Banks’ exposure to govt increases


BANKS’ exposure to government have increased with 56% of CBZ bank’s assets now in Treasury Bills (TBs), First Capital Bank 41%, Standard Chartered 43%, FBC Bank 36%, ZB Bank 36%, and Ecobank 36%, supporting the notion that government default is now choking private sector lending.

Over the past few years, the government has been struggling to meet its financial obligations with some issued TBs being rolled over. However, banks have been increasing their holdings of TBs despite clear signs that the government may default. In his budget statement, Finance Minister Mthuli Ncube indicated that, apart from the 2019 budget deficit of $1,6 billion, financing needs may reach $6.5 billion as a result of maturing TBs and the projected overdraft. Given the constrained fiscal space, the government is most likely to roll-over the maturing TBs or replace them with a longer-dated sovereign paper. This is a technical default which should act as a warning to banks that are holding TBs. Government default on TBs and any sovereign paper damage banks and the real economy as banks respond by slowing down on lending to private sector. Commercial banks’ exposure to government has grown to the $10 billion mark, while lending to private sector has remained stagnant at $3.6 billion. This clearly shows how government default can be transmitted to the private sector.

A closer look at the banking sector shows that sovereign paper holdings is large for those banks that make fewer loans. When the government defaults or roll-over these TBs and any other sovereign paper, average holdings increase but more concentrated in large banks. It is the large banks such as CBZ, Standard Chartered and Stanbic that are holding the majority of sovereign paper. It is not a problem for banks to be heavily exposed to government.

However, it should be noted that during defaults, there is a large, negative and statistically significant correlation between banks’ sovereign paper holdings and subsequent lending activity.

A one dollar increase in sovereign paper is associated with as high as a 0,60 dollar decrease in bank loans to private sector.

Furthermore, about 90% of this decline is accounted for by the average paper held by banks before the default takes place. Only 10% of this decline is explained by the additional paper acquired in the run-up to and during default.
These observations support the notion that banks’ holdings of sovereign paper are an important transmission mechanism of sovereign defaults to bank lending to private sector. TBs and all forms of sovereign paper are very liquid assets that play a crucial role in banks’ everyday activities, like storing funds, posting collateral, or maintaining a cushion of safe assets. Because of this, banks hold a sizeable amount of this paper in the course of their regular business activity.

When government default strikes, banks experience losses and subsequently decrease their lending to private sector to manage the remaining liquidity. During these default episodes, moreover, some banks deliberately hold on to their risky paper, while others accumulate even more. This behaviour could reflect banks’ reaching for yield or it could be their response to government moral suasion or bailout guarantees.

Whatever its origin, this behaviour is largely concentrated in a set of large banks and is associated with a further decrease in their lending to private sector. Balance sheet analysis of banks such as CBZ, Standard Chartered and Stanbic supports this notion. CBZ has significantly reduced its exposure to private sector by more than 60% in the year to September, while aggressively acquiring TBs and other government bonds despite signs that Government may default.

Generally, sovereign paper holdings, regardless of whether they are accumulated before or during sovereign default events, contribute to transmitting the effects of defaults to private loans. The current decline in loans to private sector growth points to past aggressive issuance of TBs and bonds by the government.
