"We sees the attractiveness of U.S. Treasurys falling," NPS spokeswoman, Chi Younghye, said. "The overall size of foreign bonds this year will be similar to last year's. There will be little net increase in our holding of foreign bonds for a while." She said if yields are more attractive later, the NPS would start buying again.

What will happen to Wallstreet if rates cannot be cut anymore?

Wait, are treasury yields related to rates??
