Chinese property developers (Losers). Stock prices of Chinese property development companies have taken a major hit since Tuesday's announcement. For starters, the hike is meant in large part to put a damper on China's real estate market, and property developers would feel the pain from decreased demand in that sector. Additionally, higher interest rates drive up the cost of borrowing, which makes it harder for property developers (and other companies that require access to loans) to raise capital.
Clarification: The first paragraph of this article has been clarified to indicate that interest rates increased by 25 basis points as opposed to 0.25 percent of their previous values.
