Deutsche Bank Paper Advocates for Holistic FX Hedging
Posted by Colin Lambert. Last updated: June 1, 2026
A new paper published by Deutsche Bank advocates for an approach to currency hedging by investors that “moves beyond static extremes” and that allows both the mitigation of risk associated with FX volatility, as well as the opportunity to capture returns.
The paper, Dynamic FX Portfolio Hedging: A deep dive and why you should use it, is authored by Rohini Grover, strategist at Deutsche Bank, and Vivek Anand, quant strategist at the bank, and stresses that “Understanding currency hedging is important for all participants engaged in FX, whether for operational purposes or for alpha generation.” It also promotes a Total Portfolio Approach (TPA) to investor currency management that holistically integrates FX hedging as a dynamic overlay.
The TPA methodology involves a two-step process – first, establishing a strategic, long-term hedge ratio based on total portfolio structural risks to minimise long-term portfolio risk; and second, implementing a tactical overlay that dynamically adjusts hedge ratios around this anchor using signals like carry and momentum. “This allows mitigation of unrewarded volatility and capture of return opportunities,” the authors write.
The paper deals with four core factors driving hedging decisions, correlation, relative asset/FX volatility (which it says is “the most crucial factor”), intra-FX correlations, and the current cost of hedging. It observes that traditionally FX hedging has taken a more silo-based approach, favouring a more static approach of not hedging, applying a static hedge ratio of 50% unanimously across the portfolio, or fully hedging. “This sort of approach ignores the interaction between different asset classes and FX, and within FX,” the authors argue, adding, “It is also capital inefficient as it views the same currency exposure differently across different assets.”
While a 100% currency hedge would appear to provide total protection for investors, the paper argues this is not necessarily the case if equity markets and exchange rates are correlated, but it also notes that those conditions certainly warrant more hedging due to amplified risks. By viewing the hedging problem at the portfolio level, investors are able to either focus on minimising portfolio risk, maximising portfolio returns via FX carry, or a combination of both risk and return.
The authors test their approach by using a EUR-based investor, whose exposure to US equities means they are simultaneously exposed to movements in both equity and FX markets. The paper studies the different influences in depth and also provide insight into the impact of different spot views, including no view on spot in a carry/non-carry environment. It finds that dynamic hedging strategy achieves superior risk-adjusted outcomes than static hedging, and that strategies embedding volatility and correlation structures adapt to deliver better risk-adjusted returns than static hedging. “These results align with FX hedging for corporations,” the authors observe.
Looking at their results, the authors observe that a historical portfolio optimisation based on data from 2000-2026 (using three-year rolling correlations and volatilities) conducted monthly highlights the superiority of a dynamic, portfolio-aware approach. “We find that dynamic strategies consistently deliver better risk-adjusted returns than static alternatives,” they write. “Moreover, within a dynamic framework, the risk-minimising strategies outperform a carry-maximising strategy. This suggests investors are better off prioritising portfolio volatility over FX carry.”
Implications
The paper also offers thoughts on the implications for different investor types. For asset managers, the authors observe that in addition to advocating for holistic currency hedging, the proposed framework also addresses specific market challenges, notably “while negative carry historically deterred hedging volatile emerging market currencies, our framework demonstrates that carry is not the sole determinant of optimal hedging”.
They add, “Strategies explicitly maximising carry gains have not consistently led to superior outcomes, reinforcing the need for a more dynamic and holistic approach, especially for EM currencies. Conversely, for currencies with low volatility but fatter tail risks (e.g., Asian pairs), where operational challenges exist, tactical hedging via cheaper onshore forward markets can improve efficiency.”
As far as macro, Alpha-seeking, investors are concerned, the paper argues “understanding currency hedging is crucial” as it can drive FX movements and impact market dynamics in the short and long-term, thus providing opportunities for these participants. As an example, the authors point to the many pension funds that adjusted hedge ratios as US asset-dollar correlation turned positive last April, “illustrating the potential for significant, albeit less frequent, FX dislocations driven by strategic hedging adjustments”.
The paper concludes by citing work by Deutsche Bank that shows that while 45% of the FX spot market seeks Alpha, 55% is serving, hedging, or international investments, functions. “For predominantly operational FX, electronification offers increased automation, crucial given rising regulation and management fee compression,” the authors state. “Our hedging framework highlights an automated path to greater efficiency.”
The Full FX View
While there are signs in the industry – mostly anecdotal – that investors are paying more attention to the currency exposures, it is important that the banking industry in particular – with its extensive research resources – maintains the discourse over the benefits of currency hedging.
There is a body of research, which is being added to regularly, that should be heeded by non-hedgers, because it clearly shows the benefits of the practice, which then makes the decision one of cost. In terms of local resources, at the very base, investors merely need automation, this is not about extra staff to do the hedging (although I would argue a professional FX hedging team is worth its weight in gold). A connection to a platform, an internal system that generates the hedging requirement(s), and most of the work is done – the rest can be plug and play.
Of course, this is a process that this paper argues – rightly – against, but as I am sure someone has said somewhere (If not I’ll claim it!) hedgers have to start somewhere. By getting more investors (and corporates) hedging, the industry is bringing in more business but also providing a benefit to the wider investor pool.
Once the practice is more widespread, then processes advocated by Deutsche in this paper come into play, and it is for firms to decide individually what the cost of implementation will be. Whatever it is, however, will probably be worth it, because markets are inter-linked in a more complex manner now and correlations emerge and breakdown almost daily it seems.
In such an environment an investor needs to be on their toes, which does take up resources, hence why the process suggested here is important. Just as firms can establish a simple currency hedging programme, once that is done, then more sophisticated programmes can be implemented – and run just as easily in the background with minimal effort. It would be just as easy, arguably, to go straight from no hedging to a sophisticated such as that laid out in the paper.
Papers like this, however, highlight the importance of sensible, intelligent, currency management, no matter what the approach to the subject. They also carry a message the FX industry needs to continue to promote; yes, there is a cost to FX hedging, but it is not as high as many think, and when done smartly, can save much more than it costs.
