Why the times suit active fixed interest

It is hard to believe, but back in August 1982, the Australian cash rate averaged 17% (the unofficial rate went as high as 19%) and the yield on a 10-year Australian government bond was 16.5%. Some 35 years later, the cash rate is 1.5% and the yield on a 10-year government bond is around 2.6%.

Over this period, the Australian fixed interest sector has been in a structural bull market, propelled by the shift from a high to low inflation environment and demographic factors which lowered real rates. More recently, conventional and unconventional monetary easing has driven yields even lower.

For investors in the sector, the last 35 years have generated handsome returns, even allowing for the 1994 bond bear market. Returns of 9.5% p.a. compare favourably to 12% p.a. from the Australian share market and 7.6% p.a. from cash over this period.

Beware the bull complacency trap

A common trap that investors can fall into is becoming complacent about the risks that may be building up in their sector exposures after a prolonged period of structural change and good returns.

With the global economy enjoying a cyclical recovery and central banks signalling a desire to begin withdrawing high levels of policy accommodation, investors’ attention should focus on two sources of risk embedded in the sector benchmark, the Bloomberg AusBond Composite 0+ Yr Index (benchmark) that have built up progressively since the GFC.

Lengthening benchmark duration = more interest rate risk

Just because the level of interest rates is low by historical standards does not mean that a small rise in rates will have a limited impact on sector returns. Investors need to be aware that since 2009, the duration (a measure of maturity term) of the Australian fixed interest sector has risen from around three years in mid-2009 to around five years currently.

In 2009 when bond market yields averaged around 5.5% and duration was three years, investors’ exposure to interest rate risk was such that a 1% rise in bond yields would have resulted in capital loss of 3%, delivering a total return of around 2.5% (i.e. the income of 5.5% minus the capital loss of 3% from rising bond yields).

Today, with average bond market yields of around 2.5% and the duration of the benchmark around five years, a 1% rise in bond yields would result in capital loss of 5% delivering a total return of -2.5% (i.e. 2.5% income less 5% capital loss). A 0.5% lift in yields would result in flat returns (i.e. 2.5% income less 2.5% capital loss).

With the RBA Governor indicating that the next move in rates is likely to be up, investors need to be mindful of the interest rate risk in the sector benchmark. Over the last few years, investors in passive fixed interest products have enjoyed a good run as interest rates fell and the duration of the benchmark lengthened.

Looking ahead, investors in such strategies need to be aware of their exposure to capital loss from even modest rises in rates. By way of example, the yield to maturity on the benchmark lifted from 1.98% at the end of July 2016 to 2.43% at the end of July 2017. With the duration of the benchmark at historically high levels, resultant capital loss more than offset any income, with returns down 0.24% over the period.

We believe active fixed interest strategies or absolute return strategies, where managers are not bound to hold duration at benchmark levels, are better positioned to preserve investors’ capital in a rising rate environment.

Benchmark compositional risk: lower-returning government debt, less diversification

Since the GFC, there has been significant change to the composition of the Australian fixed interest benchmark. The heavy issuance of increasingly longer-dated government debt (federal, state, supra national) combined with corporate deleveraging has hastened the ‘crowding out’ effect in the benchmark. As a result, the market weight of the higher-yielding credit sector in the benchmark has fallen from 36% in 2008 to around 8% in 2017 currently.

Investors in passive index strategies have progressively lost access to both the higher yields available in the credit sector and diversification benefits of broader holdings in the benchmark. Longer-dated government debt has increased the interest rate risk. The past year highlights the importance of active interest rate management in navigating the gradual reversal of the bond bull market.

I'm going to sound like a broken record, but the attractive returns have not been because of falling yields or 'a bull market'. Bond market returns have actually declined because of falling yields. The hint is in the article itself - at the start of the 35 year period ten year bonds paid an annual return of 16.5%. That the average return over the 35 years since has been only 9.5% is because yields declined through time. If we hadn't had this alleged "bull market" we'd have had average returns over 35 years of 16.5%.

I do have sympathy with the general premise of the article, because it's unusual for any bond index to align closely with investor risk preferences for term or default risk composition. But the old 'structural bull market' argument is not only not necessary for making the case, it's actually factually incorrect that such a thing has happened.

The flip side is that, though bond yields are now only around 2.5%, if they rise over the next decade or two or three, bond returns will increase. All the fear about how 'bad' it will be for investors if rates go up will be long forgotten then - the short term decline in capital values will be swamped by increased reinvestment income and higher coupons down the track.

Perhaps you need a career that has spanned a 35 year period to be able to take a 35 year view like I do, but I can honestly say looking back over 1982-2017 that all the short term bull and bear markets in bonds are just noise. The driver of the returns from this asset class is income, not capital.

Yes, active managers in theory should "preserve capital" in a rising rate environment - and bravo if you do. But my memory of, say, the 1994 bond sell-off is that the biggest mistake active bond managers made was that they didn't go long duration again at 10% yields in 1995. Looking back, the income foregone by not jumping on board then was far more significant than the short term capital lost by not having been short in 1994.
