Foreign buyers of U.S. Treasury securities increased their holdings for a fourth straight month in November with holdings by China and Japan climbing to all-time highs.

The Treasury Department says total foreign holdings rose 1.1 percent in November to $5.72 trillion after a smaller 0.04 percent increase in October. Holdings had fallen from April through July but have increased since then. However, the November level of foreign holdings was still 0.1 percent below the all-time high hit in March.

China, the largest foreign buyer of Treasury debt, boosted its holdings 0.9 percent to $1.32 billion, a record level. Japan, the second-largest buyer, boosted its holdings 1 percent to $1.19 trillion, also a record.
