Scott Fullman, director of investment strategy for I.A. Englander & Co., said it was unlikely the market's downturn was because of disappointment over the rate cut or the Fed's accompanying statement, which [if anything] asserted that the central bank is willing to lower rates further if needed.

if anything (1)如果有这种情况的话,(2)如果有什么(区别)的话
在上文中，if anything 是第一个意思（如果有这种情况的话），也就是：如果有the Fed's accompanying statement这么个声明的话
第二个意思的用法如;
If anything, my new job is harder than my old one. 要说有什么不同的话，我的新工作反而比旧工作要难些。
Her family, if anything, was richer than mine.
要說有什麼區別的話,她家比我家有錢。
