We showed in many of our charts that 2017 was the year where some of the strong correlations between assets classes broke down. We showed USDJPY vs. TOPIX (here, here), Cable (here) and EURUSD (here) vs. the 2Y and 10Y interest rate differentials, and this week we chose to overlay Gold prices with 5Y US real interest rates. As we explained it in our study on Gold (here), the relationship between Gold and US [real] rates is easy to understand. The precious metal is a non interest-bearing asset, meaning that a typical investor doesn’t get any cash-flow from owning it (unlike dividends for stocks and coupons for bonds), and has usually a storage cost associated with it. Therefore, the forward curve of the ‘currency of the last resort’ (Jeffrey Currie) is usually upward sloping, in other words Gold market is in contango, with the forward price equal to the following:
Hence, if real interest rates start to rise, a rational investor would prefer to reallocate his wealth to either US Treasuries or Treasury Inflation Protected Securities (TIPS) and receive coupons rather than keeping a long position in a commodity that has a ‘negative carry’.
As you can see it on the chart, Gold prices (in US Dollars) and the 5Y TIPS real yield have shown some strong co-movements over the past 5 years, until the summer of 2017 when the two times series diverged. If we would follow recent moves on the market, the late surge in Gold prices (currently trading at 1,340 $/ounce) would imply a 50 to 60 bps decrease in US real interest rates (note that if we regress the change in Gold prices on the change in the 5Y real yield using weekly data since 2013, we find that a 1% increase in real yields lead to an 8.7% depreciation in Gold prices). And lower real rates would either come from higher inflation expectations or lower nominal interest rates. With the 5Y5Y forward inflation swap currently trading at 2.11% and up 30bps over the past 6 months, core inflation and core PCE YoY rates at 1.8% and 1.5% slightly moving to the upside, and oil prices still trending higher with WTI front month contract trading at $64.5, there is room for higher inflation prints coming ahead. However, if the two curves were to converge in the short term, the [sharp] move would come from either [lower] Gold prices or [lower] Treasury rates.
Our view is that the divergence will persist in the beginning of 2018, with inflation remaining steady / slightly increasing and US interest rates failing to break new highs on the long end of the curve (5Y and 10Y). The main reason for that is that we think market’s confidence on the Fed’s 4 or plus hikes will slow down in the coming months on the back of lower-than expected fundamental, depriving the yield curve from steepening too much.
