DBS is the single cleanest beneficiary of capital, deposits and family offices relocating into Singapore — it is the dominant Singapore bank with the largest wealth-management and private-bank franchise, so AUM growth, fee income and deposit inflows from departing Swiss/London money land directly on its book. As the thesis plays out, DBS reprices far harder than any broad Singapore index. Size as a core position (e.g. 10-15% of a thematic sleeve).

If Singapore replaces the legacy hubs, the listing venue, FX and derivatives trading, and clearing flow migrate to SGX — the exchange operator monetises rising listings, record FX/derivatives volume and the gravitational pull of Asia's wealth center. It is a high-margin, toll-booth bet on the hub shift itself rather than on any single financial firm.

The currency expression of 'London declines, Singapore rises': structural capital inflows plus MAS's appreciating-NEER bias support the Singapore dollar, while a fading London hub and UK risk premium weigh on sterling. Shorting GBP/SGD captures both legs of the relocation in one liquid pair without single-stock risk.

UBS is the embodiment of the Swiss wealth-management hub — after absorbing Credit Suisse it IS Swiss private banking, so an erosion of trust in Switzerland and AUM bleeding to Singapore hits UBS's core franchise and fee base most directly. The cleanest single-name short on the 'Switzerland loses' half of the thesis. Consider expressing via long-dated puts to cap downside instead of an outright short.
