Reserves are Revised Upward, the Dollar Share Declines

Perhaps the most startling thing about the new COFER data on reserves released by the IMF is not the declining dollar share in total reserves, but rather the fact that reserves have risen relative to where we thought they were [0]. The change is entirely due to the upward revision in unallocated reserves by emerging market and LDC central banks. This point is shown in Figure 1.

Figure 1: Total reserves, in millions of US dollars (black), emerging market central banks from December 30 (bold blue), from September 30 (teal); emerging market unallocated reserves from December 30 (bold red), from September 30 (purple). NBER defined recession dates shaded gray, assumes recession ends 09Q2. Source: COFER, September 30 and December 30, 2009, and NBER.

Total reserves were revised up $381 billion in 2009Q2, as were total emerging market/LDC reserves, and unallocated emerging market/LDC reserves. The revision in total reserves constituted a 5.5% change quite substantial.

A straightforward interpretation of the data also reveals a continued — and exacerbated — decline in the identified US dollar share of total reserves.

Of course, as I and many others have observed before, a large portion of the unallocated share is in dollars. I update my figure incorporating a longer span of IMF estimates (from Chinn and Frankel (2007)).

Figure 3: US dollar share of total reserves from September 30 (red), from December 30 (blue), US dollar plus 60% of unallocated reserves from December (teal triangles), and Chinn-Frankel (2007) US dollar share series based on IMF data (dark blue). NBER defined recession dates shaded gray, assumes last recession ends 09Q2. Source: IMF, COFER, September 30 and December 30, 2009, Chinn and Frankel (2007) NBER and author’s calculations.

In this case, I’ve once again used a 60% estimate for the dollar share of unallocated. China accounts for the largest share of these unallocated reserves, and in posts from last March, Brad Setser estimates the Chinese hold 65% of their reserves in dollars — so 60% seems reasonable to me.

Taking this adjustment into account, the dollar share’s drop seems a bit less precipitous, and certainly less marked than some other movements in the past 30 years.
