Debunking the mandatory credit rating misconceptions

There have been growing concerns that Vietnam’s fast-growing corporate bond market is harbouring financial risks. The single most important step that the government could take to improve the transparency, safety, and sustainability of the corporate bond market is to mandate public credit ratings for all publicly and privately traded bonds.

Under the 2019 Law on Securities, the government introduced some mandatory ratings. However, the regulations were tightly scripted and would mandate few, if any, issuers to be rated.

Expanding the regulations to encompass all bonds is controversial, and opponents raise several objections. However, these are based on misconceptions and should not prevent a move to the greater transparency that mandatory credit ratings would introduce.

The first misconception is that rating agencies are not reliable. During the global financial crisis of 2008-2009, bonds rated AAA, the highest rating available, defaulted. Many wondered what value mandatory credit ratings have if they are not reliable?

Indeed, credit rating agencies did perform poorly during that financial crisis. In particular, they performed miserably in rating asset-backed securities for myriad reasons including inherent complexity, lack of historical data, conflicts of interest, and an over-reliance on models.

However, Vietnam does not have securitised instruments. Bonds are often collateralised and noncomplex. Rating agencies have a strong track record, including during the financial crisis, in assessing the performance of such instruments.

Rather than disputing whether ratings are necessary, the more imminent priority is to attract global rating agencies to the Vietnamese market. They have partnered with local credit rating agencies in many emerging markets and have helped to develop these local agencies into reliable appraisers of credit risk.

We should also rethink the assumption that credit ratings are expensive. Yes, credit ratings will entail upfront and annual fees. However, in comparison to the overall issuance costs, which can include underwriter, agent, legal, accountant and other fees, these are relatively small – several basis points of the initial issuance and annual fees ranging between $30,000 and $60,000.

In the short term, the issuer can recover these costs through lower interest rates, for investors will typically reward transparency by charging less. In the longer term, a well-performing, transparent bond market attracts capital inflows and lowers the cost of capital for all issuers, and therefore can be a boon to economic growth.

It is also a mistake to think that regulatory mandates could reduce demand for bonds. The worry here is usually that if the government raises the bar for issuing bonds too high, issuers will turn to other sources of funding. However, this has not happened in other developing markets. Thailand, Indonesia, the Philippines, India, and China all mandate credit ratings. These are some of the most dynamic capital markets in Asia.

Rather, credit ratings can build demand. They spur institutional investors to enter the corporate bond market and encourage retail investors to move beyond bank deposits and government securities into more profitable investments.

Might some riskier issuers shun the bond market because a credit rating would expose their weaknesses? Yes, but that would be the rating agencies doing their job.

The fourth misunderstanding is that local credit rating agencies are not ready. There are presently only two licensed domestic credit rating agencies in Vietnam. If ratings are mandated, do they have the sophistication and capacity to handle the demand?

In short, yes. Indeed, many more agencies could make the market unattractive given its small size. One of the licensed agencies, FiinRatings, has been actively issuing credit ratings since May 2021 and has recently benefited from an agreement with S&P Global Ratings to receive technical training through an Asian Development Bank technical assistance project funded by Australia’s Department of Foreign Affairs and Trade.

Additionally, public sources report that the Vietnam Bond Market Association is facilitating the establishment of a third local credit rating agency that is backed by several of its members plus a global credit rating agency. Additionally, the Vietnam Bond Market Association is facilitating the establishment of a third local credit rating agency.

Even if the expertise is not available now, it could start in a couple of years, which would give local and global credit rating agencies not only the time but, more importantly, the incentives to invest in their operations and ramp up their capacity. Indeed, the absence of such a regulatory signal explains much of the slow development of domestic credit rating agencies in Vietnam.

Finally, it is not always the case that privately traded bonds should enjoy lighter regulation. The premise of this argument is that privately traded bonds should have laxer rules than publicly traded ones because they pose less risk to retail investors.

This is true in markets where privately traded bonds are a small portion of all bonds. However, privately traded bonds constitute over 90 per cent of Vietnam’s bond market. Mandating ratings only for public issuances would further incentivise issuers to avoid public placements. Moreover, there is no limit to the number of professional investors who can invest in a private placement, and the criteria to become a professional investor are lower than in other markets.

As such, retail investors are exposed. In this regard, India is a good model. Like Vietnam, private placements constitute more than 90 per cent of the bond market – but unlike Vietnam, India mandates that, with few exceptions, these issuances must be rated.

There will be resistance to mandatory credit ratings. But not from businesses with strong fundamentals that will benefit from a more transparent capital market, nor from investors who will benefit from additional protection.

Moreover, the mandate need not be permanent. Malaysia required credit ratings up until 2016. By then, the credit culture had become so ingrained that today, issuers continue to be rated even though there is no longer a mandate to do so. By jettisoning the misconceptions, Vietnam can follow a similar course.
