke kunne fastholdes, til dels fordi forsyningen med ny arbejdskraft fra Østtyskland blev stoppet med bygningen af Berlinmuren i 1961 og til dels fordi Bundesbank blev bange for en mulig overophedning af økonomien og flere gange greb ind for at reducere væksten.
